Six decades have now passed since some of the most iconic Project Gemini spaceflights. The 60th anniversary of Gemini 4, when Ed White conducted the first US spacewalk, came in June. The next mission, Gemini 5, ended just two weeks ago, in 1965. These missions are now forgotten by most Americans, as most of the people alive during that time are now deceased.

However, during these early years of spaceflight, NASA engineers and astronauts cut their teeth on a variety of spaceflight firsts, flying a series of harrowing missions during which it seems a miracle that no one died.

Because the Gemini missions, as well as NASA’s first human spaceflight program Mercury, yielded such amazing stories, I was thrilled to realize that a new book has recently been published—Gemini & Mercury Remastered—that brings them back to life in vivid color.

The book is a collection of 300 photographs from NASA’s Mercury and Gemini programs during the 1960s, in which Andy Saunders has meticulously restored the images and then deeply researched their background to more fully tell the stories behind them. The end result is a beautiful and powerful reminder of just how brave America’s first pioneers in space were. What follows is a lightly edited conversation with Saunders about how he developed the book and some of his favorite stories from it.

Ars: Why put out a book on Mercury and Gemini now?

Andy Saunders: Well, it’s the 60th anniversaries of the Gemini missions, but the book is really the prequel to my first book, Apollo Remastered. This is about the missions that came before. So it takes us right back to the very dawn of human space exploration, back to the very beginning, and this was always a project I was going to work on next. Because, as well as being obviously very important in spaceflight history, they’re very important in terms of human history, the human evolution, even, you know, the first time we were able to escape Earth.

For tens of thousands of years, civilizations have looked up and dreamt of leaving Earth and voyaging to the stars. And this golden era in the early 1960s is when that ancient dream finally became a reality. Also, of course, the first opportunity to look back at Earth and give us that unique perspective. But I think it’s really the photographs specifically that will just forever symbolize and document at the beginning of our expansion out into the cosmos. You know, of course, we went to the Moon with Apollo. We’ll go back with Artemis. We spent long periods on the International Space Station. We’ll walk on Mars. We’ll eventually become a multi-planetary species. But this is where it all began and how it all began.

Ars: They used modified Hasselblad cameras during Apollo to capture these amazing images. What types of cameras were used during Mercury and Gemini?

Saunders: Mercury was more basic cameras. So on the very first missions, NASA didn’t want the astronaut to take a camera on board. The capsules were tiny. They were very busy. They’re very short missions, obviously very groundbreaking missions. So, the first couple of missions, there was a camera out of the porthole window, just taking photographs automatically. But it was John Glenn on his mission (Mercury-Atlas 6) who said, “No, I want to take a camera. People want to know what it’s going to be like to be an astronaut. They’re going to want to look at Earth through the window. I’m seeing things no humans ever seen before.” So he literally saw a $40 camera in a drugstore on his way after a haircut at Cocoa Beach. He thought, “That’s perfect.” And he bought it himself, and then NASA adapted it. They put a pistol grip on to help him to use it. And with it, he took the first still photographs of Earth from space.

So it was the early astronauts that kind of drove the desire to take cameras themselves, but they were quite basic. Wally Schirra (Mercury-Atlas 8) then took the first Hasselblad. He wanted medium format, better quality, but really, the photographs from Mercury aren’t as stunning as Gemini. It’s partly the windows and the way they took the photos, and they’d had little experience. Also, preservation clearly wasn’t high up on the agenda in Mercury, because the original film is evidently in a pretty bad state. The first American in space is an incredibly important moment in history. But every single frame of the original film of Alan Shepard’s flight was scribbled over with felt pen, it’s torn, and it’s fixed with like a piece of sticky tape. But it’s a reminder that these weren’t taken for their aesthetic quality. They weren’t taken for posterity. You know, they were technical information. The US was trying to catch up with the Soviets. Preservation wasn’t high up on the agenda.

This is not some distant planet seen in a sci-fi movie, it’s our Earth, in real life, as we explored space in the 1960s. The Sahara desert, photographed from Gemini 11, September 14, 1966. As we stand at the threshold of a new space age, heading back to the Moon, onward to Mars and beyond, the photographs taken during Mercury and Gemini will forever symbolize and document the beginning of humankind’s expansion out into the cosmos.

Ars: I want to understand your process. How many photos did you consider for this book?

Saunders: With Apollo, they took about 35,000 photographs. With Mercury and Gemini, there were about 5,000. Which I was quite relieved about. So yeah, I went through all 5,000 they took. I’m not sure how much 16 millimeter film in terms of time, because it was at various frame rates, but a lot of 16 millimeter film. So I went through every frame of film that was captured from launch to splashdown on every mission.

Ars: Out of that material, how much did you end up processing?

Saunders: What I would first do is have a quick look, particularly if there’s apparently nothing in them, because a lot of them are very underexposed. But with digital processing, like I did with the cover of the Apollo book, we can pull out stuff that you actually can’t see in the raw file. So it’s always worth taking a look. So do a very quick edit, and then if it’s not of interest, it’s discarded. Or it might be that clearly an important moment was happening, even if it’s not a particularly stunning photograph, I would save that one. So I was probably down from 5,000 to maybe 800, and then do a better edit on it.

And then the final 300 that are in the book are those that are either aesthetically stunning, or they’re a big transformation, or they show something important that happened on the mission, or a historically significant moment. But also, what I want to do with the book, as well as showing the photographs, is tell the stories, these incredible human stories that, because of the risks they were taking. So to do that, I effectively reconstructed every mission from launch to splashdown by using lots of different pieces of information in order to effectively map the photography onto a timeline so that it can then tell the story through the captions. So a photograph might be in there simply to help tell part of the story.

Ars: What was your favorite story to tell?

Saunders: Well, perhaps in terms of a chapter and a mission, I’d say Gemini 4 is kind of the heart of the book. You know, first US space walk, quite a lot of drama occurred when they couldn’t close the hatch. There’s some quite poignant shots, particularly of Ed White, of course, who later lost his life in the Apollo 1 fire. But in terms of the story, I mean, Gemini 9A was just, there needs to be a movie about just Gemini 9A. Right from the start, from losing the prime crew, and then just what happened out on Gene Cernan’s EVA, how he got back into the capsule alive is quite incredible, and all this detail I’ve tried to cover because he took his camera. So he called it the spacewalk from hell. Everything that could go wrong went wrong. He was incredibly exhausted, overheated. His visor steamed over. He went effectively blind, and he was at the back of the adapter section. This is at a point when NASA just hadn’t mastered EVA. So, simply how you maneuver in space, they just haven’t mastered, so he was exhausted. He was almost blind. Then he lost communication with Tom Stafford, his command pilot. He tore his suit, because, of course, back then, there were all kinds of jagged parts on the spacecraft.

And then when he’s finally back in the hatch, he was quite a big chap, and they couldn’t close the hatch, so he was bent double trying to close the hatch. He started to see stars. He said, Tom, if we don’t close this hatch now and re-pressurize, I am going to die. They got it closed, got his helmet off, and Tom Stafford said he just looked like someone that had spent far too long in a sauna. Stafford sprayed him with a water hose to kind of cool him down. So what happened on that mission is just quite incredible. But there was something on every mission, you know, from Gus Grissom sinking of the Liberty Bell and him almost drowning, the heat shield coming loose, or an indicator that suggested the heat shield was loose on Glenn’s mission. There’s an image of that in the book. Like I said, I mapped everything to the timeline, and worked out the frame rates, and we’ve got the clock we can see over his shoulder. So I could work out exactly when he was at the point of maximum heating through reentry, when part of the strapping that kept the retro pack on, to try and hold a heat shield on that hit the window, and he’s talking, but no one was listening, because it was during radio blackout.

After being informed his heat shield may have come loose, John Glenn is holding steadfast in the face of real uncertainty, as he observes the retro pack burn up outside his window, illuminating the cabin in an orange glow, during re-entry on February 20, 1962. “This is Friendship Seven. I think the pack just let go … A real fireball outside! … Great chunks of that retro pack breaking off all the way through!” Credit: NASA / Andy Saunders

The process I used for this, on the low-quality 16 mm film, was to stack hundreds and hundreds of frames to bring out incredible detail. You can almost see the pores in his skin. To see this level of detail, to me, it’s just like a portrait of courage. There he is, holding steadfast, not knowing if he’s about to burn up in the atmosphere. So that was quite a haunting image, if you like, to be able to help you step on board, you know, these tiny Mercury spacecraft, to see them, to see what they saw, to look out the windows and see how they saw it.

Ars: What was new or surprising to you as you spent so much time with these photos and looking at the details?

Saunders: The human side to them. Now that we can see them this clearly, they seem to have an emotional depth to them. And it’s that level of risk that they were taking. I think that’s what really hit home. The Earth shots are stunning. You know, you can almost feel the scale, particularly with a super wide lens, and the altitudes they flew to. And you can just imagine what it must have been like out on an EVA, for example. I think Gene Cernan said it was like sitting on God’s front porch, the view he had on his EVA. So those Earth shots are stunning, but it’s really those the human side that really hits home for me. I read every word of every transcript of every mission. All the conversations were recorded on tape between the air and the ground, and between the astronauts when they were out of ground contact, and reading those it really hits home what they were doing. I found myself holding my breath, and, you know, my shoulders were stiff.

Ars: So what’s next? I mean, there’s only about 100 million photos from the Space Shuttle era.

Saunders: Thankfully, they weren’t all taken on film. So if I wanted to complete space on film, then what I haven’t yet done is Apollo-Soyuz, Skylab, and the first, whatever it is, 20 percent of the shuttle. So maybe that’s next. But I would just like a rest, because I’ve been doing this now since the middle of 2019, literally nonstop. It’s all I’ve done with Apollo and now Mercury and Gemini. The books make a really nice set in that they’re exactly the same size. So it covers the first view of the curvature of Earth and space right through to our last steps on the Moon.

Scientists: It’s do or die time for America’s primacy exploring the Solar System

Federal funding is about to run out for 19 active space missions studying Earth’s climate, exploring the Solar System, and probing mysteries of the Universe.

This year’s budget expires at the end of this month, and Congress must act before October 1 to avert a government shutdown. If Congress passes a budget before then, it will most likely be in the form of a continuing resolution, an extension of this year’s funding levels into the first few weeks or months of fiscal year 2026.

The White House’s budget request for fiscal year 2026 calls for a 25 percent cut to NASA’s overall budget, and a nearly 50 percent reduction in funding for the agency’s Science Mission Directorate. These cuts would cut off money for at least 41 missions, including 19 already in space and many more far along in development.

Normally, a president’s budget request isn’t the final say on matters. Lawmakers in the House and Senate have written their own budget bills in the last several months. There are differences between each appropriations bill, but they broadly reject most of the Trump administration’s proposed cuts.

Still, this hasn’t quelled the anxieties of anyone with a professional or layman’s interest in space science. The 19 active robotic missions chosen for cancellation are operating beyond their original design lifetime. However, in many cases, they are in pursuit of scientific data that no other mission has a chance of collecting for decades or longer.

A “tragic capitulation”

Some of the mission names are recognizable to anyone with a passing interest in NASA’s work. They include the agency’s two Orbiting Carbon Observatory missions monitoring data signatures related to climate change, the Chandra X-ray Observatory, which survived a budget scare last year, and two of NASA’s three active satellites orbiting Mars.

And there’s New Horizons, a spacecraft that made front-page headlines in 2015 when it beamed home the first up-close pictures of Pluto. Another mission on the chopping block is Juno, the world’s only spacecraft currently at Jupiter.

Both spacecraft have more to offer, according to the scientists leading the missions.

“New Horizons is perfectly healthy,” said Alan Stern, the mission’s principal investigator at Southwest Research Institute (SWRI). “Everything on the spacecraft is working. All the spacecraft subsystems are performing perfectly, as close to perfectly as one could ever hope. And all the instruments are, too. The spacecraft has the fuel and power to run into the late 2040s or maybe 2050.”

New Horizons is a decade and more than 2.5 billion miles (4.1 billion kilometers) beyond Pluto. The probe flew by a frozen object named Arrokoth on New Year’s Day 2019, returning images of the most distant world ever explored by a spacecraft. Since then, the mission has continued its speedy departure from the Solar System and could become the third spacecraft to return data from interstellar space.

New Horizons cost taxpayers $780 million from the start of development through the end of its primary mission after exploring Pluto. The project received $9.7 million from NASA to cover operations costs in 2024, the most recent year with full budget data.

It’s unlikely New Horizons will be able to make another close flyby of an object like it did with Pluto and Arrokoth. But the science results keep rolling in. Just last year, scientists announced the news that New Horizons found the Kuiper Belt—a vast outer zone of hundreds of thousands of small, icy worlds beyond the orbit of Neptune—might extend much farther out than previously thought.

“We’re waiting for government, in the form of Congress, the administration, to come up with a funding bill for FY26, which will tell us if our mission is on the chopping block or not,” Stern said. “The administration’s proposal is to cancel essentially every extended mission … So, we’re not being singled out, but we would get caught in that.”

Stern, who served as head of NASA’s science division in 2007 and 2008, said the surest way to prevent the White House’s cuts is for Congress to pass a budget with specific instructions for the Trump administration.

“The administration ultimately will make some decision based on what Congress does,” Stern said. “If Congress passes a continuing resolution, then that opens a whole lot of other possibilities where the administration could do something without express direction from Congress. We’re just going to have to see where we end up at the end of September and then in the fall.”

Stern said shutting down so many of NASA’s science missions would be a “tragic capitulation of US leadership” and “fiscally irresponsible.”

“We’re pretty undeniably the frontrunner, and have been for decades, in space sciences,” Stern said. “There’s much more money in overruns than there is in what it costs to run these missions—I mean, dramatically. And yet, by cutting overruns, you don’t affect our leadership position. Turning off spacecraft would put us in third or fourth place, depending on who you talk to, behind the Chinese and the Europeans at least, and maybe behind others.”

Stern resigned his job as NASA’s science chief in 2008 after taking a similar stance arguing against cuts to healthy projects and research grants to cover overruns in other programs, according to a report in Science Magazine.

An unforeseen contribution from Juno

Juno, meanwhile, has been orbiting Jupiter since 2016, collecting information on the giant planet’s internal structure, magnetic field, and atmosphere.

“Everything is functional,” said Scott Bolton, the lead scientist on Juno, also from SWRI. “There’s been some degradation, things that we saw many years ago, but those haven’t changed. Actually, some of them improved, to be honest.”

The only caveat with Juno is some radiation damage to its camera, called JunoCam. Juno orbits Jupiter once every 33 days, and the trajectory brings the spacecraft through intense radiation belts trapped by the planet’s powerful magnetic field. Juno’s primary mission ended in 2021, and it’s now operating in an extended mission approved through the end of this month. The additional time exposed to harsh radiation is, not surprisingly, corrupting JunoCam’s images.

In an interview with Ars, Bolton suggested the radiation issue creates another opportunity for NASA to learn from the Juno mission. Ground teams are attempting to repair the JunoCam imager through annealing, a self-healing process that involves heating the instrument’s electronics and then allowing them to cool. Engineers sparingly tried annealing hardware space, so Juno’s experience could be instructive for future missions.

“Even satellites at Earth experience this [radiation damage], but there’s very little done or known about it,” Bolton said. “In fact, what we’re learning with Juno has benefits for Earth satellites, both commercial and national security.”

Juno’s passages through Jupiter’s harsh radiation belts provide a real-world laboratory to experiment with annealing in space. “We can’t really produce the natural radiation environment at Earth or Jupiter in a lab,” Bolton said.

Lessons learned from Juno could soon be applied to NASA’s next probe traveling to Jupiter. Europa Clipper launched last year and is on course to enter orbit around Jupiter in 2030, when it will begin regular low-altitude flybys of the planet’s icy moon Europa. Before Clipper’s launch, engineers discovered a flaw that could make the spacecraft’s transistors more susceptible to radiation damage. NASA managers decided to proceed with the mission because they determined the damage could be repaired at Jupiter with annealing.

“So, we have rationale to hopefully continue Juno because of science, national security, and it sort of fits in the goals of exploration as well, because you have high radiation even in these translunar orbits [heading to the Moon],” Bolton said. “Learning about how to deal with that and how to build spacecraft better to survive that, and how to repair them, is really an interesting twist that we came by on accident, but nevertheless, turns out to be really important.”

It cost $28.4 million to operate Juno in 2024, compared to NASA’s $1.13 billion investment to build, launch, and fly the spacecraft to Jupiter.

“We’re hoping everything’s going to keep going,” Bolton said. “We put in a proposal for three years. The science is potentially very good. … But it’s sort of unknown. We just are waiting to hear and waiting for direction from NASA, and we’re watching all of the budget scenarios, just like everybody else, in the news.”

NASA headquarters earlier this year asked Stern and Bolton, along with teams leading other science missions coming under the ax, for an outline of what it would take and what it would cost to “close out” their projects. “We sent something that was that was a sketch of what it might look like,” Bolton said.

A “closeout” would be irreversible for at least some of the 19 missions at risk of termination.

“Termination doesn’t just mean shutting down the contract and sending everybody away, but it’s also turning the spacecraft off,” Stern said. “And when you turn off those spacecraft’s radio receivers, there’s no way to turn them back on because they’re off. They can never get a command in.

“So, if we change our mind, we’ve had another election, or had some congressional action, anything like that, it’s really terminating the spacecraft, and there’s no going back.”

NASA found intriguing rocks on Mars, so where does that leave Mars Sample Return?

Mars Sample Return, NASA, Sean Duffy, Space / Mike M. / September 13, 2025

NASA’s interim administrator, Sean Duffy, was fired up on Wednesday when he joined a teleconference to talk about new scientific findings that concerned the potential for life to have once existed on Mars.

“This is exciting news,” said Duffy about an arrow-shaped rock on Mars found by NASA’s Perseverance rover. The rock contained chemical signatures and structures that could have been formed by ancient microbial life. The findings were intriguing, but not conclusive. Further study of the rocks in an advanced lab on Earth might prove more definitive.

Duffy was ready, he said, to discuss the scientific results along with NASA experts on the call with reporters. However, the very first question—and for any space reporter, the obvious one—concerned NASA’s on-again, off-again plan to return rocks from the surface of Mars for study on Earth. This mission, called Mars Sample Return, has been on hold for nearly two years after an independent analysis found that NASA’s bloated plan would cost at least $8 billion to $11 billion. President Trump has sought to cancel it outright.

Duffy faces the space press

“What’s the latest on NASA’s plans to retrieve the samples from Perseverance?” asked Marcia Dunn, a reporter with the Associated Press, about small vials of rocks collected by the NASA rover on Mars.

“So listen, we’re looking at how we get this sample back, or other samples back,” Duffy replied. “What we’re going to do is look at our budget, so we look at our timing, and you know, how do we spend money better? And you know, what technology do we have to get samples back more quickly? And so that’s a current analysis that’s happening right now.”

A couple of questions later, Ken Chang, a science reporter with The New York Times, asked Duffy why President Trump’s budget request called for the cancellation of Mars Sample Return and whether that was still the president’s intent.

“I want to be really clear,” Duffy replied. “This is a 30-year process that NASA has undertaken. President Trump didn’t say, ‘Hey, let’s forget about Mars.’ No, we’re continuing our exploration. And by the way, we’ve been very clear under this president that we don’t want to just bring samples back from Mars. We want to send our boots to the Moon and to Mars, and that is the work that we’re doing. Amit (Kshatriya, the new associate administrator of NASA) even said maybe we’ll send our equipment to test this sample to Mars itself. All options are on the table.”

Welcome to Edition 8.10 of the Rocket Report! Dear readers, if everything goes according to plan, four astronauts are less than six months away from traveling around the far side of the Moon and breaking free of low-Earth orbit for the first time in more than 53 years. Yes, there are good reasons to question NASA’s long-term plans for the Artemis lunar program—the woeful cost of the Space Launch System rocket, the complexity of new commercial landers, and a bleak budget outlook. But many of us who were born after the Apollo Moon landings have been waiting for this moment our whole lives. It is almost upon us.

As always, we welcome reader submissions. If you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.

North Korea fires solid rocket motor. North Korea said Tuesday it had conducted the final ground test of a solid-fuel rocket engine for a long-range ballistic missile in its latest advancement toward having an arsenal that could viably threaten the continental United States, the Associated Press reports. The test Monday observed by leader Kim Jong Un was the ninth of the solid rocket motor built with carbon fiber and capable of producing 1,971 kilonewtons (443,000 pounds) of thrust, more powerful than past models, according to the North’s official Korean Central News Agency.

Mobility and flexibility … Solid-fueled intercontinental ballistic missiles, or ICBMs, have advantages over liquid-fueled missiles, which have historically comprised the bulk of North Korea’s inventory. Solid rocket motors can be stored for longer periods of time and are easier to conceal, transport, and launch on demand. The new solid rocket motor will be used on a missile called the Hwasong-20, according to North Korean state media. The AP reports some analysts say North Korea may conduct another ICBM test around the end of the year, showcasing its military strength ahead of a major ruling party congress expected in early 2026.

Astrobotic eyes Andøya. US-based lunar logistics company Astrobotic and Norwegian spaceport operator Andøya Space have signed a term sheet outlining the framework for a Launch Site Agreement, European Spaceflight reports. The agreement, once finalized, will facilitate flights of Astrobotic’s Xodiac lander testbed from the Andøya Space facilities. The Xodiac vertical takeoff, vertical landing rocket was initially developed by Masten Space Systems to simulate landing on the Moon and Mars. When Masten filed for bankruptcy in 2022, Astrobotic acquired its intellectual property and assets, including the Xodiac vehicle.

Across the pond … So far, the small Xodiac rocket has flown on low-altitude atmospheric hops from Mojave, California, reaching altitudes of up to 500 meters, or 1,640 feet. The agreement between Astrobotic and Andøya paves the way for “several” Xodiac flight campaigns from Andøya Space facilities on the Norwegian coast. “Xodiac’s presence at Andøya represents a meaningful step toward delivering reliable, rapid, and cost-effective testing and demonstration capabilities to the European space market,” said Astrobotic CEO John Thornton.

Ursa Major breaks ground in Colorado. Ursa Major on Wednesday said it has broken ground on a new 400-acre site where it will test and qualify large-scale solid rocket motors for current and future missiles, including the Navy’s Standard Missile fleet, Defense Daily reports. The new site in Weld County, Colorado, north of Denver, will be ready for testing to begin in the fourth quarter of 2025. Ursa Major will be able to conduct full-scale static firings, and drop and temperature storage testing for current and future missile systems.

Seeking SRM options … Ursa Major said the new facility will support national and missile defense programs. The company’s portfolio includes solid rocket motors (SRMs) ranging from 2 inches to 22 inches in diameter for missiles like the Stinger, Javelin, and air-defense interceptors. Ursa Major aims to join industry incumbents Northrop Grumman, L3Harris, and newcomer Anduril as a major supplier of SRMs to the government. “This facility represents a major step forward in our ability to deliver qualified SRMs that are scalable, flexible, and ready to meet the evolving threat environment,” said Dan Jablonsky, CEO of Ursa Major, in a statement. “It’s a clear demonstration of our commitment and ability to rapidly advance and expand the American-made solid rocket motor industrial base that the country needs, ensuring warfighters will have the quality and quantity of SRMs needed to meet mission demands.”

Falcon 9 launches first satellites in a military megaconstellation. The first 21 satellites in a constellation that could become a cornerstone for the Pentagon’s Golden Dome missile-defense shield successfully launched from California Wednesday aboard a SpaceX Falcon 9 rocket, Ars reports. The Falcon 9 took off from Vandenberg Space Force Base, California, and headed south over the Pacific Ocean, reaching an orbit over the poles before releasing the 21 military-owned satellites to begin several weeks of activations and checkouts.

First of many … These 21 satellites will boost themselves to a final orbit at an altitude of roughly 600 miles (1,000 kilometers). The Pentagon plans to launch 133 more satellites over the next nine months to complete the build-out of the Space Development Agency’s first-generation, or Tranche 1, constellation of missile-tracking and data-relay satellites. Military officials have worked for six years to reach this moment. The Space Development Agency (SDA) was established during the first Trump administration, which made plans for an initial set of demonstration satellites that launched a couple of years ago. In 2022, the Pentagon awarded contracts for the first 154 operational spacecraft, including the ones launched Wednesday. “Back in 2019, when the SDA was stood up, it was to do two things. One was to make sure that we can do beyond line of sight targeting, and the other was to pace the threat, the emerging threat, in the missile-warning and missile-tracking domain. That’s what the focus has been,” said Gurpartap “GP” Sandhoo, the SDA’s acting director.

Another Falcon 9 was delayed three times. SpaceX scrubbed launching a communications satellite from an Indonesian company for a third consecutive day Wednesday, Spaceflight Now reports. Possible technical issues got in the way of a launch attempt Wednesday evening after back-to-back days of weather delays at Cape Canaveral Space Force Station, Florida. The Falcon 9 finally launched Thursday evening with the Boeing-built Nusantara Lima communications satellite, targeting a geosynchronous transfer orbit. It’s the latest satellite from the Indonesian company Pasifik Satelit Nusantara.

A declining market … This was just the fifth geosynchronous communications satellite to launch on a commercial rocket this year, all by SpaceX. There were 21 such satellites that launched on commercial vehicles in 2015, including SpaceX’s Falcon 9, Europe’s Ariane 5, Russia’s Proton, ULA’s Atlas V, and Japan’s H-IIA. Much of the world’s launch capacity today is used to deploy smaller communications satellites into low-Earth orbit, primarily for broadband connectivity rather than for the video broadcast market once dominated by higher-altitude geosynchronous satellites.

Putin urges Russia to build more rocket engines. Russian President Vladimir Putin urged aerospace industry leaders on September 5 to press on with efforts to develop booster rocket engines for space launch vehicles and build on Russia’s longstanding reputation as a leader in space technology, Reuters reports. Putin, who spent the preceding days in China and the Russian far eastern port of Vladivostok, flew to the southern Russian city of Samara, where he met industry specialists and toured the Kuznetsov design bureau engine manufacturing plant.

A shell of its former self … “It is important to consistently renew production capacity in terms of engines for booster rockets,” Russian news agencies quoted Putin as saying during the visit. “And in doing so, we must not only meet our own current and future needs but also move actively on world markets and be successful competitors.” The Kuznetsov plant in Samara builds medium-class RD-107 and RD-108 engines for Russia’s Soyuz-2 rockets, which launch Russian military satellites and crew and cargo to the International Space Station. Their designs can be traced to the dawn of the Space Age nearly 70 years ago. Meanwhile, the outlook for heavier-duty Russian rocket engines is murky, at best. Russia’s most-flown large rocket engine in the post-Cold War era, the RD-180, produced by a company called Energomash, is out of production after the end of sales to the United States.

India nabs a noteworthy launch contract. Astroscale, a satellite servicing and space debris mitigation company based in Japan, has selected India’s Polar Satellite Launch Vehicle (PSLV) to deliver a small satellite named ISSA-J1 to orbit in 2027. This is an interesting mission. The ISSA-J1 spacecraft will fly up to two large pieces of satellite debris in orbit to image and inspect them. ISSA-J1, developed in partnership with the Japanese government, is one in a series of Astroscale missions testing different ways of approaching, monitoring, capturing, and refueling other objects in space. The launch agreement was signed between Astroscale and NewSpace India Limited, the commercial arm of India’s space agency.

Rideshare not an option … “We selected NSIL after thorough evaluations of more than 10 launch service providers over the past year, considering technical capabilities, track record, cost, and other elements,” said Eddie Kato, president and managing director of Astroscale Japan. India’s PSLV is right-sized for a mission like this. ISSA-J1 is a rarity in that it must launch on a dedicated rocket because it has to reach a specific orbit to line up with the pieces of space debris it will approach and inspect. Rideshare launches, such as those that routinely fly on SpaceX’s Falcon 9 rocket, are cheaper but go to standard orbits popular for many different types of satellite missions. A dedicated launch on a Falcon 9 would presumably have been more expensive than a flight on India’s smaller PSLV. Rocket Lab’s Electron, another rocket popular for dedicated launches of small satellites, lacks the performance required for Astroscale’s mission.

Russian cargo en route to ISS. Another cargo ship is flying to humanity’s orbital outpost with the successful launch of Russia’s Progress MS-32 supply freighter Thursday from the Baikonur Cosmodrome in Kazakhstan, NASASpaceflight.com reports. The supply ship launched aboard a Soyuz-2.1a rocket and arrived in orbit about nine minutes later, kicking off a two-day pursuit of the International Space Station. This was the 300th launch of an assembly, crew, or cargo mission to the ISS since 1998, including a handful of missions that didn’t reach the complex due to rocket or spacecraft failures.

Important stuff … The Progress MS-32 cargo craft will dock with the aft port of the space station’s Russian Zvezda service module Saturday. The payloads flying on the Progress mission include food, experiments, clothing, water, air, and propellant to be pumped into the space station’s onboard tanks. The spacecraft will also reboost the lab’s orbit.

Metallic tiles? Not so great. It has been two weeks since SpaceX’s last Starship test flight, and engineers have diagnosed issues with its heat shield, identified improvements, and developed a preliminary plan for the next time the ship heads into space, Ars reports. Bill Gerstenmaier, a SpaceX executive in charge of build and flight reliability, presented the findings Monday at the American Astronautical Society’s Glenn Space Technology Symposium in Cleveland. The test flight went “extremely well,” Gerstenmaier said, but he noted some important lessons learned with the ship’s heat shield.

Crunch wrap reigns supreme … “We were essentially doing a test to see if we could get by with non-ceramic tiles, so we put three metal tiles on the side of the ship to see if they would provide adequate heat control, because they would be simpler to manufacture and more durable than the ceramic tiles. It turns out they’re not,” Gerstenmaier said. “The metal tiles… didn’t work so well.” One bright spot with the heat shield was the performance of a new experimental material around and under the tiles. “We call it crunch wrap,” Gerstenmaier said. “It’s like a wrapping paper that goes around each tile.” On the next Starship flight, SpaceX will likely cover more parts of the heat shield with this crunch wrap material. Gerstenmaier said the inaugural flight of Starship Version 3, with upgraded engines and more fuel, is now set to occur next year.

An SLS compromise might be afoot in DC. The Trump administration is seeking to cancel NASA’s Space Launch System rocket after two more flights, but key lawmakers in Congress, including Republican Sen. Ted Cruz of Texas, aren’t ready to go along. So is this an impasse? Possibly not, as sources say the White House and Congress may not be all that far apart on how to handle this. The solution involves canceling part of the SLS rocket now, but not all of it, Ars reports.

Goodbye EUS? … The compromise might be to cancel a large new upper stage for the SLS rocket called the Exploration Upper Stage. This would save NASA billions of dollars, and the agency could instead procure commercial upper stages, such as those built by United Launch Alliance or Blue Origin, to fly on SLS rockets after NASA’s Artemis III mission. It would also eliminate the need for NASA to finish building an expensive new launch tower at Kennedy Space Center, Florida. The upper stage flying on the first three SLS missions is no longer in production. Sources indicated to Ars that Blue Origin has already begun work on a modified version of its New Glenn upper stage that could fit within the shroud of the SLS rocket.

Pentagon begins deploying new satellite network to link sensors with shooters

The first 21 satellites in a constellation that could become a cornerstone for the Pentagon’s Golden Dome missile-defense shield successfully launched from California Wednesday aboard a SpaceX Falcon 9 rocket.

The Falcon 9 took off from Vandenberg Space Force Base, California, at 7: 12 am PDT (10: 12 am EDT; 14: 12 UTC) and headed south over the Pacific Ocean, heading for an orbit over the poles before releasing the 21 military-owned satellites to begin several weeks of activations and checkouts.

These 21 satellites will boost themselves to a final orbit at an altitude of roughly 600 miles (1,000 kilometers). The Pentagon plans to launch 133 more satellites over the next nine months to complete the build-out of the Space Development Agency’s first-generation, or Tranche 1, constellation of missile-tracking and data-relay satellites.

“We had a great launch today for the Space Development Agency, putting this array of space vehicles into orbit in support of their revolutionary new architecture,” said Col. Ryan Hiserote, system program director for the Space Force’s assured access to space launch execution division.

Over the horizon

Military officials have worked for six years to reach this moment. The Space Development Agency (SDA) was established during the first Trump administration, which made plans for an initial set of demonstration satellites that launched a couple of years ago. In 2022, the Pentagon awarded contracts for the first 154 operational spacecraft. The first batch of 21 data-relay satellites built by Colorado-based York Space Systems is what went up Wednesday.

“Back in 2019, when the SDA was stood up, it was to do two things. One was to make sure that we can do beyond line of sight targeting, and the other was to pace the threat, the emerging threat, in the missile-warning and missile-tracking domain. That’s what the focus has been,” said Gurpartap “GP” Sandhoo, the SDA’s acting director.

Historically, the military communications and missile-warning networks have used a handful of large, expensive satellites in geosynchronous orbit some 22,000 miles (36,000 kilometers) above the Earth. This architecture was devised during the Cold War and is optimized for nuclear conflict and intercontinental ballistic missiles.

For example, the military’s ultra-hardened Advanced Extremely High Frequency satellites in geosynchronous orbit are designed to operate through an electromagnetic pulse and nuclear scintillation. The Space Force’s missile-warning satellites are also in geosynchronous orbit, with infrared sensors tuned to detect the heat plume of a missile launch.

The problem? Those satellites cost more than $1 billion a pop. They’re also vulnerable to attack from a foreign adversary. Pentagon officials say the SDA’s satellite constellation, officially called the Proliferated Warfighter Space Architecture, is tailored to detect and track more modern threats, such as smaller missiles and hypersonic weapons carrying conventional warheads. It’s easier for these missiles to evade the eyes of older early warning satellites.

What’s more, the SDA’s fleet in low-Earth orbit will have numerous satellites. Losing one or several satellites to an attack would not degrade the constellation’s overall capability. The SDA’s new relay satellites cost between $14 and $15 million each, according to Sandhoo. The total cost of the first tranche of 154 operational satellites totals approximately $3.1 billion.

Multi-mission satellites

These satellites will not only detect and track ballistic and hypersonic missile launches; they will also transmit signals between US forces using an existing encrypted tactical data link network known as Link 16. This UHF system is used by NATO and other US allies to allow military aircraft, ships, and land forces to share tactical information through text messages, pictures, data, and voice communication in near real time, according to the SDA’s website.

Up to now, Link 16 radios were ubiquitous on fighter jets, helicopters, naval vessels, and missile batteries. But they had a severe limitation. Link 16 was only able to close a radio link with a clear line of sight. The Space Development Agency’s satellites will change that, providing direct-to-weapon connectivity from sensors to shooters on Earth’s surface, in the air, and in space.

The relay satellites, which the SDA calls the transport layer, are also equipped with Ka-band and laser communication terminals for higher-bandwidth connectivity.

“What the transport layer does is it extends beyond the line of sight,” Sandhoo said. “Now, you’re able to talk not only to within a couple of miles with your Link 16 radios, (but) we can use space to, let’s say, go from Hawaii out to Guam using those tactical radios, using a space layer.”

The Space Development Agency’s “Tranche 1” architecture includes 154 operational satellites, 126 for data relay and 28 for missile tracking. With this illustration, the SDA does its best to show how the complex architecture is supposed to work. Credit: Space Development Agency

Another batch of SDA relay satellites will launch next month, and more will head to space in November. In all, it will take 10 launches to fully deploy the SDA’s Tranche 1 constellation. Six of those missions will carry data-relay satellites, and four will carry satellites with sensors to detect and track missile launches. The Pentagon selected several contractors to build the satellites, so the military is not reliant on a single company. The builders of the SDA’s operational satellites include York, Lockheed Martin, Northrop Grumman, and L3Harris.

“We will increase coverage as we get the rest of those launches on orbit,” said Michael Eppolito, the SDA’s acting deputy director.

The satellites will connect with one another using inter-satellite laser links, creating a mesh network with sufficient range to provide regional communications, missile warning, and targeting coverage over the Western Pacific beginning in 2027. US Indo-Pacific Command, which oversees military operations in this region, is slated to become the first combatant command to take up use of the SDA’s satellite constellation.

This is not incidental. US officials see China as the nation’s primary strategic threat, and Indo-Pacific Command would be on the front lines of any future conflict between Chinese and US forces. The SDA has contracts in place for more than 270 second-generation, or Tranche 2, satellites, to further expand the network’s reach. There’s also a third generation in the works, but the Pentagon has paused part of the SDA’s Tranche 3 program to evaluate other architectures, including one offered by SpaceX.

Teaching tactical operators to use the new capabilities offered by the SDA’s satellite fleet could be just as challenging as building the network itself. To do this, the Pentagon plans to put soldiers, sailors, airmen, and marines through “warfighter immersion” training beginning next year. This training will allow US forces to “get used to using space from this construct,” Sandhoo said.

“This is different than how it has been done in the past,” Sandhoo said. “This is the first time we’ll have a space layer actually fully integrated into our warfighting operations.”

The SDA’s satellite architecture is a harbinger for what’s to come with the Pentagon’s Golden Dome system, a missile-defense shield for the US homeland proposed by President Donald Trump in an executive order in January. Congress authorized a down payment on Golden Dome in July, the first piece of funding for what the White House says will cost $175 billion over the next three years.

Golden Dome, as currently envisioned, will require thousands of satellites in low-Earth orbit to track missile launches and space-based interceptors to attempt to shoot them down. The Trump administration hasn’t said how much of the shield might be deployed by the end of 2028, or what the entire system might eventually cost.

But the capabilities of the SDA’s satellites will lay the foundation for any regional or national missile-defense shield. Therefore, it seems likely that the military will incorporate the SDA network into Golden Dome, which, at least at first, is likely to consist of technologies already in space or nearing launch. Apart from the Space Development Agency’s architecture in low-Earth orbit (LEO), the Space Force was already developing a new generation of missile-warning satellites to replace aging platforms in geosynchronous orbit (GEO), plus a fleet of missile-warning satellites to fly at a midrange altitude between LEO and GEO.

Air Force Gen. Gregory Guillot, commander of US Northern Command, said in April that Golden Dome “for the first time integrates multiple layers into one system that allows us to detect, track, and defeat multiple types of threats that affect us in different domains.

“So, while a lot of the components and the requirements were there in the past, this is the first time that it’s all tied together in one system,” he said.

Congress and Trump may compromise on the SLS rocket by axing its costly upper stage

exploration upper stage, NASA, sls, Space, Trump / DJ Henderson / September 8, 2025

There are myriad questions about how NASA’s budget process will play out in the coming weeks, with the start of the new fiscal year on October 1 looming.

For example, the Trump administration may seek to shut off dozens of science missions that are either already in space or in development. Although Congress has signaled a desire to keep these missions active, absent a confirmed budget, the White House has made plans to turn off the lights.

Some answers may be forthcoming this week, as the House Appropriations Committee will take up the Commerce, Justice, and Science budget bill on Wednesday morning. However great uncertainty remains about whether there will be a budget passed by October 1 (unlikely), a continuing resolution, or a government shutdown.

Behind the scenes, discussions are also taking place about NASA’s Artemis Program in general and the future of the Space Launch System rocket specifically.

$4 billion a launch is too much

From the beginning, the second Trump administration has sought to cancel the costly, expendable rocket. Some officials wanted to end the rocket immediately, but eventually the White House decided to push for cancellation after Artemis III. This seemed prudent because it allowed the United States the best possible chance to land humans back on the Moon before China got there, and then transition to a more affordable lunar program as quickly as possible.

Congress, particularly US Sen. Ted. Cruz, R-Texas, was not amenable. And so, in supplemental funding as part of the “One Big Beautiful Bill,” Cruz locked in billions of dollars to ensure that Artemis IV and Artemis V flew on the SLS rocket, with the promise of additional missions.

Since the release of its budget proposal in May, which called for an end to the SLS rocket after Artemis III, the White House has largely been silent, offering no response to Congress. However that changed last week, when interim NASA Administrator Sean Duffy addressed the issue on a podcast hosted by one of the agency’s public relations officials, Gary Jordan:

GOP may finally succeed in unrelenting quest to kill two NASA climate satellites

climate change, Donald Trump, Earth science, greenhouse gases, NASA, nasa budget, orbiting carbon observatory, Science, Space, space policy / DJ Henderson / September 6, 2025

Before satellite measurements, researchers relied on estimates and data from a smattering of air and ground-based sensors. An instrument on Mauna Loa, Hawaii, with the longest record of direct carbon dioxide measurements, is also slated for shutdown under Trump’s budget.

It requires a sustained, consistent dataset to recognize trends. That’s why, for example, the US government has funded a series of Landsat satellites since 1972 to create an uninterrupted data catalog illustrating changes in global land use.

But NASA is now poised to shut off OCO-2 and OCO-3 instead of thinking about how to replace them when they inevitably cease working. The missions are now operating beyond their original design lives, but scientists say both instruments are in good health.

Can anyone replace NASA?

Research institutes in Japan, China, and Europe have launched their own greenhouse gas-monitoring satellites. So far, all of them lack the spatial resolution of the OCO instruments, meaning they can’t identify emission sources with the same precision as the US missions. A new European mission called CO2M will come closest to replicating OCO-2 and OCO-3, but it won’t launch until 2027.

Several private groups have launched their own satellites to measure atmospheric chemicals, but these have primarily focused on detecting localized methane emissions for regulatory purposes, and not on global trends.

One of the newer groups in this sector, known as the Carbon Mapper Coalition, launched its first small satellite last year. This nonprofit consortium includes contributors from JPL, the same lab that spawned the OCO instruments, as well as Planet Labs, the California Air Resources Board, universities, and private investment funds.

Government leaders in Montgomery County, Maryland, have set a goal of reducing greenhouse gas emissions by 80 percent by 2027, and 100 percent by 2035. Mark Elrich, the Democratic county executive, said the pending termination of NASA’s carbon-monitoring missions “weakens our ability to hold polluters accountable.”

“This decision would … wipe out years of research that helps us understand greenhouse gas emissions, plant health, and the forces that are driving climate change,” Elrich said in a press conference last month.

NASA’s acting chief “angry” about talk that China will beat US back to the Moon

administrator, artemis, china, NASA, orion, Sean Duffy, sls, Space, startship / DJ Henderson / September 6, 2025

NASA’s interim administrator, Sean Duffy, said Thursday he has heard the recent talk about how some people are starting to believe that China will land humans on the Moon before NASA can return there with the Artemis Program.

“We had testimony that said NASA will not beat China to the Moon,” Duffy remarked during an all-hands meeting with NASA employees. “That was shade thrown on all of NASA. I heard it, and I gotta tell you what, maybe I am competitive, I was angry about it. I can tell you what, I’ll be damned if that is the story that we write. We are going to beat the Chinese to the Moon.”

Duffy’s remarks followed a Congressional hearing on Wednesday during which former Congressman Jim Bridenstine, who served as NASA administrator during President Trump’s first term, said China had pulled ahead of NASA and the United States in the second space race.

“Unless something changes, it is highly unlikely the United States will beat China’s projected timeline to the Moon’s surface,” said Bridenstine, who led the creation of the Artemis Program in 2019. China has said multiple times that it intends to land taikonuats on the Moon before the year 2030.

A lot of TV appearances

Duffy’s remarks were characteristic of his tenure since his appointment two months ago by Trump to serve as interim administrator of the space agency. He has made frequent appearances on Fox News and offered generally upbeat views of NASA’s position in its competition with China for supremacy in space. And on Friday, in a slickly produced video, he said, “I’m committed to getting us back to the Moon before President Trump leaves office.”

Sources have said Duffy, already a cabinet member as the secretary of transportation, is also angling to remove the “interim” from his NASA administrator title. Like Bridenstine, he has a capable political background and politics that align with the Trump administration. He is an excellent public speaker and knows the value of speaking to the president through Fox News. To date, however, he has shown limited recognition of the reality of the current competition with China.

All the news that’s fit to lift

“Nobody’s waving the white flag here until the last hour of the last day.”

Welcome to Edition 8.09 of the Rocket Report! The biggest news of the week happened inside the Beltway rather than on a launch pad somewhere. In Washington, DC, Congress has pushed back on the Trump administration’s plan to stop flying the Space Launch System rocket after Artemis III. Congress made it clear that it wants to keep the booster in business for a long time. The big question now is whether the Trump White House will blink.

As always, we welcome reader submissions, and if you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

Israel launches SAR satellite. The Israel Ministry of Defense, Israel Defense Forces, and Israel Aerospace Industries successfully launched the Ofek 19 satellite on Tuesday from the Palmachim Airbase. The launch was carried out by the country’s solid-propellant Shavit 2 rocket. Ofek 19 is a synthetic aperture radar observation satellite with enhanced capabilities, 7 Israel National News reports.

A unique launch posture … This was the seventh launch of the Shavit-2 vehicle, which made its debut in June 2007. The most recent launch prior to this week occurred in March 2023. Because of its geographic location and difficult relations with surrounding countries, Israel launches its rockets to the west, over the Mediterranean Sea. (submitted by MarkW98)

Canadian launch firm invests in launch site. Earlier this summer, Reaction Dynamics, an Ontario-based launch company, closed on a Series A funding round worth $10 million. This will support the next phase of development of the Canadian company’s hybrid propulsion system, of which an initial suborbital demonstration flight is planned for this winter. Now the company has taken some of this funding and invested in a launch site in Nova Scotia, SpaceQ reports.

Getting in on the ground floor … In a transaction worth $1.2 million, Reaction Dynamics is investing in Maritime Launch Services, which is developing the Spaceport Nova Scotia facility. Reaction Dynamics intends to launch its Aurora-8 rocket from the Canadian launch site. Bachar Elzein, the CEO of Reaction Dynamics, said the move made sense for two reasons. The first is that it secures “a spot to launch our very first orbital rocket,” with Elzein adding, “we believe in their vision,” and thus wanted to invest. That second factor had to do with all the work, the heavy lifting, MLS has done to date, to build a spaceport from the ground up. (submitted by JoeyS)

MaiaSpace completes tank tests. French rocket builder and ArianeGroup subsidiary MaiaSpace announced the completion of a monthslong test campaign that subjected several subscale prototypes of its propellant tanks to high-pressure burst tests, European Spaceflight reports. Over the course of six months, the company conducted 15 “burst” tests of subscale propellant tanks. Burst tests push tanks to failure to assess their structural limits and ensure they can safely withstand pressures well beyond normal operating conditions.

Working toward space … The data collected will be used to validate mechanical models that will inform the final design of the full-scale propellant tanks. The tests come as MaiaSpace continues to work toward the debut flight of its Maia rocket, which could take place in 2027 from French Guiana. At present, the company intends the rocket to have a lift capacity of 1.5 metric tons to low-Earth orbit.

Orienspace secures B+ round funding. Chinese commercial rocket company Orienspace has raised tens of millions of dollars in Series B+ financing as it moves towards a key test flight, Space News reports. Orienspace secured funding of between $27 million and $124 million, according to the Chinese-language Taibo Network. The capital will be used mainly for the follow-up development and mass production of the Gravity-2 medium-lift liquid launch vehicle.

Not a small rocket … The company will soon begin comprehensive ground verification tests for the Gravity-2 and is scheduled to carry out its first flight test by the end of this year. In July, Orienspace successfully conducted a hot fire test of a Gravity-2 kerosene-liquid oxygen first-stage engine, including gimbal and valve system evaluations. Gravity-2 is expected to lift on the order of 20 metric tons to low-Earth orbit.

Rocket Lab unveils Neutron launch complex. As Rocket Lab prepares to roll out its new Neutron, the firm recently unveiled the launch complex from which the vehicle will fly, DefenseNews reports. Located within the Virginia Space Authority’s Mid-Atlantic Regional Spaceport in Wallops Island, the facility, dubbed Launch Complex 3, will support testing, launch, and return missions for the reusable rocket. Rocket Lab sees Neutron as a contender to help ease the bottleneck in demand from both commercial and military customers for a ride to space. Today, that demand is largely being met by a single provider in the medium-lift market, SpaceX.

A launch this year? … It sounds unlikely. During the event, Rocket Lab founder Peter Beck said that although he believes the company’s plan to launch this year is within reach, the schedule is aggressive with no margin for error. Speaking with reporters at the launch site, Beck said the company has some key testing in the coming months to qualify key stages of the rocket, which will give it a better idea of whether it can meet that 2025 timeline. “Nobody’s waving the white flag here until the last hour of the last day,” he said. This one is unlikely to break Berger’s Law, however.

SpaceX obtains approval to ramp up Falcon 9 cadence. The Federal Aviation Administration issued a record of decision on Wednesday approving SpaceX’s plan to more than double the number of Falcon 9 launches from Space Launch Complex-40 (SLC-40), the busiest of the company’s four operational launch pads. The FAA concluded that the proposed launch rate “would not significantly impact the quality of the human environment,” Ars reports.

Reaching ludicrous speed … The environmental review paves the way for SpaceX to launch up to 120 Falcon 9 rockets per year from SLC-40, an increase from 50 launches covered in a previous FAA review in 2020. Since then, the FAA has issued SpaceX temporary approval to go beyond 50 launches from SLC-40. For example, SpaceX launched 62 of its overall 132 Falcon 9 flights last year from SLC-40. SpaceX’s goal for this year is 170 Falcon 9 launches, and the company is on pace to come close to this target.

NASA sets date for science mission. NASA said Thursday that a trio of spacecraft to study the Sun will launch no earlier than September 23, on a Falcon 9 rocket. The missions include NASA’s IMAP (Interstellar Mapping and Acceleration Probe), NASA’s Carruthers Geocorona Observatory, and NOAA’s SWFO-L1 (Space Weather Follow On-Lagrange 1) spacecraft. After launching from Kennedy Space Center, the spacecraft will travel together to their destination at the first Earth-Sun Lagrange point (L1), around 1 million miles from Earth toward the Sun.

Fun in the Sun … The missions will each focus on different effects of the solar wind and space weather, from their origins at the Sun to their farthest reaches billions of miles away at the edge of our Solar System. Research and observations from the missions will help us better understand the Sun’s influence on Earth’s habitability, map our home in space, and protect satellites and voyaging astronauts and airline crews from space weather impacts.

Starship’s heat shield shows promise. One of the key issues ahead of last week’s test of SpaceX’s Starship vehicle was the performance of the upper stage heat shield, Ars reports. When the vehicle landed in the Indian Ocean, it had a decidedly orange tint. So what gives? SpaceX founder Elon Musk provided some clarity after the flight, saying, “Worth noting that the heat shield tiles almost entirely stayed attached, so the latest upgrades are looking good! The red color is from some metallic test tiles that oxidized and the white is from insulation of areas where we deliberately removed tiles.”

A step toward the goal … The successful test and additional information from Musk suggest that SpaceX is making progress on developing a heat shield for Starship. This really is the key technology to make an upper stage rapidly reusable—NASA’s space shuttle orbiters were reusable but required a standing army to refurbish the vehicle between flights. To unlock Starship’s potential, SpaceX wants to be able to refly Starships within 24 hours.

Ted Cruz emerges as key SLS defender. All of the original US senators who created and sustained NASA’s Space Launch System rocket over the last 15 years—Bill Nelson, Kay Bailey Hutchison, and Richard Shelby—have either retired or failed to win reelection. However, Ars reports that a new champion has emerged to continue the fight: Texas Republican Ted Cruz. As part of its fiscal year 2026 budget, the White House sought to end funding for the Space Launch System rocket after the Artemis III mission, and also cancel the Lunar Gateway, an orbital space station that provides a destination for the rocket.

Money for future missions … However, Cruz subsequently crafted a NASA provision tacked onto President Trump’s “One Big, Beautiful Bill.” The Cruz addendum provided $6.7 billion in funding for two additional SLS missions, Artemis IV and Artemis V, and to continue Gateway construction. In several hearings this year, Cruz has made it clear that his priorities for human spaceflight are to beat China back to the Moon and maintain a presence there. However, it is now increasingly clear that he views this as only being possible through continued use of NASA’s SLS rocket.

SpaceX seeks to solve Starship prop demands. If SpaceX is going to fly Starships as often as it wants to, it’s going to take more than rockets and launch pads. Tanker trucks have traditionally delivered rocket propellant to launch pads at America’s busiest spaceports in Florida and California. SpaceX has used the same method of bringing propellant for the first several years of operations at Starbase. But a reusable Starship’s scale dwarfs that of other rockets. It stands more than 400 feet tall, with a capacity for more than a million gallons of super-cold liquid methane and liquid oxygen propellants.

That’s a lot of gas … SpaceX also uses large quantities of liquid nitrogen to chill and purge the propellant loading system for Starship. It takes more than 200 tanker trucks traveling from distant refineries to deliver all of the methane, liquid oxygen, and liquid nitrogen for a Starship launch. SpaceX officials recognize this is not an efficient means of conveying these commodities to the launch pad. It takes time, emits pollution, and clogs roadways. SpaceX’s solution to some of these problems is to build its own plants to generate cryogenic fluids. In a new report, Ars explains how the company plans to do this.

SpaceX’s goal for this year is 170 Falcon 9 launches, and the company is on pace to come close to this target. Most Falcon 9 launches carry SpaceX’s own Starlink broadband satellites into orbit. The FAA’s environmental approval opens the door for more flights from SpaceX’s busiest launch pad.

But launch pad availability is not the only hurdle limiting how many Falcon 9 flights can take off in a year. There’s also the rate of production for Falcon 9 upper stages, which are new on each flight, and the time it takes for each vessel in SpaceX’s fleet of drone ships (one in California, two in Florida) to return to port with a recovered booster and redeploy back to sea again for the next mission. SpaceX lands Falcon 9 boosters on offshore drone ships after most of its launches and only brings the rocket back to an onshore landing on missions carrying lighter payloads to orbit.

When a Falcon 9 booster does return to landing on land, it targets one of SpaceX’s recovery zones at military-run spaceports in Florida and California. SpaceX’s landing zone at Vandenberg Space Force Base in California is close to the Falcon 9 launch pad there.

The Space Force wants SpaceX, and potentially other future reusable rocket companies, to replicate the side-by-side launch and landing pads at Cape Canaveral.

To do that, the FAA also gave the green light Wednesday for SpaceX to construct and operate a new rocket landing zone at SLC-40 and conduct up to 34 first-stage booster landings there each year. The landing zone will consist of a 280-foot diameter concrete pad surrounded by a 60-foot-wide gravel apron. The landing zone’s broadest diameter, including the apron, will measure 400 feet.

SpaceX is in an earlier phase of planning for a Falcon landing pad at historic Launch Complex-39A at NASA’s Kennedy Space Center, just a few miles north of SLC-40. SpaceX uses LC-39A as a launch pad for most Falcon 9 crew launches, all Falcon Heavy missions, and, in the future, flights of the company’s gigantic next-generation rocket, Starship. SpaceX foresees Starship as a replacement for Falcon 9 and Falcon Heavy, but the company’s continuing investment in Falcon-related infrastructure shows the workhorse rocket will stick around for a while.

Former NASA chief says United States likely to lose second lunar space race

The hearing, titled “There’s a Bad Moon on the Rise: Why Congress and NASA Must Thwart China in the Space Race,” had no witnesses who disagreed with this viewpoint. They included Allen Cutler, CEO of the Coalition for Deep Space Exploration, the chief lobbying organization for SLS, Orion, and Gateway; Jim Bridenstine, former NASA Administrator who now leads government operations for United Launch Alliance; Mike Gold of Redwire, a Gateway contractor; and Lt. General John Shaw, former Space Command official.

The hearing before the committee chaired by Cruz, Commerce, Science, and Transportation, included the usual mishmash of parochial politics, lobbying for traditional space, back slapping, and fawning—at one point, Gold, a Star Trek fan, went so far as to assert that Cruz is the “Captain Kirk” of the US Senate.

Beyond this, however, there was a fair amount of teeth gnashing about the fact that the United States faces a serious threat from China, which appears to be on course to put humans on the Moon before NASA can return there with the Artemis Program. China aims to land humans at the South Pole before the year 2030.

NASA likely to lose “race”

Bridenstine, who oversaw the creation of the Artemis Program half a decade ago, put it most bluntly: “Unless something changes, it is highly unlikely the United States will beat China’s projected timeline to the Moon’s surface,” he said.

Bridenstine and others on the panel criticized the complex nature of SpaceX’s Starship-based lunar lander, which NASA selected in April 2021 as a means to get astronauts down to the lunar surface and back. The proposal relies on Starship being refueled in low-Earth orbit by multiple Starship tanker launches.

Trump’s move of SPACECOM to Alabama has little to do with national security

President Donald Trump announced Tuesday that US Space Command will be relocated from Colorado to Alabama, returning to the Pentagon’s plans for the command’s headquarters from the final days of Trump’s first term in the White House.

The headquarters will move to the Army’s Redstone Arsenal in Huntsville, Alabama. Trump made the announcement in the Oval Office, flanked by Republican members of the Alabama congressional delegation.

The move will “help America defend and dominate the high frontier,” Trump said. It also marks another twist on a contentious issue that has pitted Colorado and Alabama against one another in a fight for the right to be home to the permanent headquarters of Space Command (SPACECOM), a unified combatant command responsible for carrying out military operations in space.

Space Command is separate from the Space Force and is made up of personnel from all branches of the armed services. The Space Force, on the other hand, is charged with supplying personnel and technology for use by multiple combatant commands. The newest armed service, established in 2019 during President Trump’s first term, is part of the Department of the Air Force, which also had the authority for recommending where to base Space Command’s permanent headquarters.

“US Space Command stands ready to carry out the direction of the president following today’s announcement of Huntsville, Alabama, as the command’s permanent headquarters location,” SPACECOM wrote on its official X account.

Military officials in the first Trump administration considered potential sites in Colorado, Florida, Nebraska, New Mexico, and Texas before the Air Force recommended basing Space Command in Huntsville, Alabama, on January 13, 2021, a week before Trump left office.

Members of Colorado’s congressional delegation protested the decision, suggesting the recommendation was political. Trump won a larger share of votes in Alabama in 2016, 2020, and 2024 than in any of the other states in contention. On average, a higher percentage of Colorado’s citizens cast their votes against Trump than in the other five states vying for Space Command’s permanent headquarters.

Trump’s reasons

Trump cited three reasons Tuesday for basing Space Command in Alabama. He noted Redstone Arsenal’s proximity to other government and industrial space facilities, the persistence of Alabama officials in luring the headquarters away from Colorado, and Colorado’s use of mail-in voting, a policy that has drawn Trump’s ire but is wholly unrelated to military space matters.

“That played a big factor, also,” Trump said of Colorado’s mail-in voting law.

None of the reasons for the relocation that Trump mentioned in his remarks on Tuesday explained why Alabama is a better place for Space Command’s headquarters than Colorado, although the Air Force has pointed to cost savings as a rationale for the move.

A Government Accountability Office (GAO) investigation concluded in 2022 that the Air Force did not follow “best practices” in formulating its recommendation to place Space Command at Redstone Arsenal, leading to “significant shortfalls in its transparency and credibility.”

A separate report in 2022 from the Pentagon’s own inspector general concluded the Air Force’s basing decision process was “reasonable” and complied with military policy and federal law, but criticized the decision-makers’ record-keeping.

Former President Joe Biden’s secretary of the Air Force, Frank Kendall, stood by the recommendation in 2023 to relocate Space Command to Alabama, citing an estimated $426 million in cost savings due to lower construction and personnel costs in Huntsville relative to Colorado Springs. However, since then, Space Command achieved full operational capability at Peterson Space Force Base, Colorado.

Army Gen. James Dickinson, head of Space Command from 2020 until 2023, favored keeping the headquarters in Colorado, according to a separate inspector general report released earlier this year.

“Mission success is highly dependent on human capital and infrastructure,” Dickinson wrote in a 2023 memorandum to the secretary of the Air Force. “There is risk that most of the 1,000 civilians, contractors, and reservists will not relocate to another location.”

One division chief within Space Command’s plans and policy directorate told the Pentagon’s inspector general in May 2024 that they feared losing 90 percent of their civilian workforce if the Air Force announced a relocation. A representative of another directorate told the inspector general’s office that they could say “with certainty” only one of 25 civilian employees in their division would move to a new headquarters location.

Officials at Redstone Arsenal and information technology experts at Space Command concluded it would take three to four years to construct temporary facilities in Huntsville with the same capacity, connectivity, and security as those already in use in Colorado Springs, according to the DoD inspector general.

Tension under Biden

Essentially, the inspector general reported, officials at the Pentagon made cost savings their top consideration in where to garrison Space Command. Leaders at Space Command prioritized military readiness.

President Biden decided in July 2023 that Space Command’s headquarters would remain in Colorado Springs. The decision, according to the Pentagon’s press secretary at the time, would “ensure peak readiness in the space domain for our nation during a critical period.” Alabama lawmakers decried Biden’s decision in favor of Colorado, claiming it, too, was politically motivated.

Space Command reached full operational capability at its headquarters at Peterson Space Force Base, Colorado, two years ahead of schedule in December 2023. At the time, Space Command leaders said they could only declare Space Command fully operational upon the selection of a permanent headquarters.

Now, a year-and-a-half later, the Trump administration will uproot the headquarters and move it more than 1,000 miles to Alabama. But it hasn’t been smooth sailing for Space Command in Colorado.

A new report by the GAO published in May said Space Command faced “ongoing personnel, facilities, and communications challenges” at Peterson, despite the command’s declaration of full operational capability. Space Command officials told the GAO the command’s posture at Peterson is “not sustainable long term and new military construction would be needed” in Colorado Springs.

Space Command was originally established in 1985. The George W. Bush administration later transferred responsibility for military space activities to the US Strategic Command, as part of a post-9/11 reorganization of the military’s command structure. President Trump reestablished Space Command in 2019, months before Congress passed legislation to make the Space Force the nation’s newest military branch.

Throughout its existence, Space Command has been headquartered at Peterson Space Force Base in Colorado Springs. But now, Pentagon officials say the growing importance of military space operations and potentially space warfare requires Space Command to occupy a larger headquarters than the existing facility at Peterson.

Peterson Space Force Base is also the headquarters of North American Aerospace Defense Command, or NORAD, US Northern Command, and Space Operations Command, all of which work closely with Space Command. Space Command officials told the GAO there were benefits in being co-located with operational space missions and centers, where engineers and operators control some of the military’s most important spacecraft in orbit.

Several large space companies also have significant operations or headquarters in the Denver metro area, including Lockheed Martin, United Launch Alliance, BAE Systems, and Sierra Space.

Colorado’s congressional delegation—six Democrats and four Republicans—issued a joint statement Tuesday expressing their disappointment in Trump’s decision.

“Today’s decision to move US Space Command’s headquarters out of Colorado and to Alabama will directly harm our state and the nation,” the delegation said in a statement. “We are united in fighting to reverse this decision. Bottom line—moving Space Command headquarters weakens our national security at the worst possible time.”

The relocation of Space Command headquarters is estimated to bring about 1,600 direct jobs to Huntsville, Alabama. The area surrounding the headquarters will also derive indirect economic benefits, something Colorado lawmakers said they fear will come at the expense of businesses and workers in Colorado Springs.

“Being prepared for any threats should be the nation’s top priority; a crucial part of that is keeping in place what is already fully operational,” the Colorado lawmakers wrote. “Moving Space Command would not result in any additional operational capabilities than what we have up and running in Colorado Springs now. Colorado Springs is the appropriate home for US Space Command, and we will take the necessary action to keep it there.”

Alabama’s senators and representatives celebrated Trump’s announcement Tuesday.

“The Air Force originally selected Huntsville in 2021 based 100 percent on merit as the best choice,” said Rep. Robert Aderholt (R-Alabama). “President Biden reversed that decision based on politics. This wrong has been righted and Space Command will take its place among Huntsville’s world-renowned space, aeronautics, and defense leaders.”

Democratic Colorado Gov. Jared Polis said in a statement that the Trump administration should provide “full transparency” and the “full details of this poor decision.”

“We hope other vital military units and missions are retained and expanded in Colorado Springs. Colorado remains an ideal location for future missions, including Golden Dome,” Polis said, referring to the Pentagon’s proposed homeland missile defense system.
