CDC data confirms US is 2 months away from losing measles elimination status

Unsurprising

This 9171 subtype “continues, unfortunately uninterrupted, across multiple jurisdictions,” David Sugerman, who leads the CDC measles response, said on the call.

According to the Times, local health officials are pessimistic that they’ll be able to stamp out the virus’s spread, saying that vaccination efforts have had “limited” impact. As Ars reported previously, vaccination rates are dangerously low in two measles hotspots: northwestern Mohave County, Arizona, and the southwest health district of Utah. Vaccination rates among kindergartners in the 2024–2025 school year were 78.4 percent and 80.7 percent, respectively. That’s well below the 95 percent target needed to keep the virus from spreading onward in the communities.

In addition, public health officials in Arizona and Utah have reported barriers to responding to the outbreak. Around a quarter of cases don’t know how they were exposed, suggesting cases and exposures are being missed. In late October, health officials in Salt Lake County, Utah, said that a person likely infected with measles refused to cooperate with their investigation, leaving them unable to confirm the probable case.

David Kimberlin, who sits on a panel of experts that analyzes measles data for the United States’ elimination status review, told the Times, “It would not surprise me in the least if there’s continued spread across these next several months.”

To date, the CDC has tallied 1,723 measles cases across 42 states. Most (87 percent) of those cases were linked to outbreaks, of which there have been 45 this year. For context, there were 16 outbreaks and a total of 285 measles cases in the US last year. This year’s measles cases mark a 33-year high.

If things in America weren’t stupid enough, Texas is suing Tylenol maker

While the underlying cause or causes of autism spectrum disorder remain elusive and appear likely to be a complex interplay of genetic and environmental factors, President Trump and his anti-vaccine health secretary Robert F. Kennedy Jr.—neither of whom have any scientific or medical background whatsoever—have decided to pin the blame on Tylenol, a common pain reliever and fever reducer that has no proven link to autism.

And now, Texas Attorney General Ken Paxton is suing the maker of Tylenol, Kenvue and Johnson & Johnson, who previously sold Tylenol, claiming that they have been “deceptively marketing Tylenol” knowing that it “leads to a significantly increased risk of autism and other disorders.”

To back that claim, Paxton relies on the “considerable body of evidence… recently highlighted by the Trump Administration.”

Of course, there is no “considerable” evidence for this claim, only tenuous associations and conflicting studies. Trump and Kennedy’s justification for blaming Tylenol was revealed in a rambling, incoherent press conference last month, in which Trump spoke of a “rumor” about Tylenol and his “opinion” on the matter. Still, he firmly warned against its use, saying well over a dozen times: “don’t take Tylenol.”

“Don’t take Tylenol. There’s no downside. Don’t take it. You’ll be uncomfortable. It won’t be as easy maybe, but don’t take it if you’re pregnant. Don’t take Tylenol and don’t give it to the baby after the baby is born,” he said.

“Scientifically unfounded”

As Ars has reported previously, there are some studies that have found an association between use of Tylenol (aka acetaminophen or paracetamol) and a higher risk of autism. But, many of the studies finding such an association have significant flaws. Other studies have found no link. That includes a highly regarded Swedish study that compared autism risk among siblings with different acetaminophen exposures during pregnancy, but otherwise similar genetic and environmental risks. Acetaminophen didn’t make a difference, suggesting other genetic and/or environmental factors might explain any associations. Further, even if there is a real association (aka a correlation) between acetaminophen use and autism risk, that does not mean the pain reliever is the cause of autism.

Texas lawmakers double down on Discovery, call for DOJ investigation into Smithsonian

It is unknown what, if any, actions Roberts took in response to the letter. The Smithsonian issued a statement asserting it “does not engage in direct or grassroots lobbying” and that its staff has “acted in accordance with all governing rules and regulations.”

The Smithsonian has also stated that it is not a part of the federal government and holds clear title to Discovery, as transferred by NASA in 2012. As such, any attempt to remove Discovery from its collection would be unprecedented. The Congressional Research Service raised similar concerns about ownership in a briefing paper it prepared for lawmakers.

The crux of the concerns seems to be a letter the Smithsonian sent to the congressional authorizing and appropriating committees, as first shared by KeepTheShuttle, a grassroots organization founded to support Discovery staying at the National Air and Space Museum’s Steven F. Udvar-Hazy Center in Chantilly, Virginia. In that letter, the Smithsonian cited a cost of $35 million to $65 million more than the $85 million authorized by the Big Beautiful Bill Act (and that excluded the construction of a display facility, which was included in the legislation’s budget).

To chop or not to chop

The Smithsonian, together with NASA, also expressed concern that “Discovery will have to undergo significant disassembly to be moved.”

That possibility, along with the logistics and costs of making the move, resulted in Sens. Mark Kelly (D-Ariz.), Dick Durbin (D-Ill.), Mark Warner (D-Va.), and Tim Kaine (D-Va.) sending their own letter to the Senate Committee on Appropriations to block funding for the move. Kelly, a former NASA astronaut who flew on Discovery twice, and Warner also released a video on social media contrasting chopping vegetables to chopping up the space shuttle.

“To get it down there [to Houston], you would have to rip off the wings. The head shield, all of those tiles on the bottom, would be stripped off. The white thermal blankets? Gone,” Kelly said in the video released on Tuesday. “If Ted Cruz and Cornyn think they are putting this thing back together, I want to see them get out there. They’ll be out there for the next 10 years trying to figure this out.

“This is the dumbest plan I’ve ever heard in nearly five years in the United States Senate,” said Kelly.

Big Tech sues Texas, says age-verification law is “broad censorship regime”

Texas minors also challenge law

The Texas App Store Accountability Act is similar to laws enacted by Utah and Louisiana. The Texas law is scheduled to take effect on January 1, 2026, while the Utah and Louisiana laws are set to be enforced starting in May and July, respectively.

The Texas law is also being challenged in a different lawsuit filed by a student advocacy group and two Texas minors.

“The First Amendment does not permit the government to require teenagers to get their parents’ permission before accessing information, except in discrete categories like obscenity,” attorney Ambika Kumar of Davis Wright Tremaine LLP said in an announcement of the lawsuit. “The Constitution also forbids restricting adults’ access to speech in the name of protecting children. This law imposes a system of prior restraint on protected expression that is presumptively unconstitutional.”

Davis Wright Tremaine LLP said the law “extends far beyond social media to mainstream educational, news, and creative applications, including Wikipedia, search apps, and internet browsers; messaging services like WhatsApp and Slack; content libraries like Audible, Kindle, Netflix, Spotify, and YouTube; educational platforms like Coursera, Codecademy, and Duolingo; news apps from The New York Times, The Wall Street Journal, ESPN, and The Atlantic; and publishing tools like Substack, Medium, and CapCut.”

Both lawsuits against Texas argue that the law is preempted by the Supreme Court’s 2011 decision in Brown v. Entertainment Merchants Association, which struck down a California law restricting the sale of violent video games to children. The Supreme Court said in Brown that a state’s power to protect children from harm “does not include a free-floating power to restrict the ideas to which children may be exposed.”

The tech industry has sued Texas over multiple laws related to content moderation. In 2022, the Supreme Court blocked a Texas law that prohibits large social media companies from moderating posts based on a user’s viewpoint. Litigation in that case is ongoing. In a separate case decided in June 2025, the Supreme Court upheld a Texas law that requires age verification on porn sites.

SpaceX finally got exactly what it needed from Starship V2


This was the last flight of SpaceX’s second-gen Starship design. Version 3 arrives next year.

SpaceX closed a troubled but instructive chapter in its Starship rocket program Monday with a near-perfect test flight that carried the stainless steel spacecraft halfway around the world from South Texas to the Indian Ocean.

The rocket’s 33 methane-fueled Raptor engines roared to life at 6: 23 pm CDT (7: 23 pm EDT; 23: 23 UTC), throttling up to generate some 16.7 million pounds of thrust, by large measure more powerful than any rocket before Starship. Moments later, the 404-foot-tall (123.1-meter) rocket began a vertical climb away from SpaceX’s test site in Starbase, Texas, near the US-Mexico border.

From then on, the rocket executed its flight plan like clockwork. This was arguably SpaceX’s most successful Starship test flight to date. The only flight with a similar claim occurred one year ago Monday, when the company caught the rocket’s Super Heavy booster back at the launch pad after soaring to the uppermost fringes of the atmosphere. But that flight didn’t accomplish as much in space.

“Starship’s eleventh flight test reached every objective, providing valuable data as we prepare the next generation of Starship and Super Heavy,” SpaceX posted on X.

SpaceX didn’t try to recover the Super Heavy booster on this flight, but the goals the company set before the launch included an attempt to guide the enormous rocket stage to a precise splashdown in the Gulf of Mexico off the coast of South Texas. The booster, reused from a previous flight in March, also validated a new engine configuration for its landing burn, first reigniting 13 of its engines, then downshifting to five, then to three for the final hover.

That all worked, along with pretty much everything else apart from an indication on SpaceX’s livestream that Starship’s Super Heavy booster stage lost an engine early in its descent. The malfunctioning engine had no impact on the rest of the flight.

Flight 11 recap

This was the fifth and final flight of Starship’s second-generation configuration, known as Version 2, or V2. It was the 11th full-scale Starship test flight overall.

It took a while for Starship V2 to meet SpaceX’s expectations. The first three Starship V2 launches in January, March, and May ended prematurely due to problems in the rocket’s propulsion and a fuel leak, breaking a string of increasingly successful Starship flights since 2023. Another Starship V2 exploded on a test stand in Texas in June, further marring the second-gen rocket’s track record.

But SpaceX teams righted the program with a good test flight in August, the first time Starship V2 made it all the way to splashdown. Engineers learned a few lessons on that flight, including the inadequacy of a new metallic heat shield tile design that left a patch of orange oxidation down the side of the ship. They also found that another experiment with part of the ship’s heat shield showed promising results. This method involved using a soft “crunch wrap” material to seal the gaps between the ship’s ceramic tiles and prevent super-heated plasma from reaching the rocket’s stainless steel skin.

Technicians installed the crunch wrap material in more places for Flight 11, and a first look at the performance of the ship during reentry and splashdown suggested the heat shield change worked well.

After reaching space, Starship shut down its six Raptor engines and coasted across the Atlantic Ocean and Africa before emerging over the Indian Ocean just before reentry. During its time in space, Starship released eight Starlink satellite mockups mimicking the larger size of the company’s next-generation Starlink spacecraft. These new Starlink satellites will only be able to launch on Starship.

Starship also reignited one of its six engines for a brief maneuver to set up the ship’s trajectory for reentry. With that, the stage was set for the final act of the test flight. How would the latest version of SpaceX’s ever-changing heat shield design hold up against temperatures of 2,600° Fahrenheit (1,430° Celsius)?

The answer: Apparently quite well. While SpaceX has brought Starships back to Earth in one piece several times, this was the first time the ship made it through reentry relatively unscathed. Live video streaming from cameras onboard Starship showed a blanket of orange and purple plasma enveloping the rocket during reentry. This is now a familiar sight, thanks to connectivity with Starship through SpaceX’s Starlink broadband network.

What was different on Monday was the lack of any obvious damage to the heat shield or flaps throughout Starship’s descent, a promising sign for SpaceX’s chances of reusing the vehicle and its heat shield over and over again, without requiring any refurbishment. This, according to SpaceX’s Elon Musk, is the acid test for determining Starship’s overall success.

In the closing moments of Monday’s flight, Starship flexed its flaps to perform a “dynamic banking maneuver” over the Indian Ocean, then flipped upright and fired its engines to slow for splashdown, simulating maneuvers the rocket will execute on future missions returning to the launch site. That will be one of the chief goals for the next phase of Starship’s test campaign beginning next year.

Patience for V3

It will likely be at least a few months before SpaceX is ready to launch the next Starship flight. Technicians at Starbase are assembling the next Super Heavy booster and the first Starship V3 vehicle. Once integrated, the booster and ship are expected to undergo cryogenic testing and static-fire testing before SpaceX moves forward with launch.

“Focus now turns to the next generation of Starship and Super Heavy, with multiple vehicles currently in active build and preparing for tests,” SpaceX wrote on its website. “This next iteration will be used for the first Starship orbital flights, operational payload missions, propellant transfer, and more as we iterate to a fully and rapidly reusable vehicle with service to Earth orbit, the Moon, Mars, and beyond.”

Starship V3 will have larger propellant tanks to increase the rocket’s lifting capacity, upgraded Raptor 3 engines, and an improved payload compartment to support launches of real Starlink satellites. SpaceX will also use this version of the rocket for orbital refueling experiments, a long-awaited milestone for the Starship program now planned for sometime next year. Orbital refueling is a crucial enabler for future Starship flights beyond low-Earth orbit and is necessary for SpaceX to fulfill Musk’s ambition to send ships to Mars, the founder’s long-held goal for the company.

It’s also required for Starship flights to the Moon. NASA has signed contracts with SpaceX worth more than $4 billion to develop a human-rated derivative of Starship to land astronauts on the Moon as part of the agency’s Artemis program. The orbital refueling demonstration is a key milestone on the NASA lunar lander contract. Getting this done as soon as possible is vitally important to NASA, which is seeing its Artemis Moon landing schedule slip, in part due to Starship delays.

None of it can really get started until Starship V3 is flying reliably and flying often. If the first Starship V3 flight goes well, SpaceX may attempt to put the next vehicle—Flight 13—into orbit to verify the ship’s endurance in space. At some point, SpaceX will make the first attempt to bring a ship home from orbit for a catch by the launch tower, similar to how SpaceX has caught Super Heavy boosters returning from the edge of space.

But first, ground crews are wrapping up work on a second Starship launch pad designed to accommodate the upgraded, taller Starship V3 rocket. Monday’s flight marked the final launch from Pad 1 in its existing form. The differences with the second launch pad include its flame trench, a common fixture at many launch pads around the world. Pad 1 was not built with a flame trench, but instead features an elevated launch mount where the rocket sits prior to liftoff.

SpaceX is expected to overhaul Pad 1 in the coming months to reactivate it as a second launch pad option for Starship V3. All of this work is occurring in Texas as SpaceX prepares to bring online more Starship launch pads at Cape Canaveral Space Force Station and Kennedy Space Center in Florida. SpaceX says it will need a lot of pads to ramp up Starship to monthly, weekly, and eventually daily flights.

another-setback-for-firefly-aerospace’s-beleaguered-rocket-program

Another setback for Firefly Aerospace’s beleaguered rocket program

Alpha’s track record

The booster destroyed Monday was slated to fly on the seventh launch of Firefly’s Alpha rocket, an expendable, two-stage launch vehicle capable of placing a payload of a little over 2,200 pounds, or a metric ton, into low-Earth orbit.

This upcoming launch was supposed to be the Alpha rocket’s return to flight after an in-flight failure in April, when the upper stage’s engine shut down before the rocket could reach orbit and deploy its satellite payload.

But engineers traced the cause of the failure to the first stage, which ruptured milliseconds after stage separation, sending out a blast wave that damaged the upper stage engine. Investigators concluded the most likely cause of the rupture was thermal damage from a phenomenon known as plume-induced flow separation. This occurs when a rocket plume expands at higher altitudes, creating conditions that, in some cases, can draw the hot exhaust plume farther up the vehicle.

The Alpha rocket flew a higher angle of attack on the April launch than it did on prior missions, exposing one side of the rocket to more heating from the recirculated engine exhaust plume. At stage separation, the thermal damage led to the booster’s structural failure. Firefly said it would add a thicker thermal protection barrier to the booster for future missions and reduce the angle of attack during key phases of flight.

Firefly announced last month that it received clearance from the Federal Aviation Administration to resume Alpha launches.

The rocket already had a mixed record heading into this year. Firefly has only achieved two fully successful missions in six launches of the Alpha rocket. Two missions put their payloads into off-target orbits, and two Alpha launches—the rocket’s debut in 2021 and the flight in April—failed to reach orbit at all.

senators-try-to-halt-shuttle-move,-saying-“little-evidence”-of-public-demand

Senators try to halt shuttle move, saying “little evidence” of public demand

“Houston’s disappointment in not being selected is wholly understandable,” the four senators wrote, “but removing an item from the National Collection is not a viable solution.”

In July, Cornyn and Cruz successfully added language to the “One Big Beautiful Bill Act” championed by President Donald Trump, which enabled acting NASA Administrator Sean Duffy to then identify Discovery for relocation. The provision also called for $85 million to be made available to transport and display the shuttle in Houston.

“There are also profound financial challenges associated with this transfer,” wrote Kelly. Warner, Kaine, and Durbin. “The Smithsonian estimates that transporting Discovery from Virginia to Houston could cost more than $50 million, with another $325 million needed for planning, exhibit reconstruction, and new facilities.”

“Dedicating hundreds of millions of taxpayer dollars to move an artifact that is already housed, displayed, and preserved in a world-class facility is both inefficient and unjustifiable,” the senators wrote.

Risks and rewards

Then there are the logistical challenges with relocating Discovery, which could result in damaging it, “permanently diminishing its historical and cultural value for future generations.”

“Moving Discovery by barge or road would be far more complex [than previous shuttle moves], exposing it to saltwater, weather, and collision risks across a journey several times longer,” the letter reads. “As a one-of-a-kind artifact that has already endured the stresses of spaceflight, Discovery is uniquely vulnerable to these hazards. The heat tiles that enabled repeated shuttle missions become more fragile with age, and they are irreplaceable.”

Kelly, who previously lived in Houston when he was part of the space program, agrees that the city is central to NASA’s human spaceflight efforts, but, along with Warner, Kaine, and Durbin, points out that displaying Discovery would come with another cost: an admission fee, limiting public access to the shuttle.

“The Smithsonian is unique among museums for providing visitors with access to a national treasure meant to inspire the American public without placing economic barriers,” wrote the senators.

Under the terms of the act, NASA has until January 4, 2027 (18 months after the bill’s enactment) to transfer Discovery to Space Center Houston. For its part, the Smithsonian says that it owns the title to Discovery and, as the institution is not part of the federal government, the orbiter is no longer the government’s to move.

Horrifying screwworm infection confirmed in US traveler after overseas trip

Flesh-eating screwworm larvae poised to invade the US have snuck into Maryland via the flesh of a person who had recently traveled to El Salvador, upping anxiety about the ghastly—and economically costly—parasite.

Reuters was first to report the case early Monday, quoting Andrew Nixon, spokesperson for the US Department of Health and Human Services, who said in an email that the Centers for Disease Control and Prevention had confirmed the case on August 4 in a person who had returned from a trip to El Salvador.

While other outlets have since reported that the screwworm case found in Maryland is the first human case in the US, or first travel-related case in the US, or the first case in years—none of those things are true. Screwworms are endemic in parts of South America and the Caribbean and travel-related cases have always been a threat and occasionally pop up in the US. While the CDC doesn’t keep a public tally of the cases, experts at the agency have noted several travel-related human cases in the US in recent years, including one as recent as last year.

The new case in Maryland doesn’t change anything in the US. “The risk to public health in the United States from this introduction is very low,” Nixon wrote to Reuters. But, what has changed is that the risk of an incursion at the US-Mexico border is no longer low—in fact it’s rather high currently.

Savage parasites

Screwworms were once endemic to the US before a massive eradication effort that began in the 1950s drove the population out of the US and Central America. The flies were held at bay with a biological barrier of constant releases of sterile male flies along the Darién Gap at the border of Panama and Colombia. The flies were declared eradicated from Panama in 2006. But, in 2022, the barrier was breached and the flies have worked their way back up through Central America, including El Salvador, since then. Now they are merely 370 miles or less from the Texas border, and state and federal agencies are preparing for an invasion, including with plans to build a sterile fly facility in the state.

Time is running out for SpaceX to make a splash with second-gen Starship


SpaceX is gearing up for another Starship launch after three straight disappointing test flights.

STARBASE, Texas—A beehive of aerospace technicians, construction workers, and spaceflight fans descended on South Texas this weekend in advance of the next test flight of SpaceX’s gigantic Starship rocket, the largest vehicle of its kind ever built.

Towering 404 feet (123.1 meters) tall, the rocket was supposed to lift off during a one-hour launch window beginning at 6: 30 pm CDT (7: 30 pm EDT; 23: 30 UTC) Sunday. But SpaceX called off the launch attempt about an hour before liftoff to investigate a ground system issue at Starbase, located a few miles north of the US-Mexico border.

SpaceX didn’t immediately confirm when it might try again to launch Starship, but it could happen as soon as Monday evening at the same time.

It will take about 66 minutes for the rocket to travel from the launch pad in Texas to a splashdown zone in the Indian Ocean northwest of Australia. You can watch the test flight live on SpaceX’s official website. We’ve also embedded a livestream from Spaceflight Now and LabPadre below.

This will be the 10th full-scale test flight of Starship and its Super Heavy booster stage. It’s the fourth flight of an upgraded version of Starship conceived as a stepping stone to a more reliable, heavier-duty version of the rocket designed to carry up to 150 metric tons, or some 330,000 pounds, of cargo to pretty much anywhere in the inner part of our Solar System.

But this iteration of Starship, known as Block 2 or Version 2, has been anything but reliable. After reeling off a series of increasingly successful flights last year with the first-generation Starship and Super Heavy booster, SpaceX has encountered repeated setbacks since debuting Starship Version 2 in January.

Now, there are just two Starship Version 2s left to fly, including the vehicle poised for launch this week. Then, SpaceX will move on to Version 3, the design intended to go all the way to low-Earth orbit, where it can be refueled for longer expeditions into deep space.

Starship’s promised cargo capacity is unparalleled in the history of rocketry. The privately developed rocket’s enormous size, coupled with SpaceX’s plan to make it fully reusable, could enable cargo and human missions to the Moon and Mars. SpaceX’s most conspicuous contract for Starship is with NASA, which plans to use a version of the ship as a human-rated Moon lander for the agency’s Artemis program. With this contract, Starship is central to the US government’s plans to try to beat China back to the Moon.

Closer to home, SpaceX intends to use Starship to haul massive loads of more powerful Starlink Internet satellites into low-Earth orbit. The US military is interested in using Starship for a range of national security missions, some of which could scarcely be imagined just a few years ago. SpaceX wants its factory to churn out a Starship rocket every day, approximately the same rate Boeing builds its workhorse 737 passenger jets.

Starship, of course, is immeasurably more complex than an airliner, and it sees temperature extremes, aerodynamic loads, and vibrations that would destroy a commercial airplane.

For any of this to become reality, SpaceX needs to begin ticking off a lengthy to-do list of technical milestones. The interim objectives include things like catching and reusing Starships and in-orbit ship-to-ship refueling, with a final goal of long-duration spaceflight to reach the Moon and stay there for weeks, months, or years. For a time late last year, it appeared as if SpaceX might be on track to reach at least the first two of these milestones by now.

Instead, SpaceX’s schedule for catching and reusing Starships, and refueling ships in orbit, has slipped well into next year. A Moon landing is probably at least several years away. And a touchdown on Mars? Maybe in the 2030s. Before Starship can sniff those milestones, engineers must get the rocket to survive from liftoff through splashdown. This would confirm that recent changes made to the ship’s heat shield work as expected.

Three test flights attempting to do just this ended prematurely in January, March, and May. These failures prevented SpaceX from gathering data on several different tile designs, including insulators made of ceramic and metallic materials, and a tile with “active cooling” to fortify the craft as it reenters the atmosphere.

The heat shield is supposed to protect the rocket’s stainless steel skin from temperatures reaching 2,600° Fahrenheit (1,430° Celsius). During last year’s test flights, it worked well enough for Starship to guide itself to an on-target controlled splashdown in the Indian Ocean, halfway around the world from SpaceX’s launch site in Starbase, Texas.

But the ship lost some of its tiles during each flight last year, causing damage to the ship’s underlying structure. While this wasn’t bad enough to prevent the vehicle from reaching the ocean intact, it would cause difficulties in refurbishing the rocket for another flight. Eventually, SpaceX wants to catch Starships returning from space with giant robotic arms back at the launch pad. The vision, according to SpaceX founder and CEO Elon Musk, is to recover the ship, quickly mount it on another booster, refuel it, and launch it again.

If SpaceX can accomplish this, the ship must return from space with its heat shield in pristine condition. The evidence from last year’s test flights showed engineers had a long way to go for that to happen.

The Starship setbacks this year have been caused by problems in the ship’s propulsion and fuel systems. Another Starship exploded on a test stand in June at SpaceX’s sprawling rocket development facility in South Texas. SpaceX engineers identified different causes for each of the failures. You can read about them in our previous story.

Apart from testing the heat shield, the goals for this week’s Starship flight include testing an engine-out capability on the Super Heavy booster. Engineers will intentionally disable one of the booster’s Raptor engines used to slow down for landing, and instead use another Raptor engine from the rocket’s middle ring. At liftoff, 33 methane-fueled Raptor engines will power the Super Heavy booster off the pad.

SpaceX won’t try to catch the booster back at the launch pad this time, as it did on three occasions late last year and earlier this year. The booster catches have been one of the bright spots for the Starship program as progress on the rocket’s upper stage floundered. SpaceX reused a previously flown Super Heavy booster for the first time on the most recent Starship launch in May.

The booster landing experiment on this week’s flight will happen a few minutes after launch over the Gulf of Mexico east of the Texas coastline. Meanwhile, six Raptor engines will fire until approximately T+plus 9 minutes to accelerate the ship, or upper stage, into space.

The ship is programmed to release eight Starlink satellite simulators from its payload bay in a test of the craft’s payload deployment mechanism. That will be followed by a brief restart of one of the ship’s Raptor engines to adjust its trajectory for reentry, set to begin around 47 minutes into the mission.

If Starship makes it that far, that will be when engineers finally get a taste of the heat shield data they were hungry for at the start of the year.

This story was updated at 8: 30 pm EDT after SpaceX scrubbed Sunday’s launch attempt.

Texas prepares for war as invasion of flesh-eating flies appears imminent

Past success

As the flies’ host and geographic range expand, pressure is intensifying to control the flies—something many countries have managed to do in the past.

Decades ago, screwworms were endemic throughout Central America and the southern US. However, governments across the regions used intensive, coordinated control efforts to push the flies southward. Screwworms were eliminated from the US around 1966, and were pushed downward through Mexico in the 1970s and 1980s. They were eventually declared eliminated from Panama in 2006, with the population held at bay by a biological barrier at the Darién Gap, at the border of Panama and Colombia. However, in 2022, the barrier was breached, and the flies began advancing northward, primarily through unmonitored livestock movements. The latest surveillance suggests the flies are now about 370 miles south of Texas.

The main method to wipe out screwworms is the sterile insect technique (SIT), which exploits a weakness in the fly’s life cycle since they tend to only mate once. In the 1950s, researchers at the US Department of Agriculture figured out they could use gamma radiation to sterilize male flies without affecting their ability to find mates. They then bred massive amounts of male flies, sterilized them, and carpet-bombed infested areas with aerial releases, which tanked the population.

Panama, in partnership with the US, maintained the biological barrier at the Colombian border with continual sterile-fly bombings for years. But as the flies approached this year, the USDA shifted its aerial deliveries to Mexico. In June, the USDA announced plans to set up a new sterile fly facility in Texas for aerial deliveries to northern Mexico. And last month, the USDA halted livestock trade from southern entry points.

Miller said in the announcement today that SIT is no longer enough, and Texas is taking its own steps. Those include the new bait, insecticides, and new feed for livestock and deer laced with the anti-parasitic drug ivermectin. Miller also said that the state aims to develop a vaccine for cattle that could kill larvae, but such a shot is still in development.

Texas politicians warn Smithsonian it must not lobby to retain its space shuttle

(Oddly, Cornyn and Weber’s letter to Roberts described the law as requiring Duffy “to transfer a space vehicle involved in the Commercial Crew Program” rather than choosing a destination NASA center related to the same, as the bill actually reads. Taken as written, if that was indeed their intent, Discovery and the other retired shuttles would be exempt, as the winged orbiters were never part of that program. A request for clarification sent to both Congress members’ offices was not immediately answered.)

In the letter, Cornyn and Weber cited the Anti-Lobbying Act as restricting the use of funds provided by the federal government to “influence members of the public to pressure Congress regarding legislation or appropriations matters.”

“As the Smithsonian Institution receives annual appropriations from Congress, it is subject to the restrictions imposed by this statute,” they wrote.

The money that Congress allocates to the Smithsonian accounts for about two-thirds of the Institution’s annual budget, primarily covering federal staff salaries, collections care, facilities maintenance, and the construction and revitalization of the buildings that house the Smithsonian’s 21 museums and other centers.

Pols want Smithsonian to stay mum

As evidence of the Smithsonian’s alleged wrongdoing, Cornyn and Weber cited a July 11 article by Zach Vasile for Flying Magazine, which ran under the headline “Smithsonian Pushing Back on Plans to Relocate Space Shuttle.” Vasile quoted from a message the Institution sent to Congress saying that there was no precedent for removing an object from its collection to send it elsewhere.

The Texas officials wrote that the anti-lobbying restrictions apply to “staff time or public relations resources” and claimed that the Smithsonian’s actions did not fall under the law’s exemptions, including “public speeches, incidental expenditures for public education or communications, or activities unrelated to legislation or appropriations.”

Cornyn and Weber urged Roberts, as the head of the Smithsonian’s Board of Regents, to “conduct a comprehensive internal review” as it applied to how the institution responded to the One Big Beautiful Bill Act.

“Should the review reveal that appropriated funds were used in a manner inconsistent with the prohibitions outlined in the Anti-Lobbying Act, we respectfully request that immediate and appropriate corrective measures be implemented to ensure the Institution’s full compliance with all applicable statutory and ethical obligations,” Cornyn and Weber wrote.

Houston, you’ve got a space shuttle… only NASA won’t say which one


An orbiter by any other name…

“The acting administrator has made an identification.”

The head of NASA has decided to move one of the agency’s retired space shuttles to Houston, but which one seems to still be up in the air.

Senator John Cornyn (R-Texas), who earlier this year introduced and championed an effort to relocate the space shuttle Discovery from the Smithsonian to Space Center Houston, issued a statement on Tuesday evening (August 5) applauding the decision by acting NASA Administrator Sean Duffy.

“There is no better place for one of NASA’s space shuttles to be displayed than Space City,” said Cornyn in the statement. “Since the inception of our nation’s human space exploration program, Houston has been at the center of our most historic achievements, from training the best and brightest to voyage into the great unknown to putting the first man on the moon.”

Keeping the shuttle a secret, for some reason

The senator did not state which of NASA’s winged orbiters would be making the move. The legislation that required Duffy to choose a “space vehicle” that had “flown in space” and “carried people” did not specify an orbiter by name, but the language in the “One Big Beautiful Bill” that President Donald Trump signed into law last month was inspired by Cornyn and fellow Texas Senator Ted Cruz’s bill to relocate Discovery.

“The acting administrator has made an identification. We have no further public statement at this time,” said a spokesperson for Duffy in response to an inquiry.

It is not clear why the choice of orbiters is being held a secret. According to the bill, the decision was to be made “with the concurrence of an entity designated” by the NASA administrator to display the shuttle. Cornyn’s release only confirmed that Duffy had identified the location to be “a non-profit near the Johnson Space Center (JSC).”

Space Center Houston is owned by the Manned Space Flight Education Foundation, a 501(c)3 organization, and is the official visitor’s center for NASA’s Johnson Space Center.

“We continue to work on the basis that the shuttle identified is Discovery and proceed with our preparations for its arrival and providing it a world-class home,” Keesha Bullock, interim COO and chief communications and marketing officer at Space Center Houston, said in a statement.

Orbiter owners

Another possible reason for the hesitation to name an orbiter may be NASA’s ability, or rather inability, to identify one of its three remaining space-flown shuttles that is available to be moved.

NASA transferred the title for space shuttle Endeavour to the California Science Center in Los Angeles in 2012, and as such it is no longer US government property. (The science center is a public-private partnership between the state of California and the California Science Center Foundation.)

NASA still owns space shuttle Atlantis and displays it at its own Kennedy Space Center Visitor Complex in Florida.

Discovery, the fleet leader and “vehicle of record,” was the focus of Cornyn and Cruz’s original “Bring the Space Shuttle Home Act.” The senators said they chose Discovery because it was “the only shuttle still owned by the federal government and able to be transferred to Houston.”

For the past 13 years, Discovery has been on public display at the Steven F. Udvar-Hazy Center in Chantilly, Virginia, the annex for the Smithsonian’s National Air and Space Museum in Washington, DC. As with Endeavour, NASA signed over title upon the orbiter’s arrival at its new home.

As such, Smithsonian officials are clear: Discovery is no longer NASA’s to have or to move.

“The Smithsonian Institution owns the Discovery and holds it in trust for the American public,” read a statement from the National Air and Space Museum issued before Duffy made his decision. “In 2012, NASA transferred ‘all rights, title, interest and ownership’ of the shuttle to the Smithsonian.”

The Smithsonian operates as a trust instrumentality of the United States and is partially funded by Congress, but it is not part of any of the three branches of the federal government.

“The Smithsonian is treated as a federal agency for lots of things to do with federal regulations and state action, but that’s very different than being an agency of the executive branch, which it most certainly is not,” Nick O’Donnell, an attorney who specializes in legal issues in the museum and visual arts communities and co-chairs the Art, Cultural Property, and Heritage Law Committee of the International Bar Association, said in an interview.

“If there’s a document that accompanied the transfer of the space shuttle, especially if it says something like, ‘all rights, title, and interest,’ that’s a property transfer, and that’s it,” O’Donnell said.

“NASA has decided to transfer all rights, interest, title, and ownership of Discovery to the Smithsonian Institution’s National Air and Space Museum,” reads the signed transfer of ownership for space shuttle orbiter Discovery (OV-103), according to a copy of the paperwork obtained by collectSPACE.

The Congressional Research Service also raised the issue of ownership in its paper, “Transfer of a Space Vehicle: Issues for Congress.”

“The ability of the NASA Administrator to direct transfer of objects owned by non-NASA entities—including the Smithsonian and private organizations—is unclear and may be subject to question. This may, in turn, limit the range of space vehicles that may be eligible for transfer under this provision.”

Defending Discovery

The National Air and Space Museum also raised concerns about the safety of relocating the space shuttle now. The One Big Beautiful Bill allocated $85 million to transport the orbiter and construct a facility to display it. The Smithsonian contends it could be much more costly.

“Removing Discovery from the Udvar-Hazy Center and transporting it to another location would be very complicated and expensive, and likely result in irreparable damage to the shuttle and its components,” the museum’s staff said in a statement. “The orbiter is a fragile object and must be handled according to the standards and equipment NASA used to move it originally, which exceeds typical museum transport protocols.”

“Given its age and condition, Discovery is at even greater risk today. The Smithsonian employs world-class preservation and conservation methods, and maintaining Discovery‘s current conditions is critical to its long-term future,” the museum’s statement concluded.

The law directs NASA to transfer the space shuttle (the identified space vehicle) to Space Center Houston (the entity designated by the NASA administrator) within 18 months of the bill’s enactment, or January 4, 2027.

In the interim, an amendment to block funding the move is awaiting a vote by the full House of Representatives when its members return from summer recess in September.

“The forced removal and relocation of the Space Shuttle Discovery from the Smithsonian Institution’s Air and Space Museum is inappropriate, wasteful, and wrong. Neither the Smithsonian nor American taxpayers should be forced to spend hundreds of millions of dollars on this misguided effort,” said Rep. Joe Morelle (D-NY), who introduced the amendment.

A grassroots campaign, KeepTheShutle.org, has also raised objection to removing Discovery from the Smithsonian.

Perhaps the best thing the Smithsonian can do—if indeed it is NASA’s intention to take Discovery—is nothing at all, says O’Donnell.

“I would say the Smithsonian’s recourse is to keep the shuttle exactly where it is. It’s the federal government that has no recourse to take it,” O’Donnell said. “The space shuttle [Discovery] is the Smithsonian’s, and any law that suggests the intention to take it violates the Fifth Amendment on its face—the government cannot take private property.”
