Welcome to Edition 8.06 of the Rocket Report! Two of the world’s most storied rocket builders not named SpaceX achieved major successes this week. Arianespace’s Ariane 6 rocket launched from French Guiana on its third flight Tuesday night with a European weather satellite. Less than 20 minutes later, United Launch Alliance’s third Vulcan rocket lifted off from Florida on a US military mission. These are two of the three big rockets developed in the Western world that have made their orbital debuts in the last two years, alongside Blue Origin’s New Glenn launcher. Ariane 6 narrowly won the “race” to reach its third orbital flight, but if you look at it another way, Ariane 6 reached its third flight milestone 13 months after its inaugural launch. It took Vulcan more than 19 months, and New Glenn has flown just once. SpaceX’s Super Heavy/Starship rocket has flown nine times but has yet to reach orbit.

Sixth success for sea-launched Chinese rocket. Private Chinese satellite operator Geespace added 11 spacecraft to its expanding Internet of Things constellation on August 8, aiming to boost low-power connectivity in key emerging markets, Space News reports. The 11 satellites rode into orbit aboard a solid-fueled Jielong 3 (Smart Dragon 3) rocket lifting off from an ocean platform in the Yellow Sea off the coast of Rizhao, a city in eastern China’s Shandong province. This was the sixth flight of the Jielong 3, a rocket developed by a commercially oriented spinoff of the state-owned China Academy of Launch Vehicle Technology.
Mistaken for a meteor … The fourth stage of the Jielong 3 rocket, left in orbit after deploying its 11 satellite payloads, reentered the atmosphere late Sunday night. The fiery and destructive reentry created a fireball that streaked across the skies over Spain, the Spanish newspaper El Mundo reports. Many Spanish residents identified the streaking object as a meteor associated with the Perseid meteor shower. But it turned out to be a piece of China’s Jielong 3 rocket. Any debris that may have survived the scorching reentry likely fell into the Mediterranean Sea.

Portugal green-lights Azores spaceport. The Portuguese government has granted the Atlantic Spaceport Consortium a license to build and operate a rocket launch facility on the island of Santa Maria in the Azores, European Spaceflight reports. The Atlantic Spaceport Consortium (ASC) was founded in 2019 with the goal of developing a commercial spaceport on Santa Maria, 1,500 kilometers off the Portuguese mainland. In September 2024, the company showcased the island’s suitability as a launch site by launching two small solid-fuel amateur-class rockets that it developed in-house.
What’s on deck? … The spaceport license granted by Portugal’s regulatory authorities does not cover individual launches themselves. Those must be approved in a separate licensing process. It’s likely that the launch site on Santa Maria Island will initially host suborbital launches, including flights by the Polish rocket company SpaceForest. The European Space Agency has also selected Santa Maria as the landing site for the first flight of the Space Rider lifting body vehicle after it launches into orbit, perhaps in 2027.

Why is Jeff Bezos buying launches from Elon Musk? Early Monday morning, a Falcon 9 rocket lifted off from its original launch site in Florida. Remarkably, it was SpaceX’s 100th launch of the year. Perhaps even more notable was the rocket’s payload: two-dozen Project Kuiper satellites, which were dispensed into low-Earth orbit on target, Ars reports. This was SpaceX’s second launch of satellites for Amazon, which is developing a constellation to deliver low-latency broadband Internet around the world. SpaceX, then, just launched a direct competitor to its Starlink network into orbit. And it was for the founder of Amazon, Jeff Bezos, who owns a rocket company of his own in Blue Origin.
Several answers … So how did it come to this—Bezos and Elon Musk, competitors in so many ways, working together in space? There are several answers. Most obviously, launching payloads for customers is one of SpaceX’s two core business areas, alongside Starlink. SpaceX sells launch services to all comers and typically offers the lowest price per kilogram to orbit. There’s immediate revenue to be made if a company with deep pockets like Amazon is willing to pay SpaceX. Second, the other options to get Kuiper satellites into orbit just aren’t available at the volume Amazon needs. Amazon has reserved the lion’s share of its Kuiper launches with SpaceX’s competitors: United Launch Alliance, Arianespace, and Jeff Bezos’ own space company Blue Origin. Lastly, SpaceX could gain some leverage by providing launch services to Amazon. In return for a launch, SpaceX has asked other companies with telecom satellites, such as OneWeb and Kepler Communications, to share spectrum rights to enable Starlink to expand into new markets.
Trump orders cull of commercial launch regulations. President Donald Trump signed an executive order on Wednesday directing government agencies to “eliminate or expedite” environmental reviews for commercial launch and reentry licenses, Ars reports. The FAA, part of the Department of Transportation, is responsible for granting the licenses after ensuring launch and reentries don’t endanger the public, comply with environmental laws, and comport with US national interests. The drive toward deregulation will be welcome news for companies like SpaceX, led by onetime Trump ally Elon Musk; SpaceX conducts nearly all of the commercial launches and reentries licensed by the FAA.
Deflecting scrutiny? … The executive order does several things, and not all of them will be as controversial as the potential elimination of environmental reviews. The order includes a clause directing the government to reevaluate, amend, or rescind a slate of launch-safety regulations written during the first Trump administration. The FAA published the new regulations, known as Part 450, in 2020, and they went into effect in 2021, but space companies have complained that they are too cumbersome and have slowed down the license approval process. The Biden administration established a committee last year to look at reforming the regulations in response to industry’s outcry. Another part of the order that will likely lack bipartisan support is a call for making the head of the FAA’s commercial spaceflight division a political appointee. This job has historically been held by a career civil servant.
Ariane 6 launches European weather satellite. Europe’s new Ariane 6 rocket successfully launched for a third time on Tuesday night, carrying a satellite into orbit for weather forecasting and climate monitoring, Euronews reports. “The success of this second commercial launch confirms the performance, reliability, and precision of Ariane 6,” said Martin Sion, CEO of ArianeGroup, operator of the rocket. “Once again, the new European heavy-lift launcher meets Europe’s needs, ensuring sovereign access to space,” Sion added. It marks the second commercial flight of the rocket, which has been in development for almost a decade with the European Space Agency (ESA). It is significant as it gives Europe independent access to space and reduces its reliance on Elon Musk’s SpaceX.
Eumetsat returns to Europe … The polar-orbiting weather satellite launched by the Ariane 6 rocket this week is owned by the European Organization for the Exploitation of Meteorological Satellites, or Eumetsat. Headquartered in Germany, Eumetsat is a multinational organization that owns and operates geostationary and polar-orbiting weather satellites, watching real-time storm development over Europe and Africa, while feeding key data into global weather and climate models. Just last month, Eumetsat’s newest geostationary weather satellite launched from Florida on a SpaceX Falcon 9 rocket because of delays with the Ariane 6 program.
Rocket Lab isn’t giving up on 2025 yet. Rocket Lab continues to push for a first launch of its medium-lift Neutron rocket before the end of the year, but company executives acknowledge that schedule has no margin for error, Space News reports. It may seem unlikely, but Rocket Lab’s founder and CEO, Peter Beck, said in a conference call with investment analysts last week that the company has a “green light” schedule to debut the Neutron rocket within the next four-and-a-half months. There’s still much work to do to prepare for the first launch, and the inaugural flight seems almost certain to slip into 2026.
Launch pad nearly complete … Rocket Lab plans to host a ribbon-cutting at the Neutron rocket’s new launch pad on Wallops Island, Virginia, on August 28. This launch pad is located just south of the spaceport’s largest existing launch facility, where Northrop Grumman’s Antares rocket lifts off on resupply missions to the International Space Station. Rocket Lab has a small launch pad for its light-class Electron launcher co-located with the Antares pad at Wallops.
Chinese company reveals drone ship. The Chinese launch company iSpace has released the first photos of an ocean-going recovery ship to support the landings of reusable first-stage boosters. The company hosted a dedication ceremony in Yangzhou, China, earlier this month for the vessel, which looks similar to SpaceX’s rocket landing drone ships. In a press release, iSpace said the ship, named “Interstellar Return,” is China’s first marine rocket recovery ship, and the fifth such vessel in the world. SpaceX has three drone ships in its fleet for the Falcon 9 rocket, and Blue Origin has one for the New Glenn booster.
Rocket agnostic … The recovery ship will be compatible with various medium- and large-sized reusable rockets, iSpace said. But its main use will be as the landing site for the first stage booster for iSpace’s own Hyperbola 3 rocket, a medium-lift launcher with methane-fueled engines. The company has completed multiple vertical takeoff and landing tests of prototype boosters for the Hyperbola 3. The recovery ship measures about 100 meters long and 42 meters wide, with a displacement of 17,000 metric tons, and it has the ability to perform “intelligent unmanned operations” thanks to a dynamic positioning system, according to iSpace.
Vulcan’s first national security launch. United Launch Alliance delivered multiple US military satellites into a high-altitude orbit after a prime-time launch Tuesday night, marking an important transition from development to operations for the company’s new Vulcan rocket, Ars reports. This mission, officially designated USSF-106 by the US Space Force, was the first flight of ULA’s Vulcan rocket to carry national security payloads. Two test flights of the Vulcan rocket last year gave military officials enough confidence to certify it for launching the Pentagon’s medium-to-large space missions.
Secrecy in the fairing … The Vulcan rocket’s Centaur upper stage released its payloads into geosynchronous orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator roughly seven hours after liftoff. One of the satellites deployed by the Vulcan rocket is an experimental navigation testbed named NTS-3. It will demonstrate new technologies that could be used on future GPS navigation satellites. But the Space Force declined to disclose any information about the mission’s other payloads.
Artemis II crew trains for nighttime ops. The four astronauts training to fly around the Moon on NASA’s Artemis II mission next year have been at Kennedy Space Center in Florida this week. One of the reasons they were at Kennedy was to run through a rehearsal for what it will be like to work at the launch pad if the Artemis II mission ends up lifting off at night. Astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen put on their spacesuits and rehearsed emergency procedures at Launch Complex 39B, replicating a daytime simulation they participated in last year.
Moving forward … The astronauts also went inside the Vehicle Assembly Building to practice using egress baskets they would use to quickly escape the launch pad in the event of a prelaunch emergency. The baskets are fastened to the mobile launch tower inside the VAB, where technicians are assembling and testing the Space Launch System rocket for the Artemis II mission. Later this year, the astronauts will return to Kennedy for a two-part countdown demonstration test. First, the crew members will board their Orion spacecraft once it’s stacked atop the SLS rocket inside the VAB. Then, in part two, the astronauts will again rehearse emergency evacuation procedures once the rocket rolls to the launch pad.
China’s Long March 5B flies again. China is ramping up construction of its national satellite-Internet megaconstellation with the successful deployment of another batch of Guowang satellites by a heavy-lift Long March 5B rocket on Wednesday, Space.com reports. Guowang, whose name translates as “national network,” will be operated by China SatNet, a state-run company established in 2021. The constellation will eventually consist of about 13,000 satellites if all goes to plan.
Make this make sense … Guowang is a long way from that goal. Wednesday’s launch was the eighth overall for the network, but it was the fourth for the project in less than three weeks. Each mission lofts just five to 10 Guowang spacecraft, apparently because each satellite is quite large. For comparison, SpaceX launches 24 to 28 satellites on each mission to assemble its Starlink broadband megaconstellation, which currently consists of nearly 8,100 operational spacecraft. The Long March 5B is China’s most powerful operational rocket, with a lift capacity somewhat higher than SpaceX’s Falcon 9 but below that of the Falcon Heavy. It begs the question of just how big the Guowang satellites really are, and do they have a purpose beyond broadband Internet service?
