Welcome to Edition 7.45 of the Rocket Report! Let's talk about spaceplanes. Since the Space Shuttle, spaceplanes have, at best, been a niche part of the space transportation business. The US Air Force's uncrewed X-37B and a similar vehicle operated by China's military are the only spaceplanes to reach orbit since the last shuttle flight in 2011, and both require a lift from a conventional rocket. Virgin Galactic's suborbital space tourism platform is also a spaceplane of sorts. A generation or two ago, one of the chief arguments in favor of spaceplanes was that they were easier to recover and reuse. Today, SpaceX routinely reuses capsules and rockets that look much more like conventional space vehicles than the winged designs of yesteryear. Spaceplanes are undeniably alluring in appearance, but they have the drawback of carrying extra weight (wings) into space that won't be used until the final minutes of a mission. So, do they have a future?

One of China's commercial rockets returns to flight. The Kinetica-1 rocket launched Wednesday for the first time since a failure doomed its previous attempt to reach orbit in December, according to the vehicle's developer and operator, CAS Space. The Kinetica-1 is one of several small Chinese solid-fueled launch vehicles managed by a commercial company, although with strict government oversight and support. CAS Space, a spinoff of the Chinese Academy of Sciences, said its Kinetica-1 rocket deployed multiple payloads with "excellent orbit insertion accuracy." This was the seventh flight of a Kinetica-1 rocket since its debut in 2022.

In recent written testimony to a US House of Representatives subcommittee that oversees the military, the senior official responsible for purchasing launches for national security missions blistered one of the country's two primary rocket providers.

The remarks from Major General Stephen G. Purdy, acting assistant secretary of the Air Force for Space Acquisition and Integration, concerned United Launch Alliance and its long-delayed development of the large Vulcan rocket.

"The ULA Vulcan program has performed unsatisfactorily this past year," Purdy said in written testimony during a May 14 hearing before the House Armed Services Committee's Subcommittee on Strategic Forces. This portion of his testimony did not come up during the hearing, and it has not been reported publicly to date.

The Federal Aviation Administration gave the green light Thursday for SpaceX to launch the next test flight of its Starship mega-rocket as soon as next week, following two consecutive failures earlier this year.

The failures set back SpaceX's Starship program by several months. The company aims to get the rocket's development back on track with the upcoming launch, Starship's ninth full-scale test flight since its debut in April 2023. Starship is central to SpaceX's long-held ambition to send humans to Mars and is the vehicle NASA has selected to land astronauts on the Moon under the umbrella of the government's Artemis program.

In a statement Thursday, the FAA said SpaceX is authorized to launch the next Starship test flight, known as Flight 9, after finding the company "meets all of the rigorous safety, environmental and other licensing requirements."

A US-based propulsion company, Venus Aerospace, said Wednesday it had completed a short flight test of its rotating detonation rocket engine at Spaceport America in New Mexico.

The company's chief executive and co-founder, Sassie Duggleby, characterized the flight as "historic." It is believed to be the first US-based flight test of an idea that has been discussed academically for decades, a rotating detonation rocket engine. The concept has previously been tested in a handful of other countries, but never with a high-thrust engine.

"By proving this engine works beyond the lab, Venus brings the world closer to a future where hypersonic travel—traversing the globe in under two hours—becomes possible," Duggleby told Ars.

Gilmour Space, a venture-backed startup based in Australia, is about to launch a small rocket from its privately owned spaceport on a remote stretch of the country's northeastern coastline.

It's the first time anyone has attempted to reach orbit with a rocket designed and built in Australia. Gilmour's three-stage rocket, named Eris, could launch at any time during a 10-hour window Thursday, local time. In the United States, the launch window runs from 5:30 pm EDT Wednesday until 3:30 am EDT Thursday.

The debut launch of Gilmour's Eris rocket is purely a test flight. Gilmour has tested the rocket's engines and rehearsed the countdown last year, loading propellant and getting within 10 seconds of launch. But Gilmour cautioned in a post on LinkedIn early Wednesday that "test launches are complex." Gilmour added on social media that "weather, systems checks, or technical issues may delay the flight—sometimes by hours, days, or longer."

SpaceX fired six Raptor engines on the company's next Starship rocket Monday, clearing a major hurdle on the path to launch later this month on a high-stakes test flight to get the private rocket program back on track.

Starship ignited its Raptor engines Monday morning on a test stand near SpaceX's Starbase launch facility in South Texas. The engine ran for approximately 60 seconds, and SpaceX confirmed the test-firing in a post on X : "Starship completed a long duration six-engine static fire and is undergoing final preparations for the ninth flight test."

SpaceX hasn't officially announced a target launch date, but maritime warnings along Starship's flight path over the Gulf of Mexico suggest the launch might happen as soon as next Wednesday, May 21. The launch window would open at 6:30 pm local time (7:30 pm EDT; 23:30 UTC). If everything goes according to plan, Starship is expected to soar into space and fly halfway around the world, targeting a reentry and controlled splashdown into the Indian Ocean.

The White House Office of Management and Budget dropped its "skinny" budget proposal for the federal government earlier this month, and the headline news for the US space program was the cancellation of three major programs: the Space Launch System rocket, Orion spacecraft, and Lunar Gateway.

Opinions across the space community vary widely about the utility of these programs—one friend in the industry predicted a future without them to be so dire that Artemis III would be the last US human spaceflight of our lifetimes. But there can be no question that if such changes are made they would mark the most radical remaking of NASA in two decades.

This report, based on interviews with multiple sources inside and out of the Trump administration, seeks to explain what the White House is trying to do with Moon and Mars exploration, what this means for NASA and US spaceflight, and whether it could succeed.

Isar Aerospace, a German startup founded seven years ago, is positioned to become the first in a new generation of European launch companies to reach orbit with a privately funded rocket.

The company announced Friday that the first stage of its Spectrum rocket recently completed a 30-second test-firing on a launch pad in the northernmost reaches of mainland Europe. The nine-engine booster ignited on a launch pad at Andøya Spaceport in Norway on February 14.

The milestone follows a similar test-firing of the Spectrum rocket's second stage last year. With these two accomplishments, Isar Aerospace says its launch vehicle is qualified for flight.

Welcome to Edition 7.32 of the Rocket Report! It's true that the US space program has always been political. Domestic and global politics have driven nearly all of the US government's decisions on major space issues, most notably President John F. Kennedy's challenge to land astronauts on the Moon amid intense Cold War competition with the Soviet Union. The Nixon administration's decision to end the Apollo program and focus on building a reusable Space Shuttle was a political move. More than 30 years later, the Clinton administration ordered a reevaluation NASA's plans for a massive space station in low-Earth orbit. In the post-Cold War zeitgeist of the 1990s, this resulted in Russia's inclusion on the International Space Station program. Flawed or not, these decisions were backstopped with some level of reasoning, debate, and national consensus-building. Today, the politics of space seem personal, small, and mean-spirited . Thankfully, there's a lot of launch action next week that might thrust us out of the abyss, even just for a moment.

Rocket Lab launches for the 60th time. It's safe to say Rocket Lab is an established player in the launch business. The company launched its 60th Electron rocket Tuesday from New Zealand, Space News reports . It was the second Electron launch of the year, coming just 10 days after Rocket Lab's previous mission. The payload was a new-generation small electro-optical reconnaissance satellite for BlackSky. Rocket Lab has not disclosed a projected number of Electron launches for the year beyond estimating it will be more than the 16 Electron missions in 2024. The company said on its launch webcast that the next Electron launch was planned from New Zealand in "a few short weeks."
