Rocket Report: Rebuild begins at Blue Origin launch pad; Relativity targets Mars
A French launch startup is scrapping the name of its rocket, apparently due to a trademark issue.
Welcome to Edition 8.46 of the Rocket Report! We don’t mention Starship in the body of this week’s report, so I’ll give a brief update here. The next test flight of SpaceX’s mega-rocket—Flight 13—could happen as soon as next month, according to Gwynne Shotwell, the company’s president and chief operating officer, in a recent interview with CNBC. There’s still a fair bit of work to go before Flight 13, so don’t count on a launch next month just yet. What we do know, based on Shotwell’s comments to CNBC, is the next Starship test flight will look a like like the previous one last month, with a suborbital flight path and a splashdown of the ship in the Indian Ocean. SpaceX is holding off on an orbital flight until at least the following launch, Flight 14, after the ship was unable to complete a critical engine restart in space on the last flight.

Isar test flight scrubbed again. Isar Aerospace still commands top position among a new generation of European rocket startups, but the company’s efforts to launch a critical test flight of its Spectrum rocket continue to encounter roadblocks, Ars reports. The latest delay came Monday, when Isar scrubbed a launch attempt after “detecting off nominal behavior in the vehicle’s fluid systems,” according to a social media post. “The teams are analyzing the new data to isolate the root cause.” Isar is flush with cash, having raised nearly $1 billion to date, but is still lacking in the critical currently of flight experience. The Spectrum rocket has flown just once to date, on a failed launch last year that lasted less than 30 seconds.
Gravity still winning… The two-stage, 92-foot-tall (28-meter) Spectrum rocket was awaiting liftoff from Andøya Spaceport in northern Norway. It was the fourth time in five months that Isar Aerospace, headquartered near Munich, Germany, had reached a target launch date for the second test flight of the Spectrum launch vehicle. Isar called off a launch attempt on January 21 due to an issue with a pressurization valve, and then halted a countdown on March 25, moments before liftoff, when engineers detected rising temperatures in the rocket’s liquid propane fuel. Isar officials attributed the problem to a delay earlier in the countdown caused by an unauthorized boat in restricted waters along the rocket’s flight path. Managers stood down from another launch attempt on April 9 to evaluate a suspected leak in a composite overwrapped pressure vessel.
Swift reboost mission ready for launch. Just 10 months ago, NASA asked three companies if they could do something nobody had done before. Could they build and launch a satellite to save a $500 million astronomy mission at risk of crashing back to Earth? What’s more, could they do it in less than a year on a tight budget? The company that came back to NASA with the most compelling solution was a startup named Katalyst Space Technologies, and they have already given the agency a satisfying answer, Ars reports. Katalyst’s reboost satellite, named Link, was built in less than a year and is now integrated with an air-launched Northrop Grumman Pegasus XL rocket for a ride to space slated for no earlier than June 27.
More steps to go… The speed of development of the robotic mission to rescue NASA’s Swift observatory has been remarkable. Now, the mission needs to work. “To be honest, no one thought it was going to be possible. No one thought we would get as far as we’ve already gotten today,” said Shawn Domagal-Goldman, director of NASA’s astrophysics program. “And I have to be honest, there are stil
