SpaceX Launches Massive Starship On Its Sixth Test Flight (space.com) 103

SpaceX's Starship rocket successfully completed its sixth launch today. Not only did it carry the first-ever payload but it also briefly re-lit one of its six Raptor engines about 38 minutes into flight, a crucial milestone for future space missions. Space Magazine reports: SpaceX landed Starship's huge first-stage booster, known as Super Heavy, back at the launch tower on the vehicle's most recent flight, which occurred on Oct. 13. The company aimed to repeat that feat -- which the tower achieved with its "chopstick" arms -- today, but the flight data didn't support an attempt. "We tripped a commit criteria," SpaceX's Dan Huot said during the company's Flight 6 webcast. So Super Heavy ended up coming down for a controlled splashdown in the Gulf of Mexico instead, hitting the waves seven minutes after liftoff.

Today's mission aimed to do far more than just bring Super Heavy back to Earth in one piece. SpaceX also wanted to put Starship's upper stage -- a 165-foot-tall (50 m) spacecraft called Starship, or simply "Ship" -- through its paces. The launch sent Ship on the same semi-orbital trajectory that it took on Flight 5, targeting a splashdown in the Indian Ocean off the northwestern coast of Australia about 65 minutes after liftoff. But Ship also achieved some new milestones along the way this time. For example, Flight 6 carried the first-ever Starship payload -- a plush banana onboard Ship, which served as a zero-gravity indicator. (It was not deployed into space.) In addition, Ship briefly re-lit one of its six Raptor engines about 38 minutes into the flight. (Super Heavy also employs Raptors -- a whopping 33 of them.)

This burn helped show that Ship can perform the maneuvers needed to come back to Earth safely during orbital missions. Indeed, Ship is designed to be fully and rapidly reusable, just like Super Heavy; SpaceX eventually intends to catch it with the chopstick arms as well, and will likely try to do so on a test flight in the near future. Flight 6 also tested modifications to Ship's heat shield, which protects the vehicle during reentry to Earth's atmosphere.

    Tower appears to have some damage the precludes the attempt, the rest of the test regime seem to have gone well. They executed the in orbit relite of raptor engine in low gravity environment, successfully executed the reentry with a significant amount of reduction of heat shielding tiles and we got some very useful data. Unfortunately the lone cargo (1 banana) was lost along with the ship.

      I was curious as to why they did not attempt the catch. Thank You for the info :)

        A damaged telemetry antenna on top of the Launch tower that (presumably) provides data for the catch system. You could see that it was bent partially over.

      The raptor engine is the real star for me. They appear to have had all engines work flawlessly throughout the entire test. Given that there are 39 engines on each stack, it's rapidly gaining some very impressive reliability figures. With an engine that is performing that well, bizarrely, the things like flipping and landing are not that difficult from a controls perspective - high control authority is the key to making control systems simple, though I guess there is a bit of 'seat of the pants' due to the limited propellent available to manoeuvre.

      Raptor V3 looks very impressive, and they are still boosting the thrust numbers on it. I can see why they want to fish them out of the ocean - China/Russia/Bezos etc would love to get their hands on an engine.

    • Tower appears to have some damage the precludes the attempt,

      Are you saying they land at the same tower they took off from?

      The takeoff and landing towers do such different jobs it just didn't occur to me they might be the same.

    I enjoy hearing about SpaceX's progress. I'm not sure why the peanut gallery has to turn every step of SpaceX's journey into another chance to rant about political bullshit that has little to nothing to do with SpaceX other than it may tangentially relate to the company mouthpiece, but this is the type of story I actually appreciate coming up on Slashdot.

    If only all the people whining about how political everything is could set aside their own need to bitch about politics on literally every single story. Musk may not be perfect, but SpaceX is impressive regardless of who may be involved in their success. Aren't we all tired of having to pretend that the world is a perfect place if not for Elon Musk? Good grief.

      Musk is extremely political and leverages his business success for political objectives, so I think it's fair game. I'm not going to stand around here and pump up his balloon just so he can then use that prestige to subject my friend to Russification.

      But when /. does put up a SpaceX article it might be wise to put up another Musky article to give people somewhere to vent. I do have a strong urge to punch Musk in his non-figurative face for all the crap he's pulling and it would be nice if /. didn't seem to

        While it would further politicize Slashdot in general, I can see honeypotting shit-stirring Musk articles surrounding SpaceX or Tesla articles being a good filter move.

    • Complaining about something being 'political' is often shorthand for saying it doesn't affect you, but not everyone has that luxury. In my case, as a trans woman, I can't help but notice that he donated $50,000,000 to a PAC in 2022 that ran anti-transgender attack ads, nor that he spent $100,000,000 in 2024 supporting Donald Trump's presidential campaign (with total spending on anti-transgender attacks surpassing $200,000,000).

  • This is their sixth flight and they haven't even reached orbit yet.

    The third flight of the Saturn V fifty six years ago took three men to the moon.

    • by BranMan ( 29917 )

      Um... No. Apollo 7 was the first flight to be manned. And that sure didn't go anywhere near the moon. There were quite a number of unmanned flights before that as well.

      Apollo 10 flew men around the moon for the first time. Was certainly NOT the third flight of the Saturn V.

    • The Saturn V was a huge achievement, especially for its time, and a credit to the engineers who flew it so successfully despite its many issues. It could lift an impressive 140 tons to LEO. But it was also ~$1.5 billion per launch in today's dollars, and that all got tossed in the sea every time.

      Starship is much more capable, around twice as powerful, yet is a fraction the cost at ~$100M to build and launch. It can lift around 230 tons to LEO when fully expended, so it is more than capable right now of loft
