    Amazing to see how well it manoeuvres and fires the engines at the last minute to land successfully!

    Speculation is methane leak from hard landing

    If only there were some proven, reusable, easily landable spacecraft which wasn't a rocket

    That landing was fucking amazing - okay, so it blew up 8 minutes later but at this early prototyping phase what has been achieved so far with the prototypes in such a short space of time is absolutely incredible.

    All is good - the initial lift off, the stable ascent, the engine cutoffs, the horizontal belly-flop, absolutely nailing the trajectory to the landing pad, the flip to vertical for landing and now, finally, a landing. Not a PERFECT landing of course, there were obviously problems with the landing legs and the speed of descent which was a tad too fast, but still, it LANDED in one piece! And this has all been done with a newly designed Starship AND newly designed engines which are all still prototypes.

    Oh, and finally, a big FUCK YOU to the absolute cunts in the media who still concentrate on the later explosion rather that highlighting how well Starship has done after just three test flights.

    That was amazing however I'm not sure how comfortable a free fall landing will be for passengers!

    Problem with shuttles is their stubby wings need air to land on, so they donít work on the moon or mars.

    It's a beast to watch.

    My takeaway is if you are 'lucky' enough to be a passenger on one of these things, make sure you get off it within 14 minutes of landing... ;)

    Just read the BBC article about it exploding, watched the embedded video of the flight, it landed, the commentator started saying "Third time's a charm... " and went through all the rocket's manoeuvres in a celebratory tone...

    ... then they didn't even show the explosion, despite it being mentioned in the article headline!

    I was gleefully waiting for it to explode to make the commentator look ridiculous.

    Why do I get the impression SpaceX are always trying to cover things up to safeguard their share price?

    This is my sole concern with the design, it's that flip to vertical at a pretty low height which then relies on the engines firing up correctly; even once they appear to have it nailed on I'd still be nervous. Musk has said that he wants there to be hundreds of Starship flights before people are allowed on board - that's great but even when it appears to be working perfectly there is still no room at all for error.

    There doesn't seem to be an easy way around it either because it's all down to saving weight on fuel - the belly flop descent is designed to increase drag and slow down the Starship (it's a lot heavier than the Falcon 9 so a vertical unpowered descent would be too fast), but then the Starship needs to flip to vertical at a height of about 1km for landing. If two out of three engines fail (two are needed for the flip) or there's an issue with the fuel supply then the Starship is toast.

    I believe that later iterations will eventually have hot gas thrusters to assist with the flip so hopefully that will make the manoeuvre more reliable too.

    TBF the SpaceX feed ended shortly after landing. I saw the explosion on the NASA one.

    The whole point of the SpaceX coverage is to show take-off and landing which is exactly what they did, they didn't expect it to explode EIGHT MINUTES after a pretty successful landing. There's no 'cover up' here.

    Exactly. They're not hiding anything. In fact they're extremely open and accessible, even allowing various space enthusiasts to live stream the Starship (and booster) assembly area and the launch and landing area pad 24/7. Check out, for example, LabPadre's live channels on YouTube and NasaSpaceFlight's channel for daily updates showing all kinds of ongoing assembly work on Starships, the boosters, the construction work on the launch and landing area, deliveries of parts (including Raptor engines), etc, etc, etc.

    And just this morning they flew another starlink mission, 75th successful landing and the 8th flight and landing of that particular booster.

    I really like the video comments on that Space X rocket explosion compilation:

    "That's not an explosion... it's just rapid unscheduled disassembly" :D

    Crazy that all these rockets crash. Why don't they just use the shit they used in the 60s for that definitely real moon landing.

    There's a Curious Droid video just on this topic.

    Basically, Nasa still has the plans, but not the technical know-how to build them anymore.

    Yeah, all of those fully reusable rockets which did numerous flights ...... oh, hang on.

    Even the shuttle doesn't really count (besides the fact that was mostly the 80s) because the main fuel tank and SRBs were never reused.

    Starship is the first fully reusable space vehicle (Falcon 9 mostly is, the only 'waste' part is the second stage which carries the payload into orbit).

    I have to correct you there Rob, the SRBs were reused, they landed in the water under parachutes.

    I stand corrected. :) I knew they were recovered for inspection but wasn't aware (or had forgotten) that they were reused.

    The main fuel tank burned up in the atmosphere though.

    The most important thing is each time they do this stuff they make some progress and learn new information.

    If you look at the thing as it landed there was already a fire on one side. You can see the yellow flame.

    You're right ofc - its 14:30 into mission time - sorry!

    I blame staying up late to watch rockets explode :)

    I wasn't sure if that was just the end of the afterburner (or whatever the rocket uses) to slow its descent
