Starship | SN11 | High-Altitude Flight Test

Starship | SN11 | High-Altitude Flight Test

As early as Tuesday, March 30, the SpaceX team will attempt a high-altitude flight test of Starship serial number 11 (SN11) – our fourth high-altitude flight test of a Starship prototype from Starbase in Texas. Similar to previous high-altitude flight tests of Starship, SN11 will be powered through ascent by three Raptor engines, each shutting down in sequence prior to the vehicle reaching apogee – approximately 10 km in altitude. SN11 will perform a propellant transition to the internal header tanks, which hold landing propellant, before reorienting itself for reentry and a controlled aerodynamic descent.

The Starship prototype will descend under active aerodynamic control, accomplished by independent movement of two forward and two aft flaps on the vehicle. All four flaps are actuated by an onboard flight computer to control Starship’s attitude during flight and enable precise landing at the intended location. SN11’s Raptor engines will then reignite as the vehicle attempts a landing flip maneuver immediately before touching down on the landing pad adjacent to the launch mount.

A controlled aerodynamic descent with body flaps and vertical landing capability, combined with in-space refilling, are critical to landing Starship at destinations across the solar system where prepared surfaces or runways do not exist, and returning to Earth. This capability will enable a fully reusable transportation system designed to carry both crew and cargo on long-duration, interplanetary flights and help humanity return to the Moon, and travel to Mars and beyond.

Given the dynamic schedule of development testing, stay tuned to our social media channels for updates as we move toward SpaceX’s fourth high-altitude flight test of Starship!

    *SN8: Boom*
    *SN10:Land& Boom*
    *SN11:Didn’t see what happened and Boom💥💥💥*

    11:50 *donk*
    was it a landing donk, a pressure tank ponk, or a metal/mechanical bonk after successfully landing? doesn’t sound like an explosion at least. was this from an onboard mic? if so, that would suggest no explosion, right? because you would think an explosion results in no sound transmitting back to base at all from an onboard mic
    *edit: okay it blew up*

    “looks like we had another exciting test”

    thats why I love SpaceX. They have the right attitude with their flight tests.

      @Linecraftman Elon also tweeted they had engine problems but it wouldnt have affected the landing, I think this was a test to see if foggy launches would be a option in the future when Starship is fully operational like an airliner, how SpaceX intends for it

    • Daron Malakian's Fedora says:

      @Larry Potter *Prototyping* Havent heard of that word huh? It was still a success. Its a prototype test. Thats like when a prototype car crashes. You make no sense, they are still working on it

    • Claudi M. says:

      Attitude and a huge budget.

    • David Johnson says:

      @Alan The poster of the original comment in this thread. As well as the person covering the launch for SpaceX….

      “They have the attitude with their flight tests.”

      What are you talking about?? You can’t just say anything and have it magically make sense. This video is a flop and a waste of time.

    Humans: Shows the explosion, please
    Sn11: it’s impossible.
    Humans: No, It’s necessary.

    “Will it land? Will there be an RUD?”
    It’s already done both. We’re out of options.
    _SN11 goes _*_around_*_ the pad in the 4th dimension_

  6. Efloor says:

    I love the thought of being an old man walking through a museum and pass by pieces, maybe huge chunks from these SN test flights. Rest in pieces SN11, hope I see you soon.

    A successful person never fails. They either win or learn. Today is a learning day for SpaceX and that’s awesome!

    • Leo Gacitua says:

      @Richard 1 Yeah, crappy eye ball designing. Like when they tested the worlds largest upper stage 4 times in 4 months, and prior to that when they designed Falcon 9. You’re used to NASA working at a snails pace thanks to bureaucracy, whereas this right here is untethered engineering.

    • Richard 1 says:

      @Jadan Jenkins Another Elon fanboy with no real world experience.

    • Tim Montanus says:

      @Richard 1 what did you design

    • Jens Bruning says:

      @Colin Southern I know

    • Colin Southern says:

      @Richard 1 “I used to design this stuff” I’m calling BS on that – for a number of reasons:

      1. Someone who had would appreciate the process and wouldn’t make comments such as yours as a professional courtesy.

      2. Someone who had would appreciate that there’s a LOT more sophistication in the design process than “designing things by eye” and would – again – refrain from making comments such as yours because they would know just how much they DON’T know about the inner workings of SpaceX which – incidentally – is the same “Musk-hyped” company responsible for the phenomenally successful Dragon Cargo and Dragon Crew products (probably designed by many of the same engineers who are currently working on the Starship project).

      So I strongly suspect that the reality is that although neither one of us knows the first thing about Starship engineering, I’m at least smart enough to realise that. You on the other hand appear to be one of those people who find it easy to comment on anything … because you literally don’t know how much you don’t know. And if I’m wrong then perhaps you should stop wasting your time posting internet comments and go work for SpaceX where you can show them how it should be done …

    SN8: Greeny, Leaky, Faulty Landing
    SN9: Uncontrolled, Tilted, Too Hard and BAD RUD
    SN10: Good, Bouncy, BOOM after Landing
    SN11:Invisible, Destructible and BOOM (In mid air)!., 💣💥😑😑

    Exciting test indeed

    If this launch had a Rocket Lab name it would be “Landing, In Some Pieces”
