Starship | SN15 | High-Altitude Flight Test

As early as Wednesday, May 5, the SpaceX team will attempt a high-altitude flight test of Starship serial number 15 (SN15) – our fifth high-altitude flight test of a Starship prototype from Starbase in Texas. SN15 has vehicle improvements across structures, avionics and software, and the engines that will allow more speed and efficiency throughout production and flight: specifically, a new enhanced avionics suite, updated propellant architecture in the aft skirt, and a new Raptor engine design and configuration.

Similar to previous high-altitude flight tests of Starship, SN15 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. SN15 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. SN15’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 fifth high-altitude flight test of Starship!

    Historic moment for all humans! great work by the Spacex team!

      @PHeMoX This isnt playing catching up at all, they perfected the booster landing, and while Ibdo think Mcdonnel Douglas had potential from their first landing you gotta guve credit where credit is due, this is a huge acomplishmant. The rocket will take humans around the moon in 2023, go to Mars, originally was going to be NASA’s Human Landing System until they cancelled it due to Blue Origin and Dynetics protesting. We’ll see what happens to that

      Why there was frost on the tip and the belly of starship?

      @PHeMoX ok twitter folks

    • morry19965 says:

      @Sharda Pareek The fuels are cryogenic …extremely cold ..hence the frost

      @Ндоско Эбльап ну для тебя ведь не понять дурашка ты из СНГ, что эти взрывы специально сделаны для опытов, как поведёт себя техника)))

    1950’s sci-fi brought to life. I’m expecting Flash Gordon to step out on landing.

    I watched this live in the UK with my 6 year old son and can safely say that Space X are inspiring minds and helping create the engineers, designers and forward thinkers of the future by releasing live moments of history like this for all to see. Thank you.

    They tried and failed several times before. I remember some people laughed at them. They never gave up! They kept trying and finally succeeded.

    • burddur plays pc says:

      @Wilfred Darr Landing a rocket is like landing a pen right side up from the top of a water tower. Extremely difficult, but not impossible. Next up, we have to land a sausage link from the same height, aka super heavy! lol

      Honestly if you are an engineer worth your salt — which all of SpaceX engineers arguably are — what some randos are saying in the press doesn’t do anything for you. Rockets don’t fly on criticism or praise, they fly because they are made to. Meaning that SpaceX knew what they wanted when they designed the Starship. Sure, a lot of it isn’t a sure bet, but the point is by the time they started buying and rolling stainless steel and attaching Raptor engines to test this, they already knew they’re going to Mars one day and that Starship is going to fly as long as they get to test and refine their fundamental technology. Of course, not all companies work like that — there are plenty who say they will revolutionize some industry with their disrupting product, but a month later they go bankrupt for failing to get any funding from anybody, or worse, are exposed for running their mouth too much. SpaceX, on the contrary, don’t promise for sheer shock value, they have ambitions and the means to realize them. Musk is usually humble, too, if you are around his Twitter, for example. There lies the difference. And like I said, they couldn’t care less if everyone on the planet said Musk or his engineers are idiots. It’s money that employs them, not words. And SpaceX isn’t even public, so there. If it was, or if you got NASA to not give SpaceX any more contracts, Musk wouldn’t have liked that, but they couldn’t care less for the laughing people, honestly.

      All this will be ditched for a new Space shuttle. Just wait and see. Even he succeed in his attempt, this will prove it self useless.

      Even with those tiny prototype landing legs xD

    I feel blessed and happy that I’m born in the era of Elon Musk and spaceX…

    • Michael Salaño says:

      @J. Gaulke dud easy we dont want that to happen, if that actually happen where doom it’s end of every think.

    • Adam Marcinkowski says:

      You are so lame ! , Elon Musk did nothing special !

    • SotirzvaniDjubre says:

      @Sci Fi Games Looks like a pioneer job, because probably it is. But only in some aspects. What it actually does is to fly up and land. Never seen before? Take time and space to elaborate, and YT is not a place for that. Not all ingenious inventions are practical or helpful. I even think that Tesla as a car do not have a future too bright. That doesn’t mean Musk as a businessmen will fail. Future of the space flight is probably in something that will take off like a plane. All that Musk did here is to cut some of the expense in the process by spending millions.

    • Traveller says:

      @SotirzvaniDjubre i still don’t see how this is a waste on money

      Can you explain your points with evidence and facts?

    • Traveller says:

      @SotirzvaniDjubre also you can’t fly an airplane to space

    Им повезло,что рогозина у них нет.

    There is literally nothing cooler on this planet than the fact that we can not only do this, but we can just log into youtube and watch it. no big deal. Absolutely amazing.
