SpaceX Starship Landing on Mars needs bigger header tanks! #Shorts



Today we are talking about the SpaceX Starship Mars landing. Will this work? SpaceX’s colossal Starship hurtling through the super thin Martian atmosphere and trying to slow enough to flip over and touch down successfully with the available propellant? It is a good question and one I’ve been curious about for quite some time.

  1. you start atmosphere deceleration soon. If on earth say 1000km lateral travel during reentry. For Mars your glide path should 4 to 5 times longer and adjust entry angle to optimize glide and lower gravity Earth size tanks will be just fine

  2. I was in the impression that those header tanks are mainly needed to ignite the engines during the transition because the fuel would be sloshing around during that time but once the transition is complete and the vehicle is decelerating vertically, the gravity and deceleration should push the fuel of the main tank all the way to the bottom. This means that technically, they only need the header thank for the transition and could switch to using the normal tanks for most of the descent assuming that they would transition earlier due to lower air friction. I would assume a landing burn on mars to last much longer then on earth.

  3. A great deal of Delta V will be achieved during the orbital entry burn. Much of the atmospheric density is offset by the fact that landing will take place in approximately 0.6 G., meaning not only is orbital velocity much lower, but also that thrust to weight ratio will be enhanced by 40%. Has All this been taken into account in your fuel requirement figures?

  4. The header tanks are used because of a zero or unoriented gravity position. Rockets need to get fuel into the engines and normally do this by thrusting forward creating g’s directed to the aft of the vehicle … pushing fuel towards the engines. The header tanks provide enough fuel to get reoriented and start a retro burn … but after that the normal tanks will provide fuel because the vehicle will become “g oriented”.

  5. If they can maintain enough propellants in the main tanks they could use the header tanks to just start the engines so the propellant wil flow back to the bottom of the main tanks. My question is: will a Martian Starship need larger flaps?

  6. Hey commentary guy. I'm trying to get a link to Elon Musk, but don't know how. Listen to this, there's a technology using Ions to propel vehicles. So maybe you become th Genius, to suit this to Elon Musk's think tank, & gain you a couple of Million $$$ for your Valiant effort. Pass it on to him.

  7. The header tanks aren't there to fuel the landing, there will still be fuel in the main tanks refueled in orbit. They make the initial thrust (starting the rocket) because the propelent in the main tank will be in free fall and the thrust is needed to get fuel to the intake. So I think you missed the mark on this one…..

  8. You just need to aero brake for longer in the thin atmosphere. The starship will not be dropping, it will be gliding at a high angle of attack causing lots of drag and slowly slowing down. This gliding trajectory will be designed so the starship reaches stall angle of attack at a suitable low altitude and low speed just short of the desired landing site. Whereupon the craft will flip and do the vertical landing descent.

  9. There is no reason to go to mars, mankind would benefit more if we first invest money, effort and develop the technology to ensure earth is habitable for as long as possible, colonization of mars is a marketing attention seeking effort by Elon Musk and space X

  10. Just a general gripe about vertical videos here. Please stop. don't become part of the TikTok mentality…..
    If you shoot in landscape I can enjoy on the big screen. if I'm watching on my phone I can spend the 0.000001 calories to rotate my phone one it's side and get the same pixels…

    If you shoot in portrait, I'm just screwed, as often you can't make it full screen on a mobile browser, rotating just makes is smaller. I lose 75% of my screen on the desktop, can't fast-forward/rewind, or even maximise the video.

    We have eyes to the side of each other, not one top of each other… we didn't evolve to operate that way.

  11. How can terminal velocity be four to five times more than earth when Mars is a smaller planet ?

  12. Hell, at this point might as well build a space ship with a large engineering bay and sail it to Mars. That way you can fill the rocket with what ever it needs on the surface.

  13. I don’t get it. The header tanks won’t be in the nose when they have payload there.
    I know these YouTubers try to make extra content, but it’s often so poorly thought through it’s unwatchable. I fucking hate it when amateurs force feeds us with their own bad take on things.

  14. This thing will likely never get to Mars. The Mars colony put out by Musk is a fantasy.

  15. Think about it a minute. If the atmosphere is too thin for aero braking then you’ll start the landing burn higher and faster. The header tanks will start the burn as normal, but as soon as the burn produces G-load on the ship, the header tanks aren’t needed anymore. It’s not doing a rapid flip maneuver at low altitudes where you need the engines to fire and produce thrust immediately. As long as there is a short period producing Gs, the fuel will rush to the engine feeds from the main tank.

  16. I can't help but think it would be a better idea to have different landers for different planets.
    The one size fits all thing doesn't do it for me when it comes to space travel.

  17. I will love to see what a cockpit of a starship will look like. I hope it's sleek and cool like in the dragon rockets but better.

  18. Finally Markus I commented this weeks ago I cant believe you did it! 😁😁

  19. Correct me if I'm wrong.
    Header tank position is temp as no other mass above the main tanks 4 now, as per SpaceX.
    The calculations u present Appear to ignore the use of Draco thrusters during landing/takeoff, Or am I missing something?

  20. Would use a propeellant tanker in a Mars orbit to avoid needing bigger header tanks , after the first couple of cargo tankers safely land they can be used to for orbital refueling.
