Why SpaceX Starship’s Heatshield new design is more important than you think!

To gently land a rocket ship on the surface of Mars one must break the most ornery physics.
When a spacecraft returns to Earth, the relatively thick atmosphere helps slow down that speeding bullet. But on Mars, the aerodynamics are not so friendly. The atmosphere is much thinner, with the densest Martian air only about as thick as what you’ll find on Earth at 100,000 feet above sea level, more than three times the altitude of Mount Everest’s peak.
Of over 40 missions sent to Mars, fewer than half have been successful, according to NASA.
And now, Elon Musk wants to send people there?
“I call it the anti-Goldilocks atmosphere,” said Jim Reuter, NASA associate administrator for the space technology mission directorate. “It’s thick enough that it causes you problems and not thin enough to help you.”
So, the Starship won’t ever reach Mars intact? What about a hundred crew missions?

  1. Some kind of paragliding set up, not real certain how it would really work, less of an idea how it would deploy, need someway to slow down with out a parachute or rockets, best solution my high school graduate brain can come up with.

  2. You literally talked about nothing new and used a bunch of b-roll footage ripped from other youtubers. You title is misleading just for the clicks, shame.

  3. It seems increasingly evident that Musk's Mars ambitions are simple vapourware. If he was serious, and it wasn't just fund-raising spin, wouldn't SpaceX build their systems on the moon, without Nasa, first?
    You could show construction, power, habitation, multiple vehicles and refuelling within a recoverable range.
    Prove the concept locally, then Mars.

  4. Yes it's a great accomplishment for the tiles to make it through the test ! ? Will they make it back into the atmosphere where they need to maneuver to land ? What I mean is will the system's needed to Land survey to do there job when needed even if they lose some tiles ? That's the rite ?

  5. I have a question…metal expands and contracts depending on the temperature it is exposed to…would that mean when the starship re-enters the atmosphere…it will expand causing gaps between the tiles? Conversely, when it reaches the upper atmosphere and eventually leaves the atmosphere, will the metal contract to the point where tiles pop off or crack being crushed?

  6. I'm not worried about the heat shields I'm worried about the seams around the flaps.

  7. Hi alpha tech that was a great 👍 video update of star ship thanks 🙏 again David 🌍🚀🇬🇧❤️🙏👍

  8. An interesting test-bed for the TPS would be to attach some of the tiles to critical areas of the Orbital Launch Mount. (Stage Zero)

  9. Why does no one ever mention the thermal conductivity of aluminum vs stainless steel? Even though SS has a higher melting point, burn through of a missing tile will be quicker with SS – guaranteed.
    Take two comparable pieces of each and apply the same torch to them. The SS will become incandescent quicker and burn a hole before aluminum.
    Doubt it? Ask any welder why it’s easier to weld SS than aluminum.

  10. Starship will need good and well fixed heat shields, since, stainless steal will be likely more vibrate than thick aluminium (that's why some heat shields are fall off even just during test too..(think it how vibration will be the starship wall during reentry)..

  11. When falling though the atmosphere. More tiles is probably a better option than less 😂😉

  12. Thought provoking. I can’t help but think that no one would have ever designed a dedicated Mars lander in the long shape of Starship but rather all have been conical aeroshells. To me this is another example of inefficiencies resulting from trying to make one design do everything. A conical design minimizes the area that needs heat protection. For the same mass as the Starship I would bet that a conical shape could do away with the tiles entirely and spread the heating over such a large area that stainless steel would do thee trick.

  13. Transpiration? I thought the transpiration system was dropped a couple of years ago. Are you sure about this?

  14. Once Starship is ready for human flights they should embed a dragon capsule in the very top of the craft as an emergency exit spacecraft. That would be pretty neat 😃👍

  15. ♥️𝗧𝗿𝗲𝗻𝗱𝗶𝗻𝗴 𝗮𝗱𝘂𝗹𝘁 𝗽𝗼𝗿𝗻 𝘃𝗶𝗱𝗲𝗼𝘀 𝗼𝗻𝗹𝘆❤️ Alles sehr schön. Aber zuerst zusammen die Nummern 10 und 1. Eine empr.ONLINE Brünette und eine andere Blondine. Es wäre unfairf, wenn ich 4 wählen würde
