Even if it does go to Mars there are some major warts on the design. When you land you're 35-40 meters or so up in the air so there's a whole other elevator assembly needed just to get people out of the rocket to the ground.
We've been hoisting people and cargo up/down with pulleys and cables for thousands of years. This seems like the smallest obstacle Starship has to face.
We’ve been opening and closing doors for even longer and yet it has still posed a challenge for SpaceX when dealing with the payload door on Starship. Space makes even trivial things hard.
Sure. But they gotta fix the door, either way.
Winching stuff out of said open door seems like a much, much easier task.
The satellite door is completely different from what they'll need for MarsShip, that's even larger and has to function as an airlock. None of what they're trying to do now matters for the Mars door.
That's a lot of certainty for something that hasn't even been designed yet.
The outside door needn't be part of the airlock. It's certainly big enough to have an internal airlock leading to depressurized internal space.
The things that make a door that tests fine on Earth break in orbit are likely to be things that need fixing for a similar door on Mars. They won't be all the same challenges, but some will absolutely be shared.
What viable alternative design would not have this constraint?
A smaller purpose build lander that doesn't need the fuel capacity for the entire journey would be significantly shorter and could be wider too. That would get it significantly closer. Enough that a simple ladder would be viable so they aren't reliant on a winch/elevator.
So you're suggesting something similar to the Apollo LEM that will land, and carry enough fuel to return to orbit to dock with something that will contain enough fuel that will return to Earth?
Wouldn't that make the mission unfeasible because it requires ISRU of return fuel?
The Starship version of the Mars mission also requires ISRU. At least that's what was presented.
