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.
