That is some deep science!

Thanks!

Well, if you want science. There is no heat in the vacuum of space. Any charring of a spacecraft happened upon reentry.   Every reentry has the same amount of burning and charring no matter where the spacecraft traveled to before it returned.

A return from Mars takes longer to return that's all.

The surface gravity on Mars is only about 38% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mars, so the boost from Mars is not anything near what we see on a liftoff from the Earth.
