Orbital Base Jumping

[Tai]

The backstory to why I'm wondering this is a long story, which I'll share if people ask, but in short: I'm wondering the rough levels of DR/other advantages that'd be necessary to jump from orbit and survive re-entry with little to no ill effects. The drop afterwards and accurately landing are handled; I'm just unsure whether the re-entry itself would be plausible.

The two scenarios I'm looking at are

a) A pair of psychics in light spacesuits harnessed together, one providing the shielding and propulsion for re-entry, the other handling the landing after. How much DR would the shielder need to be able to provide, for roughly how long?

b) A TL9 battlesuit upgraded to the gills as the signature gear of a one-man-army type character - what DR would be necessary, and is it reasonable for it to be added onto such a suit? Also, would it be possible to 'add' ablative DR, or would it have to be built with it to begin with, thus meaning it'd only get one drop?


If I'm looking at it the entire wrong way with DR and there's another, better way to model being able to survive reentry, then please tell me that as well. Thanks in advance!
