Again, this is all speculation so these theories are just as viable as the one I am presenting. I just don't think that he could survive falling to earth from orbit with no armour or helmet (and thus minimal, if any, kinetic barriers). I think he would just burn up in the atmosphere like so many asteroids do IRL. And do correct me if i'm wrong, but I don't believe he fell through the atmosphere in ME2. I though that Cerberus found him in orbit, which is why his body had not decayed as rapidly as it would have within an atmosphere (preservation in a vaccum i suppose?). I think he would have burned to ash otherwise...
