Imagine: an earth-like, inhabited planet slowly grows uninhabitable over hundreds of thousands of years and the atmpsphere no longer supports life. Would it be possible for that change to have made it easier for stuff to enter the atmosphere? To face less (but still some) resistance? I'm not really wanting to just straight-up weaken the atmosphere, but I need a space ship to crash on this planet and not burn up all the crew on entry while also being terraform-able. Thanks so much!
