I really like the idea. Sending a BOSS to the EDGE of space is a brilliant way to use the theme, and I have fond memories of Kerbal Space Program. (Plus, who doesn't want to send Jeff Bezos to space with no way home?)
But KSP gave much clearer feedback about what was going on—and hence, things like how close I was to orbit and what just killed my crew. I don't expect something as lavish as KSP, of course, but the only indication of how high I was going and how close I was to death was a few numbers in the corner of the screen...and aside from altitude (100k is the traditional line between atmosphere and space), I didn't know how big the numbers would have to get before they were good enough/too bad.
