Where is the line between “on Earth” and not? If you’re orbiting the planet does that still count? Do you have to be below a certain altitude? Certainly flying in an airplane isn’t enough to qualify as having left Earth. Is it leaving the earth’s atmosphere? Is that even something with a precise enough definition?

I guess what I’m saying is we should exile Elon to Mars and then start the timer.

For NASA and the U.S. military, for example, space starts at an altitude of 50 miles (around 80 kilometers), according to NOAA. However to the international community, including the Fédération Aéronautique Internationale (FAI), space starts a little higher, at 62 miles (100 km), at the Kármán line
