So basically, the Karman line is the theoretical highest point that an airplane can fly, or at least it was when it was calculated. If it were recalculated today it would be higher because of technological advancement. The definition used by the agencies that define it as the edge of space set an altitude near the originally calculated line. The functional difference between being above the line and below the line is that the keplar force will keep an object above the line from falling to Earth within 24 hours while drag will slow the object below the line enough for it to fall back to Earth within 24 hours. It’s fine as a functional definition but I see no reason that it should be universally applied. In the scope of this discussion why should we consider something that will fall back to Earth in 25 hours not be on Earth but something that will fall back to Earth in 23 hours to be on Earth?

The ISS was launched from Earth, in pieces but still it’s of Earth origin, and will eventually fall back to Earth. It’s inside the Earth’s atmosphere and experiences drag. It’s orbit has to be adjusted and maintained.
I like pedantry but want to go the other way. The ISS orbits in the thermosphere, still inside Earth’s atmosphere. I say that you haven’t really left Earth until you exit the atmosphere.
2·2 months agoI guess it’s worth a shot but you’d a few hundred years after the Norse abandoned their settlements in North America and about 120 years before Columbus’s first voyage.
I’m in the US and in a place that native Americans didn’t have settlements. I’m very familiar with the area and have hunted, hiked, and camped here my entire life. With no preparation or modern equipment I give myself about a week before I get eaten by wolves or a bear, maybe gored by an elk or bitten by a venomous snake. I don’t expect that I would see another human during that week. Native hunting parties visited the area so it’s not impossible that I would see someone but it’s very unlikely.
The Federation got him out during the Dominion War and made him a captain according to the games. He’s free in canon too. His name was on a list of Starfleet officers being taken into protective custody on an episode of Lower Decks.
