        Beat me to it. But once you are in orbit, the view is so worth it!

        @paulg are you on vacation in non-US TZ; or do you just stay up late (assuming PST)? How does that tally with 7yo wakeup? I love my kid time dearly but my candle gets both ends burned

        is the peak energy load at ignition & initial liftoff? would it be better to catapult the initial 20 seconds of launch to extend the onboard fuel supplies/ run the initial acceleration horizontally in a hyperloop environment then transition to vertical and atmospheric pressure.

        The most difficult part of becoming an interplanetary species is getting off the Earth and into orbit en masse, what we might call the “first mile” problem. Actually, since the most accepted demarcation of space is the Karman line, which is 100 km up from the surface.
