^^ what that says. Height is easy but you’ll only stay as high as the atmosphere limits by use of a balloon until the balloon bursts, then just plummet straight back down again. Orbit requires a lot more velocity.
Think of orbit as going as fast as possible forwards so that you miss the ground 😀
I.e. you’re being pull towards the ground by gravity but by moving forwards fast enough and given the curvature of the planet, you stay an equal distance from the ground. You’re still falling though (hence the feeling of weightlessness).
The other option is the tether out to a geostationary distance (much much much higher than the ISS orbits). The rotation of the tether due to earth’s rotation by the time you get to the geostationary point will be the speed required for orbit. Could then cut the tether loose. Though have to get the thing out there in the first place though.
Virgin Galactic “space” flights are basically just a straight up and down again. They will not be orbital flights as that’s immensely more difficult, dangerous and expensive. They’ll go out to the edge of the atmosphere and a parabola flight so you get weightless feel also. It’s not a cheap way to get people into space though.
Other thing is once in orbit, because you are travelling so fast it then becomes very dangerous to get back because the only generally viable way of slowing down is to use the resistance of the atmosphere.
