I was surprised to see the quote 'slip the bonds of earth' on a circular orbit. This seems pretty bound to earth. Wouldn't it have made more sense to include a parabolic escape trajectory? --[[User:Quantum7|Quantum7]] ([[User talk:Quantum7|talk]]) 10:01, 25 June 2018 (UTC) | I was surprised to see the quote 'slip the bonds of earth' on a circular orbit.

:Maybe because the hard part is attaining a stable orbit. Once you do that, it's relatively trivial to escape it. Indeed even the orbit itself, while being determined by Earth, can be considered an escape since you will never again come back to Earth as long as that orbit is maintained. So Randall may have considered that close enough to talk about escaping the bonds of earth (which the stable orbit accomplished) and traveling to the stars (which is the logical next step; or at least to moons and planets so far in our case).

− | When Jane's | + | When Jane's Defense discusses strategic (read: nuclear) weapons systems, they do not distinguish between satellite delivery vehicles and ICBM launch vehicles. The only differences are the trajectory and the payload. This comic is definitely about satellites and ICBMs. I'm new here, sorry if I'm not signing this properly --OtherBarry-- |
