| Jan 9, 2022 at 14:10 | comment | added | Sascha | @toolforger: Well. I am not sure how long that development may or may not take - it could be that the boundary conditions (e.g. weight/propellant needs) required the landing vehicles to be air breathing. If you just assume that the question meant "they can call the home planet to develop something to take off, and wait until that is finished", the no planet will be safe against leaving it. | |
