Have diffrent equipable jetpacks.
One with ion thrusters (respawning with these would be good) wich work only in space and on the moon runs on energy
one with atmo thrusters (buildable on planets with a couple of ores you find on planets) runs on energy
one with hydro wich works like we know today (needs lots or diffrent resources)
upgraded jetpack wich gives you a big bonus on your health and/or your inventory size and personal antenna range and needs even more resources.
Disabling the jetpack completly is impossible to combine with space.
Enambling it from the beginning makes survival on earth less immersive.
