I really really wanna see us climbing back up afterwards too, actually getting to work towards an escape to the surface after obtaining the cargo would feel so good in my opinion. As for how that would go exactly, as being able to go up is not as guaranteed as being able to go down, I'm not sure, but I do have some ideas or guesses especially if this experimental technology we are trying to get is going to lead to the events of Gunsaw in some way.
