Actually, I was thinking about making special Space Center for survival update. But im not sure what features exept cargo delivering would be usefull at all. You can't see anything from space so it wont be useful for scouting, you can't call in backup from orbit unless you use wireless glitch or mods. Maybe sending stages that transform into outpost or a small shelter just like second stage 5L. Well, we will see how survival works and what we can do with it :)

And answer related to another completely unrelated question :D
Yes it is possible, but not with current SSTO. There should be way to activate it from the pod when it(pod) is inside. Slight modifications for the SSTO are needed for that. I'll maybe even build completely new SCS for SSTO's only as I have other ideas for the different payloads (maybe even space station parts)

P.S. Oh well... "im planning..." "im thinking..." when will i start building new stuff already? :D

Batska! I just thought of something! Do you think that you might try to make some sort of a cargo/supply shuttle when survival/inventory/cargo gets added? I think it'd be awesome to launch some supplies in either the SSTO or a 2-stager. Perhaps the final pod of the multi stage rockets could be sent off to the side after decoupling, much like your SSTO when combined with the rover.

Another completely unrelated question: do you think it'd be possible to make a passenger module for the SSTO? An idea is sort of forming in my mind, but I'd need to have someone else either in the rocket or launching it, and I don't have friends... XD

Anyway, I love the new first/second stages! Keep up the good work!
