Basically, you could Launch launchpads into space. For example, you have a base on Smars, and want to do missions there without having to launch them all the way back at Smearth. Well, you could send a Lander with a launchpad on it. Maybe it folds up to save space. You land that on your Smars base, and you now have the option to start there instead of on Smearth! If that seems to OP, then maybe you need to mine resources or it costs ingame money to do it. Another example: You have a space station around, Smaturn, for example, and you want to add modules to it, but Smaturn is far away from Smearth and it is not easy to get a space station module from Smearth to Smaturn, especially if it the module is big! What you could do instead is dock an assembly port to the station, which would work the same as the portable launchpad in the last example. You get the option to start at the space station instead of Smearth! You then can assemble your new station module AT the station instead of all the way back at Smearth! Extraplanetary launchpads would be an awesome addition to Simplerockets 2 because it would be efficient, and fun! (It might work similarly to the Extraplanetary Launchpads mod for Kerbal Space Program!)
