Kerbal Space Program

Hello,

At present engineers can fix wheels and landing gear and, well I think that's it.

So how about giving them the ability to add parts to an existing craft. Only small parts mind, small science experiments, maybe the smallest solar panel or radially mounted parachute.

Imagine a satellite in orbit, it only has a thermometer on it as that's all the player had at launch. They now have a seismograph and gravitron available. So they launch a service mission with an engineer equipped and skilled enough to add these new parts.

Perhaps they could also replace small broken parts, here I’m mainly thinking of those fragile solar panels but maybe there are others?

It would need some form of simple editing interface for launched craft but add a great deal to the usefulness of engineers.
