So, I was aiming to go to the moon and back for the first time, I brought along 2 scientists and a pilot. When I landed Successfully, I tried to get out of the spacecraft but, stupidly, had placed an RCS that obstructed the hatch. Since there was nothing else I could do, I decided to hit the space button to launch, but forgot that it was a controlled liquid rocket, so now I have no way to get back? I would attempt to send a rescue shuttle there but even If I landed safely, I don't know how to get the Kerbals out. Any suggestions on what to do?
