Hi SRV Ron, Thanks for your reply. I think the training module is messed up - there wasn't any fuel, however I could orient the spacecraft (I guess that uses monopropellant?), and no I wasn't in time acceleration while attempting to thrust. I decided to go to the next tutorial ("Going to the Mun, Part 1"), where I could control the spacecraft and change my orbit, however the camera started freaking out and I couldn't establish an orbit around the Mun (I suppose that's an issue with outdated tutorials, then). Anyway I'm trying to build my first spacecraft and launching that into space. Thanks for your help!
