Went to Bop to rescue a Kerbal for a contract, but obviously over-engineered it and put like 2k extra delta-v on it. Decided I could try to land on it... On my nuke engine. Luckily I had a probe core installed so it could hold the ship upright while my Kerbal went EVA and did some sciencing. Was one of the more stressful landings because I had to pretty much land at ~2 m/s... No strong landing legs to break my descent.
