Couple of ideas for new achievements: Around the world: complete a round trip around Kerbin, using a jet powered aircraft. Same stuff, but for Laythe. Pole dancer: Land on both poles of Kerbin, using jet powered aircraft. UKSS - Build a space station in LKO, using more then 5/10/20/50/100 docked modules. Master of aerobreaking - Aerobreak into orbit from velocities higher then 5km/s, 8km/s, 10km/s. Ramming speed! - Collide 2 ships in space, destroying both and killing all the crew in process. Mun walk - land on both Mun and Minmus in one launch. Rock collection - Obtain surface samples from all planets and bring them back to Kerbin (transmitting science doesn't count). 'Eavy Metal - Launch a ship that weights more then 5/10/25/50 ton.
