The challenge is simple, who can get the most height using stock parts and using only sepratrons as an engine. You can build any size, any number of stages, any number of parts, or even have a kerbal sitting in an External Command Seat. The goal is to get a Kerbal as high as you can. If you bring your kerbal back safely and had the same height as someone else who didnt, you beat them. I look forward to seeing what you guys can come up with.
