This challenge is now closed I've stopped reviewing new entries a few weeks ago. Since then, volunteers have taken over. While this worked good enough to get a last batch of entires reviewed (really, praise the volunteers), I don't think this state of affairs should continue forever. Furthermore, the great Aerodynamics Overhaul of KSP 1.0 has changed the nature of the challenge dramatically. Eve still has the highest gravity and the densest atmosphere, but it's a different challenge now. Landin
