CHAPTER 3, Logist-Ike   Part 1 : Iking, how modularity saved the mission   Things were on the loose : after a huge retroburn around Duna with a Pe far too high, the ISRU (with Bill & Val) and Heavy Nuke Pod were left almost stranded on a very elliptic orbit. Thanks to the various reconfiguration's possibilities between ships and engines,  and Ike's ability to greatly lower the Ap into Duna's system, Valentina managed to bring the ISRU onto Ike.
