The core of the Harmony Space Station launches on top of a Sarnus V Heavy Launcher early in the morning of Day 148!  As soon as the launch is complted, work starts refurbishing the launchpad for Resolute’s launch!

Automated guidance systems carry the station up to a 100k orbit… Much as simulations predicted, the station sits in orbit, with plenty of fuel to carry it (and its future modules) to Minmus!
