After many, many launches, all the Kerb-Sat communications satellites are launched. “These communication satellites are really hogging the launchpads…” Jeb points out. The lead scientist behind Kerb-Sat, Bob, points out that “with these new satellites you and Val will be able to explore even further – trust me, it’s a good idea!”
“If you say so…” Jeb replies.
Over the course of a few days all the satellites are moved from their parking orbit of 90k to a much higher orbit of 300km, then maneuvered into positions where they provide full coverage around Kerbin! A handy side effect is that (except for the poles) Kerbin now has full radio coverage!
