KerbSat 2, an additional communications satellite, is launched.  It is identical to KerbSat 1, except for a longer range communications dish similar to the one on Explorer 1.  KSEA engineers realized only too late that by the time Explorer 1 reached Eve, the antenna on board the probe would reach Kerbin, but the relay satellite wouldn’t be able to transmit back!  The launch goes well, and the satellite is put into a high polar orbit over Kerbin.

Additionally initial construction work begins on a Aurora 4 – the first test of the full Mun-mission Sarnus V rocket stack.  The current thought is to launch, test the docking and transposition maneuver, then re-enter to test the Aurora Spacecraft.  If all goes well Aurora 5 should be set to go to Mun!
