Description
Set 1: 1:engine/reverse 2:bays 3:antenna/panels 4:Omnidock
Fundamentally, an Egg 3 with a pair of Newtons built in.
Thus, it has accommodation for 4. Modest propulsion (Thuds & Twitch reversers). Some RCS capability (more effective when near empty).
Launch: SAS Hold and ignition; pitch down 5 degrees at 50 m/s and SAS Sfc Prograde; raise AP to 80km, jettisoning Boar S1 when AP reaches 50km; jettison nose cone at 50 km; set Brakes at the Karman line; circularize, jettisoning Mammoth S2 when PE reaches -300 km (NEG); finish circularization, using some Radial Out component to keep time to AP positive. Ride & recover S2. Rhino S3 may be jettisoned when desired but may be useful for interplanetary travel.
NOTE: all Egg 4 action keys are in Action Set 1!
Built in the VAB in KSP version 1.11.2.
