🚀 Welcome to Apoapsis

Build a rocket, fly it to orbit, and chase the contracts. Real orbital mechanics, real Tsiolkovsky physics, two moons to visit.

Builder

Click parts on the left to stack them. S0/S1/... buttons assign stages. Stage with the highest number fires first. Use the MunShip preset if you want a ready-to-fly design.

Flight — the 10 keys you need

W/S throttle   A/D pitch   Q/E yaw   Space stage

0-9 SAS modes (prograde, retrograde, target, etc.)

L autopilot (ascent on Earth — moon landing once in Mun/Minmus SOI)

M map view   N maneuver node   ,/. time warp

G deploy chute   Shift+WASDQE = RCS translate (precision docking)

First mission

Load MunShip, press LAUNCH, then hit L to let the autopilot put you in orbit. On the maneuver panel click → Mun, warp (.) until the burn window, hit 8 for SAS MANEUVER, then W to throttle up.
