Algodoo

A Shenzhou spacecraft landed on the surface of an airless planet,
with the Tiangong-3 space station orbiting overhead. Test your
orbital rendezvous skills with these two spacecraft!

CONTROLS:
W/A/S/D: directional control thrusters
Q/E: rotational control thrusters
T: Shenzhou main engines
J/K: open/close Tiangong's dock
X: decouple Shenzhou

EDITOR'S NOTE: The docking system is yet imperfect. Be extremely
careful not to clamp the dock too hard, or it will eject the Shenzhou,
and possibly de-orbit the station.
