The Lander is at a 25 km Lunar altitude and an orbital period of approximately 110 minutes.

After separation occurs the Lander is completely self sufficient. This includes Attitude Control and Detection, Power, Communication, and Thermal Control.

The dry mass of the Lunar Lander is 79 kg and it uses 78 kg of propellant to land on the lunar surface

Sol, Josh and I think we need a slide like this that touches on how we survive the night since it was such a design driver
