The Need

The Requirements

The Solution 1) Attached to the attitude control system, Cyclops starts descent 2) Penetrators are dispersed into Shackleton Crater 3-4) Cyclops continues descent 5) Cyclops lands outside Shackleton Crater 6) Attitude control system detaches from Cyclops 7) Cyclops drops off single site box, receives data from the penetrators, then begins to rove
