The largest piece of the landing gear assembly. The landing gear assemblies of the Lunar Module extend from the front and rear of both sides of the descent stage. They consist of struts, trusses, a footpad, as well as a locking and deployment mechanism. The left, right, and aft footpads have a lunar surface sensing probe. The landing gear not only buffers the impact of the lunar landing, but also prevents the vehicle from tipping over, and supports it during lunar stay and lunar launch. The lunar surface landing probes are stowed against the primary strut until the landing gear is deployed.
