Essentially the basic Apollo LM modified for extended lunar surface stays. This was forseen to be the workhorse of both Apollo Applications Extended Lunar Surface Missions beginning in 1970 and still be used to shuttle crews to the surface to larger LESA (Lunar Exploration System for Apollo) in the mid- to late- 1970's. Changes included additional water, oxygen, LH2, and Lox tankage in the descent stage in the payload bays; fuel cells in the ascent stage; a redundance Lox tank in the ascent stage over the back of the LM; and additonal micrometeorite and radiation shielding. This would permit the LM to accomodate a crew of three for up to 14 days. The LM Taxi would land near the previously-landed LM Shelter or LESA Shelter, where the crew would spend most of its time during surface explorations lasting from 14 days to three months.
