ASSUMPTIONS In general, the mission plan is based upon present Apollo capabilities and ground rules. The one exception is that the redesignation capability (presumably tested in LLM-2) is used to land within rvlOO m of a preselected spot. The use of LM fuel reserves to do this must be justified by the experience of previous missions. Stay time: . A 35 hour 1 un.ar .stay time is ass11me,d with 3' EVA's ana~·Both astr·onauts ou~t sirlltiltahe'ousT ..

Mobility: All traveling is on foot at a nominal rate of 3 km/hr. A constraint imposed by the emergency oxygen system is a 1 km radius envelope centered on the LM. This may need to be reduced slightly due to rough terrain expected at Ithe LLM-3 landing site. Payload: The d$scent paylOad will consist essentially of the ALSEP configuration "B", which includes the passive. ~ $ELLCOMM, INC. - 2' -· seism~p -~. r~at: ·~fJ:o~ ':; _qcp],Q. cg;tho~e ,~g;~uge ,- .'_;zn_? __ _c~arg~?-:;.f3a::t~sie' :> e xpe;r:-liJ1~nt~ .. _-Tne q,s qent pay load :wlll co~~:~-~~ ·~o_f ~~PJ2T_QX'~JIJ§.t ~-+~-·- 50 -:q)_~':$r::foc!y ~-iirTilfe..~-(·;r(ci:c'iud'Ing-· the~-- c<5re ~ f:r.0m · ·oner'' or _tli@~-.
