E’ molto probabile che il design finale del LSAM sarà molto differente rispetto ai primi disegni.Ad esempio ora si pensa ad un airlock fissato al modulo di discesa,e destinato a rimanere sulla luna dopo la partenza della cabina con l’equipaggio.Pare che la NASA sia orientata ad abbandonare sulla superficie anche le tute EVA,lasciandole all’interno dell’airlock.Se la decisione venisse confermata sarebbe chiaro che le tute degli astronauti del CEV non sarebbero IEVA come quelle dell’Apollo,ma vi sarebbero combinazioni lancio/rientro (probabilmente derivate dalle attuali ACES) e scafandri per attività extraveicolare.Da http: //www.usspacenews.com/

Great (and early) ideas are coming forth about the LM for CEV. The development of the CEV
LM would start about 2009-2010. One concept (that will be published next year) is for a LCCL
(Lunar Crew/Cargo Lander). The LCCL is about 2.5 times the length of an Apollo LM and ruffly
the same hight. It has an external airlock/crewlock not part of but soft mounted to the aft of the
Assent stage. Access to the Lunar surface is via the crewlock at the aft end of the Assent
stage. The crewlock will stay on the surface fixed to the decent stage when the crew departs.
Along with crew equipment, surface operations support hardware, Lunar EVA spacesuits and
other high value items could be left behind in the crewlock for reuse or to serve as a source of
spares parts for future expeditions (several US spacesuits on ISS failed when a build of
biomass clogged fans and pumps).
The cargo version would have a crew habitat in place of the assent stage and the same
crewlock. Tanks for holding fuel what instead hold water. Solar power and battery systems
would initially provide power to the LCCL habitat. Future power could be provided by a Lunar
Surface Reactor (based on research done at MSFC). The cargo variant could have 6 legs.
The lander has a 3 engines with a single engine out capability. Heavy cargo would be flown in
place of the habitat. Cargo variants LCCL would not need a CEV for leaving Earth orbit or
landing on the moon. The real thing may never look like this, but it’s fun read about new
