Working on the Moon (WOTM) is derived largely from the Apollo Lunar
Surface Journal and, like its parent, is a work in progress,
a "living" document. During the six successful landing
missions, a great deal was learned about living and working in the
lunar environment but, for those who have not studied the missions
and/or the ALSJ in detail, it can be difficult to find material
relevant to a particular topic of interest, say, astronaut
mobility or real-time interactions between the crews and ground
support staff. To help make lessons learned during Apollo
lunar surface operations more accessible, WOTM is organized by
topic. Each topic-specific section of WOTM will include a
discussion of relevant lessons learned across the six missions, a
set of links to pertinent locations in the ALSJ, and a list of
other references.
Comments and suggestions are always appreciated. Please let us know
about errors, about the clarity and utility of the material, about
additional topics that should be addressed, or sources of relevant
information. Feedback should be sent to the following address:
