Through the Looking Glass
• Return humankind to the moon
• Establish semi-permanent structures
• Give back to the scientific community
– Observatories
– Traverse with multiple stops for geological studies
– Each phase studies additional areas
• Invaluable experience for future Mars projects

Lunar Geology
• Discover location of
resources for ISRU
• Lunar formation
• Earth and other
planetary meteorite
remains
– Origin of life/Astrobiology
– History of planetary
formation
• Samples for lunar
machinery development

South Pole-Aitken Basin
• Largest impact basin in the solar system
• Different element concentration from the rest of the Lunar
surface
• Thinner crust
• Mantle may be present
– Compositionally different from crust

Why Manned Exploration?
• Humans versus robots debate
• Humans have greater versatility than robots
– Flexibility of tasks that can be accomplished
– Maneuverability/Range of motion
– On site decision-making
– Ability to reason to solve unexpected problems
• No time delay from telerobotics
• Engages public interest

Traverse Phase I
• Start: Landing Zone
at Mons Malapert
– Prepare Rovers
– Begin star-tracking
• First Stop:
De Gerlache Crater
• Second Stop:

Support
• Twin rovers in case of a malfunction or
accident
• Main Rover
– Basic tools and drill for geological sampling
– Storage for Earthbound samples
– Small quarters for multi-day traverses or site
studies
– Pressurized Lab for preliminary on-site testing
• CEV passes overhead approximately
every 90 minutes

Future Studies:
• Ideally the entirety of the Lunar surface will
be traversed and compositionally mapped
• Heavy duty drilling operations to study
deeper layers of the lower crust and mantle
• Very long traverses
• Completely equipped Mobile Lab (or
permanent base) for thorough on-site
testing
