					Team STELLAR Potential Landing Sites

Criteria
• Safe Landing Site
– Relatively flat surface – Few rocks and craters

• Previously Explored Area
– Photos of spacecraft for extra money

• Drivable Terrain
– At least 500m of terrain safe to drive over

• Near Side of the Moon
– Necessary for radio communications

Prior Landings
• 62 Potential Manmade Targets
– 4 Farside landings – Unsuitable – 15 Unknown sites – Coordinates not established

• 43 Known landing sites
– 28 Unmanned Probes – USA, USSR, Japanese probes – 6 Manned Landings – Apollo 11-17, excepting 13 – 9 Debris Sites – Apollo Ascent crashes, 3rd stage crashes

• 6 Apollo Landing Sites
– Best chance to observe manmade material

Apollo 11 Sea of Tranquility
Pros • Historical Significance • Originally chosen as a safe target Cons • Small size of explored area
– Could be difficult to find landing zone

• Reports of extensive craters and boulders in surrounding areas

Apollo 11 Sea of Tranquility

Apollo 12 Ocean of Storms
• • •
• Pros Site of first pinpoint landing Site of Surveyor III probe Large tracts of open, flat terrain Gentle slopes on local craters Cons Snowman crater formation Crescent sisters craters to the north

• •

Apollo 12 Ocean of Storms

Apollo 12 Ocean of Storms

Apollo 14 Fra Mauro Highlands
•
• Pros Many different objects on the surface to find and photograph First use of cart would have tracks to follow Cons High elevations Many craters in surrounding areas Large boulders around landing site

• •
•

Apollo 14 Fra Mauro Highlands

Apollo 15, 16, 17
• •
• Pros Lunar rovers present at sites Large area explored = Easier to find Interesting geology for science applications Cons High elevations Mountainous terrain Large boulders and rocks Steep inclines

• • • •

Apollo 15 Hadley Rille

Apollo 16 Sea of Descartes Plains

Apollo 17 Valley of Taurus Littrow

Apollo Landings

Recommendation: Ocean of Storms
Due to its multiple targets, (Apollo 12 descent stage, Surveyor II) and open areas of flat terrain the Ocean of Storms would seem to be the best landing site.
If possible, photographs should be taken of the target destination from lunar orbit before attempting a landing, so that any unknown hazards can be evaluated.

For scientific mission objectives as well as for trajectory analysis, it will be necessary to obtain more expert opinions.
