1. Earth’s Moon - Luna

3. Lunar surface features There are 5 basic surface features

4. CRATERCRATER Named after famous scientists. Copernicus Tycho All lunar surface features are formed through impacts

5. The lunar surface gets impacted a lot! In fact, the frequency of impacts is what scares NASA the most about the dangers of a permanent moon base. A lack of atmosphere leaves the surface unprotected against the smallest and largest of meteors.

6. Lunar regolith The lunar surface is heavily bombarded by meteorites. Each impact pulverizes the lunar rock and crushing it into finer and finer dust. As a result, the finest particles of regolith are very clingy. Astronaut have had trouble dealing with this property. New Scientist article

7. Copernicus and Tycho crater 2. Ray - rocky ejecta Impact did not pierce the lunar crust

8. 3. Highlands Mtn. ranges and the edges of craters Formed due to impact stresses on the crust “rebound” Crust rebounds and forms a highland after some impacts

10. Maria Formed when lava spewed to the surface through fractures made by early, giant impacts

12. As the crust Of the moon Cooled, large Objects Impacted the Surface and Pierced through The crust. Lava then Filled the Crater and Solidified, Creating “oceans” of Basaltic rock.

15. Rille Surface feature where hot lava has drained along the lunar surface following an impact

17. Crater w/ rays maria highlands All result from impacts!

21. Could Earth’s Moon have water locked up inside its rocks? Samples brought back from the Apollo Moon mission may indicate that the answer is yes. Water may be locked up in volcanic glass beads within the rocks.
