  • Curiosity Rover Landing Parties – most of us saw them on TV and internet

Major Presentation:

“Lunar Geology – Continued,” Eric Douglass

This was a continuation of a talk from 2 months ago.  Eric began by talking about “Basins on the Moon” and spoke of many crater formations that may exist.  Of course, the craters are mostly created by collisions of objects being pulled into the moon by its gravity.  Under such large pressure, the solid moon surface behaves like sand, re-forming into circular patterns around the point of impact.  Based upon the size of the impact and the angle of the impact, the new crater can take on different physical characteristics.  Many times, the crater wall collapses to form a flat crater floor with sloping side walls.  An impact coming from an angle can form a elliptic or oblong shape to the wall structure.  The energy released by the collision can, not only form the crater wall, but create concentric rings/ridges farther out from the crater’s center.  Eric had several photographs to display this phenomenon.  Many of the photos showed ridges that were quite old and ‘weathered’ and some that were recently made (in the past few thousand years).

While comparing the formations on the Moon, Eric compared the similaririties of the volcanic fissures found in Hawaii and lava flows from different volcanoes here on Earth.
