Phases of the Moon

This month at the South Mountain Environmental Education Center was all about the Moon. We discussed the Apollo Program and the detail workings of the Guidance and Navigation Computer and the Alignment Optical Telescope used to determine their position that lead to the lunar landings. We also discussed the Moon's origin and features. Here we demonstrate what causes the phases of the Moon. Afterwards outside we had a video camera attached to one of our telescopes to show the crescent Moon on a TV screen so attendees could see as a group the details we discussed inside. Then they used our other telescopes to see the features up close. Another fun event! Next month on Friday, 29 September the event will be all about the Sun, our star.
