08/22/2013 – Ephemeris – A new mission to the moon starts next month
Thursday, August 22nd. The sun rises at 6:53. It’ll be up for 13 hours and 42 minutes, setting at 8:36. The moon, 2 days past full, will rise at 9:11 this evening.
Though we all know that the moon is airless, surrounded by a better vacuum that we can pump down on the earth. Nonetheless the moon has a tenuous atmosphere of gas and dust. Next month NASA has scheduled the launch of another unmanned spacecraft to the moon. This one is LADEE, an acronym for Lunar Atmosphere and Dust Environment Explorer. It will take 30 days to reach the moon and will measure the dust and tenuous atmosphere of the moon. It will looking for the high altitude glows seen by the Apollo astronauts above the moon. There is also a demonstration laser communication system, at least six times faster than current radio technology.
Times are for the Traverse City/Interlochen area of Michigan. They may be different for your location.
