09/23/2014 – Ephemeris – NASA’s MAVEN satellite is in orbit of Mars

September 23, 2014

Ephemeris for Tuesday, September 23rd.  The sun will rise at 7:30.  It’ll be up for 12 hours and 7 minutes, setting at 7:37.   The moon, 1 day before new, will rise at 7:53 tomorrow morning.

Last Sunday evening the MAVEN spacecraft fired its six main engines in alternating pairs for 33 minutes and was captured by Mars, entering orbit around the Red Planet.  MAVEN is one of those NASA acronyms, it stands for Mars Atmospheric and Volatile EvolutioN   Once in a capture orbit, the orbit will be changed from a 33 hour orbit to a 4 ½  hour a science orbit.  It will investigate how Mars lost its original atmosphere which was dense enough to support liquid water to the thin carbon dioxide atmosphere it has today.  It has several duties October 19th when Comet Siding Spring passes Mars to detect the interaction of the comet’s atmosphere with that of Mars.  There are no cameras* on Maven, just hard data will be returned.

Times are for the Traverse City/Interlochen area of Michigan.  They may be different for your location.


* Actually I was mistaken.  There is an Imaging Ultraviolet Spectrograph aboard which will take images in the ultraviolet of Mars upper atmosphere.
