Mars’ moon Phobos is captured in a daytime image by Curiosity (NASA/JPL-Caltech/MSSS)
A raw image taken on September 21 by Curiosity’s right Mastcam shows a daytime view of the Martian sky with a crescent-lit Phobos in the frame… barely visible, yes, but most certainly there. Very cool!
The image above is a crop of the original, contrast-enhanced and sharpened to bring out as much detail as possible.
The 13-km-wide Phobos has been spotted several times before by Mars rovers, most recently during a solar transit on September 13 (sol 37) but I’m not sure if it’s ever been clearly captured on camera during the day before (i.e., not passing in front of the Sun.) If not, this will be a first!

Added 9/28: According to Universe Today publisher Fraser Cain, this is “the most dramatic space picture of the year”… whether you agree or not, hear what he had to say on this and other recent news during the September 27 episode of the Weekly Space Hangout.
