Siding Spring (02)

Today's Astronomy Picture of the Day is a nice image (courtesy of the ever amazing Damian Peach) of Comet C/2013 A1, Siding Spring, as it approached Mars. This presented us with a nice chance to study the comet as Mars happens to be orbited by five active spacecraft (and has two active rovers on its surface). I can't wait to see what the orbiters and the rovers saw!
