On the night of Curiosity’s planned landing in the Red Planet, Mars is low in the southwest along with Saturn as shown in this 20-second exposure made at 9:15 p.m. CDT from the Chicago area.
Saturn appears above Spica, the brightest star in Virgo.
In about a week, Mars passes between Saturn and Spica.
