Astronomy Cast 577: Mars in Opposition

by Fraser Cain & Dr. Pamela Gay

Every 2 years or so Mars lines up nicely with the Earth. It takes only 2 minutes to communicate with the rovers. You can see the polar ice caps in a small telescope. And it's the best time to send your spacecraft to the Red Planet. 

Oct 3rd: Moon & Mars conjunction, 1.1° separation.

Oct 6th: Mars opposition.

Dec 21st: Jupiter/Saturn conjunction, 0.1° separation!

Feb 18th "Percy" lands on Mars' Jezero crater.
