Former deputy project scientist and current science team member J. Marshall Shepherd tells us why missions like NASA's Global Precipitation Measurement (GPM) are vital to our way of life.
Check out this unusual crater on Mars. It's not a very big one, less than 500 meters in diameter, and yet it has two rings. Most craters on Mars this size are simple bowl shapes. What's going on here?
On Sunday, 19 October 2014, at around 18:30 UTC, comet C/2013 A1 – known widely as 'Siding Spring' after the Australian observatory where it was discovered in January 2013 – will make a close fly-by of Mars.

During the third lunar day of Change'3 surface operations the lander operated normally, performing ultraviolet astronomy and imaging Earth's plasmasphere. The rover's instruments were working, but the rover did not move.
