Comet Siding Spring Animation

ESA’s Mars Express satellite, using ground-penetrating radar, has detected what appears to be a pool of liquid water below the red planet’s south polar region, a potentially habitable environment.

An animation of comet C/2013 A1 Siding Spring captured by NASA’s Curiosity Mars rover as the comet passed near the red planet.

NASA’s Ingenuity Mars helicopter completes a successful test flight, becoming the first aircraft to fly in the atmosphere of another world. Four more flights are planned.
