Comet Siding Spring Animation

ESA and NASA announce new missions to study a pristine comet, the solar corona and how the solar wind interacts with Earth’s atmosphere.

An independent review board has recommended that NASA extend the Juno and InSight missions now studying Jupiter and Mars.

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.
