Professor Mark Sims on the discovery that Beagle 2 made it to the surface

Stratigraphy in Gale Crater on Mars indicates the effects of megafloods in the distant past, most likely caused by the heat released in a major impact.

NASA’s Curiosity Mars rover has started a summer road trip, skirting dangerous sand as it heads for its next target.

A European spacecraft cruising toward Mars fired its main engine, tweaking its trajectory and helping set up for carefully-choreographed simultaneous maneuvers to place part of the tandem mission into orbit around the red planet and deposit a stationary battery-powered lander on the Martian surface.
