More Clues to Mars’ Wet Past

  On 6 June, the high-resolution stereo camera on ESA’s Mars Express revisited the Argyre basin, this time aiming at Nereidum Montes, some 380 km northeast of Hooke crater. The stunning rugged terrain of Nereidum Montes marks the far northern extent of Argyre, one of the largest impact basins on Mars. This computer-generated perspective view was [continue reading]
