Mars TOP STORY
NASA's Curiosity Mars rover is expected to remain stationary for several days of engineering analysis following an onboard fault-protection action on Feb. 27 that halted a process of transferring sample material between devices on the rover's robotic arm.

NWA 7034, a meteorite found a few years ago in the Moroccan desert, is like no other rock ever found on Earth.
The Mars Opportunity rover has driven 25.9 miles (41.7 kilometers) since it landed in the Meridiani Planum region of Mars on Jan. 25, 2004 (Universal Time, which was Jan. 24, PST). That is farther than any other off-Earth surface vehicle has driven.
JPL engineers are working on a small helicopter that could 'scout' a trail for future Mars rovers, but getting a chopper that could fly in the Martian atmosphere is tricky.

These new images from the high-resolution stereo camera on ESA's Mars Express show Nili Fossae, one of the most enticing regions on Mars.
NASA and Microsoft have teamed up to develop software called OnSight, a new technology that will enable scientists to work virtually on Mars using wearable technology called Microsoft HoloLens.
The UK-led Beagle-2 Mars lander, which hitched a ride on ESA's Mars Express mission and was lost on Mars since 2003, has been found in images taken by a NASA orbiter at the Red Planet.
Although Mars is a very alien planet, some aspects of its geology are surprisingly familiar. This Mars Express image shows a snippet of a region of Mars filled with cliffs, trenches, faults, giant plateaus and volcanoes.
This image of an area on the surface of Mars, approximately 1.5 by 3 kilometers in size, shows frosted gullies on a south-facing slope within a crater.
NASA and an international team of planetary scientists have found evidence in meteorites on Earth that indicates Mars has a distinct and global reservoir of water or ice near its surface.
