Latest Mars Reconnaissance Orbiter Stories
What advantages does the Thermal and Evolved Gas Analyzer (TEGA) have over the Viking mission's Gas Chromatograph in detecting organics?
ESAâ€™s Mars Express radar sounder, MARSIS, has looked beneath the Martian surface and opened up the third dimension for planetary exploration. The techniqueâ€™s success is prompting scientists to think of all the other places in the Solar System where they would like to use radar sounders.
NASA engineers have adjusted the flight path of the Phoenix Mars Lander, setting the spacecraft on course for its May 25 landing on the Red Planet.
A new stereo view of Phobos, the larger and inner of Mars' two tiny moons, has been captured by a NASA spacecraft orbiting Mars. Phobos, only about 22 kilometers (13.5 miles) in diameter, has less than one-thousandth the gravity of Earth.
NASA's Mars Odyssey orbiter has found evidence of salt deposits. These deposits point to places where water once was abundant and where evidence might exist of possible Martian life from the Red Planet's past.
Scientists studying images from The University of Arizona-led High Resolution Imaging Experiment camera on NASA's Mars Reconnaissance Orbiter have discovered never-before-seen impact "megabreccia" and a possibly once-habitable ancient lake on Mars at a place called Holden crater.
A NASA spacecraft in orbit around Mars has taken the first ever image of active avalanches near the Red Planet's north pole. The image shows tan clouds billowing away from the foot of a towering slope, where ice and dust have just cascaded down.
Liquid water has not been found on the Martian surface within the last decade after all, according to new research.
Three Mars spacecraft are adjusting their orbits to be over the right place at the right time to listen to NASA's Phoenix Mars Lander as it enters the Martian atmosphere on May 25. The lander will use a robotic arm to put samples of soil and ice into laboratory instruments.
Mars has an ethereal, tenuous atmosphere at less than 1 percent the surface pressure of Earth, so scientists working on HiRISE, are challenged to explain the complex, wind-sculpted landforms they're now seeing in unprecedented detail.
