09.20.07 - NASA's Mars Reconnaissance Orbiter is examining several features on Mars that address the role of water at different times in Martian history.
09.19.07 - Think you have to be a scientist to contribute to cutting-edge Mars research? Think again!
08.24.07 - Diagnostic tests and months of stable, successful operation have resolved concerns raised early this year about long-term prospects for the powerful telescopic camera on NASA's Mars Reconnaissance Orbiter.
03.22.07 - NASA's Mars Reconnaissance Orbiter put itself into safe mode -- a precautionary status with minimized activities -- on March 14. It remained healthy and in communication with Earth, but with no science observations, while the flight team examined engineering data. On March 20, the team brought the spacecraft back out of safe mode.
02.15.07 - Liquid or gas flowed through cracks penetrating underground rock on ancient Mars, according to a report based on some of the first observations by NASA's Mars Reconnaissance Orbiter.
02.07.07 - NASA's Mars Reconnaissance Orbiter spacecraft this month is set to surpass the record for the most science data returned by any Mars spacecraft. While the mission continues to produce data at record levels, engineers are examining why two instruments are intermittently not performing entirely as planned.
01.11.07 - NASA's Mars Reconnaissance Orbiter has a new project manager.
12.22.06 - NASA's Mars Reconnaissance Orbiter has a new project manager.
12.13.06 - Layers on Mars are yielding history lessons revealed by instruments flying overhead and rolling across the surface.
12.04.06 - New images from NASA's Mars Reconnaissance Orbiter show three additional NASA spacecraft that have landed on Mars: the Spirit rover active on the surface since January 2004 and the two Viking landers that successfully reached the surface in 1976.
10.16.06 - During its first week of observations from low orbit, NASA's newest Mars spacecraft is already revealing new clues about both recent and ancient environments on the red planet.
09.29.06 - Mars is ready for its close-up. The highest-resolution camera ever to orbit Mars is returning low-altitude images to Earth from NASA's Mars Reconnaissance Orbiter.
09.19.06 - NASA's Mars Reconnaissance Orbiter has extended the long-armed antenna of its radar, preparing the instrument to begin probing for underground layers of Mars.
09.12.06 - NASA's newest spacecraft at Mars has completed the challenging half-year task of shaping its orbit to the nearly circular, low-altitude pattern from which it will scrutinize the planet.
06.19.06 - NASA's newest spacecraft at Mars has already cut the size and duration of each orbit by more than half, just 11 weeks into a 23-week process of shrinking its orbit.
04.13.06 - Researchers today released the first Mars images from two of the three science cameras on NASA's Mars Reconnaissance Orbiter. Images taken by the orbiter's Context Camera and Mars Color Imager during the first tests of those instruments at Mars confirm the performance capability of the cameras.
03.31.06 - NASA's Mars Reconnaissance Orbiter yesterday began a crucial six-month campaign to gradually shrink its orbit into the best geometry for the mission's science work.
03.24.06 - The first test images of Mars from NASA's newest spacecraft provide a tantalizing preview of what the orbiter will reveal when its main science mission begins next fall.
03.10.06 - With a crucially timed firing of its main engines today, NASA's new mission to Mars successfully put itself into orbit around the red planet.
03.08.06 - NASA's Mars Reconnaissance Orbiter has begun its final approach to the red planet after activating a sequence of commands designed to get the spacecraft successfully into orbit.
