03.09.09 - New images from two observations of the Martian moon Deimos and more than 600 observations of Mars, acquired by the high-resolution camera (HiRISE) on NASA's Mars Reconnaissance Orbiter, became available for viewing Monday.
02.25.09 - Images from NASA's Mars Reconnaissance Orbiter show a type of rock fracturing that here on Earth is caused by rapid cooling of lava.
12.08.08 - The team operating the highest-resolution camera orbiting Mars has posted 362 stereo images, providing three-dimensional views of mounds, canyons, gullies and other features.
10.15.08 - In a newly released image from NASA's Mars Reconnaissance Orbiter, an unusual mound punctuates dramatic stripes of Martian polar terrain where icy layers are eroding.
09.19.08 - More than 1,500 newly released images from a spectrometer instrument on NASA's Mars Reconnaissance Orbiter will boost understanding of what minerals exist where on the Martian surface.
09.18.08 - Newly posted images from more than 1,000 observations by the high resolution camera on NASA's Mars Reconnaissance Orbiter reveal details as small as a desk.
09.18.08 - Water may have played a role in shaping parts of the Martian landscape a billion years longer than previously indicated, according to interpretation of images from NASA's Mars Reconnaissance Orbiter.
› Planetary Science Institute site →08.07.08 - Layers of clay-rich rock at a potential landing site for future Mars rovers suggest a long-term history of liquid water activity, possibly including hot water, at the now-dry site.
05.06.08 - A new online map lets visitors explore Mars' past through a collection of high-resolution observations from one of the most powerful spectrometers ever sent to the Red Planet.
05.06.08 - NASA's Mars Reconnaissance Orbiter has captured an image of dust devils -- swirling dust storms -- near the landing site for the Mars Phoenix lander on the northern Martian plains.
03.31.07 - High school students in three states are working with Mars researchers on observations for an instrument on NASA's Mars Reconnaissance Orbiter.
11.27.07 - The two moons of Mars, Phobos and Deimos have been the focus on recent observations by the Compact Reconnaissance Imaging Spectrometer of Mars, an instrument on NASA's Mars Reconnaissance Orbiter.
09.24.07 - A spectrometer instrument on NASA's Mars Reconnaissance Orbiter checked to see whether a fresh deposit of bright material in a gully on Mars contained mineral evidence of liquid water carrying the material. The examination found no sign that liquid water played a role.
08.29.07 - The High Resolution Imaging Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter has confirmed that a dark pit seen on Mars in an earlier HiRISE image really is a vertical shaft that cuts through lava flow on the flank of the Arsia Mons volcano.
07.25.07 - NASA's Mars Reconnaissance Orbiter resumed normal operations on July 24, with all instruments operating and gathering data.
07.20.07 - Engineers are gathering and analyzing engineering data to understand the cause of a software error between NASA's Mars Reconnaissance Orbiter and one of its instruments.
06.04.07 - Explore hundreds of sweeping images from NASA's Mars Reconnaissance Orbiter with new user-friendly features at the Web site of the mission's high-resolution camera.
11.17.06 - An orbiting NASA spacecraft just starting to study Mars with six science instruments has successfully tested another key part of its payload, a versatile radio for relaying communications with robots on the surface of Mars.
11.08.06 - Navigators on the Mars Reconnaissance Orbiter mission don't have much free time. For weeks, they have been too frantic to chronicle their experiences during the critical aerobraking and orbit adjustment periods.
09.27.06 - The mineral-mapping instrument on NASA's Mars Reconnaissance Orbiter has successfully removed its lens cover and is ready to start observing the planet. The cover protected the lens of the Compact Reconnaissance Imaging Spectrometer for Mars while the spacecraft was shrinking its orbit by repeatedly dipping into Mars' atmosphere.
