December 20, 2007

This is a special day that happens only every 26 months when Earth is exactly between the Sun and Mars. Find out more about opposition and experiment with Mars and Earth in their orbits.

Conspicuous dark streaks atop icy dunes on Mars allure scientists and non-scientists, yet their origin remains a mystery. Perhaps they are small avalanches or patches of sand covered by a thin veneer of ice. Perhaps they formed when cold gas jets of evaporating ice spewed dust onto the surface.

Imagine being able to point a camera at such features from 60 million miles away! Students in Budapest, Hungary effectively did that, selecting this site for observation from orbit through a program that invites the public to help NASA select targets for imaging on Mars.

read the article 'Lava 'Leaps Out' in 3-D!'
October 18, 2007

Dazzled by the beauty of the strange features in the Athabasca Valles channel system on Mars, geologist Windy Jaeger pondered their origin. In a new paper, she concludes that lava filled the channel system to the brim and then drained away leaving a thin coating of hard lava rock to preserve the underlying landscape. Other unique features indicating that massive lava flows once filled the channels are hydrovolcanic cones that formed when water met lava and boiled explosively, leaving behind small, conical and ring-shaped features visible in and around the dune field (upper left).

CRISM View is a first-of-its-kind opportunity to watch Mars through the "eyes" of the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) - as if you were riding along with it on the Mars Reconnaissance Orbiter!

The team operating the mineral-mapping camera (CRISM) on NASA's Mars Reconnaissance Orbiter offers Web users a simulated view, in real time, of what part of Mars the instrument is seeing as it orbits the planet. The viewer is based on the application that team members use to monitor their instrument.

June 28, 2007

As engineers and scientists anticipate the Opportunity rover's long-awaited descent into "Victoria Crater," they have a bird's-eye view thanks to the HiRISE (High Resolution Imaging Science Experiment) camera aboard NASA's Mars Reconnaissance Orbiter.

Opportunity's tracks decorate the edge of Victoria Crater like a constellation in our night sky. These tracks represent nearly a year's worth of investigation to characterize the massive depression before deciding whether or not to enter.

Plans are to take a dip into the crater around the second week of July and then proceed down, if driving conditions are favorable.

May 17, 2007

Mars Reconnaissance Orbiter is an overachiever! About six months into its science-gathering phase and the orbiter has already returned 11 Terabits of data – that’s enough to fill over 2,000 CDs!

May 4, 2007

Full Image and Caption

Erosion has exposed light-toned, layered rocks on the northern rim of Hellas Basin, the largest impact crater on Mars. Details in the layering seen in this image from the High-Resolution Imaging Science Experiment reveal variations in brightness that may indicate differing mineralogies.

January 11, 2007

Using the high-resolution camera, visual clues such as peaks and craters seen in earlier images, and old-fashioned detective skills, scientists were able to identify the 1997 Pathfinder mission within a vast landscape of seemingly homogenous Martian terrain.
