New studies of ripples and dunes shaped by the winds on Mars testify to variability on that planet, identifying at least one place where ripples are actively migrating and another where the ripples have been stationary for 100,000 years or more. Patterns of dunes and the smaller ripples present some of the more visually striking landforms photographed by cameras orbiting Mars.  Investigations of whether they are moving go back more than a decade. Two reports presented at the 41st Lunar...

NASA's newest Mars orbiter, completing its fourth year at the Red Planet next week, has just passed a data-volume milestone unimaginable a generation ago and still difficult to fathom: 100 terabits. That 100 trillion bits of information is more data than in 35 hours of uncompressed high-definition video. It's also more than three times the amount of data from all other deep-space missions combined -- not just the ones to Mars, but every mission that has flown past the orbit of Earth's moon....

Extensive radar mapping of the middle-latitude region of northern Mars shows that thick masses of buried ice are quite common beneath protective coverings of rubble. The ability of NASA's Mars Reconnaissance Orbiter to continue charting the locations of these hidden glaciers and ice-filled valleys -- first confirmed by radar two years ago -- adds clues about how these deposits may have been left as remnants when regional ice sheets retreated. The subsurface ice deposits extend for hundreds of...

Near the center of a Martian crater about the size of Connecticut, hundreds of exposed rock layers form a mound as tall as the Rockies and reveal a record of major environmental changes on Mars billions of years ago. The history told by this tall parfait of layers inside Gale Crater matches what has been proposed in recent years as the dominant planet-wide pattern for early Mars, according to a new report by geologists using instruments on NASA's Mars Reconnaissance Orbiter. "Looking at the...

Scientists Taking Suggestions on Where to Image the Red Planet Using NASA Satellite The most powerful camera aboard a NASA spacecraft orbiting Mars will soon be taking photo suggestions from the public. Since arriving at Mars in 2006, the High Resolution Imaging Science Experiment, or HiRISE, camera on NASA's Mars Reconnaissance Orbiter has recorded nearly 13,000 observations of the Red Planet's terrain. Each image covers dozens of square miles and reveal details as small as a desk. Now,...

The team operating NASA's Mars Reconnaissance Orbiter plans to uplink protective files to the spacecraft next week as one step toward resuming the orbiter's research and relay activities. Since the orbiter spontaneously rebooted its computer on Aug. 26, flight team engineers have been examining possible root causes and repercussions of that incident and three similar events this year on Feb. 23, June 3 and Aug. 6. Meanwhile, the team has kept the spacecraft in a precautionary, minimally...

Because the first extrication drive for Spirit, on Sol 2088 (Nov. 17), stopped as soon as it began due to an exceeded tilt limit, the plan for an extrication drive on Sol 2090 (Nov. 19) will essentially be a repeat of the first drive plan, but with improved rover attitude knowledge. The updated attitude knowledge comes from the rover's measurement of its tilt on Sol 2088. In the Sol 2090 plan, the rover will be instructed to drive straight ahead in two steps. Each step will be a commanded...

Winter images of NASA's Phoenix Lander showing the lander shrouded in dry-ice frost on Mars have been captured with the High Resolution Imaging Science Experiment, or HiRISE camera, aboard NASA's Mars Reconnaissance Orbiter. The HiRISE camera team at the University of Arizona, Tucson, captured one image of the Phoenix lander on July 30, 2009, and the other on Aug. 22, 2009. That's when the sun began peeking over the horizon of the northern polar plains during winter, the imaging team said....

An armada of robots may one day fly above the mountain tops of Saturn's moon Titan, cross its vast dunes and sail in its liquid lakes. Wolfgang Fink, visiting associate in physics at the California Institute of Technology in Pasadena says we are on the brink of a great paradigm shift in planetary exploration, and the next round of robotic explorers will be nothing like what we see today. "The way we explore tomorrow will be unlike any cup of tea we've ever tasted," said Fink, who was recently...


Word of the Day
cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
