Changes In Martian Sand Dunes Monitored By Mars Orbiter
2012-05-09 15:13:05

NASA's Mars Reconnaissance Orbiter has revealed that movement in sand dune fields on the Red Planet occurs on a surprisingly large scale, about the same as in dune fields on Earth. This is unexpected because Mars has a much thinner atmosphere than Earth, is only about one percent as dense, and its high-speed winds are less frequent and weaker than Earth's. For years, researchers debated whether sand dunes observed on Mars were mostly fossil features related to past climate, rather than...

NASA To Fly Deep Space Atomic Clock To Improve Navigation Technology
2012-04-11 13:29:41

When people think of space technologies, many think of high-tech solar panels, complex and powerful propulsion systems or sophisticated, electronic guidance systems. Another critical piece of spaceflight technology, however, is an ultra stable, highly accurate device for timing - essential to NASA's success on deep-space exploration missions. NASA is preparing to fly a Deep Space Atomic Clock, or DSAC, demonstration that will revolutionize the way we conduct deep-space navigation by...

12-Mile-High Dust Devil Captured On Mars
2012-04-06 03:10:32

[ Watch the Video ] A Martian dust devil roughly 12 miles high (20 kilometers) was captured whirling its way along the Amazonis Planitia region of Northern Mars on March 14. It was imaged by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. Despite its height, the plume is little more than three-quarters of a football field wide (70 yards, or 70 meters). Dust devils occur on Earth as well as on Mars. They are spinning columns of air,...

NASA Mars Orbiter Catches Serpent Dust Devil On Mars
2012-03-07 13:22:09

An afternoon whirlwind on Mars lofts a twisting column of dust more than half a mile (800 meters) high in an image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. HiRISE captured the image on Feb. 16, 2012, while the orbiter passed over the Amazonis Planitia region of northern Mars. In the area observed, paths of many previous whirlwinds, or dust devils, are visible as streaks on the dusty surface. The active dust devil displays...

Image 1 - Mars Reconnaissance Orbiter Spots Traces Of Older Mars Landers
2012-02-08 15:21:21

NASA said on Wednesday that a camera onboard its Mars Reconnaissance Orbiter recorded the first color image of Mars Exploration Rover Spirit's landing platform. The image was taken using the High Resolution Imaging Science Experiment (HiRISE) camera on the orbiter. Spirit drove off the three-petal lander in January 2004, and spent most of its six-year life in the range of hills about two miles to the east. NASA reported on May 1, 2009 that the rover got stuck in soft soil, officially...

Mars Science Lab Trajectory Maneuver Slated For Jan. 11
2012-01-07 06:08:58

Mars Science Laboratory Mission Status Report An engine firing on Jan. 11 will be the biggest maneuver that NASA's Mars Science Laboratory spacecraft will perform on its flight between Earth and Mars. The action will use a choreographed sequence of firings of eight thruster engines during a period of about 175 minutes beginning at 3 p.m. PST (6 p.m. EST or 2300 Universal Time). It will redirect the spacecraft more precisely toward Mars to land at Gale Crater. The trajectory resulting...

Tour Detailed Images Of Mars With HiView Tool
2011-12-08 04:47:49

An improved tool debuted Wednesday for viewing channels, dunes, boulders and other features revealed in the huge image files from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.  The new tool, HiView, offers the best way to take a personal, virtual hike through any of thousands of square miles of Mars observed by HiRISE, seeing details as small as a desk.  To watch the tutorial video and download the free HiView application, go...

Excellent launch precision for NASA's Mars Science Laboratory mission has forestalled the need for an early trajectory correction maneuver, now not required for a month or more. That first of six planned course adjustments during the 254-day journey from Earth to Mars had originally been scheduled for 15 days after the mission's Nov. 26 launch on a United Launch Alliance Atlas V rocket. Now, the correction maneuver will not be performed until later in December or possibly...

Mars Reconnaissance Orbiter Catches Mars Sand Dunes In Motion
2011-11-18 04:15:49

Images from NASA's Mars Reconnaissance Orbiter (MRO) show sand dunes and ripples moving across the surface of Mars at dozens of locations and shifting up to several yards. These observations reveal the planet's sandy surface is more dynamic than previously thought. "Mars either has more gusts of wind than we knew about before, or the winds are capable of transporting more sand," said Nathan Bridges, planetary scientist at the Johns Hopkins University's Applied Physics Laboratory in Laurel,...


Word of the Day
cruet
  • A vial or small glass bottle, especially one for holding vinegar, oil, etc.; a caster for liquids.
This word is Middle English in origin, and ultimately comes from the Old French, diminutive of 'crue,' flask.
