Martian Rock Arrangement Not Alien Handiwork
Calgary, Canada (SPX) Jan 13, 2009At first, figuring out how pebble-sized rocks organize themselves in evenly-spaced patterns in sand seemed simple and even intuitive. But once Andrew Leier, an assistant geoscience professor at the U of C, started observing, he discovered that the most commonly held notions did not apply. And even more surprising, was that his findings revealed answers to NASA's questions about sediment tr ... more Dawn Making Steady Progress To Next Asteroid Flyby 
Pasadena CA (JPL) Jan 13, 2009Having fulfilled all of its assignments for 2008, the Dawn spacecraft has been unusually quiescent recently. While its operators on faraway Earth have no shortage of work, the probe patiently coasts in its orbit around the Sun, awaiting a brief encounter with Mars on February 17, which will steer it into a new orbit. On October 31, Dawn completed nearly all the ion thrusting that had been ... more Study: Pebbles can move against wind 
Calgary, Alberta (UPI) Jan 8, 2009Pebbles that become part of clastic rocks in places like Arizona's Lower Antelope Canyon don't move with the wind but against it, a geosciences professor said. Rather than being pushed into formations, the pebbles, or clasts, have the loose sand around them removed by the wind, Andrew Leier of the University of Calgary said in the journal Geology. The sand removal causes scour-pi ... more Human Spaceflight To Mars Proposed Using Combination Of Space Shuttles 
Hartford CT (SPX) Jan 09, 2009Veteran inventor, business pioneer, futurist, and entrepreneur, Eric Knight, unveiled today his concept to enable the human exploration of Mars in a handful of years - instead of the 20-year timetable proposed by NASA and other space authorities. Knight describes his concept in a thought paper entitled: "Mars on a Shoestring: A novel method to transport humans to Mars based on a pair of ... more A Change Of Seasons On Mars 
Pasadena CA (JPL) Jan 08, 2009Summer turned to autumn for the Phoenix Mars Lander on December 26, 2008. This image, taken on December 21 by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter, shows the lander during the last waning days of northern hemisphere summer. The image was acquired at 3:31 pm Local Mars Time when the sun was 14-degrees above the horizon. The ima ... more |

Pasadena CA (JPL) Jan 03, 2009NASA rovers Spirit and Opportunity may still have big achievements ahead as they approach the fifth anniversaries of their memorable landings on Mars. Of the hundreds of engineers and scientists who cheered at NASA's Jet Propulsion Laboratory in Pasadena, Calif., on Jan. 3, 2004, when Spirit landed safely, and 21 days later when Opportunity followed suit, none predicted the team would stil ... more NASA describes final moments of Columbia tragedy 
Washington (AFP) Dec 31, 2008The crew of the doomed shuttle Columbia was violently spun around in the cabin as the spacecraft disintegrated on reentry, NASA said Tuesday in its final report on the 2003 tragedy that includes safety recommendations. The 400-page report took four years to complete and its conclusions will be used in configuring the future Orion spacecraft that will eventually replace the US space agency's ... more Mars rovers roll on after five years 
Pasadena, Calif. (UPI) Jan 3, 2008 The unmanned rovers Spirit and Opportunity are showing serious signs of wear after an astounding five years roaming Mars, U.S. space agency officials say. Scientists initially thought the remote-controlled machines would last only three months in Mars' freezing climate, said John Callas, rover project manager at the National Aeronautics and Space Administration's Jet Propulsion laborato ... more ISRO Eyes Lunar Landing In 2012 And Mars Mission In 2013 
Bangalore, India (PTI) Dec 29, 2008Buoyed by the success of Chandrayaan-I, Indian space scientists now plan to conquer new frontiers by sending a robot on moon in 2012 and a spacecraft to Mars the following year which will also see an Indian astronaut in space. Indian Space Research Organisation has lined up a slew of missions which also include landing a spacecraft on an asteroid and sending a probe to fly past a co ... more |

Boulder CO (SPX) Dec 17, 2008Picture a ball. It's an ordinary ball in every way except that it is roughly 4,300 miles in diameter and is moving through the cold of space some 35 million miles from Earth, and hurtling around the sun in just less than two Earth years. This is Mars. After a first glance at the Martian surface, one may quickly notice two striking global-scale features. The first is the three-mile ... more Phoenix Site On Mars May Be In Dry Climate Cycle Phase 
Pasadena CA (SPX) Dec 16, 2008The Martian arctic soil that NASA's Phoenix Mars Lander dug into this year is very cold and very dry. However, when long-term climate cycles make the site warmer, the soil may get moist enough to modify the chemistry, producing effects that persist through the colder times. Phoenix found clues increasing scientists' confidence in predictive models about water vapor moving through the soil ... more Mars Reconnaissance Orbiter Completes Prime Mission 
Pasadena CA (SPX) Dec 12, 2008NASA's Mars Reconnaissance Orbiter has completed its primary, two-year science phase. The spacecraft has found signs of a complex Martian history of climate change that produced a diversity of past watery environments. The orbiter has returned 73 terabits of science data, more than all earlier Mars missions combined. The spacecraft will build on this record as it continues to examine Mars ... more UA Projects Make Time List Of Top Science Discoveries 
Tempe AZ (SPX) Dec 12, 2008Two international science projects - one led by The University of Arizona, and one with considerable UA involvement - lead Time Magazine's list of Top 10 Scientific Discoveries, crowning a year of unprecedented science achievement for Arizona's land grant university. Time ranked the Large Hadron Collider - the massive particle acclerator straddling the Swiss-French border - at the top of ... more
