Multi-Tasking Rover Helps Pave The Way For Next Mars Mission
Pasadena CA (SPX) Mar 25, 2008Opportunity completed the first leg of a two-part drive toward an area of scientific interest known as "Gilbert" that involved moving backward in order to continue the drive without running into some unexpectedly deep soil to the rover's right. En route, Opportunity spent two Martian days acquiring compositional data from a rock exposure dubbed "Lyell-Exeter," measured argon gas in the Martian a ... more Spacewalkers test new shuttle repair techniques 
Washington (AFP) March 21, 2008Two astronauts returned from the void Friday after a spacewalk to test new repair techniques for the space shuttle's heat shield, crucial for a new mission to the orbiting Hubble Space Telescope. Astronauts Robert Behnken and Mike Foreman, who arrived at the International Space Station aboard the shuttle Endeavour last week, spent six hours and 24 minutes outside the ISS working on ... more Mars Salt Deposits Point To New Place In Hunt For Ancient Traces Of Life 
Tempe AZ (SPX) Mar 20, 2008Scientists using a Mars-orbiting camera designed and operated at Arizona State University's Mars Space Flight Facility have discovered the first evidence for deposits of chloride minerals - salts - in numerous places on Mars. These deposits, say the scientists, show where water was once abundant and may also provide evidence for the existence of former Martian life. ... more Salt Deposits May Have Evidence Of Life On Mars 
Washington (AFP) March 20, 2008US scientists have discovered salt deposits on the surface of Mars, indicating that water was once plenty and pointing sites that could provide evidence of past life, a study said Thursday. The deposits were discovered by a team of scientists led by Mikki Osterloo at the University of Hawaii using thermal images from the orbiting Mars Odyssey spacecraft, according to research in the March 21 ... more Frozen Life Cubes 
Moffett Field CA (SPX) Mar 18, 2008If extraterrestrial life exists in the solar system, there is a good chance that it will be discovered as frozen remains trapped in a block of ice. Mars's ice caps are one possible location. Another is the surface ice of Jupiter's moon Europa, which scientists believe harbors an ice-capped ocean. Scientists dream about bringing ice sample from Mars or Europa back to Earth for study. A robot ... more |

Greenbelt MD (SPX) Mar 14, 2008Little noticed by the general public, February 23rd was a special day in space exploration. For the first time in history, an all-woman team of scientists and engineers guided a major NASA mission-the Mars Exploration Rovers. "We were in control of Spirit's activities for the day," explains Barbara Cohen of the Marshall Space Flight Center who headed up the science team. "It was a milestone in ... more HiRISE Discovers A Possibly Once-Habitable Ancient Mars Lake 
Tucson AZ (SPX) Mar 07, 2008Scientists studying images from The University of Arizona-led High Resolution Imaging Experiment camera on NASA's Mars Reconnaissance Orbiter have discovered never-before-seen impact "megabreccia" and a possibly once-habitable ancient lake on Mars at a place called Holden crater. The megabreccia is topped by layers of fine sediments that formed in what apparently was a long-lived, calm lake ... more Europe Ready To Launch World's Latest Space Freighter 
Paris (AFP) March 6, 2008The most advanced robot freighter in space history is due for its maiden launch this weekend, crowning Europe's involvement in the troubled International Space Station. If all goes well, a beefed-up Ariane 5 rocket will blast off from French Guiana at 0339 GMT on Sunday, taking aloft a cylindrical craft the size of a London double-decker bus that will play a unique dual role of cargo ... more Mars And Venus Are Surprisingly Similar 
Paris, France (ESA) Mar 06, 2008Using two ESA spacecraft, planetary scientists are watching the atmospheres of Mars and Venus being stripped away into space. The simultaneous observations by Mars Express and Venus Express give scientists the data they need to investigate the evolution of the two planets' atmospheres. Scientists call this work comparative planetology. Mars Express and Venus Express are so good at it becau ... more |

Moffet Field CA (SPX) Mar 04, 2008"I admit I never actually wrote this goal into my grant," UC Berkeley Professor of Chemistry Richard Mathies told me, as one of his graduate students injected a drop of Zinfandel into Mathies's organic analyzer. "But it is an important demonstration" that the detector actually works. The device in Mathies's lab is a prototype of the Mars Organic Analyzer. Along with several other com ... more NASA Spacecraft Photographs Avalanches On Mars 
Pasadena CA (SPX) Mar 04, 2008A NASA spacecraft in orbit around Mars has taken the first ever image of active avalanches near the Red Planet's north pole. The image shows tan clouds billowing away from the foot of a towering slope, where ice and dust have just cascaded down. The High Resolution Imaging Experiment (HiRISE) on NASA's Mars Reconnaissance Orbiter took the photograph Feb. 19. It is one of approximately 2,400 ... more Liquid Water Found Flowing On Mars - Not Yet 
Tuscon AZ (SPX) Mar 04, 2008Liquid water has not been found on the Martian surface within the last decade after all, according to new research. The finding casts doubt on the 2006 report that the bright spots in some Martian gullies indicate that liquid water flowed down those gullies sometime since 1999. "It rules out pure liquid water," said lead author Jon D. Pelletier of The University of Arizona in Tucson. ... more Study casts doubt on Mars water find 
Tucson (UPI) Mar 03, 2008A U.S. scientist said high resolution images raise doubt that liquid water has been found on the surface of Mars. Jon D. Pelletier of The University of Arizona in Tucson said topographic data from the High Resolution Imaging Science Experiment camera on NASA's Mars Reconnaissance Orbiter shows that a bright streak in a gully on the side of a crater is probably not water. ... more
