Threatening Conditions For Rovers In Giant Martian Dust Storm
Pasadean CA (SPX) Aug 30, 2007The mighty Mars rovers Spirit and Opportunity continue to persevere in brutal conditions, as revealed in images of the sun they are sending home. The images show how opaque the Martian atmosphere has been in the face of a raging, two-month dust storm. To understand the gravity of the storm, engineers and astronomers monitor the situation by examining the images of the sun and measuring the ... more HiRISE Confirms Existence of 'Pit Craters' On Mars 
Tuscon AZ (SPX) Aug 30, 2007The High Resolution Imaging Experiment (HiRISE) has confirmed that a dark pit seen on Mars in an earlier HiRISE image really is a vertical shaft that cuts through lava flow on the flank of the Arsia Mons volcano. Such pits form on similar volcanoes in Hawaii and are called "pit craters." The HiRISE camera, orbiting the red planet on NASA's Mars Reconnaissance Orbiter, is the most ... more Calculating The Biomass Of Martian Soil 
Giessen, Germany (SPX) Aug 29, 2007A new interpretation of data from NASA's Viking landers indicates that 0.1% of the Martian soil tested could have a biological origin. This new interpretation of results from NASA's 1976 Viking missions could have important implications for the search for life in our Solar System. Dr Joop Houtkooper of the University of Giessen, Germany, believes that the subfreezing, arid Martian surface ... more Airplane Monitors Great Lakes Algae 
Cleveland OH (SPX) Aug 29, 2007A rare bird has been flying over the Great Lakes recently, and it isn't migrating or searching for prey. This hawkeyed species is a Learjet aircraft outfitted with an advanced imaging system. Engineers at NASA's Glenn Research Center in Cleveland modified the plane to help the National Oceanic and Atmospheric Administration (NOAA) monitor algae in western Lake Erie and Lake Huron's Saginaw Bay. ... more Recon Orbiter Camera Issue Resolved As 3000th Image Comes Down From Mars 
Pasadena CA (JPL) Aug 24, 2007Diagnostic tests and months of stable, successful operation have resolved concerns raised early this year about long-term prospects for the powerful telescopic camera on NASA's Mars Reconnaissance Orbiter. The High Resolution Imaging Science Experiment (HiRISE) camera on the orbiter has now taken more than 3,000 images of Mars, resolving features as small as a desk in targeted areas covering ... more |

Cape Canaveral, Florida (AFP) Aug 21, 2007NASA looked cautiously to its next mission due in October after the US shuttle Endeavour returned safely to Earth Tuesday despite damage to its underside. "We are still pointing for October, we still have time," the space agency's launch director Mike Leinbach told reporters at the Kennedy Space Center in Florida after the landing. ... more US shuttle makes textbook return landing 
Cape Canaveral, Florida (AFP) Aug 21, 2007US shuttle Endeavour returned safely to Earth Tuesday, despite damage to its underside, after a 13-day mission in which the first teacher in space gave lessons to children back home. "You have given a new meaning to higher education," joked astronaut Chris Ferguson, as he welcomed back the five-man, two-woman crew including Endeavour astronaut Barbara Morgan, the first teacher in space. ... more Hurtling Toward Mars 
Huntsville AL (MSFC) Aug 22, 2007Earth and Mars are converging, and right now the distance between the two planets is shrinking at a rate of 22,000 mph--or about 25 miles per sentence. Ultimately, this will lead to a close approach in late December 2007 when Mars will outshine every star in the night sky. Of a similar encounter in the 19th century, astronomer Percival Lowell wrote the following: ... more Dust From Martian Sky Accumulates On Solar Panels 
Pasadena CA (JPL) Aug 22, 2007Even though the Martian sky above Gusev Crater continued to clear, solar power levels on NASA's Spirit rover remained fairly constant as dust settling from the atmosphere accumulated on top of the solar panels. Activities remained restricted. Measurements of atmospheric opacity, known as Tau, dropped from 3.6 on Martian day, or sol, 1283 (Aug. 12, 2007) to 3.3 on sol 1286 (Aug. 16, 2007) ... more |

Moscow, Russia (RIA Novosti) Aug 15, 2007Solar energy supplies most of power in spacecraft nowadays. Although the efficiency of solar cells has grown substantially recently, they have reached the limit of their development and can supply electricity only in near-Earth orbits and for satellite-borne equipment. Such large-scale projects as the exploration of the Moon or a manned mission to Mars require nuclear power plants. ... more India Wants To Launch First Reusuable Space Launcher By 2010 
Bangalore (RIA Novosti) Aug 15, 2007India is planning to launch a reusable spacecraft for the first time in 2010 and to send a mission to Mars as early as 2012, a senior space official said Monday. India has been successfully developing its space program in recent years, regularly launching satellites using its own booster rockets. "Our target [for the first launch] is before 2010," the Press Trust of India news agency quoted ... more New Clues To Early Sol 
Toronto, Canada (SPX) Aug 14, 2007A University of Toronto-led study has uncovered tiny zircon crystals in a meteorite originating from Vesta (a large asteroid between Mars and Jupiter), shedding light on the formation of planetesimals, small astronomical objects that form the basis of planets. To date, studying zircons in eucrites - meteorites formed by volcanic activity - has been difficult due to impact- induced fracturi ... more Keeping The Plates Of Planet Earth Well Oiled 
Paris, France (ESF) Aug 14, 2007Earth's surface is a very active place; its plates are forever jiggling around, rearranging themselves into new configurations. Continents collide and mountains arise, oceans slide beneath continents and volcanoes spew. As far as we know Earth's restless surface is unique to the planets in our solar system. So what is it that keeps Earth's plates oiled and on the move? Scientists think tha ... more
