Is There Life On Mars - Ask A Magnet
Moffett Field CA (SPX) May 06, 2008Between three and four billion years ago, Mars was a lot like Earth. Both planets are believed to have had surface water. Those similarities make it a prime candidate for extraterrestrial life. "The assumption is that if bacterial life emerged on Earth at that time, then why not on Mars?" says Soon Sam Kim, principal member of technical staff at NASA's Jet Propulsion Laboratory. Mars may a ... more Spirit In A Catch-22: Stay Awake Or Sleep 
Pasadena CA (SPX) May 06, 2008Spirit's Tau measurements of atmospheric dust have remained steady, but solar array input has dropped a bit to 235 watt-hours per sol. Spirit still has enough energy to squeeze in Moessbauer studies of iron-bearing minerals at a time of year when the rover's handlers expected Spirit to be concerned only with survival. At present, the rover's target of scientific interest is a soil exposure ... more Glaciers Reveal Martian Climate Has Been Recently Active 
Providence RI (SPX) Apr 30, 2008The prevailing thinking is that Mars is a planet whose active climate has been confined to the distant past. About 3.5 billion years ago, the Red Planet had extensive flowing water and then fell quiet - deadly quiet. It didn't seem the climate had changed much since. Now, in a research article that graces the May cover of Geology, scientists at Brown University think Mars' climate has ... more New Online Map Reveals Evidence Of The Forces That Once Shaped Mars 
Laurel MD (SPX) Apr 30, 2008A new online map lets visitors explore Mars' past through a collection of high-resolution observations from one of the most powerful spectrometers ever sent to the Red Planet. Evidence of ancient bodies of water, flowing rivers and groundwater peeks out from beneath layers of hardened magma and dust -- testaments to Mars' progression through wet, volcanic and dry eras. The data come from ... more Artificial Intelligence Boosts Science From Mars 
Paris, France (ESA) Apr 30, 2008Artificial intelligence (AI) being used at the European Space Operations Centre is giving a powerful boost to ESA's Mars Express as it searches for signs of past or present life on the Red Planet. Since January 2005, Mars Express has been using its sophisticated instruments to study the atmosphere, surface and subsurface of Mars, confirming the presence of water and looking for other signatures ... more |

Pasadena CA (JPL) Apr 23, 2008Despite a slight increase in atmospheric opacity caused by dust, Spirit is still enjoying higher-than-expected energy levels for this time of year. Solar array input has been approximately 240 watt-hours per Martian day, or sol (100 watt-hours is the amount of energy needed to light a 100-watt bulb for one hour). Clear skies have had the unfavorable effect, however, of causing a drop in ... more Driving on Mars Is Hard 
Pasadena CA (JPL) Apr 23, 2008This week Opportunity demonstrated the challenges of operating a vehicle on the surface of another planet. The rover is en route to Cape Verde to acquire high-resolution images of the layering in the rocks. To get there, Opportunity must cross some sandy stretches. Before entering the sandy areas, Opportunity will need to stop and take a "toe dip'' -- that is, drive forward a short distance and ... more Astronauts upbeat after hard 'ballistic' landing 
Star City, Russia (AFP) April 21, 2008The first South Korean in space together with the American and a Russian who accompanied her said on Monday they were recovering well after a gruelling "ballistic" descent to Earth. Yi So-Yeon, who returned from the International Space Station (ISS) on Saturday in an irregular landing that subjected the crew to huge gravitational forces, said there had been nothing to worry about either ... more Mars Technology On Board A Balloon To Study The Earth's Atmosphere 
Kiruna, Sweden (SPX) Apr 22, 2008"From Mars to the Earth and back" is the theme when the Swedish Institute of Space Physics (IRF), the Swedish Space Corporation (SSC) and University of Bern in Switzerland build and launch a mass spectrometer on a stratospheric balloon from SSC's operational facility Esrange Space Center in Kiruna. The project is called MEAP (Mars Environment Analogue Platform) and will be carried out ... more |

Moscow (XNA) Apr 14, 2008Russia is going to create a manned assembly complex in orbit, the chief of the Federal Space Agency Anatoly Perminov said here on Saturday. "We shall create this complex in order to make dockings in orbit, build craft there and send them to the Moon, Mars and other planets," Perminov was quoted by the Itar-Tass news agency as telling a new briefing. "This proposal was on the wh ... more Russia Continues Flight Simulation Experiments For Mars-500 
Moscow (RIA Novosti) Apr 16, 2008Four volunteers will spend ten days in a compression chamber with a reduced oxygen level as preparation for Mars-500, a Russian ground-based experiment to simulate a flight to Mars. A spokesman for the Moscow-based Russian Institute of Medical and Biological Issues, which runs the project, said that four healthy men will be held in a chamber with the pressure equivalent to being five meters ... more Missions To Mars 
Paris, France (SPX) Apr 15, 2008The European Space Agency (ESA) has chosen the GSI accelerator facility to assess radiation risks that astronauts will be exposed to on a Mars mission. GSI was selected because its accelerator is the only one in Europe able to create ion beams similar to those found in space. To determine possible health risks of manned space flights, scientists from all over Europe have been asked to investigat ... more Opportunity Continues Reading The Story In The Rocks 
Pasadena CA (SPX) Apr 14, 2008Opportunity has finished grinding into the surface and acquiring microscopic images of a rock target informally named "Gilbert," at the bottom of the alcove inside "Victoria Crater" known as "Duck Bay." The rover is in the middle of a campaign to study the composition of the exposed interior of the rock using both the Mossbauer and alpha-particle X-ray spectrometers. Some time next week ... more
