Blacksburg VA (SPX) Oct 14, 2004 - A Ph.D. student at Virginia Tech has research published this week in Nature that shows Mars probably had liquid water at some point, but likely for only a short time, geologically speaking.
Paris (ESA) Oct 12, 2004 - This image, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, shows a part of the southern highlands of Mars, called Promethei Terra.
Pasadena CA (JPL) Oct 12, 2004 - After working on Mars for three times as long as its primary three-month mission, Spirit is healthy and currently investigating the rock called Tetl in the Columbia Hills. In the language of the ancient Mayans, tetl means stone.
Los Alamos NM (SPX) Oct 11, 2004 - University of California scientists working at Los Alamos National Laboratory, along with a scientist from Indiana University have devised a method for determining whether sulfate salts can account for evidence of water on Mars. The work could pave the way to a better understanding of the martian environment and the history of water on Mars.
Moffett Field CA (SPX) Oct 11, 2004 - Opportunity may attempt to leave Endurance crater via a route marked as the Escape Hatch, if scientists and engineers consider it safe after taking a closer look.
Pasadena CA (JPL) Oct 08, 2004 - NASA's Spirit and Opportunity have been exploring Mars about three times as long as originally scheduled. The more they look, the more evidence of past liquid water on Mars these robots discover. Team members reported the new findings at a news briefing today.
Paris, France (ESA) Oct 08, 2004 - Most Mars Express scientific payload operations were suspended between 22 August and 27 September, due to a period of solar conjunction. During this time, however, radio science (MaRS) experiments of the solar corona were carried out. On the egress from conjunction all spacecraft systems were nominal.
Moffett Field CA (SPX) Oct 08, 2004 - NASA's Spirit and Opportunity have been exploring Mars about three times as long as originally scheduled. The more they look, the more evidence of past liquid water on Mars these robots discover. Team members reported the new findings at a news briefing today.
Bloomington IN (SPX) Oct 07, 2004 - Epsom-like salts believed to be common on Mars may be a major source of water there, say geologists at Indiana University Bloomington and Los Alamos National Laboratory. In their report in this week's Nature, the scientists also speculate that the salts will provide a chemical record of water on the Red Planet.
Paris, France (ESA) Oct 06, 2004 - This image, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, shows the Ophir Chasma, a northern part of the Valles Marineris canyon.
Paris, France (ESA) Oct 06, 2004 - This image, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, shows the Claritas Fossae tectonic grabens and part of the Solis Planum plains.
Pasadena CA (SPX) Oct 05, 2004 - Engineers on NASA's Mars Exploration Rover team are investigating possible causes and remedies for a problem affecting the steering on Spirit.
Pasadena CA (JPL) Oct 01, 2004 - Spirit has successfully transitioned back to normal operations from conjunction operations, when Mars and Earth were on opposite sides of the Sun. During conjunction (sols 244 through 255), engineers and scientists did not attempt normal operations due to the low probability of successful communications.
Houston (SPX) Sep 30, 2004 - It will be drilling for information first, then for resources, though oil is not likely to be among exploration targets.
Pasadena CA (JPL) Sep 28, 2004 - NASA's Mars Global Surveyor, starting its third mission extension this week after seven years of orbiting Mars, is using an innovative technique to capture pictures even sharper than most of the more than 170,000 it has already produced.
Paris, France (ESA) Sep 28, 2004 - Recent results from the ASPERA-3 instrument on board Mars Express confirm that a very efficient process is at work in the Martian atmosphere, which could explain the loss of water. Water is believed to have once been abundant on the Red Planet. Professor Rickard Lundin, leader of the ASPERA-3 team, describes these findings in a paper published in the latest issue of 'Science'.
