Beginning Jan. 18, NASA's Mars Odyssey orbiter will listen for possible, though improbable, radio transmissions from the Phoenix Mars Lander, which completed five months of studying an arctic Martian site in November 2008. The solar-powered lander operated two months longer than its three-month prime mission during summer on northern Mars before the seasonal ebb of sunshine ended its work. Since then, Phoenix's landing site has gone through autumn, winter and part of spring. The lander's...

RIVERSIDE, Calif., Oct. 23 /PRNewswire/ -- Vertigo, Inc., a subsidiary of HDT Engineered Technologies (HDT), was recognized by the National Aeronautics and Space Administration (NASA) for its contributions as members of the Mars Phoenix Lander Entry, Descent and Landing Team. The first in NASA's Scout Program, Phoenix was launched to Mars in 2007 to study the history of water and habitability potential in the Martian arctic's ice-rich soil. Dara Sabahi, Director at NASA's Jet...

New, three-dimensional imaging of Martian north-polar ice layers by a radar instrument on NASA's Mars Reconnaissance Orbiter is consistent with theoretical models of Martian climate swings during the past few million years. Alignment of the layering patterns with the modeled climate cycles provides insight about how the layers accumulated. These ice-rich, layered deposits cover an area one-third larger than Texas and form a stack up to 2 kilometers (1.2 miles) thick atop a basal deposit with...

Wind speeds and directions were measured for the first time in the Mars polar region using the Phoenix lander's Telltale instrument. Astronomers recorded Easterly winds of approximately 15-20 kilometers per hour during the martian mid-summer. When autumn approached, the winds increased and switched round to come predominantly from the West. While these winds appeared to be dominated by turbulence, the highest wind speeds recorded of up to nearly 60 kilometers per hour coincided with the...

Networks of giant polygonal troughs etched across crater basins on Mars have been identified as desiccation cracks caused by evaporating lakes, providing further evidence of a warmer, wetter martian past. The findings were presented today at the European Planetary Science Congress by PhD student Mr M Ramy El Maarry of the Max Planck Institute for Solar System Research. The polygons are formed when long cracks in the surface of the martian soil intersect. El Marry investigated networks of...

U.S. space agency scientists said the area where the Phoenix Mars Lander touched down last year might be a favorable environment for microbes. The NASA experts said their hypothesis was based on favorable chemistry and episodes with thin films of liquid water during ongoing, long-term climate cycles. Phoenix ended communications in November as the approach of the Martian winter depleted energy from its solar panels. Not only did we find water ice, as expected, but the soil chemistry and...

U.S. scientists say data from the Phoenix Mars Lander suggests parts of Mars resemble Earth, including landscape, history of water and weather conditions. Professor Mark Lemmon of Texas A&M University has been involved with Mars missions for years and he says NASA's Phoenix Mars Lander -- which touched down in May 2008 -- keeps revealing secrets about the planet. Phoenix landed in a place that has access to Martian ice, which is exciting by itself, Lemmon said. Phoenix was designed to...

Four papers in the journal Science this week offer new details about the history of water on Mars, gleaned from the 2008 NASA Phoenix Mars Mission that was operated from The University of Arizona.Peter H. Smith, a scientist with the UA Lunar and Planetary Laboratory and the mission's principal investigator, is the first author of "H2O at the Phoenix Landing Site" in Science. There are 35 co-authors from six countries on the paper. Smith and his group of scientists and students used the lander...

Researchers at the 40th Lunar and Planetary Science Conference in the Woodlands, Texas have been discussing the possibility that water may actually exist on Mars. It was previously assumed that water existed on the Red Planet only in the form of ice or vapor due to the low temperatures and atmospheric pressure. However, the recent discovery by NASA's Phoenix probe showing that perchlorate salts exist within the soil of Mars adds credence to the idea of liquid water on the planet. Some...

The U.S. space agency says martian soil its Phoenix Mars Lander collected this year is very cold and dry, but during climate cycles it might become moist. Phoenix found clues increasing scientists' confidence in predictive models about water vapor moving through the soil between the atmosphere and subsurface water-ice, the National Aeronautics and Space Administration said, noting the models predict the vapor flow can wet the soil when the tilt of Mars' axis, the obliquity, is greater than it...
