Flowing lava can carve or build paths very much like the riverbeds and canyons etched by water, and this probably explains at least one of the meandering channels on the surface of Mars. These results were presented on March 4, 2010 at the 41st Lunar and Planetary Science Conference by Jacob Bleacher at NASA's Goddard Space Flight Center, Greenbelt, Md. Whether channels on Mars were formed by water or by lava has been debated for years, and the outcome is thought to influence the likelihood...

Near the center of a Martian crater about the size of Connecticut, hundreds of exposed rock layers form a mound as tall as the Rockies and reveal a record of major environmental changes on Mars billions of years ago. The history told by this tall parfait of layers inside Gale Crater matches what has been proposed in recent years as the dominant planet-wide pattern for early Mars, according to a new report by geologists using instruments on NASA's Mars Reconnaissance Orbiter. "Looking at the...

PASADENA, Calif., Sept. 24 /PRNewswire-USNewswire/ -- NASA's Mars Reconnaissance Orbiter has revealed frozen water hiding just below the surface of mid-latitude Mars. The spacecraft's observations were obtained from orbit after meteorites excavated fresh craters on the Red Planet. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) Scientists controlling instruments on the orbiter found bright ice exposed at five Martian sites with new craters that range in depth from...

NASA's Jet Propulsion Laboratory in Pasadena, Calif., will host a media teleconference at noon PDT on Thursday, Sept. 24, to discuss new research results from NASA's Mars Reconnaissance Orbiter. The findings will be reported in Friday's edition of the journal Science. NASA will stream audio from the teleconference online. The teleconference participants are: - Ken Edgett, team member, Context Camera, Malin Space Science Systems, San Diego - Shane Byrne, team member, High Resolution Imaging...

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...

Heading into a period of the Martian year prone to major dust storms, the team operating NASA's twin Mars rovers is taking advantage of eye-in-the-sky weather reports. On April 21, Mars will be at the closest point to the sun in the planet's 23-month, elliptical orbit. One month later, the planet's equinox will mark the start of summer in Mars' southern hemisphere. This atmospheric-warming combination makes the coming weeks the most likely time of the Martian year for dust storms severe...

Researchers using a powerful instrument aboard NASA's Mars Reconnaissance Orbiter have found a long sought-after mineral on the Martian surface and, with it, unexpected clues to the Red Planet's watery past. Surveying intact bedrock layers with the Compact Reconnaissance Imaging Spectrometer for Mars, or CRISM, scientists found carbonate minerals, indicating that Mars had neutral to alkaline water when the minerals formed at these locations more than 3.6 billion years ago. Carbonates, which...

The Phoenix Lander over the weekend successfully weathered a regional dust storm that temporarily lowered its solar power, and the team is back investigating the Red Planet's northern plains. The increasing opacity in the atmosphere from the storm decreased the power reaching the Phoenix's solar arrays. So on Martian days, or sols, 135-136 of the mission (Oct. 11-12), Phoenix scientists and engineers curtailed many of the lander's science activities, such as collecting some data from its...

About four billion years ago, there were lakes on Mars which may have been fed by short-lived rivers that were, in turn, fed by precipitation. These lakes filled craters that were formed by the impact of meteorites. Water accumulated in places where rivers broke through the crater rims. Deltas were formed at the mouths of the rivers, similar to how they are formed where rivers flow into lakes or seas on Earth. These are the findings of an international team of researchers led by Ernst Hauber...

New observations from NASA's Mars Reconnaissance Orbiter indicate that the crust and upper mantle of Mars are stiffer and colder than previously thought.The findings suggest any liquid water that might exist below the planet's surface, and any possible organisms living in that water, would be located deeper than scientists had suspected."We found that the rocky surface of Mars is not bending under the load of the north polar ice cap," said Roger Phillips of the Southwest Research Institute in...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
