Mars Rover Experiences Dust Devil
2012-11-15 14:44:39

Lee Rannals for redOrbit.com - Your Universe Online NASA announced on Thursday during a teleconference that its Curiosity rover has experienced its first whirlwind on Mars. Although the rover did not snap a photo of the whirlwind, Curiosity's Rover Environmental Monitoring Station (REMS) was able to help detect the dust devil. REMS detected brief dips in air pressure, along with a change in wind direction, leading NASA scientists to determine that there was a whirlwind passing by...

Curiosity Samples The Martian Atmosphere
2012-11-02 13:36:25

Lee Rannals for redOrbit.com - Your Universe Online NASA said on Friday that its Curiosity rover has helped determine Mars' atmosphere is 100 times thinner than Earth's. Curiosity has been performing scientific experiments while positioned at "Rocknest," a site near Gale Crater. While parked, the rover has ingested and analyzed samples of the atmosphere. Findings from the Sample Analysis at Mars (SAM) instruments onboard Curiosity suggest that a loss of a fraction of the atmosphere...

Climate Models Work For Mars Too

Lee Rannals for redOrbit.com - Your Universe Online According to a new study, scientific modeling methods that predicated climate change on Earth can also be used on Mars as well. Researchers from Planetary Science Institute in Tucson report they have found that an unusual concentration of glacial features on Mars matches predictions made by global climate computerized models, in terms of age and location. "Some public figures imply that modeling of global climate change on Earth is...

Mars Orbiter Sees 'Dry Ice' Snow On Mars
2012-09-12 04:45:09

Lee Rannals for redOrbit.com - Your Universe Online Although lately it has been snapping images of Curiosity and its landing remnants, NASA's Mars Reconnaissance Orbiter (MRO) data has given scientists the clearest evidence yet of carbon dioxide snowfalls on Mars. Frozen carbon dioxide, or "dry ice," requires temperatures of about negative 193 degrees Fahrenheit, which is considered colder than needed for freezing water. Carbon dioxide snow reminds scientists that although some parts...

PASADENA, Calif., Sept. 11, 2012 /PRNewswire-USNewswire/ -- NASA's Mars Reconnaissance Orbiter (MRO) data have given scientists the clearest evidence yet of carbon dioxide snowfalls on Mars. This reveals the only known example of carbon dioxide snow falling anywhere in our solar system.

Lee Rannals for redOrbit.com — Your Universe Online Researchers from the Niels Bohr Institute have dated climate history for Mars for the first time. The ice caps on Mars' poles are miles thick, composed of ice and dust and contain layers that can be seen in cliffs and valley slopes. The layers are believed to reflect past climate on Mars, in the same way that Earth's climate history can be seen from the ice caps on Greenland and Antarctica. The scientists were able to...

Mars Suffering Through 600 Million Year Drought
2012-02-04 04:46:30

According to new research, Mars may have been arid for over 600 million years, making it inhospitable for life to survive. Researchers spent three years analyzing data on Martian soil that was collected during the 2008 NASA Phoenix mission to Mars. Phoenix touched down in the northern arctic region of the Red Planet to look for signs that it was habitable to support life by analyzing ice and soil on the surface. They found that the surface of Mars has been arid for hundreds of...

Image 1 - NASA Missions To Invesitgate A Hostile Mars
2011-11-19 05:40:03

NASA said on Friday that it is planning new missions to Mars to investigate how the planet turned hostile. The space agency said it is planning two missions to the Red Planet, one that will roam the surface and another that will orbit the planet. "The Red Planet's thin atmosphere does little to shield the ground against radiation from the Sun and space," Bill Steigerwald of NASA's Goddard Space Flight Center said in a NASA press release. "Harsh chemicals, like hydrogen peroxide,...
