Mars Inside And Out May Have Had Differing Geological Histories
2012-11-20 05:50:00

April Flowers for redOrbit.com - Your Universe Online A team of scientists led by the Carnegie Institution for Science recently studied the hydrogen in water from the interior of Mars and found that Mars was formed from similar building blocks to that of Earth. There are differences, however, in the later evolution of the two planets, which implies that terrestrial planets such as Earth have similar water sources — chondritic meteorites. Unlike Earth, however, rocks on Mars that...

HOUSTON, Nov. 19, 2012 /PRNewswire-USNewswire/ -- A team of NASA scientists and their colleagues have found evidence from meteorites that Mars and Earth had a similar origin, but then the two planets evolved quite differently. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Based on their analyses of two Martian meteorites, researchers in the Astromaterials Research and Exploration Science Directorate at NASA's Johnson Space Center have concluded that water in the Martian...

PASADENA, Calif., Nov. 2, 2012 /PRNewswire-USNewswire/ -- NASA's car-sized rover, Curiosity, has taken significant steps toward understanding how Mars may have lost much of its original atmosphere. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Learning what happened to the Martian atmosphere will help scientists assess whether the planet ever was habitable. The present atmosphere of Mars is 100 times thinner than Earth's. A set of instruments aboard the rover has ingested...

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...

Martian Meteorite Reveals Atmospheric Secrets
2012-10-12 04:47:23

April Flowers for redOrbit.com - Your Universe Online An international team of researchers is examining a meteorite that landed 14 months ago in the Moroccan desert for information about Mars. Traces of the Martian atmosphere were trapped in the Tissint meteorite, according to the study led by the University of Alberta. “Our team matched traces of gases found inside the Tissint meteorite with samples of Mars´ atmosphere collected in 1976 by Viking, NASA´s Mars lander...

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. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Frozen carbon dioxide, better known as "dry ice," requires temperatures of about minus 193 degrees Fahrenheit (minus 125 Celsius), which is much...

First Analyses Of ChemCam Laser Has Beautiful Results
2012-08-24 08:21:43

Curiosity beams back strong, clear data from ℠scour´ area on Martian surface Members of the Mars Science Laboratory Curiosity rover ChemCam team, including Los Alamos National Laboratory scientists, squeezed in a little extra target practice after zapping the first fist-sized rock that was placed in the laser´s crosshairs last weekend. Much to the delight of the scientific team, the laser instrument has fired nearly 500 shots so far that have produced strong, clear data...

Lee Rannals for RedOrbit.com New research suggests meteorites may be the culprit behind how methane became present in the atmosphere of Mars. Using meteorites found on Earth, researchers from the University of Edinburgh, the Max Planck Institute in Germany and Utrecht University set out to find how Mars' environment started hosting methane gas. The meteorite samples used landed on Earth 40 years ago, but Dr. Andrew McLeod, of the University of Edinburgh's School of GeoSciences told...

Image 1 - Mars Express Finds Water Supersaturation In Martian Atmosphere
2011-09-30 10:03:36

New analysis of data sent back by the SPICAM spectrometer on board ESA's Mars Express spacecraft has revealed for the first time that the planet's atmosphere is supersaturated with water vapor. This surprising discovery has major implications for understanding the Martian water cycle and the historical evolution of the atmosphere. Although numerous spacecraft have visited Mars over the past half a century, very few direct measurements of the vertical structure of the planet's atmosphere...
