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...

First Analyses Of ChemCam Laser Has Beautiful Results

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...

New research shows that hostile conditions on Mars were much worse 600,000 years ago than they are today, with evidence suggesting the red planet once had a much dustier, stormier atmosphere. NASA's Mars Reconnaissance Orbiter (MRO) discovered that the total amount of atmosphere on Mars changes significantly as the tilt of the planet's axis varies.  The process can affect the stability of liquid water -- if it exists on the surface "“ and can also increase the frequency and...
