Curiosity confirms the Martian origin of some meteors on Earth

Dear followers,

After the discovery of of water on Mars, few weeks ago, the Curiosity rover is still performing this work. Actually, while the NASA was out due to the shutdown during 2 weekend, the +NASA 's rover analysed the Martian atmosphere. These analyses confirm that some meteorites that have dropped to Earth really are from the Red Planet.

A key new measurement of the inert gas argon in Mars' atmosphere by the laboratory on-board the rover, provides the most definitive proof yet of the origin of Mars meteorites while at the same time giving a way to rule out Martian origin of other meteorites.

The Curiosity measurements do not directly measure the current rate of atmospheric escape, but NASA's next mission to Mars, the Mars Atmosphere and Volatile Evolution Mission (MAVEN), is designed to do so. This mission is being prepared at NASA’s Kennedy Space Center in Florida for a launch around November 18th 2013.

Water on Mars discovered by Curiosity

Dear followers,

few weeks after its first anniversary on the red planet, the NASA's rover Curiosity is still working.  The first scoop of soil analysed by the analytic suite in the belly of martian rover reveals that fine materials on the surface of the planet contain several percent water by weight. The scientists used the ChemCam, CheMin instruments, the Alpha Particle X-ray Spectrometer (APXS) and the Sample Analysis at Mars (SAM) suite aboard NASA’s Curiosity Rover to perform the analysis.

About 2 percent of the soil on the surface of Mars is made up of water, which is great resource, and interesting scientifically. The sample also released significant carbon dioxide,oxygen and sulfur compounds when heated.

The result were published in Science as one article in a five-paper special section on the curiosity mission.
