Science Benefits From Diverse Landing Area Of NASA Mars Rover
NASA’s Curiosity rover is revealing a great deal about Mars, from long-ago processes in its interior to the current interaction between the Martian surface and atmosphere.
Examination of loose rocks, sand and dust has provided new understanding of the local and global processes on Mars. Analysis of observations and measurements by the rover’s science instruments during the first four months after the August 2012 landing are detailed in five reports in the Sept. 27 edition of the journal Science.
A key finding is that water molecules are bound to fine-grained soil particles, accounting for about 2 percent of the particles’ weight at Gale Crater where Curiosity landed. This result has global implications, because these materials are likely distributed around the Red Planet.
Curiosity also has completed the first comprehensive mineralogical analysis on another planet using a standard laboratory method for identifying minerals on Earth. The findings about both crystalline and non-crystalline components in soil provide clues to the planet’s volcanic history.
