NASA.Curiosity Uncovers Underground Lake.Dec 2013

NASA’s Curiosity rover has dug below the Martian surface, and for the first time uncovered direct evidence of what used to be a freshwater lake. There is no water left where the lake once was, but drill tests and chemical analysis of fine-grained rocks by the Curiosity robot’s science tools suggest conditions were right for the lake to have once supported microbial life, perhaps as long as 3.6 billion years ago.

NASA’a latest findings provide the strongest evidence to-date that Mars could have held life to take hold, according to the report in the journal Science :: Read the full article »»»»


Mars, A Little Like Hawaii

Cankler Science News - NASA - Mars Curiosity, Landscape Like HawaiiNASA’s superneat Mars rover Curiosity has found soil that bears a striking resemblance to volcanic sand in Hawaii. In the first study of the red planet’s soil, Curiosity determined the grains have crystals similar to basaltic soils found in volcanic regions on Earth.

The rover uses an X-ray imager to reveal the atomic structures of crystals in the Martian soil, the first time the technology – x-ray diffraction – has been used to analyse soil beyond our planet.

“The mineralogy of Mars’s soil has been a source of conjecture until now,” Curiosity scientist David Vaniman said, from the Planetary Science Institute.”This interest isn’t just academic,” he added. “Soils on planets’ surfaces are a reflection of surface exposure processes and history, with information on present and past climates.”

The minerals were identified in the first sample of Martian soil ingested recently by the rover. Curiosity used its Chemistry and Mineralogy instrument – CheMin – to obtain the results, which are filling gaps and adding confidence to earlier estimates of the mineralogical makeup of the dust and fine soil widespread on the Red Planet.

NASA plan to use the information about Mars’s minerals to figure out if the planet most like Earth in the solar system could have supported and preserved microbial life :: Read the full article »»»»
