The report comes by way of the rover’s principal investigator, geologist John Grotzinger of Caltech, who said that Curiosity has uncovered exciting new results from a sample of Martian soil recently scooped up and placed in the Sample Analysis at Mars (SAM) instrument.
“This data is gonna be one for the history books. It’s looking really good,” Grotzinger told NPR in an segment published Nov. 20. Curiosity’s SAM instrument contains a vast array of tools that can vaporize soil and rocks to analyze them and measure the abundances of certain light elements such as carbon, oxygen, and nitrogen – chemicals typically associated with life.
The mystery will be revealed shortly, though. Grotzinger told Wired through e-mail that NASA would hold a press conference about the results during the 2012 American Geophysical Union meeting in San Francisco from Dec. 3 to 7. Because it’s so potentially earth-shaking, Grotzinger said the team remains cautious and is checking and double-checking their results. But while NASA is refusing to discuss the findings with anyone outside the team, especially reporters, other scientists are free to speculate.
ScienceDaily (Oct. 12, 2012) — The first Martian rock NASA’s Curiosity rover has reached out to touch presents a more varied composition than expected from previous missions. The rock also resembles some unusual rocks from Earth’s interior.
The rover team used two instruments on Curiosity to study the chemical makeup of the football-size rock called “Jake Matijevic” (matt-EE-oh-vick). The results support some surprising recent measurements and provide an example of why identifying rocks’ composition is such a major emphasis of the mission. Rock compositions tell stories about unseen environments and planetary processes.
“This rock is a close match in chemical composition to an unusual but well-known type of igneous rock found in many volcanic provinces on Earth,” said Edward Stolper of the California Institute of Technology in Pasadena, who is a Curiosity co-investigator. “With only one Martian rock of this type, it is difficult to know whether the same processes were involved, but it is a reasonable place to start thinking about its origin.”
The Nasa rover Curiosity has beamed pictures back from the red planet that appear to show the remnants of an ancient stream which once ‘ran vigorously’ on the surface of Mars.
The discovery of bedrock and pebbles, which appear to indicate there was once fast moving water on the planet, was described by the mission’s chief scientist as ‘exciting’.
Pebbles, that appear to have been rounded off by water, have offered the most convincing evidence yet that there was water on the surface of Mars.
NASA Mars Rover Opportunity Reveals Geological Mystery: Spherical Objects Unlike Previously Found ‘Blueberries’
ScienceDaily (Sep. 14, 2012) — NASA’s long-lived rover Opportunity has returned an image of the Martian surface that is puzzling researchers.
Spherical objects concentrated at an outcrop Opportunity reached last week differ in several ways from iron-rich spherules nicknamed “blueberries” the rover found at its landing site in early 2004 and at many other locations to date.
Opportunity is investigating an outcrop called Kirkwood in the Cape York segment of the western rim of Endeavour Crater. The spheres measure as much as one-eighth of an inch (3 millimeters) in diameter. The analysis is still preliminary, but it indicates that these spheres do not have the high iron content of Martian blueberries.
“This is one of the most extraordinary pictures from the whole mission,” said Opportunity’s principal investigator, Steve Squyres of Cornell University in Ithaca, N.Y. “Kirkwood is chock full of a dense accumulation of these small spherical objects. Of course, we immediately thought of the blueberries, but this is something different. We never have seen such a dense accumulation of spherules in a rock outcrop on Mars.”
