Buffeted by ethereal whirlwinds and twisters, the Curiosity Mars rover is wrapping up initial soil analysis operations at a sandy drift where it's been parked for more than a month, project scientists said Thursday. The rover is now being prepared to move on in search of suitable targets for a compact rock drill, the final major sample acquisition system to be tested. Ashwin Vasavada, the deputy project scientist for the Mars Science Laboratory rover at the Jet Propulsion Laboratory in Pasadena, Calif. , told reporters that Curiosity's robot arm had completed five scoops of martian soil, using the sandy material to clean and scour the sampling system and to deposit samples into both of the rover's main internal instrument suites. The Chemistry and Mineralogy package, or CheMin, uses X-ray diffraction to identify and analyze the minerals in samples collected by Curiosity's robot arm.

We still would like to get a little further into this Glenelg region where we see this diversity of rocks and layered rocks and other really interesting terrain. And then we still have a goal in the next month or two of doing the big U-turn and heading up to Mount Sharp."

0.0611381"Most of what we've talked about on this mission is the ancient habitability of Mars," Vasavada said. "But we also have some pretty important goals on this mission of studying the modern environment. And it's a pretty dynamic environment. "If you were standing next to Curiosity, you'd realize you were on a planet with an atmosphere, an atmosphere that's thick enough that when the sun heats the ground every day, gusty winds rush up and down the slopes of Gale Crater and Mount Sharp and spawn whirlwinds that sweep across the landscape. But the atmosphere isn't thick enough to shield you from the harsh ultraviolet light and the natural high energy radiation coming in from space."

0"When you add up all those different contributions, you need to stay within your career limits," he said. "So over time, we're going to get those numbers. Since we've been on the surface, we have not yet seen a large solar flare or solar particle event like we saw during cruise (to Mars). When we do see one, that will be very interesting and very important."

Key:

  • Aggregate Sentiment is meant to be an indicator of an individual's overall sentiment.
  • The Mean is meant to be an indicator of an individual's average comment sentiment.
  • The Standard Deviation, when there are enough quotes, will indicate an individual's consistency of sentiment (i.e. a Standard Deviation of 0 would mean they were very consistent in their sentiment and 1 would mean they were very inconsistent).

Note that quote stats are likely to be meaningless beyond the aggregate score due to the tiny sample size. However, they are always provided just in case you find something useful there.
