NASA Opportunity Rover Finishes Walkabout On Mars Crater Rim
"If you are a geologist studying a site like this, one of the first things you do is walk the outcrop, and that's what we've done with Opportunity," said Steve Squyres, the mission's principal investigator at Cornell University in Ithaca, N.Y. Coming up on its ninth anniversary, Opportunity still is a capable robotic explorer. It has been investigating a crater-rim site where observations from orbiting Mars spacecraft detected traces of clay minerals, which form under wet, non-acidic conditions that can be favorable for life. The rover's current activities were presented at the Fall Meeting of the American Geophysical Union in San Francisco. The rover team chose this site as a driving destination years earlier. The site is named Matijevic Hill in honor of the late Jacob Matijevic, who led the engineering team for the twin Mars exploration rovers Spirit and Opportunity for several years.

| 0.1664 | "newberries." "We don't know yet whether Whitewood Lake and Kirkland are from before or after the crater formed," he said. "One of the most important things to work out is the order and position of the rock layers to tell us the relative ages. We also need more work on the composition of Whitewater and debris shed by Whitewater to understand the clay signature seen from orbit, and on the composition of the newberries to understand how they formed." |

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.
