Space Probe Finds Ice In Mercury's Craters

NASA Researchers say they have identified traces of ice in craters on Mercury, seen here in this Oct. 8, 2008, image from the Messenger spacecraft. Mercury is not the first planet to come to mind if you were searching for ice in the solar system. After all, the surface temperature across most of the planet is hot enough to melt lead. But at the poles on Mercury it's a different story. Almost no sun reaches the poles, and as a result, temperatures can drop to less than -100 degrees Fahrenheit. Now, three papers in the journal Science suggest there really is ice at the bottom of craters near the poles on Mercury.

| -0.322896 | "It could be coming from the interior, because every planet contains a little bit of water in the mantle," says Neumann. |

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.

On the poles of our solar system's innermost planet, where temperatures can drop to -100 degrees Fahrenheit, researchers have identified water ice and organic "goo," most likely deposited there by comets that crashed into the planet.
