Ice Found in Mercury's Polar Regions

New Evidence for Ice on Mercury





Nov. 29, 2012:  New data from NASA's MESSENGER spacecraft suggest that there's enough ice on Mercury to encase the entire US capitol.

"The new data indicate the water ice in Mercury's polar regions, if spread over an area the size of Washington, D.C., would be more than 2 miles thick," said David Lawrence, a MESSENGER participating scientist at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., and lead author of one of three papers describing the findings in the online edition of Science Express.

Yellow shows the locations of bright polar deposits imaged by Earth-based radar. Updated from N. L. Chabot et al., Journal of Geophysical Research, 117, doi: 10.1029/2012JE004172 (2012). [more]
