Pure science is amazing.
NASA's Mars Science Lab has been sitting on Mars for 52 days and has found tiny round pebbles - supporting the idea of a former stream running on the surface of Mars.
"This is something that would have required thousands of years, if not a million or more years, to form," says Mars Science Laboratory project scientist John Grotzinger of Caltech.
The gravels in conglomerates at both outcrops range in size from a grain of sand to a golf ball. Some are angular, but many are rounded.
"The shapes tell you they were transported and the sizes tell you they couldn't be transported by wind. They were transported by water flow," said Curiosity science co-investigator Rebecca Williams of the Planetary Science Institute in Tucson, Ariz.
