How Cutting-Edge Technology & Science Are Powering The Future TPM Idealab
Chief scientist Steve Squyres has a likely explanation. He said in a presentation last week that one of Opportunity's wheels probably kicked up the rock, which then slid into its field of view.
Early testing of the "jelly" part of the rock revealed characteristics unlike any other rock the rover has discovered during its decade on Mars. The rock is high in sulfur and magnesium, and scientists are still trying to figure out why.
