Field Report From Mars: Sol 3519 - December 18, 2013

Posted by Larry Crumpler on 2014/02/25 11:55 CST

Opportunity arrived at the location that has been the target of all this climbing since late last (Earth) summer. We will settle in for some detailed work on the outcrop here since this appears to be something different from the impact breccias that we have been seeing along the ridge crest.

Curiosity update, sols 540-8: New rules and longer drives

Posted by Emily Lakdawalla on 2014/02/20 05:53 CST | 3 comments

Curiosity has tested a new driving mode -- backwards -- and achieved their longest single-day drive in three months.
