Curiosity update, sols 631-644: On the road again

Posted by Emily Lakdawalla on 2014/05/30 06:51 CDT | 6 comments

The last couple of weeks have seen Curiosity return to the business of making steady headway toward Murray Buttes and, beyond them, Mount Sharp. Eight of the last 14 sols have seen drives ranging in length from 30 to 104 meters, racking up a total of more than half a kilometer. They are now occasionally working a shortened planning timeline that allows them to squeeze more drive sols into Curiosity's schedule.

The value of a Guest Investigator program for Dawn

Posted by Anne Verbiscer on 2014/05/23 09:20 CDT | 1 comments

NASA selected 21 Participating Scientists to join the Dawn team in 2010, prior to Dawn's arrival at Vesta in 2011. Since that time, Dawn Participating Scientists have made enormous contributions to the mission, as they do for most other NASA missions. But the status of a Participating Scientist program for Dawn at Ceres has been in doubt.
