Curiosity update: One Mars Year! Sols 662-670

Posted by Emily Lakdawalla on 2014/06/25 03:34 CDT | 2 comments

On Monday JPL put out a press release marking one year since Curiosity landed -- one Mars year, that is! There was a new version of the Kimberley self-portrait, and a video update on wheel wear testing. While we've been celebrating on Earth, Curiosity has been driving, driving, driving, on a new "safe transit route" taking her southward toward the black sand dunes ringing Mount Sharp.

Rosetta completes another rocket burn, spies decreasing activity on comet

Posted by Emily Lakdawalla on 2014/06/19 10:42 CDT

Rosetta has now completed its three largest rendezvous burns as it approaches ever closer to comet 67P/Churyumov-Gerasimenko. Beginning on July 2, Rosetta will now conduct weekly burns, through August 6. Meanwhile, the cometary activity of April and May has quieted again, leaving the comet looking smaller than it did before.

Curiosity update, sols 645-661: Driving, driving, driving

Posted by Emily Lakdawalla on 2014/06/16 04:44 CDT

Curiosity has been busy. The rover has traveled more than half a kilometer since my last update, making steady progress beyond the Kimberley toward Murray Buttes. There hasn't been much time for science, but they sneaked in an observation of a Mercury transit across the sun, and a neat MARDI video of the rover driving.

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 comment

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.

Venus Express science mission ends; aerobraking experiment beginning

Posted by Emily Lakdawalla on 2014/05/16 03:33 CDT | 4 comments

Venus Express, currently the only spacecraft orbiting our nearest planetary neighbor, will soon meet a fiery end in Venus' atmosphere. But its work isn't over yet. ESA will maneuver Venus Express to dip into the uppermost Venus atmosphere and study how the spacecraft responds to atmospheric pressure, giving ESA valuable experience in aerobraking.
