Sol 466-468 Update On Curiosity From USGS Scientist Ken Herkenhoff: Anniversary of Launch

26 November 2013

MSL launched from Florida two years ago today--I was pretty nervous that day, but the mission has obviously gone extremely well! Planning is restricted this week (results of the drive planned for Sol 465 will not arrive until tonight), so we are planning 3 sols of untargeted remote sensing to get… Read More

Sol 465: Update On Curiosity From USGS Scientist Ken Herkenhoff: the RTG

25 November 2013

I'm SOWG Chair again today, planning Sol 465, which includes the first drive since the electrical issue over a week ago. The change in power bus voltage appears to have been caused by an electrical short in the Radioisotope Thermoelectric Generator (RTG), the nuclear power source for the rover. … Read More

Sol 462-464 Update On Curiosity From USGS Scientist Ken Herkenhoff: Planning Resumed

22 November 2013

MSL science planning has resumed! Today we are planning 3 sols, with the focus on dropping more of the drill sample into 4 of SAM's cups, for future analysis. While the arm is out, we'll take MAHLI images of the rover wheels and a Mastcam image of the sample seive, for engineering assessment. … Read More

Sol 461 Update On Curiosity From USGS Scientist Ken Herkenhoff: Electrical Issue

20 November 2013

There will be no MSL science planning again today, as analysis of the recent electrical issue continues. We are hope to return to normal science operations on Friday, planning 3 sols for the weekend.

Sol 460 Update On Curiosity From USGS Scientist Ken Herkenhoff: Stand Down

19 November 2013

I was scheduled as MAHLI/MARDI uplink lead today, but there was nothing to do because all science planning is on hold while the power issue is being investigated. Because planning is restricted this week, diagnostic data acquired today will not be available in time for planning tomorrow. If the… Read More

Sol 458: Update On Curiosity From USGS Scientist Ken Herkenhoff: Murray Buttes

18 November 2013

The plan for last weekend included driving on 2 sols. Unfortunately, the first drive, on Sol 455, was aborted due to a wheel stall. There was also an electrical problem, so the Sol 458 plan will be devoted to getting the engineering data needed to recover from this problem. The rover is in a… Read More

Sol 453: Update On Curiosity From USGS Scientist Ken Herkenhoff: Deja Vu

14 November 2013

I was SOWG Chair again planning Sol 452, which was disappointing because it was basically a repeat of Sol 451. When the Sol 451 plan was run on the testbed, a potential problem was discovered and the decision was made at the last minute not to send it to the rover. The problem, which may have… Read More

Sol 451 Update On Curiosity From USGS Scientist Ken Herkenhoff: Recovering

12 November 2013

I'm SOWG Chair today, but focused on tomorrow's plan because Sol 451 is dedicated to recovering from last week's software anomaly. So far, the recovery is going well and we are planning to resume normal science operations on Sol 452. We have received lots of data acquired during the Cooperstown… Read More

Update On Curiosity From USGS Scientist Ken Herkenhoff: Flight Software Upgrades

7 November 2013

There are no science observations planned this week while the rover flight software is upgraded. This upgrade was planned well in advance, and if all goes well science and drive planning will resume on Monday.

Sol 441 - 443: Update On Curiosity From USGS Scientist Ken Herkenhoff: Deploying the Arm

1 November 2013

Planning started at 6:30 this morning to allow enough time to plan 3 sols before we have to send the command sequences to the rover by 19:00 this evening. The science theme groups requested lots of good observations, expecting that they wouldn't all fit into the plan. It was therefore a hectic… Read More
