Note for NASA Proposers, Geologic Mapping

21 February 2014

Proposed geologic mapping or topical science investigations of any planetary or satellite surface that are intended to result in the publication of a Scientific Investigations Map (SIM) by the U.S. Geological Survey (USGS) should check the relevant box on the proposal Cover Page and clearly… Read More

Sol 550 Update On Curiosity From USGS Scientist Ken Herkenhoff: Bungle Bungle

21 February 2014

The Sol 549 drive brought the rover close enough to the outcrop dubbed Bungle Bungle to allow MAHLI and APXS measurements, so the Sol 550 plan focuses on contact science. First, ChemCam will zap and image the outcrop, then the arm will be deployed. After the contact science has completed, the… Read More

Sol 549 Update On Curiosity From USGS Scientist Ken Herkenhoff: Low Outcrop

20 February 2014

The rover drove over 100 meters on Sol 548, so it is time for another full set of wheel images to monitor wear. Because the MAHLI wheel imaging sequences have been used many times before, it was a relatively easy day for me as MAHLI/MARDI uplink lead. After the wheel imaging is finished, the… Read More

Sol 548 Update On Curiosity From USGS Scientist Ken Herkenhoff: Driving Backwards

19 February 2014

Testing on Earth has shown that driving backward should reduce wear on the front and middle wheels, so the Sol 547 drive was the first long, 100 meters, backward drive. It went very well, and the terrain ahead looks good, so another long drive is planned for Sol 548, again mostly backward.

Sol 546 Update On Curiosity From USGS Scientist Ken Herkenhoff: Presidents Day

18 February 2014

Monday was a holiday (Presidents' Day) for some of us, but not for the MSL tactical team. The activities planned for last weekend went well, including a 47-meter drive, so the Sol 546 plan focused on imaging of the wheels at 4 positions.

Sol 544 - 545 Update On Curiosity From USGS Scientist Ken Herkenhoff: Busy Before Sunrise

14 February 2014

Another busy 2-sol plan--Sol 544 will begin with a bunch of MAHLI activities: Imaging of the inlet for SAM's tunable laser spectrometer, the standard wheel imaging, and images from various angles of a spot in front of the rover to measure the photometric behavior of the surface. The first and… Read More

First Global Geologic Map of Ganymede

12 February 2014

More than 400 years after its discovery by Galileo, the largest moon in the Solar System – Ganymede – has finally claimed a spot on the map. Read More. . . Also see the video on the multimedia library page.

Sol 542 - 543 Update On Curiosity From USGS Scientist Ken Herkenhoff: Fitting Everything In

12 February 2014

I'm SOWG Chair again for another 2-sol plan, and it's been a more hectic planning day. The Sol 540 drive went well, about 71 meters total. A shorter (~23 m) drive is planned for Sol 542, allowing some time for pre-drive targeted Mastcam stereo imaging and MAHLI images of the wheels. Because the… Read More

Sol 540 - 541 Update On Curiosity From USGS Scientist Ken Herkenhoff: Small Valley

11 February 2014

I'm SOWG Chair today for a 2-sol plan. Planning is restricted again, as we won't receive the data from Sol 540 until late Tuesday. So we're planning a ~73-meter drive on Sol 540 and untargeted remote science on Sol 541. Before the drive, we've planned big Mastcam mosaics of the walls of the… Read More
