Contour merging and attribution tools for ArcMap 10.1

13 September 2013

Ever need to clean and attribute scanned contours? Once the scan has been converted to vector lines (e.g. using ArcScan or GDAL), you may find these two ArcMap 10.1 add-ins helpful for merging and semi-automatically attributing the contour lines. The first tool, Iterative Self Select Intersected,… Read More

Sol 388 Update On Curiosity From USGS Scientist Ken Herkenhoff: New Record Drive

12 September 2013

I'm back from a week's vacation, catching up on everything that MSL has been doing. A new record for drive distance was set last week, 141 meters! Driving this far required lots of autonomous navigation, which left little time for science observations. Last weekend's plan included contact… Read More

Magellan SAR and synthetic stereo mosaics by quadrangle

9 September 2013

The Magellan SAR and Synthetic Stereo Mosaics were created back in 2002 by Vicki Hansen and Duncan Young at the University of Minnesota, Duluth. These are just visual Jpegs and currently do not have geospatial headers for mapping applications. Description: synthetic aperture radar (SAR, cycles 1,… Read More

Sol 382 Update On Curiosity From USGS Scientist Ken Herkenhoff: Onward to the Mountain

4 September 2013

Autonomous navigation continues to work well, allowing longer drives into areas not visible from the previous rover location. Today the view ahead is good enough that we are planning to drive over 100 meters, with the last ~45 meters using AutoNav. But driving this far leaves very little time… Read More

Sol 380 Update On Curiosity From USGS Scientist Ken Herkenhoff: Labor Day

31 August 2013

The Sol 379 drive went well, and the rover is in a safe configuration for arm deployment. So we are planning 3 sols today (to get the rover through the Labor Day holiday), including drop-off of sample to SAM and overnight analysis, followed by a drive on the last sol. We packed some more… Read More

New Name for a Crater on Mars

30 August 2013

The IAU Working Group for Planetary System Nomenclature has approved the name Artik for a crater on Mars. For more information, see the map of MC-29 in the Gazetteer of Planetary Nomenclature.

Sol 379-380 Update On Curiosity From USGS Scientist Ken Herkenhoff: Hectic Day

30 August 2013

Autonomous navigation continues to work well, and Curiosity completed another long drive on Sol 378. However, the left rear wheel ended up on a ~6 cm rock, which is larger than allowed for safe deployment of the arm. The concern that the wheel might slip off the rock while the arm is moving… Read More

Magmatic Water Found in Lunar Rocks

27 August 2013

Scientists, including USGS Astrogeology Team Member, Justin Hagerty, have detected magmatic water — water that originates from deep within the Moon's interior — on the surface of the Moon. These findings, published in the August 25 issue of Nature Geoscience, represent the first such… Read More

Sol 374 Update On Curiosity From USGS Scientist Ken Herkenhoff: Going Over the Hill

26 August 2013

The Sol 374 drive, including the AutoNav portion, went very well, so an even longer drive is planned for Sol 376. For the first time AutoNav will be used to drive 10 meters over the hill, or beyond the area imaged in stereo by the Navcams after the Sol 374 drive. If the AutoNav software… Read More
