Curiosity: Looking into Telegraph Peak drill hole

0911MH0004750000303057R00_DXXXSol 911, February 28, 2015. A nighttime LED image by MAHLI of the Telegraph Peak drill hole shows the “dry cement powder” color of the drill tailings and layers down in the hole itself. Part of the exposed wall shows a bright streak. The location of the drill hole is shown in the front Navcam image at lower right (arrow).

Long-runout landslides in Valles Marineris

iag-image-1Planetary Geomorphology Image of the Month, March 2015: Jessica Watkins (University of California, Los Angeles).

Long-runout (> 50 km) subaerial mass movements are rare on Earth but it is one of the most prominent geomorphic processes shaping Valles Marineris in equatorial Mars. It has occurred widely and nearly continuously within the canyon system over the past 3.5 billion years (Quantin et al., 2004).

There is a characteristic surface morphology exhibited by many Valles Marineris landslides despite their diverse ages. It consists of an (upslope) inner zone with rotated blocks, and a long-runout outer (or distal) zone, characterized by thin sheets spreading over 10s of km across the trough floor, marked by longitudinal grooves… [More at link]

THEMIS: Elysium Planitia crater false color

Crater in Elysium Planitia false color (THEMIS-IOTD_20150302)THEMIS Image of the Day, March 2, 2015. The THEMIS VIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create a false color image. These false color images may reveal subtle variations of the surface not easily identified in a single band image. Today’s false color image shows an unnamed crater in Elysium Planitia.

Curiosity update: ‘Drilling Telegraph Peak…’

0908MH0003990010302873C00_DXXX-br2Sol 908-913, February 27, 2015, update from USGS scientist Ryan Anderson: It’s been a busy week on Mars, as usual! The big activity in the Sol 908 plan was drilling at the target “Telegraph Peak”. After the drilling, on sol 909 ChemCam made measurements of the targets “Tapeats” and “Humbug”, and Mastcam took supporting images of those targets. Mastcam also took images of the fresh drill hole using…. [More at link]

Opportunity: Looking southeast

3944-4pancamASol 3944, February 27, 2015. For the last several sols, mission controllers have been using Opportunity’s Pancam (with all its filters) to take a full-color panorama from the head of Marathon Valley. This composite (click to open a larger version in a new tab) looks southeast and was taken through the left-side Pancam’s red-sensitive filter.

Curiosity drills Telegraph Peak target

pia19140-16NASA’s Curiosity Mars rover used its drill on Tuesday, Feb. 24 to collect sample powder from inside a rock target called “Telegraph Peak.” The target sits in the upper portion of “Pahrump Hills,” an outcrop the mission has been investigating for five months. The Pahrump Hills campaign previously drilled at two other sites. The outcrop is an exposure of bedrock that forms the basal layer of Mount Sharp….

The rover team is planning to drive Curiosity away from Pahrump Hills in coming days, exiting through a narrow valley called “Artist’s Drive,” which will lead the rover along a strategically planned route higher on the basal layer of Mount Sharp… [More at link]
