ExoMars: CaSSIS sends first images from orbit

20161122_163828_north_of_da_vinci_PAN_1The Mars Camera, CaSSIS, on the ExoMars Trace Gas Orbiter captured its first high resolution images of the Red Planet last week. The Bernese camera worked almost perfectly and has provided spectacular views of the surface.

CaSSIS (Colour and Stereo Surface Imaging System) has been developed by a team from the University of Bern led by Prof. Nicolas Thomas from the Center of Space and Habitability (CSH). It was launched with the European Space Agency’s ExoMars Trace Gas Orbiter (TGO) on 14 March 2016. TGO entered orbit around Mars on 19 October. The onboard camera, CaSSIS, has returned its first images from orbit.

“The first images we received are absolutely spectacular – and it was only meant to be a test,” says Nicolas Thomas. (…)

TGO is currently in a highly elliptical orbit of just over 4 days duration. The spacecraft comes within 250 km of the surface for a very short period but then goes out to over 100’000 km from the planet. CaSSIS has imaged during two of these close approaches to test its capabilities and functions. The first approach occurred on 22 November.

“A lot of public attention has been on the failed landing of Schiaparelli, but TGO has been working really well so we have been extremely busy in the past month,” says Nicolas Thomas. [More at link, including video, and here]

THEMIS: Tectonics showcase in Sirenum Fossae

Tectonics showcase in Sirenum Fossae (THEMIS_IOTD_20161129)THEMIS Image of the Day, November 29, 2016. Today’s VIS image shows part of Sirenum Fossae, a large graben on the margin between Terra Sirenum and Daedalis Planum. Grabens are formed by the downward movement of material between parallel tectonic faults.

Curiosity update: Preparing to drill

FRB_533587517EDR_F0592830FHAZ00206M_Sol 1534, November 28, 2016, update by USGS scientist Lauren Edgar: Curiosity had a productive Thanksgiving weekend and now we are getting ready to drill at “Precipice.”  Sol 1534 begins with MAHLI imaging of the post-sieve dump pile from the previous drill sample (“Sebina”).  Then we have a short science block to acquire a ChemCam passive observation and a Mastcam multispectral observation of the dump pile.  In the afternoon the plan includes a CHIMRA “thwack” activity… [More at link]

HRSC: Adamas Labyrinthus

Adamas_LabyrinthusThis labyrinth-like system of troughs and plateaus was imaged by ESA’s Mars Express on 21 June 2016.

It shows part of a region known as Adamas Labyrinthus, which is found in Utopia Planitia in the northern lowlands of Mars. Here, the randomly shaped blocks vary in size from 5–20 km across and are separated by cross-cutting troughs with widths of up to 2 km.

The pattern is similar to that observed in some offshore locations on Earth, supporting an idea that the scene here results from the deposition of fine-grained sediments in an ocean.

The formation of such polygons with surrounding troughs has been attributed to a number of varied processes, including collapse under gravity, the expulsion of fluid from the porous sediments as they are being compacted, low friction between the sediments resulting in mass wasting, and local tectonic activity extending the blocks apart. The underlying topography of the surface below may also play a role. [More at link]

Opportunity: Pathway to the south

4566-navcamSol 4566, November 27, 2016. The rover’s Navcam shot a composite view (above) looking southward, the direction Opportunity is traveling. Then the Pancam, which gives a 3x “telescopic view” compared to the Navcam, took a series (below) showing the rocks and ground ahead in more detail. Click either image to enlarge it.

THEMIS: Dune field in Dulovo Crater

Dunes in Dulovo Crater THEMIS_IOTD_20161125)THEMIS Image of the Day, November 25, 2016. Today’s false color image shows the dunes on the floor of Dulovo Crater. The blue tint indicates that the sand grains are particles of basaltic rock.

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.
