Fluvial and lacustrine activity on layered deposits in Melas Chasma, Valles Marineris, Mars

[i] Valley networks on Mars are the most obvious features attesting that different geologic processes and possibly climatic conditions existed in the past. THEMIS images reveal valley networks within Melas Chasma, in Valles Marineris, a Hesperian-age canyon system. The valley networks in Melas Chasma are dense and highly organized, and the heads of the valleys are scattered at different elevati...

Mars Exploration Rover candidate landing sites as viewed by THEMIS

The analysis of six landing sites that were candidates for the two NASA Mars Exploration Rovers (MER) benefited from recently available image data from the Thermal Emission Imaging Spectrometer (THEMIS) onboard the 2001 Mars Odyssey spacecraft. The combination of daytime and nighttime thermal infrared images from THEMIS supplemented by additional data sets has lead to new or expanded insights i...

Extension across Valles Marineris and the Thaumasia “rift”, Mars

We calculate the amount of crustal stretching across the Valles Marineris and a large graben structure in the western Thaumasia region (the “Thaumasia graben” [1,2]). We measure vertical offsets in a set of transects using data obtained by the MOLA laser altimeter. Assuming a fault dip angle of 60°, correcting for landslide deposits, but ignoring other sediment cover, we obtain extension values...

Basal melting of snow on early Mars: A possible origin of some valley networks

[1] Valley networks appear to be cut by liquid water, yet simulations suggest that early Mars could not have been warmed enough by a CO2-H2O greenhouse to permit rainfall. The vulnerability of an early atmosphere to impact erosion, the likely rapid scavenging of CO2 from the atmosphere by weathering, and the lack of detection of weathering products all support a cold early Mars. We explore the ...
