Mars methane detection and variability at Gale crater
Curiosity confirms the presence and variability of atmospheric methane, implying episodic production from an unknown source, and reports of plumes or patches of methane in the martian atmosphere that vary over monthly time scales have defied explanation. Expand
Organic molecules in the Sheepbed Mudstone, Gale Crater, Mars
Chlorinated hydrocarbons identified in the Sheepbed mudstone by SAM are the reaction products of Martian chlorine and organic carbon derived from Martian sources or exogenous sources such as meteorites, comets, or interplanetary dust particles. Expand
Transient liquid water and water activity at Gale crater on Mars
Liquid water on equatorial Mars is inconsistent with large-scale climatic conditions. Humidity and temperature measurements by the Curiosity rover support the formation of subsurface liquid brines byExpand
Evidence for indigenous nitrogen in sedimentary and aeolian deposits from the Curiosity rover investigations at Gale crater, Mars
The detection of nitrate in both wind-drifted fines (RN) and in mudstone (JK, CB) is likely a result of N2 fixation to nitrate generated by thermal shock from impact or volcanic plume lightning on ancient Mars. Expand
Habitability: A Review.
This review on habitability defines it as the ability of an environment to support the activity of at least one known organism and adopts a binary definition of "habitability" and a "habitable environment". Expand
REMS: The Environmental Sensor Suite for the Mars Science Laboratory Rover
The Rover Environmental Monitoring Station (REMS) will investigate environmental factors directly tied to current habitability at the Martian surface during the Mars Science Laboratory (MSL) mission.Expand
Possible physical and thermodynamical evidence for liquid water at the Phoenix landing site
[1] The objective of the Phoenix mission is to determine if Mars' polar region can support life. Since liquid water is a basic ingredient for life, as we know it, an important goal of the mission isExpand
Background levels of methane in Mars’ atmosphere show strong seasonal variations
In situ measurements at Gale crater made over a 5-year period by the Tunable Laser Spectrometer on the Curiosity rover show large seasonal variation in the background and occurrences of higher temporary spikes that are consistent with small localized sources of methane released from martian surface or subsurface reservoirs. Expand
Observations and preliminary science results from the first 100 sols of MSL Rover Environmental Monitoring Station ground temperature sensor measurements at Gale Crater
We describe preliminary results from the first 100 sols of ground temperature measurements along the Mars Science Laboratory's traverse from Bradbury Landing to Rocknest in Gale. The groundExpand
Stability of liquid saline water on present day Mars
[1] Perchlorate salts (mostly magnesium and sodium perchlorate) have been detected on Mars' arctic soil by the Phoenix lander, furthermore chloride salts have been found on the Meridiani and GusevExpand
