TL;DR: The geologic record at Meridiani Planum suggests that conditions were suitable for biological activity for a period of time in martian history.
Journal ArticleDOI
Oxidation of the Ediacaran Ocean
TL;DR: High-resolution carbon isotope and sulphur isotope records from the Huqf Supergroup, Sultanate of Oman, that cover most of the Ediacaran period indicate that the ocean became increasingly oxygenated after the end of the Marinoan glaciation and allow us to identify three distinct stages of oxidation.
Journal ArticleDOI

TL;DR: The Curiosity rover discovered fine-grained sedimentary rocks, which are inferred to represent an ancient lake and preserve evidence of an environment that would have been suited to support a martian biosphere founded on chemolithoautotrophy.
Journal ArticleDOI
Stromatolites in precambrian carbonates : evolutionary mileposts or environmental dipsticks ?
TL;DR: Application of a process-based approach has shown that stromatolites were originally formed largely through in situ precipitation of laminae during Archean and older Proterozoic times, but that younger ProTerozoic strom atolites grew largely through the accretion of carbonate sediments, most likely through the physical process of microbial trapping and binding.

TL;DR: The Curiosity rover has a designed lifetime of at least one Mars year (∼23 months) and drive capability of up to 20 km as discussed by the authors, and is a scaled version of the Mars Exploration Rovers (MER) Spirit and Opportunity and the Mars Pathfinder Sojourner.
