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.

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.

TL;DR: The observations suggest that individual lakes were stable on the ancient surface of Mars for 100 to 10,000 years, a minimum duration when each lake was stable both thermally (as liquid water) and in terms of mass balance (with inputs effectively matching evaporation and loss of water to colder regions).

TL;DR: The first laser-induced breakdown spectrometer (LIBS) was used on the Mars Science Laboratory (MSL) rover Curiosity for remote compositional information using the first LIBS on a planetary mission, and provided sample texture and morphology data using a remote micro-imager.

TL;DR: Wiens et al. as mentioned in this paper reported on the development, integration, and testing of the Mast-Unit and summarized some key characteristics of ChemCam, which consists of a Mast-unit (laser, telescope, camera, and electronics) and a Body-Unit (spectrometers, digital processing unit, and optical demultiplexer).
