TL;DR: In this paper, the Curiosity rover supported the formation of subsurface liquid brines by hydration of perchlorates during the night on equatorial Mars, which is inconsistent with large-scale climatic conditions.

TL;DR: In the first 100 Martian solar days (sols) of the Mars Science Laboratory mission, the Rover Environmental Monitoring Station (REMS) measured the seasonally evolving diurnal cycles of ultraviolet radiation, atmospheric pressure, air temperature, ground temperature, relative humidity, and wind within Gale Crater on Mars as discussed by the authors.
Journal ArticleDOI

TL;DR: The REMS-H measurement performance and initial observations during the first 100 MSL sols appear to be convincing and are aligned with earlier indirect observations of the total atmospheric precipitable water content.
Journal ArticleDOI

TL;DR: In this paper, the pressure measurement subsystem of the Mars Science Laboratory (MSL) Rover Environmental Measurement Station (REMS-P) performed accurate observations of the Martian atmospheric surface pressure.

TL;DR: In this article, the authors used a line-of-sight optical depth within Gale Crater and compared this optical depth to column optical depths obtained using Mastcam observations of the solar disc.
