Statements about relative humidity do not jive with the record (Updated 4/7/2014).

On 4/9/2013 a statement appeared on FoxNews.Com about relative humidity at MSL. It went as follows:

       The Curiosity rover team reported the new results today (April 8) at the 2013 European Geosciences Union General Assembly in Vienna, where scientists also provided other updates about the rover's recent discoveries.

       For example, Curiosity's onboard weather station, known as REMS (for Rover Environmental Monitoring Station) has shown that humidity varies from place to place along the robot's route inside Mars' huge Gale Crater. REMS' observations are the first systematic measurements of humidity on the Martian surface, researchers said.

FACT: Not one single daily report for MSL weather issued by the REMS Team between August 22, 2012 and April 3, 2014 included any figure for relative humidity. As is seen with the examples below, all reports simply indicated --% for relative humidity or "Value not abailable.". Ashima Research chose to reproduce none of the relative humidity figures (really, lack thereof) on any of its reports taken from the REMS Team.

On June 27, 2013 the information below appeared on the REMS Team website.The graph below was also on the site, although we have cleaned up the fonts /text for clarification purposes. The relative humidity figures offered do not match an of the daily weather reports by the REMS Team, which continues to list all RH data as --%.

4.08.2013 Humidity in Gale Crater: Scant and VariableThis graphic tracks the maximum relative humidity and the temperature at which that maximum occurred each Martian day, or sol, for about one-fourth of a Martian year, as measured by the Remote Environmental Monitoring Station (REMS) on NASA's Curiosity Mars rover. These are the first systematic measurements of humidity on Mars. The data are graphed by sol number (starting with Curiosity's landing day as Sol 0), for a period from mid-August 2012 to mid-February 2013, corresponding to late winter through late spring in Mars' southern hemisphere. Four vertical lines on the graph mark progress points of the rover's traverse. While air temperature is not strongly tied to the rover's location, REMS has measured significantly different relative humidity in the different terrain units where the rover has been. All of the sites along the rover's traverse are extremely dry compared with Earth. Image Credit: NASA/JPL-Caltech/CAB(CSIC-INTA)/FMI/Ashima Research
