Friday 31st August Sol 25

We now have a weather report for Gale Crater courtesy of the REM instrument.  You can see the extreme day-night ‘diurnal’ variation in temperature that is characteristic of Mars, down to -70C and just reaching 0C at noon.  The Rover Environmental Monitoring Station (REM) instruments on the mast and rover deck, are now giving regular reports on atmospheric pressure, humidity, ultraviolet radiation  at the Martian surface, wind speed (from booms on the rover Mast) and direction, air temperature, and ground temperature around the rover.  This information will help us get a better understanding of the Mars climate. 

You can see today’s weather for Mars provided by the Spanish team here:
