All Martian weather, all the time!

Mars has an amazing variety of weather. Currently, we have three “weather satellites” and a surface weather station sending us all sorts of information back about Martian meteorology. Right now, we’re going to spend most of our time on this site talking about the Rover Environmental Monitoring Station (REMS) on the Curiosity (Mars Science Laboratory) rover. But you should definitely check out the Mars Climate Sounder and Mars Color Imager aboard the Mars Reconnaissance Orbiter, and the Thermal Emission Spectrometer aboard the Mars Odyssey orbiter. Together, the orbiter and surface observations provide crucial information about how the atmosphere and climate of Mars function – information that is vital for understanding the physics of climate at work on this alien world.

Curiosity and REMS

On August 5, 2012 Curiosity landed in Gale Crater. The Rover Environmental Monitoring Station aboard Curiosity is now collecting information on winds, temperatures, UV levels, and – with sensors provided by the Finnish Meteorological Institute: pressure and humidity. It is still very early in the mission, and you can follow along with some of the people involved over on the blog. When things settle into an operational mode, we hope to provide you with a feed of weather information from REMS on our data page – there should also be an iPhone and Android app associated with this in the next few weeks / month.

A word of thanks

The REMS system represents a huge development effort from the team at the Centro de Astrobiología in Spain and at the Finnish Meteorological Institute. Ashima Research has put this site together to help share REMS’ story on the surface of Mars, but this is not an official REMS page and is a purely voluntary effort. Head over to CAB or FMI to checkout the official REMS sites from the people who actually built and operate the instrument.

None of the Martian weather systems would be possible without the vision and effort of JPL/NASA. The official JPL Mars Program website is a great place to start exploring Mars.
