Humidity measurement devices for Mars


The Finnish Meteorological Institute (FMI) is delivering pressure and humidity measuring devices based on Vaisala’s technology to NASA’s Mars 2020 Rover.

NASA’s next mission to Mars will take Vaisala’s innovative technology to the surface of the red planet. The devices are provided by the Finnish Meteorological Institute as part of the Spanish MEDA (Mars Environmental Dynamic Analyzer) device package, which will be installed in the Mars 2020 Rover.  The Rover will also carry Vaisala’s newest and most advanced pressure and humidity sensors, which have never been used on Mars terrain before.

FMI’s instruments will measure the pressure and humidity of the atmosphere of Mars. Final touches to the devices have been made and they will be handed over to NASA later this year, where they will be tested with the MEDA package’s main computer.

“We are very proud to be able to contribute to the study of Mars,” said Liisa Åström, Vice President Products and Systems, at Vaisala. “The sensors’ long-term stability and accuracy, as well as their ability to tolerate dust, chemicals, and harsh environmental conditions, makes them suitable for the very demanding measurement needs on Mars.”
