Mars Rover Curiosity Equipped with Vaisala's Pressure and Humidity Sensors
(Thomson Reuters ONE) -
Vaisala has a presence in examining the Martian atmosphere as the Mars Rover
Curiosity is equipped with Vaisala BAROCAP® and HUMICAP® pressure and humidity
sensors. The sensors are a part of instrumentation designed by the Finnish
Meteorological Institute (FMI), and they will be used to gather accurate
readings of pressure and humidity in the extreme environmental conditions of the
Martian atmosphere.
Vaisala has provided the project with standard Vaisala HUMICAP® humidity sensors
and specially customized Vaisala BAROCAP® pressure sensors. Both were put
through space qualification testing by FMI, to ensure they are suited to the
Martian atmosphere, in addition to which FMI made specific alterations and
modifications to the Vaisala BAROCAP® pressure sensors to meet the needs of the
mission.
Vaisala's technology will be used to compile time series on pressure and
humidity for the duration of the entire Mars Science Laboratory program, which
is one Mars year, 686 Earth days. FMI's instruments will also be used to look
for possible residues and evidence of water that may have filled the Gale crater
in the past. Furthermore, the rover will be making observations about the
structure, geology and environmental conditions of the area.
Vaisala has provided sensors to FMI's space exploration projects since 1988.
This is the fifth venture to space where FMI is applying Vaisala's technology.
"The Finnish Meteorological Institute benefits not only from the sensors but
also from Vaisala's scientific and technological knowhow. Our 24 years of
collaboration in space exploration projects is testament of this," says FMI's
Head of Radar and Space Technology, Ari-Matti Harri.
The Vaisala BAROCAP® and HUMICAP® sensor technologies are used in numerous
Vaisala products such as radiosondes, weather stations and other instruments.
Vaisala HUMICAP® Humidity and Temperature Probe HMP155 for reliable humidity and
temperature measurements. The HMP155 has a new generation Vaisala HUMICAP®180R
sensor that has excellent stability even in harsh environments thanks to solid
probe structure and maximum protection against liquid water, dust, and dirt.
Vaisala BAROCAP® Digital Barometer PTB330, a new generation barometer designed
for a wide range of demanding atmospheric pressure measurement. The pressure
measurement of the PTB330 is based on the Vaisala BAROCAP® silicon capacitive,
absolute pressure sensor that provides high measurement accuracy and excellent
long-term stability.
