Temperature and Winds for InSight

TWINS is based on the heritage from REMS (Rover Environmental Monitoring Station) on board the Curiosity rover, with enhanced performances in terms of dynamic range and resolution. TWINS provides continuous wind and air temperature measurements to help understand the seismic data from the SEIS instrument. While probing the internal structure of Mars is the primary scientific goal of the InSight mission, atmospheric science remains a key science objective. InSight will provide a continuous and higher-frequency record of pressure, air temperature and winds at the surface of Mars than previous in situ missions. With this data, scientists are able to gain even greater insights into Mars' weather and climate, supplementing what was collected by previous missions, and what is currently being gathered by the Curiosity rover about 600 km to the south. == Auxiliary Payload Sensor Suite (APSS) ==

TWINS on InSight is part of what is called the Auxiliary Payload Sensor Suite, forming a "weather station" which components include: • TWINS: Temperature and wind sensor developed by the Spanish Astrobiology Center (CAB), Madrid, Spain • IFG: InSight FluxGate magnetometer, developed by the University of California at Los Angeles (UCLA) ay USA • PS: Pressure sensor developed by the TAVIS company at USA • PAE: Electronics controlling the TWINS, PS and IFG sensors developed by JPL == See also ==
