Temperature and Winds for InSight

File:MSL Rover Environmental Monitoring Station Crop.PNG

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.[http://adsabs.harvard.edu/abs/2015EGUGA..17.2571V The TWINS Instrument On Board Mars Insight Mission] Velasco, Tirso, and Rodríguez-Manfredi, Jose A., EGU General Assembly 2015, held 12–17 April 2015 in Vienna, Austria. id.2571. April 2015 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.[https://link.springer.com/article/10.1007/s11214-018-0543-0 Atmospheric Science with InSight] Spiga, A., Banfield, D., Teanby, N.A. et al., Space Science Reviews 2 October 2018 214:109 {{doi|10.1007/s11214-018-0543-0}} 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.

The sensors include thermometers, and an anemometer to measure wind speed and direction twice per second. Additional sensors are the InSight FluxGate (IFG) magnetometer provided by University of California, Los Angeles (UCLA) to measure the direction and magnitude of magnetic fields such as those caused by the Martian ionosphere; and a highly sensitive pressure sensor (barometer) from Jet Propulsion Laboratory (JPL).{{cite news|url=http://www.space.com/26820-nasa-mars-insight-mission-planet-history.html|title=NASA's Next Mars Lander Will Peer Deep Into Red Planet's History: Here's How|last=David|first=Leonard|date=15 August 2014|publisher=Space.com|access-date=16 August 2014}}{{cite conference

Wind, temperature, pressure and magnetometer data is used to understand the local wind behavior at the landing site to help understand and interpret SEIS data. At the same time, the lander uses its cameras to document cirrus clouds that develop high above Elysium Planitia, any instances of fog that appear along the ground, as well as dust devils.[https://www.msn.com/en-ca/weather/topstories/nasa-insight-to-give-us-our-best-look-yet-at-mars-weather/ar-BBPZJcd NASA InSight to give us our best look yet at Mars weather] The Weather Network 22 November 2018 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.

TWINS on InSight is part of what is called the Auxiliary Payload Sensor Suite, forming a "weather station" which components include:[https://arc.aiaa.org/doi/pdf/10.2514/6.2016-2592 Operations of the SEIS Seismometer Onboard the 2016 Mars InSIght Mission] Charles Yana, Aurélie Moussi, Agnès Jullien1.
