CAP CAN CANVERAL, Florida (AP) – And now, the weather on Mars: NASA's last lander offers daily reports on the cold winter of the red planet.
As early as Tuesday, NASA's jet propulsion laboratory displays the ups and downs in line, as well as the wind speed and atmospheric pressure of the InSight lander.
On Sunday, InSight recorded a high of 2 degrees Fahrenheit (minus 17 degrees Celsius) and a minus minus 138 degrees Fahrenheit (minus 95 degrees Celsius). Compare that with the coldest Sunday US weather: minus 27 degrees (minus 3 Celsius) in Taylor Park, Colorado.
Scientists need to know the local weather on Mars to determine if the InSight seismometer is recording real earthquakes or simply changes in wind or pressure.
InSight landed near the equator on Mars in November. NASA's Curiosity rover also provides weather updates, while wandering around Mars at around 550km.
