From orbit aboard the Landsat 9 satellite, the Thermal Infrared Sensor 2, or TIRS-2, will measure the temperature of Earth's land surfaces, detecting everything from a smoldering wildfire, to the amount of irrigation used on crop fields, to wispy clouds that are all but invisible to other instruments. First, however, it had to survive tests that simulated the harsh environment of space.

This month, TIRS-2 successfully passed the stringent 12-week testing process at NASA's Goddard Space Flight Center in Greenbelt, Maryland. It was shipped to Northrop Grumman's facility in Arizona, where it and the Operational Land Imager 2 will be assembled onto the Landsat 9 spacecraft. Landsat 9 is a joint effort of NASA and the U.S. Geological Survey.
