ICESat-2 will provide scientists with height measurements that create a global portrait of Earth’s third dimension, gathering data that can precisely track changes of terrain including glaciers, sea ice, forests and more.

The Ice, Cloud and land Elevation Satellite-2 is slated to launch in September to measure the height of Earth’s surface, particularly the changing polar ice. To do that, it uses a laser instrument called the Advanced Topographic Laser Altimeter System, or ATLAS, that precisely times how long it takes light particles to bounce off Earth and return to the satellite.

ATLAS was designed, built and tested at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. The spacecraft bus, with its solar panels, navigation components and more, was built at Orbital ATK’s facility in Gilbert, Arizona. To deliver the instrument safely to the spacecraft for assembly and testing, the ATLAS team developed special procedures for packing, transporting and monitoring the sensitive hardware.
