Delta II ICESat-2 Encapsulation

The first half of the United Launch Alliance Delta II payload fairing is secured around NASA's Ice, Cloud and land Elevation Satellite-2 (ICESat-2) on Sept. 4, 2018, at Space Launch Complex 2 at Vandenberg Air Force Base in California. The satellite is being prepared for its scheduled launch on the final Delta II rocket. ICESat-2 will measure the height of a changing Earth, one laser pulse at a time, 10,000 laser pulses a second. The satellite will carry the Advanced Topographic Laser Altimeter System (ATLAS). ICESat-2 will help scientists investigate why, and how much our planet's frozen and icy areas, called the cryosphere, are changing in a warming climate.
