NASA's Ice, Cloud and land Elevation Satellite-2 (ICESat-2), inside its protective canister, is lifted and moved to a transport trailer inside the Astrotech Space Operations high bay at Vandenberg Air Force Base in California, on Aug. 25, 2018. The satellite will be transported to Space Launch Complex 2 where it will be hoisted up by crane and attached to the United Launch Alliance Delta II rocket. Launch is scheduled for Sept. 15, 2018. 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.
