At Space Launch Complex 2 at Vandenberg Air Force Base in California, technicians install a poly picosatellite orbital deployer, or P-POD container, with tiny satellites called CubeSats inside, onto the direct mate adapter of the United Launch Alliance Delta II rocket, on Aug. 31, 2018. NASA’s Ice, Cloud and land Elevation Satellite-2 (ICESat-2) is ready for launch aboard the final 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.
