The countdown is underway for the liftoff of NASA's Ice, Cloud and land Elevation Satellite-2 (ICESat-2) atop a United Launch Alliance Delta II rocket. Liftoff from Space Launch Complex 2 at Vandenberg Air Force Base in California is scheduled for 5:46 a.m. PDT (8:46 a.m. EDT). 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 a single instrument, the Advanced Topographic Laser Altimeter System. ICESat-2 will help scientists investigate why, and how much Earth's frozen and icy areas, called the cryosphere, is changing.
