The second stage of the United Launch Alliance Delta II rocket is lifted high up at the Vertical Integration Facility, at left, at Space Launch Complex 2 on June 21, 2018, at Vandenberg Air Force Base in California. The second stage will be attached to the top of the booster, or first stage of the rocket, which is being moved out of the Mobile Service Tower, at right. NASA's Ice, Cloud and land Elevation Satellite-2 (ICESat-2) will 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 a single instrument, the Advanced Topographic Laser Altimeter System.
