A flatbed truck arrives at Vandenberg Air Force Base in California, carrying the payload fairing for the United Launch Alliance (ULA) Delta II rocket that will launch NASA's Ice, Cloud and land Elevation Satellite-2 (ICESat-2). 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 our planet's frozen and icy areas, called the cryosphere, is changing in a warming climate. ICESat-2 is scheduled to launch on the final ULA Delta II rocket later this year.

NASA's Ice, Cloud and land Elevation Satellite-2 (ICESat-2) arrives in its shipping container aboard a heavy transport truck on June 12, 2018, at Vandenberg Air Force Base in California. ICESat-2 was shipped from the Northrop Grumman facility in Gilbert, Arizona, where it was built and tested. The satellite is scheduled to launch Sept. 12, 2018, on the final United Launch Alliance Delta II rocket from Space Launch Complex-2 at Vandenberg. 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. ICESat-2 will help scientists investigate why, and how much our planet's frozen and icy areas, called the cryosphere, is changing in a warming climate.
An emblem signifying the 381st flight of the United Launch Alliance Delta family is seen on the Delta II rocket, with the NASA Ice, Cloud and land Elevation Satellite-2 (ICESat-2) onboard, Wednesday, Sept. 12, 2018, at Vandenberg Air Force Base in California. The first Delta I was launched in May 1960. A star traditionally was placed on the rocket to recognize each mission. For the final Delta II, stars were sent to team members and partners throughout the nation. This rocket boasts more than 150 stars with over 800 signatures of people who have been part of the Delta II program. The ICESat-2 mission will measure the changing height of Earth's ice.
