ICESat-2 Prelaunch

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.
