United Launch Alliance launches Delta II with NASA's ICESat-2

United Launch Alliance (ULA) has announced its final Delta II rocket launched NASA´s Ice, Cloud and land Elevation Satellite-2 (ICESat-2) spacecraft from Space Launch Complex-2 on Sept. 15, the company said.

Delta II rocket first launched on Feb. 14, 1989.

From its origin as the launch vehicle for the first Global Positioning System (GPS) satellites to NASA´s Earth observing, science and interplanetary satellites — including Mars rovers Spirit and Opportunity — to vital commercial communication and imaging satellites, the Delta II rocket has justly earned its place in space history.

ICESat-2, with its single instrument, the Advanced Topographic Laser Altimeter System (ATLAS), will provide scientists with height measurements to create a global portrait of Earth´s third dimension, gathering data that can precisely track changes of terrain including glaciers, sea ice, forests and more. Northrop Grumman built the spacecraft. In addition to ICESat-2, this mission includes four CubeSats which will launch from dispensers mounted to the Delta II second stage.

This mission launched aboard a Delta II 7420-10 configuration rocket, which included a 10-foot-diameter payload fairing (PLF). The booster for this mission is powered by the RS-27A engine and the second stage is powered by the AJ10-118K engine.

United Launch Alliance is the nation´s most experienced and reliable launch service provider. ULA has successfully delivered more than 125 satellites to orbit that aid meteorologists in tracking severe weather, unlock the mysteries of our solar system, provide critical capabilities for troops in the field and enable personal device-based GPS navigation.
