Опубликовано: 15 сент. 2018 г.

United Launch Alliance's final Delta II rocket (7420-10C) launched ICESat-2 from Space Launch Complex-2, Vandenberg Air Force Base, California, on 15 September 2018, at 13:02 UTC (06:02 PDT; 09:02 EDT). The Ice, Cloud and land Elevation Satellite-2, or ICESat-2, has a single instrument, the Advanced Topographic Laser Altimeter System, or ATLAS, to measure the elevation of ice sheets, sea ice, forests and more in unprecedented detail. The official designation of the two-stage launch vehicle for the mission is Delta 7420-10C. It had a kerosene and liquid oxygen first stage powered by an Aerojet Rocketdyne RS-27A main engine, four ground-lit, side-mounted Northrop Grumman Graphite Epoxy Motors (GEM-40) solid rocket motors and a hypergolic second stage that burns nitrogen tetroxide and a hydrazine blend called Aerozine 50 in its restartable Aerojet Rocketdyne AJ10-118K engine.
