Satellite’s ice mission
A NASA satellite designed to precisely measure changes in Earth’s ice sheets, glaciers, sea ice and vegetation has been launched into polar orbit.
A Delta 2 rocket carrying ICESat-2 lifted off from Vandenberg Air Force Base in California at 6.02am yesterday local time and headed over the Pacific Ocean.
Nasa says the mission will advance knowledge of how the ice sheets of Greenland and Antarctica contribute to sea level rise. The melt from those ice sheets has raised the global sea level by more than 1 millimetre a year recently, according to Nasa.
