Satel­lite’s ice mis­sion

Wales On Sunday - - NEWS -

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.
