USA TODAY International Edition - - FRONT PAGE -

A NASA satel­lite de­signed to pre­cisely mea­sure changes in Earth’s ice sheets, glaciers, sea ice and veg­e­ta­tion was launched into po­lar or­bit from Cal­i­for­nia early Satur­day.

NASA Earth Sci­ence Di­vi­sion di­rec­tor Michael Freilich said 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 alone has raised global sea level by more than 1 mil­lime­ter a year re­cently, ac­cord­ing to NASA.
