NASA launches satellite ICESat-2 to measure Earth's sea ice, glaciers and oceans.
NASA's most advanced space satellite designed to precisely measure changes in Earth's ice sheets, glaciers, sea ice and vegetation around the world was launched from Vandenberg Air Force base in California on September 15, 2018.
The USD 1 billion, half-ton ICESat-2 launched aboard a United Launch Alliance (ULA) Delta II rocket from Vandenberg Air Force base at 6:02 am (local time).
The mission will provide insight into Earth's frozen regions -- the Cryosphere -- which is rapidly changing with our warming climate.
Melting glaciers and polar land ice contribute to rising sea levels.
Shrinking sea ice changes Earth's energy budget and can modify ocean circulation patterns that buffer climate extremes.
With ICESat-2's frequent and precise measurements of elevation, scientists will be able to see where ice is flowing, melting or growing and can investigate the global impacts of these changes.
In forested areas, height information will help researchers calculate how much carbon is stored in trees.
