NASA launching space laser to track Earth’s polar ice loss

This article discusses how NASA researchers are using space lasers to track Earth’s changing climate with greater precision than ever before.

Next month, the space agency will launch the Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2) about 300 miles above Earth, where it will use six lasers to measure the changing heights of Earth’s polar ice over the course of its three-year mission.

The $1.1 billion mission “will advance our knowledge of how the ice sheets of Greenland and Antarctica contribute to sea level rise,” said Michael Freilich, director of the Earth Science Division in NASA’s Science Mission Directorate, in a statement.
