NASA's Laser Technology Tracks Melting Ice Sheets
Greenland · Published Aug 25, 2026
NASA's satellite laser ranging technology, first demonstrated in 1964, has evolved into a critical tool for monitoring Earth's ice sheets and glaciers.
The technique measures the distance between ground stations and satellites by timing laser pulses, achieving millimetre-level accuracy.

Impact & Risks

The melting of ice sheets in Greenland and Antarctica is contributing to rising sea levels, which pose significant risks to coastal regions worldwide, including India. Rising seas threaten to inundate low-lying areas, disrupt ecosystems, and displace millions of people. The loss of ice also accelerates global warming by reducing the Earth's ability to reflect sunlight. These changes have far-reaching implications for agriculture, freshwater availability, and biodiversity.
