Himalayan Glacier Melt Mapped By Analyzing Old Spy Photographs

Katarina Samurović

Declassified Cold War-era spy satellite photographs have shown how much the melting of hundreds of Himalayan glaciers has accelerated in recent decades.

NASA's Advanced Rapid Imaging and Analysis (ARIA) team created this co-seismic Interferometric Synthetic Aperture Radar (InSAR) map, which shows surface displacement caused by the recent major earthquakes in Southern California, including the magnitude 6.4 and the magnitude 7.1 events on July 4 and July 5, 2019, respectively.

Who Coined the Term ‘Remote Sensing’?

Caitlin Dempsey

While the origins of remote sensing can be traced to World War II's use of radar, sonar, and thermal detection technologies, the use of the term 'remote sensing' wasn't coined until the late 1950s.
