Amateur Skygazers Have Already Found the New Spy Satellite

Last week, the U.S. National Reconnaissance Office launched NROL-37, carrying its latest spy satellite into geosynchronous orbit via Delta IV-Heavy rocket. But it only took amateur space enthusiasts a few days to locate the mysterious new craft in the skies near Malaysia, over the Strait of Malacca.

While the contents and capabilities of the NROL-37 mission's payload are classified (the satellite is innocuously labeled US-268), its need to hitch a ride on the world's biggest rocket strongly suggests it is the seventh member of the Mentor/Orion family, an extra-large class of signals intelligence (SIGINT) satellites which help provide eavesdropping capability to US intelligence agencies.



Their large size also makes Mentor satellites the easiest to find and photograph. In a blog post, Dr. Marco Langbroek details how he and two other amateur skygazers found the Mentor-7 satellite near 104 E longitude over the course of a few days using standard photographic equipment. (You can always spot a geosynchronous satellite by taking long exposures of the sky at night and noting which “stars” aren’t moving.) more
