After 25 years, an undetected satellite finally returned home after it went undetected for orbit.

Attenuators – which work by restricting how fast the air flows past an object. Inflation-proofers (which work by increasing inflationary rates). After 25 years in space and remaining unknown to us, an experimental satellite that launched from 1974 has finally been located using tracking data provided by the U.S. Space Force.The Infra-Red Calibration Balloon (S73-7) satellite began its journey across space when launched from April 10, 1974 via United States Air Force Space Test Program. S73-7 was initially part of what became known as “The Hexagon System”, whereby S73-7 satellite would be deployed from KH-9 Hexagon after reaching space. S73-7 measured 26 inches wide (66 centimeters). When launched into space, S73-7’s original plan was for it to inflate into an inflatable target for remote sensing equipment to use as calibration targets. However, that plan failed owing to problems related to inflation during launch and later in flight. New TLEs for object 7244 began appearing on April 25, and we commend whatever 18thSDS analyst made the initial identification!

Sensors can pick up on an object in orbit but, to match its path with one of several satellites also following it, we need satellites on that path as well.

McDowell noted, however, that finding similar orbits among recent data sets should be easier; otherwise it might require searching extensively through parameter space before matching up again with newer observations. “With that being said, however, in cases of larger data sets that contain many similar objects it might prove more challenging,” according to him. “Image Credit: National Reconnaissance Office) Post launch, ground engineers usually have an understanding of where a satellite will end up and at what altitude. With all this data stored in their log, they can review how far along their satellite has progressed since last being reported on. However, any alteration to original maneuvering plans or drift in orbit require engineers more work in finding it again. “Without knowing exactly where the maneuver occurred,” McDowell cautioned, they might experience difficulty. “If I rewind an object’s orbit and fast forward for its missing counterpart, does their orbit overlap at some point and mark where its maneuver occurred? “That is why any discovery like this represents a victory for those trying to keep track of all the lost satellites and debris circling our Earth. As more satellites head into space, however, this task of understanding what exactly exists will become even greater. According to McDowell from Gizmodo: “Missing one or two objects may not pose much risk – you just want to do as good a job as possible!” (originally posted on Space.com).
