American scientists from the Harvard-Smithsonian Center for Astrophysics reported the discovery of the experimental satellite S73-7, which disappeared without a trace in the 1990s. This was reported by oppression Gizmondo.
S73-7, also known as the infrared calibration balloon, was launched in 1974. The object was intended to calibrate the remote sensing system. However, the 66-centimeter-wide device could not return to its operating position after entering orbit at an altitude of 800 kilometers above the Earth.
For a while, terrestrial systems were able to track the now-useless space probe, but it disappeared from radar about 25 years ago and was only found at the end of April 2024.
Although S73-7 had no value, its discovery was a significant breakthrough for scientists involved in the search for space debris, as the safety of the spacecraft and humans operating in orbit depended on this information.
According to experts, the S73-7 probe has been added to the catalog of more than 20 thousand orbital objects, most of which consist of spent rocket stages and failed satellites.
Previously Japan appeared A satellite into orbit to combat space debris.
