A Russian Satellite Appears to be Stalking an American KH-11 Spysat

Publicly available data suggests that a Russian inspector satellite has shifted its position in orbit to bring it relatively close to a U.S. KH-11 spy satellite. Russia has a number of what it calls "space apparatus inspectors" in orbit, which the U.S. government and others warn the Kremlin could use to gather intelligence on other satellites or function as "killer satellites," using various means to damage, disable, or destroy those targets.
