Maneuvering Russian Satellite Has Everyone’s Attention.
A Russian military satellite launched in March has made at least 11 close approaches to the rocket upper stage that released it into orbit, according to a spokesman for the U.S. Air Force. Such maneuvering capability is consistent with, but not necessarily indicative of, an on-orbit anti-satellite weapon. Air Force officials previously said they were closely watching the satellite, and independent space tracking experts and policy analysts have joined the vigil.
The maneuvers started in April, and the most recent occurred in early July, experts said, adding that in at least one case the satellite appears to have nudged the upper stage to a higher orbit. In a response to questions from SpaceNews, Air Force Capt. Nicholas Mercurio, a spokesman for U.S. Strategic Command’s Joint Functional Component Command (JFCC) for Space, said that in addition to its dance with the upper stage, the satellite, known as Kosmos 2504, on one occasion approached an unidentified piece of orbital debris.
It has not approached any active satellites, he said. Kosmos 2504, which launched along with three communications satellites aboard a Rockot vehicle from Russia’s Plesetsk Cosmodrome, is being watched carefully by Strategic Command’s Joint Space Operations Center at Vandenberg Air Force Base, California. Lt. Gen. Jay Raymond, commander of the 14th Air Force and of the JFCC for Space, said in April that the service was “keeping a close eye on” the satellite, whose maneuvers are similar to another Russian satellite launched last year, also along with three communications satellites on a Rockot vehicle. That satellite is known as Kosmos 2499 but is often informally referred to as Object E.
Israel launched theirs in 2003 aboard the Columbia. They then ensured that no one involved could testify.
