📰 A Russian Satellite Appears To Be Shadowing an American Spy Satellite

"A Russian satellite has positioned itself uncomfortably close to an American spy satellite in orbit around Earth..." reports the Verge, adding that the Russian satellite "has been in constant view of its U.S. target for nearly two weeks now." An anonymous reader quotes The Drive: 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. On Jan. 30, 2020, Michael Thompson, a graduate student at Purdue University focusing on astrodynamics, posted a detailed thread on Twitter... [H]ow Cosmos 2542 is orbiting now means that it now has a "consistent view" of USA 245. "As I'm typing this, that offset distance shifts between 150 and 300km depending on the location in the orbit," according to Thompson.... One possibility is that it could be using onboard systems, such as cameras or other sensors, to gather information about the [U.S. satellite] KH-11, the capabilities of which are highly classified... It may also be possible to gather electronic or signals intelligence data that could be of additional value. Beyond that, the ability of Cosmos 2542 to get into this position at all is notable and is exactly the kind of orbital maneuvering that the U.S. government had pointed to in the past as evidence of potential "killer satellites." A highly maneuverable, but small satellite could possibly get close enough to disrupt the operation of, disable, or destroy another object in space using a variety of means, ranging from electronic warfare jammers to directed energy weapons, such as a laser... Russia is known to be interested in anti-satellite capacities and has developed or is developing a number of terrestrial anti-satellite weapons, including ground-based and air-launched interceptors, too. China is pursuing similar developments, as well. The article points out that is all happening "as the U.S. military is very publicly working to address concerns about the increasing vulnerability of various space-based systems that it relies on heavily... The most obvious expression of this recent push is the creation of U.S. Space Force, an entirely new branch of the U.S. military to focus on American military activities in and related to space, as well as the procurement of satellites and other related systems and infrastructure." And then late Saturday night, Thompson posted another update on Twitter: that the Russian satellite had made yet another manuever on Friday, "and is now drifting back towards USA 245."
