EXCERPTS: Six mysterious Russian satellites launched earlier this year have been creeping toward an observation spacecraft used by Ukraine. Experts worry the complex maneuvers may be a prelude to an attempt to destroy the satellite or disrupt its operations.
Something about the way in which Russia placed into orbit a batch of its Kosmos satellites in late April of this year piqued Greg Gillinger’s interest. Gillinger, the Senior Vice President at space intelligence company Integrity ISR, thought it was strange when Russia used its Soyuz rocket to drop off the first of the satellites at an altitude of 550 kilometers, then dispatched the rest to a different orbital plane using the Volga space tug.
The satellites, numbered 2609 to 2614, weigh about 600 kilograms each. But that’s about as much as Western analysts know about them. For Gillinger, the effort Russia put into fine-tuning its orbits raises alarms.
[...] “My assumption is that you don’t do this by accident,” said Gillinger. “It requires an enormous amount of energy to change orbital inclination. It’s not typical to see reconnaissance satellites or communication satellites or other types of satellites do anything like this.”
[...] Gillinger says that although the Russian sextet doesn’t “do anything dangerous or alarming” at the moment. The close approaches suggest that Russia may want to cause some harm to the ICEYE satellites or disrupt their operations.
“It’s a behavior we haven’t seen before,” Gillinger said. “It could be something as easy as an inspection mission. We don’t know. They might even want to interfere with the ICEYE satellite kinetically or non-kinetically.”
[...] Victoria Samson, the Chief Director for Space Security and Stability at the Secure World Foundation, said that although the Kosmos satellites are not the first Russian spacecraft to sneak up on Western spacecraft in orbit, the incident is a step-up from earlier Russian threats.
“This type of RPO (rendezvous and proximity operations) is not unusual for Russia,” Samson told Supercluster in an email. “Their Luch and Luch 2 satellites have gotten co-planar [orbiting in the same plane] with numerous US intelligence satellites. But this is the first time, as far as I know, that Russian satellites have gotten co-planar with a commercial satellite in low Earth orbit.”
[...] “We might want to start thinking about equipping satellites with their own space awareness capabilities,” he said. “If you really want to be certain what’s going on around your satellites, having an onboard capability to see the surrounding area will become more important..."
[...] Space security experts have been sounding the alarm for years about emerging threats in the space environment. Last year, China sent ripples through the space world by performing close-proximity maneuvers described as satellite dogfighting. U.S. military sources said at that time that five Chinese satellites had been moving around each other “in synchronicity and with control” in a way reminiscent of the acrobatic chases performed during the Second World War between German and British fighter aircraft.
In January this year, Germany’s State Secretary for Defence Jens Plötner said that European satellites experience interference from Russia and China “on an almost daily basis,” according to Euronews... (MORE - missing detail)
