Right now, miles above your head, there are fleets of robotic, weaponized satellites poised to do battle as the world’s superpowers await the opening salvo in a very real cosmic chess match.

When it comes to Russia, the real cause for concern surrounds a mysterious object known cryptically as 2014-28E. The object first appeared in space soon after the launch of three Russian military communication satellites. Initially, many believed 2014-28E was just another piece of debris left over from the launch. Not long afterward, however, this hunk of space junk began to swiftly change orbit, demonstrating an onboard propulsion system. What exactly 2014-28E is is still unknown, as the Russians have remained tight-lipped on the matter. Many experts fear that these actions signal that the Russians have revived their allegedly-defunct operation known as Istrebitel Sputnik (meaning “Satellite Fighter”), a covert Soviet-era ASAT program.

Russian and Chinese officials have continuously accused the United States of spying on the Chinese Space Station with a top-secret space toy known officially as X-37B. This craft is essentially an unmanned version of the Space Shuttle with a payload bay that’s roughly the size of a pickup truck bed. However, what exactly will be carried and what has been carried on its previous three missions is classified. So too is the entire X-37B budget. Many aeronautic experts dispute claims that the U.S. is using this craft to spy on the Chinese Space Station — but, the complete lack of transparency from U.S. officials hasn’t helped thaw frigid relations between the involved parties.

And the X-37B definitely isn’t the only trick the U.S. has up its proverbial sleeve. Some of America’s most sophisticated ASAT technology is in development as we speak. DARPA, the research and development wing of the U.S. Department of Defense, is now quickly moving along with its Phoenix initiative. The program is based around the concept of a series of robotic craft with the ability to repair damaged satellites from the scraps parts of other defunct satellites already in orbit. Again, from a foreign military perspective, if a satellite has the ability to build something, that satellite also has the intrinsic ability to dismantle something — say, an enemy satellite.
