Russia may be testing a satellite capable of chasing down other orbiting spacecraft, observers say.
Such technology could be used for a wide variety of uses, including to repair malfunctioning spacecraft, but also to destroy or disable them.
The Kosmos 2499 satellite separated from the upper stage of its rocket two years ago and then chased it down.
