Well, "we don't know"... It's mainly: - An anti-satellite weapon not unlike the rockets the Chinese launch at satellites, but more refined and capable of retrieving technology before disabling the craft. - A testing platform for space technology like sensors. It can serve as a makeshift scrappy satellite if you need to quickly deploy a sensor for something. Like you don't know what it's doing but you know what mostly everything else on space that was not launched on board of that thing is doing so there's not much left to imagination here. It's like saying you don't know what Delta Force is doing, yeah you do, they shoot at people. You don't know what people and for what reason but that's not spooky secret alien stuff or anything.
