I have not written anything on the military subject for a long time. So I'll start right away with the new info. In the Zhukovsky (Moscow suburb), the MiG-31 was seen with, presumably, an anti-satellite missile or its mock-up. Although this is only a plausible version. There are also assumptions that this is a modification of the "Kinzhal" ("Dagger") missile with a radar homing. Also there is an assumption that this is a deliberate leaks of information.
