Russian cosmonaut Musa Manarov was fiming a space capsule dock the MIR (the Russian space station) when he noticed an object that looked like it was coming off the spacecraft. However, Manarov knew there could be absolutely nothing loose at that point, and as he watched the object it floated downwards and away from the capsule. He still doesn’t have an explanation for what it was, but he definitely knows it wasn’t space junk, despite what others have said. Watch the footage here.
