UFO followed the astronauts of the ISS

14 Jan 2017 during release of the ISS astronauts into space for their work, observed several UFOs and this is not space junk. Objects maneuver, perform turns, stop and changing speed.

I wonder what the astronaut saw these UFOs and tried to hide their presence, closing them from the camera with his hand. But despite his efforts, the UFO ended up in the camera lens. For example, one UFO flies to the right, diagonally, and zataskivaya with the housing module of the ISS, comes back, turns at a right angle and flies up.

Then there are three more UFOs. One appears at the bottom of the frame, the second top and the third is flying from left to right.
