I think we are seeing the effects of small changes in the motion of the shuttle, orbital corrections.
1) Notice that all of the lights (except the ones in question) display the same relative motion through the video. They all move slowly toward the top
of the frame. This indicates that they are stars and light sources on Earth, the movement being an indication of the general movement of the shuttle
in its orbit.
2) The first, bright object moves across the frame from right to left. Now, it could be moving to the left relative to the shuttle, or the shuttle
could be moving to the right relative to it. There is no way to tell the difference.
3) As the apparent movement of this object slows, it could be slowing, or the movement of the shuttle relative to it could be changing. If that's the
case, why then does the apparent motion of the other lights not change? If the mystery object is very much closer to the shuttle than the lights,
parallax would cause a small change in the velocity of the shuttle to be much more visible on the near object than on the very distant sources of
4) Note that shortly after the apparent motion of the "important" object begins to reverse, another very dim object becomes visible, moving from
left to right as well.
Summary: an object (ice, junk, etc.) is nearby the shuttle, with a relative motion to the left. The shuttle accelerates gently to the left, causing
the relative motion to slow and eventually reverse. The dim object is on a slightly different trajectory and is closer to the camera, causing it to
appear to be moving faster. The change in velocity is not visible in the other lights because of their distance.
