Shuttle and Soyuz orbits: lap each other ? John Doe 09-19-2006

Soyuz launched while Shuttle was already separated from ISS. So 3
vehicles will share the same orbital plane for a couple of days.


Will the Syouz lap the shuttle during this period of co-existance in the
same orbital plane ? if so, how close would they be ?

Are there pre set rules to govern orbits to prevent any chance of
collision ? For instance, when shuttle fires its de-orbit engines, are
there rules to ensure that the Suyuz is on a higher orbit already ?

The Soyuz just passed below the orbiter, at a range of 34 miles.

Did Atlantis's crew manage to take a picture?

I suppose they could but Soyuz would only be a tiny speck at 34 miles range.

34 miles is a big seperation, but how wide is the "tunnel" (boundaries
of the predicted flight path) for "Soyuz" at that point? I assume that
the calculations pre-launch were able to give sufficient confidence
that the paths wouldn't intersect at the wrong time.

(I'm thinking of the 3D analogue of those hurricane prediction maps,
where the red ink is the 90% likelyhood of the hurricane's path, and
the yellow ink is the 80% likelihood, ...)
