Space Station and Discovery shoot over Valley

The International Space Station and the shuttle Discovery, arc accross the sky in this photo from Art Carson in Valemount March 7th.

The bright streak is the space station (it was travelling from right to left) and the very faint, almost invisible streak to the left on almost exactly the same path is Discovery, which was travelling well ahead of the space station having undocked from it several hours ago in preparation for its final landing. Direction of view is to the southwest.
