Shuttle above the ET , relative to the ground
It's only since recently that the Shuttle rotates and presents its back to space (or rather the TDRS) before it gets to orbit.
One consequence is if the Shuttle flies over here just after sunset, it's harder to spot than had the white wings been presented to observers, like before.
It narrowed our chances to see it 19 minutes after liftoff....
When Orion will fly to the station, it will be even harder (much smaller).
