Hello 1550UT The orbital tracking web page shows the Shuttle orientation to be Roll 0.3 Pitch 179.5 Yaw 0.5 What is the reference frame? For the pitch I assume it is the orbital track and they are flying "backwards" But what about roll and yaw, is it the earth's center, and if they are flying the usual routine with the top of the shuttle facing Earth you would think roll would be 180.
