Backdropped by the blackness of space, this nadir view of S1 truss and its center Heat Rejection System HRS Radiator was photographed during the flyaround by the Space Shuttle Discovery following the undocking of the two spacecraft. Discovery pulled away from the complex at 2:24 a.m. CDT on August 6, 2005. Also visible is part of the S0 truss and the Node 1/Unity and Destiny laboratory module.
