Iulie - Septembrie 2006 CURIERUL ROMÂNESC 5 __________________________________________________________________________________________________________ But in order to do that, the Discovery astronauts and space station crew must first retract one wing of the older solar arrays providing interim electricity to the U.S. segment of the space station. If that goes well commands will be sent to begin slowly rotating the new set of solar arrays installed in September. The space station has relied primarily on a pair of solar arrays attached to its mast-like Port 6 (P6) truss, but the arrangement was always meant to be temporary since that segment must be moved in the future. STS-116 spacewalkers will shift the space station power systems from the P6 arrays to the solar panels on the space station’s recently installed Port 3/Port 4 (P3/P4) truss segments delivered in September. As part of the STS-116 rewiring process, one of the P6 solar arrays must be folded away to allow the newer solar panels to rotate and track the Sun. (3 Feb. 2005) - Astronauts Nicholas J.M.
