At the Spartan console, we have 12 rotating joints: 2 TRRJs in blue (Thermal Radiator Rotary Joint- which move the external cooling radiators to get the best heat rejection angle), 2 SARJs in pink (Solar Alpha Rotary Joint- which move 4 solar arrays each in one dimension) and 8 BGAs in yellow (Beta Gimbal Assembly- which each move a single solar array along a different axis from the SARJ). Between the SARJ and BGA we can point the solar arrays pretty dead on at the sun to maximize power generations.

Starting at 10am today (Wednesday), I'll be in mission control, helping to prepare the ISS for ATV 3 docking. You can also watch the docking live on NASA-TV starting at 3:45 CDT or at http://www.nasa.gov/multimedia/nasatv/schedule.html.
