According to the Houston Chronicle, spacewalking astronauts uncovered new signs of damage within a crucial rotational mechanism of the solar power system aboard the international space station early today.
Dan Tani and Peggy Whitson made the discovery after they re-routed external cooling system lines to prepare the orbital outpost for the arrival of the European Columbus science laboratory module in December.
The troubled rotational mechanism is one of two circular joints on opposite sides of the station that enable outstretched solar panels to track the sun as the outpost circles the Earth. Constant tracking permits the most efficient generation of electrical power for the station's life support systems and scientific research.
