Astronauts are back outside
the international space station this morning to install a must-have
solar power array to prevent delays in the addition of a
much-anticipated European research lab.
The job has been made more important due to malfunctioning
equipment on another solar array that helps turn the panels toward
to sun. The astronauts will try to find out what's grinding inside
a rotary joint and causing steel chips to clog the system.
Astronaut Scott Parazynski (pehr-uh-ZIN'-skee) will inspect a
good rotary joint that turns the space station's left set of solar
wings toward the sun and the two will be compared.
Installing the additional solar array and extending those solar
panels to their full 240 feet will help prevent any power
shortfalls that would delay the scheduled arrival of both European
and Japanese laboratories.
