INTERNATIONAL SPACE STATION (AP) -- NASA is calling today's risky
spacewalk a success.
Two American astronauts at the international space station set
out this morning to replace a motor needed to tilt a solar wing
toward the sun.
NASA declared the operation a success after a new motor was
installed and flight controllers tested the motor from the ground.
The spacewalk was a more dangerous one because of the risk of
being shocked. The astronauts, Commander Peggy Whitson and Daniel
Tani (TAH'-nee), virtually did the entire job in the darkness of
night, pausing during daytime swings around the earth to avoid
getting shocked by electricity generated by light.
Now that the solar wing's motor replaced, NASA is trying to
figure out what to do with the wing's clogged joint. It could take
four spacewalks to fix that problem, and future shuttle flights
could be delayed if it's not repaired.
