TITLE=SHUTTLE WEDNESDAY WRAP (S-ONLY)
INTRO: Two spacewalking U-S astronauts from the shuttle Discovery have completed the latest series of construction jobs on the international space station. V-O-A science correspondent David McAlary reports that before re-entering Discovery, they flew around powered by jet backpacks.
TEXT: Astronauts Jeff Wisoff [WY-sawf] and Mike Lopez-Alegria [Al-uh-GREE-uh] tested the jetpacks to see how well they would prevent a spacewalker from drifting away if he became untethered.
But they ran out of time to practice carrying each other a method of returning a disabled spacewalker.
Earlier Wednesday, they prepared the station to receive solar power panels next month and a U-S laboratory early next year. They tested latches that will fasten those structures and installed a tray that will provide power to the laboratory.
In three previous spacewalks this week, the shuttle crew electronically connected a new docking port and a new cube-shaped aluminum frame to the station after the components were hoisted into place by crane. The frame holds motion-control gyroscopes and antennas, and will be home to the solar panels.
Discovery is to depart the station Friday, less than two weeks before the first long-duration crew arrives for a four-month stay. (SIGNED)
