Astronauts successfully unfurled the newly installed solar wings at the international space station Friday, a nerve-racking procedure that went exceedingly well and brought the orbiting outpost to full power.
To NASA's relief, both wings went out smoothly, one at a time. Nothing hung up, and none of the panels stuck together like they had on previous panels.
The wings stretched more than 240 feet, a glistening golden hue in the sunlight and a dazzling sight for the astronauts and everyone else involved.
"It's just really amazing," said Mike Fincke, the space station's skipper. He said there was "a shout of triumph" aboard the linked station-shuttle complex once the two wings were fully extended.
At Mission Control, flight controllers burst into applause. Some engineers were in tears.
"It was just really like a great weight had lifted," said flight director Kwatsi Alibaruho.
The work was a highlight of shuttle Discovery's mission. Completed 220 miles above Earth, the new panels are the final pair of electricity-generating wings and should boost the amount of science research at the orbiting outpost.
