SCIENCE BRIEFING
Astronauts unfurled the newly installed solar wings at the International Space Station on Friday, a nerve-racking procedure that 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 stretch more than 240 feet and are the final pair of electricity-generating wings that should boost science research at the station. The work was a highlight of shuttle Discovery’s mission.
