HOUSTON - The space shuttle Discovery crew was awakened by the Beach Boys hit "Good Vibrations" on Monday to get them ready for a day of work trying to shake loose a jammed solar energy array. Two spacewalking astronauts were scheduled to work on the stuck solar wing, with instructions from their counterparts inside the international space station and in Mission Control. It was to be the fourth spacewalk of this now 13-day mission. NASA added it to the schedule on Saturday after several attempts to fully fold the solar array were unsuccessful. U.S. astronaut Robert Curbeam was poised to...

CAPE CANAVERAL, Fla. - NASA began retracting via remote control a 115-foot solar panel on the international space station Wednesday, likening the tricky task to folding a road map back up and stuffing it in the glove compartment.

The folding-up began shortly before 1:30 p.m. EST and was expected to take about five hours. A crease developed when the array...

Phone messages left by The Associated Press seeking comment from his attorney and...

But these high energy photons penetrate and interact in normal materials and cannot be focused by lenses and mirrors like those in optical telescopes. So how do you make an image in gamma-ray light? One way is to use a patterned mask of material which can...
