Two spacewalkers bounced around on the end of a "skinny little pole" 210 miles above Earth on Saturday in a daring test for future shuttle repairs. Astronauts Piers J. Sellers and Michael E. Fossum spent 7 1/2 hours outside shuttle Discovery on the fourth day of the ship's visit to the International Space Station.

After analyzing the shuttle's energy consumption, NASA officials on Friday decided to extend Discovery's mission by an extra day and add a third spacewalk to the astronauts' itinerary. Astronauts Piers J. Sellers and Michael E. Fossum will use the extra spacewalk Wednesday to practice making repairs to the carbon material that protects the shuttle's nose cone and the leading edge of the wings from extreme heat, said John Shannon, deputy shuttle program manager.

The launch of the space shuttle Discovery will be delayed from May until at least July to allow engineers time to replace sensors in the craft's hydrogen fuel tank, NASA said Tuesday. A malfunction in the sensors, which monitor hydrogen levels in the tank, could cause the shuttle's rocket engines to shut down prematurely, potentially endangering the mission.

Pacific Gas & Electric Co., California's largest utility, received state regulatory approval Friday to spend $706 million to replace steam generators at its Diablo Canyon nuclear power plant. The plan was approved by a unanimous vote of the California Public Utilities Commission in San Francisco, where Pacific Gas & Electric and its parent, PG&E Corp., are also based.

Concerns that the city's nonstandard fire hydrants could cripple firefighting efforts after a major earthquake have prompted fire officials to reconsider plans to distribute hydrant "adapters" to visiting fire crews. San Francisco is the only city in the state exempt from a law requiring that all hoses and hydrants have 2 1/2 -inch openings. Most of the city's hydrants have a 3-inch opening.

Pacific Gas & Electric Co. announced plans to speed up construction of a $30-million pipeline to replace a line that is vulnerable to flooding in the event of a major levee failure in Northern California. The line would serve the PG&E Corp. unit's largest natural-gas storage facility, near Stockton. The company hopes to have the project completed by winter 2006.

Three crew members were killed and 20 others injured after sewage gushed from a pipe being repaired inside a crowded Royal Caribbean cruise ship docked at the Port of Los Angeles, releasing deadly levels of hydrogen sulfide gas. Crew members aboard the Monarch of the Seas were trying to fix the pipe in a roughly 10- by 12-foot portion of a propeller shaft tunnel on the starboard side of the ship about 9 a.m. when the accident occurred, officials said.

With hugs, handshakes and the traditional tolling of a farewell bell, the shuttle Discovery's astronauts said goodbye Saturday to their comrades on the International Space Station and fired thrusters to send their fragile spacecraft back to Earth. Discovery Commander Eileen Collins thanked the station crew, Russian cosmonaut Sergei Krikalev and American astronaut John Phillips, for "memories that will last forever."

The crew of the space shuttle Discovery resolved one problem Wednesday with protruding "gap fillers" during a first-ever spacewalk under the craft, only to face yet another potential danger in a "poofed-out" insulation blanket under a cockpit window.

Concern over two protruding pieces of heatresistant fabric on the underside of Discovery prompted NASA on Sunday to consider a first-ever in-flight shuttle repair that would require a spacewalk. Paul Hill, flight director for the 114th shuttle mission, said an engineering team of aeroheating specialists expected to have a recommendation today on whether an astronaut would be sent out with a hacksaw to trim off the pieces of fabric, known as "gap fillers."
