How many astronauts does it take to unscrew a bolt? "Apparently, it takes three. Two outside and one inside," said Pam Melroy of mission control at Johnson Space Center in Houston. Melroy's jest was at the expense of astronauts from the space shuttle Atlantis, who were trying without much success Wednesday to continue installing power-generating solar arrays -- delivered by Atlantis -- on the International Space Station during a spacewalk.

A cable car system that stalled and left dozens of people stranded above the East River for about 11 hours in April has reopened with upgrades including new motors, emergency provisions and even toilets. Experts have "gone over this thing with a fine-toothed comb," said Herb Berman, president of the Roosevelt Island Operating Corp. The tramway shuttles commuters and tourists between Manhattan and Roosevelt Island.

BP is aiming to restart oil production in the eastern half of Alaska's Prudhoe Bay oil field by the end of September, sources familiar with the company's plans said Thursday. Plans call for a partial restart of a pipeline that connects with the Trans-Alaska Pipeline's Flow Station 1, allowing up to half of the 200,000 barrels a day of lost production to begin flowing again. Prudhoe Bay normally supplies about 400,000 barrels daily, or 8% of U.S.

Technicians at Cape Canaveral successfully swapped out two bolts securing a communications antenna on space shuttle Atlantis because engineers thought they were too short. The last-minute change-out wasn't expected to affect the schedule for Atlantis' planned launch next Sunday on a mission to resume construction on the International Space Station.

In a sudden blow to the nation's oil supply, half the production on Alaska's North Slope was being shut down Sunday after the Alaska exploration group of BP Global discovered severe corrosion in a Prudhoe Bay oil transit line. BP officials said they didn't know how long the Prudhoe Bay field would be off-line. The field's shutdown, a process expected to take days, will reduce oil production by 400,000 barrels a day, BP officials said. That's close to 8% of U.S.

Two astronauts from the shuttle Discovery completed a nearly seven-hour-long spacewalk Monday, installing new equipment and completing crucial maintenance work to the International Space Station that clears the way for NASA to resume construction of the station late this summer.

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.
