The article reports on the announcement of the U.S. National Aeronautics and Space Administration (NASA) that astronauts aboard the International Space Station will venture outside on three spacewalks to replace a malfunctioning pump that has shut down part of the station's cooling system.

Unexpected ammonia leaks and a jammed quick-disconnect fitting derailed a marathon eight-hour spacewalk Saturday to replace a coolant system pump aboard the International Space Station, forcing the astronauts to delay the repairs until a second excursion Wednesday. Michael T. Suffredini, manager of the space station program at the Johnson Space Center in Houston, said he was ''disappointed'' the astronauts ran into the unexpected snag, saying a third spacewalk likely will be needed to resolve the leak and bring a replacement pump on line.

There is no crying in space, but Monday was perhaps as close as it gets to a blubberfest in space helmets. As he headed into the airlock of the space shuttleAtlantis after the fifth and final spacewalk to tune up the Hubble Space Telescope, the astronaut and astronomer John M. Grunsfeld paused to pay tribute to the telescope and the human spirit. [ABSTRACT FROM PUBLISHER]

The second spacewalk during a mission of the shuttle Endeavour to the International Space Station proceeded without mishap. The astronauts worked to clean and grease a damaged rotating joint that keeps the station's solar arrays pointed toward the sun. [ABSTRACT FROM PUBLISHER]

China's Shenzhou 7 spacecraft, carrying three astronauts, is ready to be launched after having passed a final check, the state news agency, Xinhua, reported on Tuesday. The launching, from the Jiuquan space center, left, in Gansu Province, a vast barren region in western China, was expected to occur between Thursday and next Tuesday, the news agency reported. This will be China's third manned space mission, and one of the astronauts is expected to perform China's first spacewalk. [ABSTRACT FROM PUBLISHER]

In an audacious spacewalk scheduled for Thursday, two Russian astronauts aboard the International Space Station are to saw away insulation from the Soyuz capsule that is to be used for their ride home later this year, remove a live explosive bolt that is part of the capsule's re-entry apparatus and take it back into the station. The highly unusual procedure is intended to help engineers on the ground understand why the last two Soyuz capsules returned to Earth in a harrowing ''ballistic'' descent that subjected those aboard to higher than normal g-forces.

Astronauts from the shuttle Endeavour completed the assembly of a giant robot called Dextre on Monday in the third of five scheduled spacewalks outside the International Space Station. Dr. Richard M. Linnehan and Maj. Robert L. Behnken of the Air Force removed thermal covers from the Canadian-built maintenance robot's 11-foot arms and attached a 5-foot metal boom to its front for holding equipment and tools. They added a holder for three tools under the 3,400-pound robot's right arm and a pan-and-tilt color camera on its body so operators can observe its work. The $209 million robot, which has passed initial operating tests, will be attached to the station's Destiny laboratory module. [ABSTRACT FROM PUBLISHER]

Building Dextre, the new robotic grappling device for the International Space Station, has meant frustration and elation for astronauts in space and experts on the ground. Shipping the device aboard the Endeavour last week to its new home and getting it together over three spacewalks shows how hard it can be to do things in orbit that may be relatively straightforward on the ground, as when astronauts struggled to remove bulky restraining bolts for the robot's arms with their gloved hands.

NASA managers cleared the shuttle Endeavour for liftoff on March 11 to begin a 16-day mission to the International Space Station. The mission, which involves bringing part of a new Japanese science module to the station and five space walks, will be launched at 2:28 a.m. ''The teams are ready to go launch,'' said William Gerstenmaier, the agency's manager of space operations, at a press conference at the Kennedy Space Center in Florida. Mr. Gerstenmaier said that analysis of the debris from a disabled satellite that the Air Force destroyed last week created a ''trivial'' rise in risk. [ABSTRACT FROM PUBLISHER]
