奮進號太空梭太空人第三度漫步 維修太空站
法新社╱楊一峰 2008-11-23 15:20
(法新社華盛頓22日電)美國奮進號太空梭(space shuttle Endeavour)上的兩名太空人,今天完成7小時太空漫步,維修在軌道上的國際太空站。這是他們預定進行的第三次太空漫步。
這兩名美國太空人是45歲的史蒂芬森派柏(Stefanyshyn-Piper)和44歲的鮑文(Steve Bowen)。他們為連接在國際太空站上的三對天線陣清理並加潤滑油,當時他們穿著厚重的太空衣,在地球上空約220哩(354公里)處。
這次太空漫步是這次從11月15日開始的15天任務中,最長的一次,在格林威治時間0058(台灣時間0858)完成。
史蒂芬森派柏與鮑文共同修護國際太空站右弦太陽能板的第一個旋轉接頭,損壞的零件將帶回地球檢驗。
這項複雜的工作由41歲的金布羅(ShaneKimbrough)指揮,他於20日曾經和史蒂芬森派柏一同進行太空漫步。
這次任務的第四次太空漫步,預訂24日進行,將繼續進行維修工作。
這些太空漫步是一項「改善家園」計劃的一部分,改善家園計劃將增加國際太空站的人員容量,從3人增加到6人。

Endeavour astronauts conduct repairs on third spacewalk
WASHINGTON (AFP) – Two astronauts on the US space shuttle Endeavour have completed a seven-hour spacewalk as part of an effort to repair the orbiting International Space Station.
Americans Heide Stefanyshyn-Piper, 45, and Steve Bowen, 44, cleaned and lubricated the station's three double solar antenna arrays attached to the orbiter's exterior, working in bulky spacesuits almost 220 miles (354 km) above the Earth.
The spacewalk, the longest of the 15-day mission, which began on November 15, was completed at 0058 GMT Sunday.
Stefanyshyn-Piper and Bowen, both US navy captains, worked on repairs of the ISS's starboard Solar Alpha Rotary Joint race ring and replacing trundle bearing assemblies. The worn-out parts will be taken to Earth for inspection.
The complex work was orchestrated by Shane Kimbrough, 41, who was on a spacewalk along with Stefanyshyn-Piper on Thursday.
The mission's fourth spacewalk, continuing the repair work, is scheduled for Monday. During this upcoming mission, the astronauts will focus on the lubrication and servicing of the port solar alpha rotary joint and the replacement of the final trundle bearing assembly.
The spacewalks are part of an ambitious "home improvement" project designed to double the station's crew capacity from three to six.
As the two astronauts worked on the exterior, the rest of the seven-strong crew ferried equipment from the Endeavour module to the ISS. Starting from Wednesday, the team began installing a freezer and an oven for scientific experiments by NASA's Destiny Laboratory Module.
The additions also include two new sleeping quarters, exercise equipment, a second toilet, two new ovens and a refrigerator.
During an earlier spacewalk on Tuesday, Stefanyshyn-Piper let slip her tool bag and watched helplessly as it floated off into the void of space. Mission Control at the Johnson Space Center in Houston however said the work on the ISS's solar antenna rotation system would continue as planned.
Meanwhile, NASA experts continued to work on problems with a 250-million-dollar urine processor unit that is designed to process urine, perspiration and bath water into drinkable water.
NASA said a centrifuge motor inside the distillation unit was running too slow and drawing too much electrical current.
The device is essential for doubling the accommodation capacity, as it would be able to recycle the station's 6.8 tonnes of waste water produced each year.
Once in place, the unit would make it no longer necessary to regularly ferry vast quantities of water to the space station.
