    CAPE 1 CANAVERAL — Two American astronauts will venture outside the International Space Station Monday to stow a failed coolant pump and extend the outpost's Canadian railway.

    Wearing protective spacesuits in a deadly vacuum(真空) environment, Stephen Bowen and Al Drew will exit the U.S. Quest airlock at 11:18 a.m.

    The spacewalk(太空漫步) will be the 154th performed since the first two station building blocks were linked in late 1998.

    A late substitute for original lead spacewalker Tim Kopra, Bowen only had a month to train for the dangerous work.

    "Steve brings a wealth of (spacewalking) experience," NASA flight director David Korth said Sunday. "He's a very seasoned shuttle astronaut, and he picked up quickly in (training) runs, coming up to speed on the path that we have."Kopra was injured in a mid-January bicycle accident. Bowen, who flew aboard Atlantis last May, is a veteran of five spacewalks and is the first U.S. astronaut to fly consecutive 2 missions.

    PHOTO GALLERY: Discovery's final mission"He'll be just fine, and we have absolutely every confidence that we'll knock out all these tasks," Korth said.

    Drew will be making his first spacewalk.

    Their tasks include:

    — Rigging up an electrical extension cable between the U.S. Unity 3 module 4 and the Quest airlock.

    The cable routes power to airlock heaters. Adding an extension will make future maintenance work easier once Discovery's prime payload — a permanent stowage unit — is put in place on Unity's Earth-facing port.

    — Moving a refrigerator-sized ammonia pump to an external stowage platform. The pump failed last August.

    — Installing a new section of track for the Canadian rail car system that runs atop the station's 335-foot-long central truss and is used for moving cargo 5.

    — Canting a video camera stanchion to provide clearance 6 from an external stowage platform installed Saturday.

    Still to come: a decision on a proposal to do a fly-around to document the first and only time a U.S. shuttle, a Russian Soyuz space taxi and cargo carriers from Russian, Japan and Europe all are docked at the complex.

    Landing at Kennedy Space Center is set for March 7.(本文由在线英语听力室整理编辑)
