Discovery gets new fuel tank

2005-01-06 19:17

Cape Canaveral - A redesigned fuel tank for Nasa's first post-Columbia launch emerged from a darkened barge into the morning sunlight on Thursday, inspiring dozens of space shuttle workers who gathered to watch.

"We're no longer recovering from the accident. We're really heading toward a launch. Big change in momentum and morale," launch director Mike Leinbach said.

The arrival of the external fuel tank from a manufacturing plant in Louisiana moved the space programme closer to its goal of a late spring lift-off for Discovery. It was a suitcase-size piece of insulating foam from Columbia's fuel tank that triggered that shuttle's explosion as it re-entered the atmosphere over Texas nearly two years ago.

Some workers photographed the 47m orange-yellow tank as it was hauled atop a wheeled flatbed into the Vehicle Assembly Building, and others walked alongside, pointing out new features.

Clearly missing were the pair of foam ramps that caused the deadly shedding during Columbia's final flight. In their place were eight new heaters, designed to prevent ice buildup when super-cold fuel is loaded right before launch.

Shuttle programme manager Bill Parsons called the tank the safest ever built, "no doubt about it."

Parsons, who was celebrating his 48th birthday, called the tank's arrival the perfect gift.

Back to business

"It's back to business," said Parsons. "It's getting where we are really feeling like we're going to pull this off, and I think that this is just an indication, one of those big symbols that comes in and says, 'You're there. You're getting there.' "

Within half an hour, the tank was inside the assembly building, where it will undergo a month of final prepping.

The tank will be attached to the two solid rocket boosters in February, and all that will be mounted to Discovery in March. Nasa is shooting for a lift-off as early as May.

There was good news in orbit, too, on Thursday: The two men aboard the international space station got their primary oxygen generator working after a five-day breakdown.

Discovery will carry much-needed spare parts and supplies to the space station. It will be essentially a test flight, not only for the redesigned shuttle tank but also for the inspection and repair methods for astronauts in orbit.

Nasa's three remaining space shuttles have been grounded ever since Columbia ruptured on February 1 2003, killing all seven astronauts aboard.
