The shuttle reached the launch pad after midnight following a 10 1/2-hour trip, crawling at a pace no faster than 1 mile an hour in a 4.2-mile journey from an assembly building. The start of the move was briefly delayed by the discovery of a crack in the external fuel tank's foam insulation. NASA later said the crack was no reason for concern. The flaw was discovered as the spacecraft was being readied for the first shuttle launch since Columbia fell to pieces ÔÇö a disaster blamed on a chunk of foam that fell off the tank during liftoff and gashed one of the wings. NASA spokeswoman Jessica Rye described the flaw as a hairline crack and said after sending images of it to the tank's manufacturer in Louisiana, the space agency concluded it did not need to make any repairs. NASA later said the 1 1/2-inch crack was high up on the shuttle in a spot where if foam flew off it would not likely hit the vehicle. "It's a very, very tiny crack. Very, very narrow ... well within our experience base," said Mike Leinbach, shuttle launch director. "It was an acceptable condition for flight, so we rolled on out and we're going to fly with it just as it is." After a delay of at least two hours, NASA then began moving Discovery from its assembly building to the launch pad. Because of Columbia's disintegration over Texas in 2003 ÔÇö and the deaths of all seven astronauts aboard ÔÇö the tank has been extensively redesigned for Discovery's flight. NASA plans a mid-May liftoff with a launch window from mid-May to June ÔÇö a period dictated by the position of the international space station, the shuttle's destination. Discovery was moved on a 5.5 million-pound transporter, a huge platform on caterpillar tracks, along a specially built road that is almost as wide as an eight-lane highway. The transporter was graced with a banner signed by NASA employees that read, "We're Behind You Discovery." The move went smoothly until gauges gave off false indications about whether the vehicle was level as it climbed a ramp leading to the launch pad. The transporter was backed up to level ground so workers could test the gauges and replace a loose data card that appeared to be the problem. The vehicle resumed moving after about a 2 1/2-hour delay. "It's a great sight to see Discovery rolling out to the launch pad," shuttle commander Eileen Collins, who will lead the crew on the next mission, said from Mission Control in Houston. "We know we are getting close." Shuttle program manager Bill Parsons said he had goosebumps on his arms as he watched the shuttle make its way to the launch pad. "Today was absolutely special," he said. Link to comment Share on other sites More sharing options...
Charles Lindsey Posted April 13, 2005 Report Share Posted April 13, 2005 Hmmmm, Seems I remember being at a friends house and some cable channel was on. The show features massive machines such as huge cranes, huge earthmovers, and a paver capable of paving an eight lane highway at once. The one I saw had a segment on the actual "mover". It was pretty neat. Too bad I don't remember any details. Edit: Bingo! http://science.ksc.nasa.gov/facilities/crawler.html Link to comment Share on other sites More sharing options...
jamotto Posted April 13, 2005 Author Report Share Posted April 13, 2005 The Transporter is huge, I took a picture of it just dwarfing a pickup truck sitting next to it. Link to comment Share on other sites More sharing options...
DeepFreeze Posted April 17, 2005 Report Share Posted April 17, 2005 Sometimes I find it impossible to believe that something that huge not only exists, but moves. That's why I'm going to be an engineer Link to comment Share on other sites More sharing options...
