00:00:00.000 --> 00:00:07.000


00:00:07.000 --> 00:00:11.000
Space shuttle Endeavour has completed an unusual journey.

00:00:11.000 --> 00:00:13.000
No, it wasn't its upcoming mission into space ?

00:00:13.000 --> 00:00:16.000
in fact, the winged spacecraft hasn't even left the ground at

00:00:16.000 --> 00:00:19.000
NASA's Kennedy Space Center in Florida.

00:00:19.000 --> 00:00:25.000
In preparation for launch on its STS-126 mission, Endeavour moved from

00:00:25.000 --> 00:00:30.000
the spaceport's Launch Pad 39B to nearby pad 39A.

00:00:30.000 --> 00:00:35.000
This is only the third time in more than 25 years that a shuttle has been

00:00:35.000 --> 00:00:38.000
moved from one pad to the other.

00:00:38.000 --> 00:00:43.000
The shuttle began the 8-hour "rollaround" at 8:28 a.m. Eastern time,

00:00:43.000 --> 00:00:48.000
and was in place on Pad A at 4:37 p.m.

00:00:48.000 --> 00:00:52.000
Endeavour and its mobile launcher platform were carried by the giant

00:00:52.000 --> 00:00:56.000
crawler-transporter, which crept along at less than a mile an hour.

00:00:56.000 --> 00:01:00.000
But instead of taking a direct route to its destination, the shuttle had to

00:01:00.000 --> 00:01:02.000
take a bit of a detour.

00:01:02.000 --> 00:01:06.000
The crawler-transporter can only travel on a special road called the crawlerway,

00:01:06.000 --> 00:01:10.000
which is designed to handle the shuttle's enormous weight.

00:01:10.000 --> 00:01:15.000
There is no crawlerway linking the two pads, so Endeavour rolled back to the point

00:01:15.000 --> 00:01:17.000
where the roads to the launch pads meet.

00:01:17.000 --> 00:01:21.000
The shuttle then proceeded toward Launch Pad 39A.

00:01:21.000 --> 00:01:25.000
Now that Endeavour is in place, technicians have installed the payload and will

00:01:25.000 --> 00:01:31.000
continue preparing the shuttle for its STS-126 mission to the International Space Station.

00:01:31.000 --> 00:01:34.000
