Watch the Space Shuttle's fuel tank get prepped for the last time

There's only one Space Shuttle launch left, which lends significance to nearly every part of the process of getting it ready. Including lifting up the external tank that contains all of the liquid hydrogen and liquid oxygen that powers the three main space shuttle engines during liftoff.

The external tank does the work of getting the shuttle off the ground and propelling towards orbit, and 10 seconds after they cut off, they fall away to break up in the atmosphere and land in the ocean.

The below hypnotizing video shows the gigantic external tank getting lifted up to be prepped for attachment to the shuttle.
