Explanation:
First flown in 1992, Endeavour, the youngest space shuttle orbiter,
is being prepared for its 25th and final trip to
low Earth orbit.
Seen here from
an exciting
perspective 400 feet above the floor of
Kennedy Space Center's Vehicle Assembly Building,
Endeavour (OV-105) is mated
to an external tank and solid rocket boosters just prior to
roll out to launch pad
39A on March 11.
The completed
space
shuttle stands over 18 stories tall.
Intended for an April 19 near sunset launch
on STS-134,
Endeavour will head for the International Space Station and deliver
the AMS cosmic ray experiment.
The final flight of Endeavour will be the penultimate planned
space shuttle flight.
