Space shuttle tank, ET-94, arrives in Marina del Rey

MARINA DEL REY, CA -- NASA's last remaining space shuttle external tank, known as ET-94, arrived at Fisherman's Village in Marina del Rey Wednesday morning.

On Saturday, it will begin a several-hour long journey weaving through city streets en route to the California Science Center in Exposition Park.

When it reaches its destination, it will join the space shuttle Endeavor, which made a similar journey in 2012.

ET-94 started its 5,000 mile journey from New Orleans in April, making its way through the Panama Canal.

Since the tank isn't as wide or as high as Endeavor, trees won't need to be cut down and fewer utilities will be impacted.

"We used a system called a 3D scan of the route and that gave us the exact height of all the cables and then we had to go by and figure out who owned those cables," Nate Miranda with the California Science Center said.

The tank will become the second of three components needed to build a full stack replica for Endeavor's final display, upright, in the launch position.
