New Orleans is where the external tanks for the Space Shuttle are built. Above, the NASA Michoud facility shares a long tradition of building space vehicle. These rocket motors are part of the Saturn V rocket boosters that were built at the New Orleans East facility in the 60's and did the heavy lifting for the Apollo space capsules.
Below, the tall building is where the external tanks are stored vertically for some of the final steps of the assembly process.
The Michoud facility will continue on with its space tradition in the next decade with projects to build the Orion crew exploration vehicle, which will carry astronauts to the moon and Mars, and new Ares I Crew Launch Vehicle, the new booster rockets for those.
