The Vehicle Assembly Building (VAB) at NASA's Kennedy Space Center (KSC) is a building designed to assemble large space vehicles, such as the massive Saturn V and the Space Shuttle. The future Space Launch System (SLS) will also be assembled there.

The Kennedy Space Center sits on a 220 square mile National Wildlife Refuge. With over 500 different species, and more than 15 endangered species, NASA is proving that technological innovation can exist harmoniously with nature.

Rick Husband (July 12, 1957 – February 1, 2003) was a U.S. Air Force Colonel, pilot, and astronaut who was Commander of Space Shuttle Columbia mission STS-107. He and the rest of the crew of STS-107 were killed when Columbia disintegrated during reentry into the Earth's atmosphere. Husband is a recipient of the Congressional Space Medal of Honor, and the namesake honoree of the Cygnus OA-6 spacecraft. Photo credit: NASA

Before entering the PHSF Clean Room, individuals have to put on "bunny suits" and go through sterilization to avoid contamination of the spacecraft.

You can see the engines sticking out of the bottom, underneath the launchpad.

Human spaceflight is returning to American soil!

This place is haunting at night
