NASA Plum Brook builds world’s largest vacuum chamber

The world’s largest vacuum chamber has been built by NASA Plum Brook. The vacuum chamber, called the Space Power Facility, resides at NASA Glenn Research Center’s Plum Brook Station in Sandusky OH. It measures 100 feet in diameter and towers at 122 feet tall. Its immense size and ability to simulate the vacuum of space make it ideal for testing the Orion crew exploration vehicle.
