This vacuum chamber in NASA's Glenn Research Center offers one of the closest representations of outer space-like conditions on Earth. NASA and its contractors use the facility to test electric propulsion and power systems designed for use in space.

It comes equipped with cryogenic panels (along the top of this photograph) that can cool the chamber to -440 degrees Fahrenheit, a mere 20 degrees away from absolute zero. According to a news release from NASA, "The extreme cold of this panel freezes any air left in the chamber and quickly freezes the thruster exhaust, allowing the chamber to maintain a high vacuum environment".

The state-of-the-art facility also boasts the highest pumping speed of any electronic propulsion test facility on Earth.
