Glenn Extreme Environments Rig (GEER)

GEER is a world-class facility designed to simulate extreme environments

The surface of Venus – here on Earth

The Glenn Extreme Environment Rig (GEER) is a high-tech pressure vessel capable of simulating the temperature, pressure and atmospheric gas mix of many extreme environments in the Solar System and beyond.

These capabilities enable unique science investigations, provide the ability to conduct risk reduction tests on proposed planetary equipment and allow breakthroughs in a multitude of disciplines.

GEER is located at NASA’s Glenn Research Center in Cleveland, Ohio and is currently configured to simulate the atmospheric and surface conditions of Venus.
