The RALPHEE thermal vacuum (TVAC) chamber can test devices and systems up to 1m x 1m in size at temperatures ranging from -180°C using LN2 up to ambient. RALPHEE can achieve vacuum levels below 10-5 torr to simulate the space environment or be operated at partial pressures up to 1 atm to simulate other relevant planetary surface environments.
