6mφ Radiometer Space Chamber is used for verifying and evaluating the optical characteristics, the thermal design, and total performance of spacecraft in a simulated space environment.
The chamber has a "mailbox" shape and is made of stainless steel. This shape improves accessibility. The wall of the vessel is covered with a "shroud" that is cooled to under 100K with liquid nitrogen to simulate the cryogenic background of space.
The optical bench inside the chamber (where test specimen is set) and the external light are loaded on a seismic slab weighing 3700 tons to reduce the transmission of ground microtremors. The foundations of the chamber and rotating machines are separated from the slab so as not to transmit harmful vibration. | | |
