Unique Test Chamber Developed for Observatory “Millimetron”
The specialists of “Reshetnev Information Satellite Systems” created a new experimental facility for the space observatory “Millimetron” – vacuum test chamber.
It is designed for thermal vacuum tests of samples of materials that become part of the design of space radio telescope, Roscosmos explained. The available experimental base allows the cooling of elements to the temperature of liquid nitrogen – minus 196 C, that is not enough to simulate conditions as close to space. Thanks to its creation, the designers of the new telescope will be able to expose on Earth the elements of Space Observatory to extreme thermal loads. High availability at very low temperatures is one of the most important requirements for functionality of “Millimetron”.
The new chamber provides the conditions not only of a high vacuum but also a cooling to very low temperatures – minus 268.5 C.
