Cryogenic Telescope Assembly Spitzer


The Spitzer (CTA by its contraction in English) consists of four main parts: cryostat superfluity helium, a telescope Ritchey-Chretien lightweight 85cm, a set of outer shells, and housing chamber multiple instruments, which houses the science instruments. Everything is cool, is part of CTA. The CTA is mechanically mounted but thermally isolated from the spacecraft, using beams and supports, as well as protective shields against thermal radiation. The array of solar panels and shields the spacecraft, CTA blocked the sun and the other components of the spacecraft at all times, helping to keep the CTA as cold as possible.
