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.
