Describe the Spitzer Telescope


About The Spitzer telescope is a reflector of lightweight Witchery-Chretien. Weighs less than 50 kg and is designed to operate at an extremely low temperature. The telescope has a hole of 85 cm in diameter. All parties except the support of the mirror are made of lightweight beryllium. Beryllium is a very strong material that works well in the construction of space telescopes infrared, because has a specific heat low to very low temperatures. The telescope is attached to the upper shell of the Crystal cooled by steam, which maintains the science instruments too cold.
