Abstract
We present an overview of the current status of the space mission Millimetron. Millimetron is a large 10-m cooled space telescope optimized for operation in the submillimeter and far infrared wavelengths. This mission will be able to contribute to the solution of several key problems in astrophysics, such as study of the formation and evolution of stars and planets, galaxies, quasars and many others. The telescope will have an unprecedented sensitivity in the single-dish observation mode and an extremely high spatial resolution as an element of a ground-space very long baseline interferometry (VLBI) system. The mission will have a cryogenic instruments and antenna, which will be cooled passively with radiation shields and actively with mechanical coolers. With this cooling combination the 10-m space telescope may reach a temperature of about 4.5 K. The Millimetron is proposed as a Russian-led mission with an extensive international consortium in various countries. The mission launch is planned for 2017.
