| Abstract: | Millimetron is a Russian-led 12 m diameter submillimeter and far-infrared space observatory which is included in the Space
Plan of the Russian Federation for launch around 2017. With its large collecting area and state-of-the-art receivers, it will
enable unique science and allow at least one order of magnitude improvement with respect to the Herschel Space Observatory.
Millimetron will be operated in two basic observing modes: as a single-dish observatory, and as an element of a ground-space
very long baseline interferometry (VLBI) system. As single-dish, angular resolutions on the order of 3 to 12 arc sec will
be achieved and spectral resolutions of up to a million employing heterodyne techniques. As VLBI antenna, the chosen elliptical
orbit will provide extremely large VLBI baselines (beyond 300,000 km) resulting in micro-arc second angular resolution. |
