Spektr-M  is a proposed Russian scientific satellite with a 10 m (33 ft) sub-millimeter to far infra red space telescope. It is designed to be a successor to the Herschel Space Observatory, covering similar wave bands. It is designed to look into chemical evolution in the universe, black hole horizon radiation, and dark energy investigation.
The purpose of this mission is to study the universe in millimeter to far infra-red wavelengths. The Herschel mission did a similar job with a smaller dish of 3.5 m (11 ft), and this is a follow-up mission. The instruments are to be cooled with liquid helium to 4.5K for part of the mission, but sun shields will allow it to continue in a degraded mode once the coolant evaporates.
It will be placed in the L2 Lagrange point.
