Spektr-M[1] 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, and to look into chemical evolution in the universe, black hole horizon radiation, and dark energy investigation.[2] Spacecraft design documentation and prototyping is currently underway and expected to continue until 2023. Due to budget cuts in 2019, launch is not expected until around 2030.[3]

Overview

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 a halo orbit around the Sun–Earth L2 Lagrangian point.[4]
