Spektr-M
scientific satellite
Spektr-M (Russian: Спектр-M) is a proposed Russian scientific satellite with a 10 m (33 ft) sub-millimeter to far-infrared 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. Spacecraft design documentation and prototyping is currently underway. Due to repeated budget cuts since 2019, the launch is not expected until 2035.
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.
This brief starts where responsible research should: with the source description of “Spektr-M” as scientific satellite. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as scientific satellite. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Mar 21, 2026. The linked authority identifier is Q60515646. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2019 and 2035.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
- Current terminology
- Classification context
- Finding cited technical literature
Primary datasets, specimen catalogues, standards bodies and the most recent peer-reviewed literature.
Three-step research path
- Establish the record: confirm the title “Spektr-M”, its source revision and the description used here.
- Expand the search: follow Spektr-M primary sources, Spektr-M archive and Spektr-M research across catalogues and specialist indexes.
- Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.
Questions for further research
- Which source most directly establishes the central claim about “Spektr-M”?
- Has classification or technical consensus changed since the cited source?
- Is the terminology current, historical or disputed?
