Under the question What are Spectr-R's major contributions to radio astronomy that could not have been done from Earth? there is a new comment that points (again) to the BBC News article Spektr-R: Russia's only space telescope 'not responding'.

Is there any newer information? Has reliable communication been re-established? Three months later now, how is Spektr-R doing?

1 Answer 1


On May 30 there had been a meeting concerning the status of Spektr-R. Afterwards Roscosmos published a statement at https://www.roscosmos.ru/26397/

Here a machine translated version using www.DeepL.com (if any Russian speaker is around and would like to provide a real translation, I'll be happy delete this answer):

Spectrum R: Mission accomplished, data processing ongoing

On May 30, 2019, a meeting of the State Commission for the Review of the Flight Tests of the Spectrum-R spacecraft was held. The State Commission, having heard the reports of representatives of the rocket and space industry and scientific community, decided to complete the project "Spectr-R".

At the beginning of January Spectr-R spacecraft stopped contacting the Flight Control Center. Attempts of NGO specialists named after S.A. Lavochkin to ensure communication with the spacecraft as part of the Chief Designer's program were unsuccessful.

The Spektr-R spacecraft (Radioastron) worked for the scientific community 2.5 times longer than planned and exceeded all its main functions as a source of valuable scientific data on our universe. During its work, the Earth's scientific community has received a significant amount of data on the structure of the universe, the processing of which is unfinished and actively continued by scientists of the planet.

At the end of June 2019, the Spektr-RG will be launched, which will create a map of the universe, where all large clusters of galaxies will be marked. With its help, scientists around the world will be able to answer the question - how the evolution of galaxies occurred. Work is also continuing on other scientific instruments of this series, Spectrum-UV and Spectrum-M.

The summary seems to be that attempts to re-establish communication have failed and the mission is officially declared finished.
