Spektr-R, Russia’s Only Space Radio Telescope, Stops Responding to Commands

Russia’s only orbiting space radio telescope, Spektr-R (RadioAstron), has stopped responding to the spacecraft’s control staff, the BBC reported Saturday, however Astro Space Center chief Nikolai Kardashev told the BBC that it is still transmitting scientific data.

Spekt-R has a 33-foot radio antenna dish that works in conjunction with ground-based radio telescopes under a universal program. According to the BBC, Roscosmos staff said that the craft—launched in July 2011 on a Zenit-3F expendable carrier rocket—has operated well beyond an original five-year projected lifespan. It stopped responding on Friday, despite repeated attempts to re-establish a connection. Spektr-R head of research Yuri Kovalev told the BBC “there is still hope” that Roscosmos staff will be able to restore functionality

“Specialists of the Main Operational Group of Spacecraft Control are carrying out work to remove the existing problems… Beginning with January 10, 2019, problems emerged in the operation of the service systems that currently make it impossible to tackle a targeted task,” Roscosmos wrote in a statement to TASS, Russia’s state-run news agency

Extra details on the idea of the malfunction were not immediately available.

Russia Beyond, another Russian state media source, reported in 2016 that Spektr-R was required to continue operating untilat least late 2018, with research including galactic nuclei and magnetic fields, quasars and pulsars, and other space projects:

The new program is focused on studies of inner regions of dynamic galaxy nuclei and magnetic fields, checking of the brightest quasars, research of water-vapor clouds in space, pulsars and interstellar issue, gravitational experimentation, and so on.

The RadioAstron project depends on a ten-meter orbital radio-telescope, the one of a unique astrophysical observatory Spektr-R which forms an incorporated radio interferometer with a super-substantial base together with ground-based radio-telescopes. The observatory is entrusted with directing basic astrophysical studies in electromagnetic spectrum bands. RadioAstron has a record discrimination based on distances of up to 350,000 kilometers between telescopes.

While it was first launched in 2011, Space News reported at the time that the craft was originally slated for a launch in 2004 or 2005 “before encountering multiple delays in its construction.”

Another more up to date radio telescope, the Canadian Hydrogen Intensity Mapping Experiment (CHIME), is still not yet completely operational but rather made the news this week when it detected 13 new quick radio bursts, mysterious high-energy pulses from unknown, inaccessible sources that have traversed billions of years across the galaxy. Potential clarifications for quick radio bursts include magnetars (rapidly spinning neutron stars), neutron star-white dwarf mergers, collapsed stars, black holes, and—especially in last place evidence—some kind of artificial, extraterrestrial source. Among CHIME’s discoveries was the second-since reported repeating quick radio burst, however mission staff told Science Magazine this week that they hope to eventually discover hundreds or even thousands of fast radio bursts.
