Russia's Spektr-R telescope "not responding"

[Eldorado]

Russia's only space radio telescope is no longer responding to commands from Earth, officials say.

Astro Space Centre chief Nikolai Kardashev said some of the Spektr-R satellite's communication systems had stopped working.

But it was still transmitting scientific data, RIA Novosti news agency reports.

The telescope has been operational way beyond its expected five-year lifespan, Russia's space agency Roskosmos says.
