Russia on Thursday sent into space a Proton rocket carrying a US telecom satellite, Echostar-21, the first launch in a year after an engine glitch sparked a probe into manufacturing flaws.

“The Proton-M was successfully launched at 6:45 am (0345 GMT/ 9:15am IST),” from the Baikonur cosmodrome in southern Kazakhstan, the Russian space agency Roscosmos said.

Russian Rocket Returns to Service With Launch of US Satellite“All the phases went off as scheduled,” a statement said.

The Proton-M is the largest Russian carrier rocket and has been used since 1965. But it grounded Proton launches in June last year after a series of embarrassing setbacks.

Echostar-21 will provide telecommunications services in Europe and is set to be put into orbit at 1258 GMT, Roscosmos said.
