UPDATE: TASS reports that controllers have re-established contact with the spacecraft and are receiving telemetry. The report offers no further details at this time.
Russian officials say they have lost contact with the Angosat-1 communications satellite, which was launched from the Baikonur Cosmodrome on Tuesday aboard a Zenit 2SB booster.
“Contact has temporarily been lost,” the source told AFP, adding specialists were now looking into the matter.
The source said officials had stopped receiving “telemetry data” but called it a “rather common situation” and expressed the hope that contact would be re-established.
The reason for the loss of contact was not immediately clear.
The Russian space agency Roscosmos said the Zenit booster performed as planned, deploying Angola’s first communications satellite into its intended orbit. Contact was lost after the spacecraft separated from the booster’s upper stage.
The spacecraft is a joint $280 million project between Angola and Russia that was funded with credit from Russian banks. The spacecraft was built by Russia’s RSC Energia. Fifty Angolans were trained to operate and maintain Angosat-1 from a control center outside Luanda.
