Proton-M successfully launches Yamal 601 to GEO
Russia’s Proton-M rocket launched the Yamal 601 communications satellite for Gazprom Space Systems Thursday. Proton lifted off from the Baikonur Cosmodrome at 22:42 local time (17:42 UTC), ending with a nine-hour, thirteen-minute mission that sent Yamal to geostationary orbit.

According to industry sources, Yamal-601 was released from the Briz-M upper stage into orbit well within specifications. However, on June 4, Gazprom space systems announced that specialists at Thales Alenia Space had found it necessary to conduct additional checks related to the operation of the apogee engine aboard the satellite, which could require to change the timeline of its transfer to the operational orbit. The company said that the issue had not involved a failure of the engine.

Apparemment, il aurait des vérifications à faire sur le moteur d'apogée du satellite qui conduirait à un retard dans la timeline prévue pour atteindre l'orbite GEO.
On ne sait pas s'il s'agit d'un problème sur le moteur ou non
