The Russian manufacturer of Angola’s first communications satellite announced Friday that it has reestablished contact with the spacecraft after engineers stopped receiving signals shortly after its launch earlier this week.

A Ukrainian-built Zenit booster and a Russian-made Fregat upper stage launched with an Angolan communications satellite Tuesday from the Baikonur Cosmodrome in Kazakhstan, but engineers lost contact with the spacecraft soon after its deployment in orbit more than 22,000 miles above Earth.
