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, heading for an orbital perch more than 22,000 miles above Earth.
A nearly 20-story-tall Zenit rocket lifted off with the Angosat 1 spacecraft at 1900 GMT (2 p.m. EST) Tuesday from Site 45 at the historic spaceport in Kazakhstan, where launch occurred at 1 a.m. Wednesday local time.
A live webcast of the launch provided by Roscosmos showed the Zenit booster climbing through low clouds over the frigid launch base, heading northeast over the Kazakh steppe.
Deployment of the 3,631-pound (1,647-kilogram) Angosat 1 satellite from the Zenit’s Fregat upper stage is expected at 0354 GMT Wednesday (10:54 p.m. EST Tuesday) after three Fregat engine burns to place the spacecraft into a circular geostationary orbit nearly 22,300 miles (nearly 35,800 kilometers) over the equator.
The Zenit rocket, running on an automatic countdown sequencer, was fueled with kerosene and liquid oxygen propellants in the final hours of Tuesday’s countdown at the Site 45 launch pad. The rocket rolled out to its launch pad in Kazakhstan on Sunday aboard a specially-designed rail car.
The Zenit 3F rocket launched Tuesday was powered by a two-stage booster designed by Yuzhnoye and manufactured by Yuzhmash in Dnipro, Ukraine. The Zenit booster was expected to release the Angosat 1 satellite and a Fregat SB upper stage in a preliminary low-altitude parking orbit around eight-and-a-half minutes after liftoff.
