Russia's space agency successfully launched a robotic spacecraft Thursday on a journey to the Moon, the country's first lunar explorer since the Soviet Union's Luna 24 sample return mission in 1976.
The Luna 25 mission lifted off from the Vostochny Cosmodrome, located in Russia's Far East, at 7:10 p.m. EDT (23:10 UTC). Heading east, a Soyuz-2.1b rocket propelled Luna 25 through an overcast cloud deck and into the stratosphere, then shed its four first stage boosters about two minutes into the flight. A core stage engine fired a few minutes longer, and the Soyuz rocket jettisoned its payload shroud.
A third stage engine fired next, then gave way to a Fregat upper stage to place Luna 25 into an orbit around Earth. The Fregat engine fired a second time to send the nearly 4,000-pound (1.8-metric ton) lunar probe on a roughly five-day trip toward the Moon. Russia's space agency, Roscosmos, declared the launch a success less than 90 minutes after liftoff, shortly after the Luna 25 spacecraft separated from the Fregat upper stage.
