A SpaceX capsule carrying four astronauts has launched on its way to the International Space Station, beginning a journey that will bring the orbiting laboratory back to full staff after a month of operating with a skeleton crew.

Axar.az informs, citing CNN, the mission, called Crew-12, lifted off at around 5:17 a.m. ET Friday from Cape Canaveral Space Force Station in Florida. The spacecraft is expected to dock with the ISS Saturday afternoon.

NASA, which contracts SpaceX for the astronauts’ transport to and from the space station, had sought to expedite the Crew-12 launch due to the staffing situation. But the agency had to forgo two possible launch windows on Wednesday and Thursday because of unfavorable weather along the rocket’s flight path.
