Virgin Orbit, the sister company of Virgin Galactic, is gearing up for its next space launch in June when it will put six satellites in orbit.

The mission, named “Tubular Bells, Part One” after the first album Virgin Records released in 1973, will launch satellites for the U.S. Department of Defense, Poland’s SatRevolution and the Royal Netherlands Air Force.

A modified Boeing 747–400 jet will carry the LauncherOne rocket to high altitude, then release the 70-foot, 57000-pound rocket into the air.
