Sir Richard Branson’s Virgin Galactic rocket plane is back in action after a gap of almost two years.

The Unity vehicle, with two pilots and four passengers aboard, climbed high over the New Mexico desert to the edge of space – before gliding back down.

It was billed as the plane’s final test outing before entering commercial service in June.

Galactic has sold over 800 tickets to individuals who want to ride more than 80km (260,000ft) above Earth.

The company expects to start working through this passenger list with Unity flights initially occurring at the rate of one a month. New rocket planes are being designed for service in 2026 that should each be capable of increasing the cadence to one a week.

Unity is a sub-orbital vehicle. This means it can’t achieve the velocity and altitude necessary to keep it up in space to circle the globe.

The spaceship is designed to give its passengers stunning views at the top of its climb, and allow them a few minutes to experience weightlessness.
