Virgin Galactic's founder, Sir Richard Branson, has been hoping to make space tourism a reality since 2008. While it has taken a little longer than the 18 months he had originally estimated, the company is getting increasingly closer to accomplishing its mission. On December 13, 2018, Virgin Galactic's suborbital spaceliner, VSS Unity, made history with the longest rocket-powered flight when it soared to the edge of space, 51.4 miles (82 km) above sea level. On February 22, 2019, the aircraft repeated the feat, this time with its first passenger – the company's astronaut trainer Beth Moses - on board.
