Sunday's launching marked Unity's 22nd test flight, its fourth trip to space, Virgin's first with a six-person crew on board and the first for Branson, who beat Bezos into space by nine days.
The seventh satellite on today's flight is Spire Global's Adler-1, which will study the environment in low Earth orbit.
Virgin Galactic owner Richard Branson rocketed into space Sunday, an edge-of-the-seat sub-orbital test flight intended to demonstrate his company's air-launched spaceplane is who can afford the ultimate thrill ride.
