Blue Origin is counting down to the launch of its NS-21 space tourist mission on June 4 from the company's West Texas-based Launch Site One near Van Horn. Liftoff is set for 9 a.m. EDT (1300 GMT), with a webcast beginning one hour before launch time at 8 a.m. EDT (1200 GMT).

The mission has been delayed since May 20, when technical issues and the need for more booster checks on its New Shepard rocket prompted the company to stand down from the mission. 

NS-21 will launch six passengers on a short suborbital spaceflight, with the New Shepard booster returning to Earth for a vertical landing and the crew capsule parachuting to the surface shortly afterward. 

The crew of Blue Origin's NS-21 mission includes:
