The rocket company is targeting July 20 for its first suborbital sightseeing trip on its spacecraft, a landmark moment in a competition to usher in a new era of private commercial space travel.
The New Shepard rocket-and-capsule combo is designed to autonomously fly six passengers more than 62 miles (100 km) above Earth into suborbital space.
Reuters reported in 2018 that Blue Origin was planning to charge passengers at least $200,000 for the ride, based on an appraisal of rival plans from billionaire Richard Branson‘s Virgin Galactic Holdings Inc and other considerations, though its thinking may have changed.
