Bezos' Blue Origin to run 'astronaut rehearsal' during NS-15 launch

Jeff Bezos-owned Blue Origin plans to run an "astronaut rehearsal", in preparation for human space flight, during the launch of its New Shepard NS-15 flight on April 14. Blue Origin personnel will board the flight prior to launch, go through pre-flight operations and then return to the capsule once it has landed to rehearse hatch opening, and exiting the capsule.
