Aerospace manufacturer Blue Origin will delay its next sub-orbital spaceflight because of a vehicle issue, the company announced Wednesday. Originally scheduled to take place Friday, the launch would have been the fifth manned flight for the Washington state-based company's New Shephard space vehicle. "During our final vehicle checkouts, we observed one of New Shepard's backup systems was not meeting our expectations for performance. In an abundance of caution, we will be delaying the #NS21 launch originally scheduled for Friday. Stay tuned for further updates," the company said in a statement Wednesday. The company did not speculate on a new launch date. In late March, the company launched its fourth crewed mission, carrying a crew of six to the edge of space and back. That flight was originally supposed to include SNL actor Pete Davidson, who was invited as a guest, to join five paying customers. The comedian was unable to make the flight after it was re-scheduled and was replaced by Blue Origin suborbital rocket architect Gary Lai. When the flight does eventually lift off, Evan Dick will become the first-ever repeat New Shepard crewmember. Dick previously flew on the NS-19 mission, which launched Dec. 11, 2021. New Shepherd uses reusable liquid rocket engines, as well as a reusable capsule. Source: United Press International
Rocket engine exhaust pollution extends high into Earth's atmosphere Washington DC (SPX) May 18, 2022 Reusable space technology has led to a rise in space transportation at a lower cost, as popularized by commercial spaceflights of companies like SpaceX and Virgin Galactic. What is poorly understood, however, is rockets' propulsion emissions creating significant heating and compositional changes in the atmosphere. In Physics of Fluids, by AIP Publishing, researchers from the University of Nicosia in Cyprus assessed the potential impact of a rocket launch on atmospheric pollution by investigating t ... read more
