“Virgin Galactic Founder Sir Richard Branson revealed that the company has now accepted deposits for suborbital flights on SpaceShipTwo from 529 future astronauts, a number greater than the total count of people who have been to space throughout human history.”The price for being one of these pioneers was $200K USD. However, reservations for future sub-orbital flights are expected to be $20K. Orbital flights are also being planned.
Blue Origin is maturing the design of the Space Vehicle in partnership with the National Aeronautics and Space Administration (NASA) under the agency’s Commercial Crew Development (CCDev) program. The (SRR) review assessed the Space Vehicle’s ability to meet safety and mission requirements, and evaluated the technical readiness of the design, the concept of operations, the feasibility of project development plans, and planned verification activities. The review also included results from recently completed wind tunnel tests of the biconic shape, validating the vehicle’s aerodynamic design, stability and cross-range.The New Shepard is a vertical launch assembly, currently using the Atlas V rocket. Think Apollo, Gemini, Galilleo, and the Shuttle. By contrast, it should be noted that Virgin Galactic’s SpaceShipTwo uses an in-flight launch system - jetting off from a heavy-lift aircraft, WhiteKnightTwo, propelled by a stage rocket called LauncherOne. If you saw the June launch of NuSTAR 1 from the carrier aircraft, Stargazer, you’ll have an idea of how WhiteKnightTwo operates.
Driven by the competition of the Cold War, on July 29, 1958, President Dwight D. Eisenhower signed the National Aeronautics and Space Act, providing for research into the problems of flight within Earth’s atmosphere and in space. The act inaugurated a new civilian agency designated the National Aeronautics and Space Administration (NASA). The agency began operations on Oct. 1, 1958.
