Oct 25 (Reuters) - Billionaire Jeff Bezos-owned Blue Origin on Monday unveiled plans to develop a commercial space station called "Orbital Reef" with Boeing (BA.N), aiming to launch the spacecraft in the second half of this decade. The venture will be built in partnership with Sierra Space, the spaceflight wing of defense contractor Sierra Nevada Corp, and will be backed by Redwire Space, Genesis Engineering Solutions and Arizona State University. Orbital Reef will be operated as a "mixed use business park", and plans to provide the infrastructure needed to scale economic activity and open new markets in space, Blue Origin and Sierra Space said. "Seasoned space agencies, high-tech consortia, sovereign nations without space programs, media and travel companies, funded entrepreneurs and sponsored inventors, and future-minded investors all have a place on Orbital Reef," the companies said in a statement.
