The space transportation company managed by Amazon.com Inc. Chief Executive Jeff Bezos reached another lucrative steppingstone in its attempt to become an established launcher of US civilian and national security payloads.The National Aeronautics and Space Administration on Wednesday named Blue Origin Federation LLC’s New Glenn Rocket-a 310 foot reusable booster that isn’t estimated to make its initial flight until 2021-as one of its potential launch providers for scientific missions later in the decade.The agency stated that no specific contracts had been awarded to Blue Origin, but the announcement for the first time makes the closely held company entitled for such Nasa business. Under the arrangement, the company Mr. Bezos founded almost 20 years ago will be granted to use New Glenn, approximately six stories taller than the rival rockets, to compete for awards. Various members of Nasa will be able to design spacecraft to take advantage of New Glenn’s power and other features, including its capacity to transport bigger payload columns than other rockets.
