Boeing and SpaceX to to carry American astronauts to space

Boeing and the Space Exploration Technologies Corp. are the winners in the competition to carry Americans astronauts to the International Space Station, Nasa announced yesterday.

The awards reflect a fundamental shift in Nasa’s human spaceflight programme, relying on private companies rather than the traditional hands-on approach, in which the space agency designed and operated the spacecraft. The first flights could take off as soon as 2017.

“We have credible plans for both companies to get there by that period of time,” Kathryn Lueders, the manager for Nasa’s commercial crew program, said during a news conference yesterday. “We will not sacrifice crew safety for that goal.”

Boeing received a $4.2 billion (€3.2 billion) contract. Space Exploration Technologies - better known as SpaceX, of Hawthorne, California - received a $2.6 billion (€2 billion) contract .

"Today we're one step closer to launching our astronauts from US soil on American spacecraft and ending the nation's sole reliance on Russia, " said Charles Bolden, the Nasa administrator. Since the retirement of the space shuttles in 2011, Nasa has had no way to send its astronauts to orbit, relying on the venerable Russian Soyuz spacecraft for transportation to and from the International Space Station at a cost of $70 million (€54 million) per seat.

That became a politically uncomfortable arrangement after Russia's annexation of Crimea and support of pro-Russian separatists in Ukraine.

John Mulholland, the commercial crew manager at Boeing, said Nasa called just before the news conference to tell him his company had won the competition. “It was a real mixture of inspiration and humbleness,” he said. Under the contracts, Boeing and SpaceX will finish development of their spacecraft. Boeing’s CST-100 capsule, configured to carry up to five people, will launch on an Atlas 5 rocket. SpaceX’s Dragon 2 capsule, a sleeker, updated version of the capsule already carrying cargo to the space station, will ride on top of the company’s Falcon 9 rocket.

“We basically awarded based on the proposal that we were given,” Ms Lueders said. A third company, Sierra Nevada Space Systems, of Louisville, Colorado, had proposed a design that resembled a mini-space shuttle that would land on aircraft runways. Much of the money allotted to SpaceX and Boeing in the next three years will go to meeting Nasa’s certification requirements for performance and safety. As part of that process, each company will conduct a test flight to the space station with a crew that is to include at least one Nasa astronaut.

Once the companies are certified, Nasa has promised each at least two missions. The full contract amounts will be paid if Nasa orders six missions from each company. Mulholland said Nasa had yet to discuss its plans in detail, but space agency officials in the past have said they expected two flights a year to the space station. If flights begin in 2017 and each company flies one a year, the contracts could run through 2023.

With each flight taking four astronauts, the space station crew will be able to grow to seven, from six. Nasa officials said that additional crew member would allow it to double the amount of science conducted. The Boeing and SpaceX capsules will also serve as lifeboats for the space station crew in case of an emergency.

The commercial crew program came out of the cancellation of an earlier programme started under the Bush administration to send astronauts back to the moon. That effort relied on two rockets designed and operated by Nasa. The Obama administration concluded that approach was too expensive and cancelled the rockets. Instead, the Obama administration built upon another Bush-era Nasa initiative.

The hope is that the commercial approach will spur a space travel industry far larger than just Nasa. Boeing, for example, hopes that the fifth seat in its CST-100 capsule could carry a paying tourist to the space station. “We’ll be working with NASA to try and bring that to reality,” Mr Mulholland said. Both Boeing and SpaceX are working with Bigelow Aerospace, a Las Vegas company that plans to launch private space stations into orbit, to be leased to nations or companies.
