In race to replace space shuttles, NASA boosts four front-runners
NASA is turning to private companies to replace the space shuttles, and it will give four proposals from the likes of Boeing and SpaceX $269 million this year.
Efforts to develop new spacecraft to ferry astronauts to and from the International Space Station have picked up fresh momentum thanks to agreements NASA has reached with four companies aiming to become the Checker Taxis to low-Earth orbit.Skip to next paragraph

Space-agency officials announced late Monday that they would be spending $269.3 million this year to help four companies refine their concepts and hardware. The quartet, which was whittled down from a list of 22 proposals, ranges from long-time aerospace player Boeing to a new generation of aerospace entrepreneurs, including Space Exploration Technologies (SpaceX) and Blue Origins, founded by Amazon.com's Jeff Bezos.
The announcement comes at a critical time in the evolution of the US human-spaceflight program.
On April 29, the space shuttle Endeavour is scheduled to lift off from the Kennedy Space Center in Florida on its final mission. In late June or early July, Atlantis makes its farewell flight, bringing the 30-year shuttle program to a close. With no US replacement for the shuttle standing ready to pick up the baton, US astronauts will be traveling to and from the station in Russian spacecraft at least through 2016.
Eventually, though, the Obama administration's plan is to have private companies take up where the shuttle left off – ferrying equipment and crew to the space station and low-Earth orbit. NASA, then, would be free to focus on more ambitious missions farther into space.
Some analysts suggest it would be cheaper to continue piggybacking with the Russians into low-Earth orbit, while some members of Congress are loath to have NASA cede that task to anyone else – the Russians or private contractors. But the with its announcement Monday, NASA took another step forward on the president's plans.
And the winners are...
It is as yet unclear how many of the proposals NASA might ultimately choose. But they include:
• SpaceX, based in Hawthorne, Calif, is slated to get $75 million to turn its Dragon capsule into a vehicle fit for humans as well as cargo. The capsule is designed to sit atop the company's new Falcon 9 rocket. Space X has had one successful test flight of the Falcon 9 and Dragon capsule in December. The rocket delivered the capsule to orbit, and after two trips around the Earth, the capsule splashed down in the Pacific off of Mexico and was recovered. SpaceX, which already is under a $1.6 billion contract with NASA to deliver cargo to the space station, aims to ferry its first crew in 2014.
