Summary The first commercial cargo run to the International Space Station has been put off until spring.
SpaceX planned to launch its unmanned supply ship from Cape Canaveral in Florida on Feb. 7. But the company said more testing was needed with the spacecraft, named Dragon. On Friday, officials confirmed the launch would not occur until late March.NASA closed out its 30-year shuttle program last July.Space station commander Daniel Burbank said as much as hed like to take part in the historic event, its important that SpaceX fly when its ready. Burbank will return to Earth in mid-March.If thats not to be during our mission, then thats OK, Burbank said in an interview Friday with The Associated Press.Weve got plenty of other things to occupy us.Just over a year ago, the California-based Space Exploration Technologies Corp. launched a test version of the capsule, becoming the first private business to send a spacecraft into orbit and return it safely. NASA is counting on companies like SpaceX to keep the station stocked, now that the shuttles are retired.Until then, the Russian, European and Japanese space agencies all government entities have been sending up regular shipments to the orbiting outpost.SpaceX run by PayPal co-founder Elon Musk is one of several companies vying for space station visiting privileges. Its long-term goal is to modify its Falcon rocket and Dragon capsule to ferry astronauts to the station.In the meantime, Americans are buying seats on Russian Soyuz spacecraft.SpaceX spokeswoman Kirstin Grantham pointed out that this is a developmental program for her company, and everyone wants it to be a complete success.It may take a little more time, but when it happens, its going to be amazing, she said.This first Dragon capsule to visit the space station will carry several hundred pounds of astronaut provisions nothing crucial, in case of a failure.Astronauts aboard the space station will use a huge robot arm to grab and berth the Dragon.This will be one step in the long road to human expansion off of the planet into low-Earth orbit and beyond, space station astronaut Donald Pettit said Friday.The beauty of the Dragon is that it will be able to return scientific samples to Earth, Burbank noted. None of the other countries supply ships can do that; they burn up on re-entry.Americans Burbank and Pettit, three Russians and a Dutchman make up the six-man crew.I think were getting by OK, Burbank said, but we need to have as much up-mass and down-mass capability as we can to support space station operations at the level we need it.
