Space Station Crew Excited for 1st Private Spaceship Visit

The three astronauts living on the International Space Station are ready to usher in a new era at their orbiting home: the first arrival of a privately built spacecraft.

The Hawthorne, Calif.-based commercial spaceflight company Space Exploration Technologies, or SpaceX,  is preparing to launch its Dragon capsule toward the station May 7 on an unmanned mission to deliver supplies and demonstrate its own abilities. The flight is the Dragon capsule's maiden voyage for SpaceX under a NASA program aimed at buying cargo delivery services from private companies, now that the agency's space shuttles are retired.

The three astronauts on the space station are vital to the SpaceX capsule's safe arrival; the job falls to them to use the space station's robotic arm to grab the craft as it approaches (Dragon does not carry the tools that would allow it to dock itself).

"It feels very good to be part of that and I look forward to it very much," European Space Agency astronaut Andre Kuipers, who hails from the Netherlands, told the Associated Press Tuesday (May 1) during an interview broadcast on NASA TV. "This is the start of a real new era and I expect there's a lot more to come."

"We were practicing a bit this morning," Pettit said. "We do it over and over and over again. We are getting prepared for our visitor next week."

Dragon is slated to launch next week aboard a SpaceX Falcon 9 booster rocket from Cape Canaveral Air Force Station in Florida. It will spend about three days catching up to the space laboratory in orbit and undergoing checkouts, and then will be pulled in to make a docking with the station. The capsule will carry food, clothing, supplies and scientific equipment for the astronauts, though none of it is critical, since this mission is officially a test flight.

However, NASA officials are hoping things go smoothly to pave the way for a more regular delivery service by SpaceX, as well as another NASA-contracted company, Orbital Sciences Corp. of Dulles, Va. Orbital is due to fly its Cygnus spacecraft on a first demonstration flight later this year.

Overall, NASA has contracted SpaceX to fly 12 more cargo delivery flights for a total of $1.6 billion. Orbital has received an order for eight flights for $1.9 billion.

Pettit compared this new commercial-government partnership to what happened with forts in the Old West. While the U.S. government sponsored the forts and defined the mission, commercial outfitters ran the wagon trains that supplied the forts.

"Now government-run agencies like NASA can concentrate on the frontier aspect of being in space," Pettit said. "They can define what we're doing and then we can have the commercial entities supply us the gods and services we need in order to do the mission."
