Dragon arrives at space station in historic 1st

The privately-financed capsule is a milestone in commercial space-flight

CAPE CANAVERAL, Fla. (AP) — The privately bankrolled Dragon capsule made a historic arrival at the International Space Station on Friday, captured by astronauts wielding a giant robot arm.

SpaceX is the first private company to attempt such a feat: the first commercial cargo delivery into the cosmos.

"Just awesome," said SpaceX's billionaire maestro, Elon Musk, of PayPal fame.

U.S. astronaut Donald Pettit used the space station's 58-foot robot arm to snare the gleaming white Dragon after a few hours of extra checks and maneuvers. The two vessels came together while sailing above Australia.

"Looks like we've got us a dragon by the tail," Pettit announced from 250 miles up once he locked onto Dragon's docking mechanism.

"You've made a lot of folks happy down here over in Hawthorne and right here in Houston," radioed NASA's Mission Control. "Great job guys."

NASA controllers clapped as their counterparts at SpaceX's control center in Hawthorne, Calif. — including Musk — lifted their arms in triumph and jumped out of their seats to exchange high fives. The two control rooms worked together, as equal partners, to pull off the feat.

Although cargo hauls have become routine, Friday's linkup was significant in that an individual company pulled it off. That chore was previously reserved for a small, elite group of government agencies.

Not only that, the SpaceX Dragon is designed to safely return items, a huge benefit that disappeared with NASA's space shuttles. The vessel is the first U.S. craft to visit the station since the final shuttle flight last summer.

The unmanned capsule is carrying 1,000 pounds of supplies on this unprecedented test flight.

Two hours after the capture, the crew attached the Dragon to the space station as the congratulations poured in. They'll start unpacking the capsule on Saturday.

"Now that a U.S. company has proven its ability to resupply the space station, it opens a new frontier for commercial opportunities in space — and new job creation opportunities right here in the U.S.," NASA Administrator Charles Bolden said in a statement.

After this test flight, SpaceX — officially known as Space Exploration Technologies Corp. — has a contract to make a dozen delivery runs. It is one of several companies vying for NASA's cargo business and a chance to launch Americans from U.S. soil.

SpaceX launched the capsule from Cape Canaveral on Tuesday with its Falcon 9 rocket. On Thursday, the Dragon capsule came within 1½ miles of the space station in a practice fly-by. It returned to the neighborhood early Friday so Pettit, along with Dutch astronaut Andre Kuipers could capture it with the station's robot arm.

First, the capsule went through a series of stop-and-go demonstrations to prove it was under good operating control.

NASA ordered extra checks of the Dragon's imaging systems as the capsule drew ever closer to the space station, putting the entire operation slightly behind schedule. At one point, SpaceX controllers ordered a retreat because of a problem with on-board tracking sensors.

Given that the Dragon is a brand new type of vehicle and this is a test flight, the space agency insisted on proceeding cautiously. A collision by vehicles traveling at orbital speed — 17,500 mph — could prove disastrous for the space station.

President Barack Obama is pushing commercial ventures in orbit so NASA can concentrate on grander destinations like asteroids and Mars. Obama's chief scientific advisor, John Holdren, called Friday's linkup "an achievement of historic scientific and technological."

"It's essential we maintain such competition and fully support this burgeoning and capable industry to get U.S. astronauts back on American launch vehicles as soon as possible," he said in a statement.

Without the shuttle, NASA astronauts must go through Russia, an expensive and embarrassing situation for the U.S. after a half-century of orbital self-sufficiency. Once companies master supply runs, they hope to tackle astronaut ferry runs.

Musk, who founded SpaceX a decade ago and helped create PayPal, said he can have astronauts riding his Dragon capsules to orbit in three or four years.

The space station has been relying on Russian, Japanese and European cargo ships for supplies ever since the shuttles retired. None of those, however, can bring anything of value back; they're simply loaded with trash and burn up in the atmosphere.

By contrast, the Dragon is designed to safely re-enter the atmosphere, parachuting into the ocean like the Mercury, Gemini and Apollo capsules did back in the 1960s. Assuming all goes well Friday, the space station's six-man crew will release the Dragon next Thursday after filling it with science experiments and equipment.

Going into Tuesday's launch of this Dragon, NASA had contributed $381 million to SpaceX in seed money. The company has invested more than $1 billion in this commercial effort over the past 10 years.
