CAPE CANAVERAL, Fla. (AP) — A commercial cargo ship rocketed into orbit Sunday in pursuit of the International Space Station, the first of a dozen supply runs under a mega-contract with NASA.
It was the second launch of a Dragon capsule to the orbiting lab by the California-based SpaceX company. The first was last spring.
This time was no test flight, however, and the spacecraft carried 1,000 pounds of key science experiments and other precious gear on this truly operational mission. There was also a personal touch: chocolate-vanilla swirl ice cream tucked in a freezer for the three station residents.
The company's unmanned Falcon rocket roared into the night sky right on time, putting SpaceX on track to reach the space station Wednesday. The complex was soaring southwest of Tasmania when the Falcon took flight.
Officials declared the launch a success, despite a problem with one of the nine first-stage engines. The rocket put Dragon in its intended orbit, said the billionaire founder and chief executive officer of SpaceX, Elon Musk.
"It's driving its way to station, so that's just awesome," noted SpaceX President Gwynne Shotwell.
In more good news, a piece of space junk was no longer threatening the station, and NASA could focus entirely on the delivery mission.
NASA is counting on private business to restock the space station, now that the shuttles have retired to museums. The space agency has a $1.6 billion contract with SpaceX for 12 resupply missions.
Especially exciting for NASA is the fact that the Dragon will return twice as much cargo as it took up, including a stockpile of astronauts' blood and urine samples. The samples — nearly 500 of them — have been stashed in freezers since Atlantis made the last shuttle flight in July 2011.
The Dragon will spend close to three weeks at the space station before being released and parachuting into the Pacific at the end of October. By then, the space station should be back up to a full crew of six.
None of the Russian, European or Japanese cargo ships can bring anything back; they're destroyed during re-entry. The Russian Soyuz crew capsules have limited room for anything besides people.
