Tamed Dragon supply ship arrives at space station

CAPE CANAVERAL, Fla. (AP) — A privately owned Dragon capsule arrived at the International Space Station on Sunday, delivering a ton of supplies with high-flying finesse after a shaky start to the mission.

The Dragon’s arrival was one day late but especially sweet — and not because of the fresh fruit on board for the station astronauts who snared the capsule.

SpaceX, the California-based company founded by billionaire Elon Musk, had to struggle with the Dragon following its launch Friday from Cape Canaveral. A clogged pressure line or stuck valve prevented thrusters from working, and it took flight controllers several hours to gain control and salvage the mission.

In the end, the Dragon approached the orbiting lab with its 1-ton load about as smoothly as could be expected, with all of its thrusters, or little maneuvering rockets, operating perfectly. The capture occurred as the two spacecraft zoomed 250 miles above Ukraine.

“As they say, it’s not where you start, but where you finish that counts,” said space station commander Kevin Ford, “and you guys really finished this one on the mark.”

He added: “We’ve got lots of science on there to bring aboard and get done. So congratulations to all of you.”

Among the items on board: 640 seeds of a flowering weed used for research, mouse stem cells, food and clothes for the six men on board the space station, trash bags, computer equipment, air purifiers, spacewalking tools and batteries. The company also tucked away apples and other fresh treats from an employee’s family orchard.

The Dragon will remain at the space station for most of March before returning to Earth with science samples, empty food containers and old equipment.

SpaceXSpace Exploration Technologies Corp. — has a $1.6 billion contract with NASA to keep the station well stocked. The contract calls for 12 supply runs; this was the second in that series.

This is the third time, however, that a Dragon has visited the space station. The previous two capsules had no trouble reaching their destination. Company officials promise a thorough investigation into what went wrong this time; if the thrusters had not been activated, the capsule would have been lost.

Mr. Ford said everything about Sunday’s rendezvous ended up being “fantastic.”

“There sure were some big smiles all around here,” NASA’s Mission Control replied from Houston.

The actual anchoring of the Dragon to the space station, 2½ hours after its arrival, also unfolded without a hitch.

“The Dragon is ours!” Canadian astronaut Chris Hadfield announced via Twitter.

In a tweet following Friday’s nerve-racking drama, Mr. Musk said, “Just want to say thanks to @NASA for being the world’s coolest customer. Looking forward to delivering the goods!”
