A privately built robotic space capsule filled with supplies for the International Space Station successfully arrived at the orbiting laboratory early Sunday (March 3), one day later than planned due to a temporary thruster glitch. <\/p>\n
The unmanned Dragon cargo capsule, built by the private spaceflight company SpaceX, was captured by astronauts wielding the space station's robotic arm at 5:31 a.m. EST (1031 GMT) as both spacecraft sailed 243 miles (391 kilometers) above Northern Ukraine. <\/p>\n
\"Congratulations to the SpaceX and the Dragon team in Houston and in California,\" space station commander Kevin Ford, a NASA astronaut, radioed Mission Control after the successful Dragon arrival. \"They say it is not where you start, but where you finish that counts and you guys really finished this one on the mark. You're aboard and we've got lots of science on there to bring aboard and get done.\" <\/p>\n
SpaceX launched the Dragon capsule toward the space station on Friday (March 1), with the spacecraft riding the company's Falcon 9 rocket into orbit. While the launch was smooth, the Dragon capsule ran into trouble after it separated from the Falcon 9 rocket when three of four thruster pods did not activate as planned. <\/p>\n
After several hours of troubleshooting, SpaceX engineers isolated the glitch to a pressurization problem in the thruster system and devised a fix that solved the problem. Because of the time needed for the fix, the Dragon capsule missed its initial rendezvous slated for Saturday (March 2). [See photos of the Dragon's space station arrival] <\/p>\n
The spacecraft's arrival on Sunday, however, appeared to go extremely smoothly, with the capsule being captured by the station's robotic arm an hour earlier than scheduled. <\/p>\n
\"That was a brilliant capture,\" NASA astronaut Kate Rubins radioed the station crew from Mission Control in Houston. <\/p>\n
The Dragon space capsule is packed with 1,200 pounds (544 kilograms) for the International Space Station, a haul that includes fresh food, science experiments and other vital equipment. The capsule is also carrying two grapple bars for the station's exterior inside an unpressurized \"trunk\" a storage compartment in a cylindrical section of the spacecraft below its re-entry capsule. <\/p>\n
This mission is SpaceX's third flight to the space station and second official cargo delivery under a $1.6 billion deal with NASA for resupply flights. Under that contract, the Hawthorne, Calif.-based SpaceX has agreed to provide at least 12 Dragon supply flights to the space station. <\/p>\n
SpaceX launched its first Dragon to the space station last May during a demonstration flight, and followed that success with an official cargo delivery in October. <\/p>\n
