Computerworld - A robotic arm onboard the International Space Station reached out and grabbed hold of the SpaceX Dragon cargo ship today, attaching the commercial craft to the station.
The station's Canadarm captured the spacecraft at 6:56 a.m. Eastern time as it flew within about 32 feet of the orbiter, which was traveling 250 miles above the Pacific Ocean, just west of Baja California. At 9:03 a.m., the Dragon was attached to the space station.
Calling it a "key milestone in a new era of commercial spaceflight, NASA announced that the hatch between the SpaceX spacecraft and the space station was opened this afternoon.
The Dragon delivered 882 lbs. of supplies to the station, including 260 lbs. of crew supplies, 390 lbs. of scientific research equipment and 225 lbs. of hardware.
"This marks the start of a new era of exploration for the United States, one where we will reduce the cost of missions to low-Earth orbit so we can focus our resources on deep space human missions back around the moon, to an asteroid and eventually to Mars," NASA Administrator Charles Bolden said in a statement.
The SpaceX Falcon 9 rocket blasted off from Florida's Cape Canaveral Air Force Station on Sunday night, carrying the Dragon capsule into orbit.
The first official commercial mission to resupply the space station opens a new chapter in U.S. space exploration.
In May, SpaceX successfully completed a trial cargo flight to the space station.
This week's effort marks the beginning of the company's plan to launch a dozen operational missions to the station under a four-year, $1.6 billion contract with NASA.
The Dragon spacecraft is scheduled to spend 18 days attached to the station before returning for a splashdown in the Pacific Ocean off the coast of Southern California.
Dragon is scheduled to bring back a total of 1,673 lbs. of used supplies and equipment.
NASA noted that the ability to pick up cargo, such as concluded scientific experiments and waste, and return it to Earth is critical to running the space station. The space agency noted that scientific samples and other materials have largely been piling up on the space station since NASA retired its fleet of space shuttles in the summer of 2011.
NASA now depends on companies like SpaceX to ferry astronauts and cargo to and from the space station.
As the space agency looks for assistance for its short-haul missions to the space station, it will focus on building high-powered engines and robotics, and prepare for more ambitious missions to the moon, the asteroids and Mars.
