SpaceX Dragon Capsule Delivers Fresh Supplies to Space Station

The capsule was carried Jan. 10 atop a Falcon 9 rocket that lifted off from Cape Canaveral. After launch, the rocket came down as planned on a drone ship but hit a bit too hard

SpaceX's robotic Dragon resupply spacecraft has arrived at the International Space Station after a two-day orbitalchase.

NASA astronaut Barry "Butch" Wilmore, commander of the station's current Expedition 42, grappled Dragon using the orbiting outpost's huge robotic arm at 5:54 a.m. EST (1054 GMT) on Monday (Jan. 12). The capsule was installed on the Earth-facing port of the station's Harmony module three hours later.

The astronauts can now begin offloading the 5,200 pounds (2,360 kilograms) of food, spare parts andscientificexperiments that Dragon brought up on this mission, the fifth of 12 unmanned cargo flights SpaceX plans to fly to the space station under a $1.6 billion deal with NASA.

SpaceX launched the Dragon capsuleearly Saturday (Jan. 10) atop aFalcon 9 rocketthat lifted off from Florida's Cape CanaveralAir Force Station. After the rocket sent Dragon on its way, SpaceX attempted to bring the Falcon 9's first stage back to Earth for a pinpoint landing on an "autonomous spaceport drone ship" in the Atlantic Ocean, as part of the company's effort to develop reusable-rockettechnology.

The rocket stage came down on target buthit the drone ship too hard Saturday. SpaceX will try the bold maneuver again on future launches, company representatives said.

Dragon is unmanned, but the capsule did bring a number of living passengers up to the orbitinglab. For example, it hauled an experiment that will look at how microgravity affects the wound-healing abilities of flatworms, and two others that will study howplantsgrow in space.

The cargo capsule also delivered a NASA instrument called CATS (short for Cloud-Aerosol Transport System), which will be affixed to the station's exterior and then use a laser to measure the distribution of clouds, haze, dust and pollution in Earth's atmosphere.

Dragon will stay attached to the International Space Station for one month, NASA officials said. It will depart on Feb. 10, returning to Earth with a splashdown in the Pacific Ocean off the coast of California, where SpaceX will retrieve the capsule by boat.
