Dragon captured, berthed at space station

SpaceX's CRS-5 Dragon spacecraft completed its two-day trip to the International Space Station on Monday morning (Jan. 12).

NASA astronaut Butch Wilmore and European Space Agency (ESA) astronaut Samantha Cristoforetti were in the space station's Cupola when they used the Canadarm2 robotic arm to capture the Dragon at 4:54 a.m. CST (1054 GMT). The two spacecraft were flying 262 miles (420 km) above the Mediterranean Sea, just southeast of Barcelona, when the grapple was achieved.

"Congratulations and nice job," said Wilmore, the commander of the station's Expedition 42 crew. "It's been a couple of days getting here, and it's nice to have it on-board, and we'll be digging in soon."

Flight controllers at NASA's ISS Mission Control in Houston remotely operated the station's arm to berth the Dragon to the Harmony node. The cargo capsule was secured by two sets of bolts to the side of the module at 7:54 a.m. CST (1354 GMT).

The Dragon will spend the next four weeks attached to the outpost as the Expedition 42 crew unloads it of supplies and research equipment before repacking it with completed experiments, spent hardware and refuse for its return to a splashdown and recovery on Earth in early February.

The CRS-5 Dragon's arrival marked the sixth time that a Dragon has berthed to the space station, the 74th cargo freighter to resupply the outpost and the 155th mission to the orbiting laboratory.

Dragon departs space station

SpaceX's CRS-5 Dragon spacecraft is now on its way back to Earth.

The unmanned cargo freighter was released by the station's robotic arm at 1:10 p.m. CST (1910 GMT) on Tuesday (Feb. 10) as the two spacecraft orbited over Australia. The Dragon was detached from the Earth-facing side of the station's Harmony module earlier in the day.

The Dragon capsule will execute three thruster firings to move it a safe distance from the space station for its deorbit burn at 5:49 p.m. CST. The spacecraft is expected to splash down in the Pacific Ocean off the coast of Long Beach, California around 6:44 p.m. CST (0044 GMT).

The craft is returning to Earth with about 3,700 pounds (1,700 kg) of cargo, including science samples from physiology research, biology and biotechnology studies and physical science investigations.

Critical NASA Science Returns to Earth aboard SpaceX Dragon Spacecraft

SpaceX's Dragon cargo spacecraft splashed down in the Pacific Ocean about 7:44 p.m. EST Tuesday (Feb. 10) 259 miles southwest of Long Beach, California, with nearly 3,700 pounds of NASA cargo, science and first-of-its-kind technology demonstration samples from the International Space Station.

The Dragon spacecraft will be taken by ship to Long Beach, where some cargo will be removed and returned to NASA. Dragon will then be prepared for a return trip to SpaceX's test facility in McGregor, Texas, for processing.

"The ability to resupply and return this critical research continues to be an invaluable asset for the researchers here on Earth using the International Space Station as their laboratory in orbit," said Kirt Costello, deputy chief scientist for the International Space Station Program at NASA’s Johnson Space Center in Houston.

Flight controllers in the Mission Control Center at Johnson robotically positioned Dragon safely away from its docking port earlier Tuesday, where it was released for its deorbit maneuver, sending it on its way to a parachute-assisted splashdown.

Among the returned investigations were printed parts and hardware from the first technology demonstration of 3-D printing in space. The 3-D printer demonstration used relatively low-temperature plastic feedstock on the space station. The test phase ended with a printed ratchet wrench made with a design file transmitted from Earth to the printer.

"Experiments like 3-D printing in space demonstrate important capabilities that allow NASA and humanity to proceed farther on the journey to Mars,” Costello said. “Other investigations such as those focused on protein crystal growth take advantage of the unique microgravity environment and offer us new avenues to investigate troubling diseases back on Earth."

Dragon also returned samples, hardware and data from several biology and biotechnology studies performed on the station. The Advancing Membrane Protein Crystallization by Using Microgravity investigation explored the production of high-quality crystals of the cystic fibrosis protein and other closely related proteins. Because many medically relevant proteins are difficult to crystalize on Earth, researchers attempt to grow them in space to help determine their shape and structure with the hope of improving drug therapies for cystic fibrosis, a genetic disorder that causes severe damage to the lungs and digestive system.

Samples from the Advanced Plant Experiments 03-1 will help scientists better understand the effects of microgravity on the development of roots and cells on plant seedlings. Researchers will conduct a detailed analysis of the returned plant samples to determine the molecular and genetic mechanisms that control plant development in microgravity. With this knowledge, scientists may be able to improve agricultural and bioenergy research on Earth, leading to crops that use resources more efficiently.

Dragon is the only space station resupply spacecraft able to return a significant amount of cargo to Earth. The spacecraft lifted off atop a SpaceX Falcon 9 rocket from Cape Canaveral Air Force Station in Florida on Jan. 10 carrying more than 5,000 pounds of supplies and elements to support 256 scientific investigations and arrived at the orbiting complex two days later on Jan. 12. The mission was the fifth of at least 12 cargo resupply trips SpaceX will make to the orbiting outpost through 2016 under NASA's Commercial Resupply Services contract.
