NEW YORK — A privately launched cargo ship packed with late Christmas presents and space-traveling ants linked up with the international space Station Jan. 12 in a milestone delivery mission for the astronauts onboard.
Space station astronauts used a robotic arm to capture the unmanned Cygnus spacecraft and attach it to an open docking port as both spacecraft sailed 418 kilometers above Earth. The special delivery comes courtesy of the Dulles, Va.-company Orbital Sciences Corp., which launched the Cygnus spacecraft Jan. 9 to make its first commercial resupply mission to the station for NASA.
The Cygnus spacecraft carried 1,260 kilograms of gear for the space station crew, including fresh fruit and Christmas gifts. It is also delivered eight ant farms to the station for weightlessness research, 23 student experiments and small cubesat satellites among the science gear.
“The cargo is comprised of vital science experiments, crew provisions, spare parts and other hardware,” NASA officials said in a statement. “One newly arrived investigation will study the decreased effectiveness of antibiotics during spaceflight. Another will examine how different fuel samples burn in microgravity, which could inform future design for spacecraft materials.”
The mission was originally slated for a mid-December launch, but Orbital Sciences officials and NASA delayed the flight to January when a cooling system malfunction on the station forced astronauts to perform emergency spacewalk repairs.
Bitter cold temperatures and a surprise solar flare added extra delays, with the Cygnus spacecraft finally launching Jan. 9 from the Mid-Atlantic Regional Spaceport’s Pad-0A at NASA’s Wallops Flight Facility on Wallops Island, Va. It lifted off atop an Orbital-built Antares rocket.
Despite the delay, Cygnus’ arrival appeared to go flawlessly, with astronauts Mike Hopkins of NASA and Koichi Wakata of Japan — both flight engineers with the station’s six-man Expedition 38 crew — easily latching onto the Cygnus spacecraft with the station’s robotic arm.
“Our first mission under the [Commercial Resupply Services] contract with NASA was flawlessly executed by our Antares and Cygnus operations team, from the picture-perfect launch from NASA’s Wallops Flight Facility to the rendezvous, capture and berthing at the space station this morning,” Orbital President and Chief Executive David W. Thompson said in a statement.
Orbital’s $1.9 billion cargo delivery deal with NASA calls for the company to launch at least eight resupply missions to the space station by 2016 to ferry a total of 18,000 kilograms of supplies to the orbital lab. The company’s Cygnus spacecraft are bus-size disposable spacecraft designed to deliver supplies to the station, and then haul away trash and unneeded items for disposable. A Cygnus spacecraft visited the station last September in a debut test flight, but that demonstration mission did not carry a full cargo load.
The Cygnus currently at the station, known as Orb-1, is due to depart the orbiting lab Feb. 18 and be intentionally destroyed Feb. 19, when it is scheduled to burn up in Earth’s atmosphere.
Orbital officials named the Orb-1 Cygnus the Spaceship C. Gordon Fullerton in honor of the late NASA astronaut Gordon Fullerton, who died last year.
“Very pleased the S.S. C. Gordon Fullerton performed so well. Just as its namesake would have expected,” Orbital officials wrote in a Twitter statement Feb. 12. “‘Gordo’ would be proud!”
NASA currently has contracts with Orbital and Hawthorne, Calif.-based Space Exploration Technologies Corp. for commercial resupply missions to the station using unmanned spacecraft. SpaceX has a $1.6 billion deal with NASA for 12 cargo missions using its Falcon 9 rockets and Dragon space capsules. Two of those missions have flown so far, with the third slated to launch Feb. 22 from Cape Canaveral Air Force Station, Fla.
