New commercial supply ship reaches ISS
Print Edition
NASA’s newest delivery service pulled up at the International Space Station yesterday after a week’s delay, bringing more than a half-ton of meals and special treats to the astronauts who assisted in the high-flying feat.
With the smooth linkup, Orbital Sciences Corp became only the second company to accomplish such a far-flung shipment.
The space station astronauts used their ship’s huge hulking robot arm to grab the Cygnus capsule, as the two vessels flew 418 kilometers above the Indian Ocean.
“Everybody is just so excited,” Mission Control radioed. Ground teams described the achievement as “epic” and “superb.”
Orbital Sciences launched the Cygnus capsule on this test flight from Virginia on September 18. It was supposed to reach the ISS on September 22, but got held up by inaccurate navigation data. A software patch fixed everything. Then the Cygnus had to wait for a Russian spacecraft bringing three new astronauts in midweek.
The successful arrival means the Virginia-based company can begin making good on a US$1.9 billion contract with NASA for a series of Cygnus deliveries. The next one could fly by Christmas.
Applause could be heard in Mission Control once Italian astronaut Luca Parmitano grabbed hold of Cygnus with the space station’s mechanical arm.
“Good capture. That’s a long time coming,” Mission Control radioed.
“Smiles all around,” added Orbital Sciences in a tweet.
Yesterday’s successful operation culminated years of effort for Orbital Sciences, which was hired by NASA along with the California-based Space Exploration Technologies Corp to keep the space station well stocked in this post-shuttle era.
SpaceX has been launching its supply ships, called Dragon, for more than a year. It’s also working on a possible manned capsule that would ferry US astronauts to the space station, rather than having them hitch rides on Russian rockets.
Unlike the SpaceX Dragon that can return items to Earth, the Cygnus is designed to burn up upon descent. Once unloaded of its 590 kilograms worth of food, clothes and other items, Cygnus will be filled with trash and cut loose toward the end of October. That’s how the Russian, European and Japanese supply ships end up as well: self-destructing garbage cans.
The latest delivery included student experiments and, as expected, chocolate for the six-person crew.
