A spaceship Cygnus Cargo leaves the International Space Station (ISS) today (July 15), about two months after arriving at the supply and scientific equipment for a six-person team in the station [19659003
The unresolved Cygnus Oy-9 satellite, also known as the SSJR Thompson, left the ISS at 8:37 am EDT (12:37 GMT) when astronaut Alexander Gerst and the USSR. NASA astronaut Serena Auñón-Chancellor were used by the European Space Agency using Canadarm 2, 18 m, the robotic arm containing the astronauts controlled inside the ISS [19659004] It will be on the lower Earth orbit for the depot lawfully six small satellites called cuestas, using the Cubuset NanoRacks external Deployer for the next two weeks, after which it will burn in the atmosphere anywhere in the Pacific Ocean, ro aming and falling on the earth .
Raised and powered by Northrop Grumman Innovation Systems (NGIS) – an isolated aerospace engineering company, formerly known as the Orbital ATK – NASOP's Cygnus OA-9 space plane Wallops Flight in Wallops Island, Virginia, May 21. Antares Rocket .
He exploded in the ISS with 7,385 lbs. May 24 (3,350 kilograms) for scientific experiments, food, clothing and hardware for the crew of six of Expedition 55. But the payload of the mission did not not given to the space station – before embarking on his journey to Earth, Cygnus provided a last-party gift: An orbital boost that increased the size of the station .
NGIS Vice President of Advanced Programs, Frank DeMauro, told Space.com that On July 10, Cygnus was docked in the space station's Unity module, the space shuttle used to test the spacecraft to determine if the cargo ship could be used to increase the orbit of the space station. seconds .
As for the size of a small bus, there may be a penalty against Cygnus ISS, which is as big as a football field. But its powerful delta-v engine has put enough emphasis on increasing the space station to about 282 feet (869 meters) . DeMauro said "The burn went very well, as we expected the spacecraft to actually behave ."
DeMauro said " We have a lot of Vigorous spacecraft on the spacecraft, which we use to control the spacecraft, but we have a big engine use … actually to increase our class from where the antirecks are firing us the station was left at the # Orbit, so we paid attention to that and we said that the engine had enough emphasis and was very efficient, and we could use that engine, while we were connected to the station doing the promotion. from the station
. "ISS already has a method to promote its class using the boosters, but now the work of raising all classes by the Russian side of the space station is done." Focus by Russia, the v Russian cargo cargo rover can also promote the orbit of the space station. As early as July 10, Cygnus extended the class of the station, he advanced the US spacecraft to ISS class expansion since the Space Shuttle unloaded in 2011.
DeMauro said "In the interest of NASA to have the capacity of Cyanasus, it may be that we may have the extra capacity of the Russian or backup capability that can already do ".
On average, ISS is in Earth orbit at an altitude of 248 miles (400 kilometers). A small amount of atmospheric drag makes it slow; its height decreases by about 1.2 miles (2 km) per month .
Being able to promote the height of the space station not only prevents the release of space, but the same technique can be used to help clear the ISS of orbital debris, so that the ISS is accompanied by incoming vehicles they can be kept in good condition, eventually messing up the ISS. But to do these things, a new amendment in the Cygnus spacecraft will be needed, DeMaruo said. The cargo ship is currently designed to promote the orbit of the space station only, and the OA-9 is the first Cygnus who fired and succeeded.
SS JR Thompson is the ninth NGIS among 11 cargo resuscitation missions, formerly ATC's orbital launched for NASA under a $ 2.9 billion contract. Another Cygnus, OA-10, will be launched at ISS in November 19659003.
