CAPE CANAVERAL, Fla. — An Orbital ATK load boat firm for a International Space Station is staid for liftoff Tuesday (April 18) aboard a United Launch Alliance (ULA) Atlas V rocket.
ULA’s 71st Atlas V rocket is scheduled for launch during 11:11 a.m. EDT (1511 GMT) from Cape Canaveral Air Force Station in Florida. You can watch a liftoff live in a 360-degree perspective here, pleasantness of NASA TV.
“We are looking brazen to a good launch tomorrow and stability a record of 100 percent goal success,” Vern Thorp, United Launch Alliance’s (ULA) blurb missions module manager, told reporters during a lecture Monday (April 17). [Watch: How Orbital ATK’s Cygnus Will Fly on Atlas V Rocket]
The rocket will be carrying Orbital ATK’s seventh Cygnus load boat underneath a $3.1 billion, 10-flight agreement with NASA by 2018.
Orbital ATK’s possess midsize launch vehicle, Antares, returned to moody final October following an collision in 2014, though this time a association and NASA opted for a hired float aboard ULA’s beefier Atlas V, that can lift some-more load into orbit.
Orbital ATK formerly bought dual Atlas V rides to a space hire to fill a opening while Antares was retrofitted with new engines.
The Cygnus load ship, named after Mercury wanderer John Glenn, a initial American to circuit Earth, will be carrying about 7,635 lbs. (3,463 kilograms) of food, reserve and scholarship experiments to a station. That is about 660 lbs. (300 kg) some-more than what could be packaged aboard for launch on an Antares, pronounced Frank Culbertson, a former wanderer and boss of Orbital ATK’s Space Systems Group.
One examination on house is a worldly new hothouse that will be evaluated as a approach to grow food for astronauts during long-duration stays in space. The Advanced Plant Habitat, that is about a distance of a mini refrigerator, includes some-more than 180 sensors to magnitude temperature, oxygen calm and dampness levels.
Unlike a station’s existent plant-growth chamber, known as Veggie, a modernized hothouse requires comparatively tiny organisation time to set adult and operate, NASA officials said.
Initially, a cover will be used to origin and grow exam samples of wheat and Arabidopsis, a tiny flowering plant. The initial scholarship experiments are designed for November.
Samples for several biomedical studies also will float aboard a Cygnus, including an review to diminution a side effects of cancer-fighting chemotherapy drugs by incorporating antibodies that aim usually a infirm cells.
The plug also is carrying 38 shoebox-size satellites called cubesats, 4 of that will sojourn on house a booster and be deployed after it departs a hire in July.
If Cygnus is launched as designed on Tuesday, it will dawdle in circuit until Saturday to concede time for a Russian Soyuz spacecraft, slated to lift off on Thursday with dual new hire crewmembers, to wharf during a outpost.
Forecasters on Monday likely a 90 percent possibility a continue would be suitable for launch on Tuesday. The OA-7 goal has been on reason for a month due to a technical emanate with a rocket’s first-stage hydraulics.
