Cape Canaveral, Florida: A United Launch Alliance Atlas 5 rocket lifted off from Florida on Tuesday, propelling a cargo capsule filled with supplies and science experiments toward the International Space Station.
The 19-story booster soared off its seaside launch pad at Cape Canaveral Air Force Station at 11:11am EDT/1511 GMT. Nasa broadcast an unprecedented 360-degree view of the launch via YouTube, in a debut of new video technology.
“A beautiful launch," said Vern Thorp, a United Launch Alliance manager. “It looks like we nailed the orbit once again."
Atop the rocket was an Orbital ATK Cygnus capsule loaded with more than 7,600 pounds (3,450 kg) of food, supplies and experiments for the station, a $100 billion research lab flying about 250 miles (400 km) above Earth.
The Cygnus is scheduled to reach the station, a project of 15 nations, on Saturday. Its cargo includes a greenhouse that the US National Aeronautics and Space Administration is testing to grow food for astronauts on long missions.
The capsule also carries 38 shoebox-sized satellites and a high school student’s science project that will test how telomeres, which are structures at the ends of chromosomes, are affected by microgravity.
As people age, telomeres tend to shorten. Preliminary results from a study of astronaut twins, however, show the telomeres of former astronaut Scott Kelly, who spent nearly a year aboard the station in 2015 and 2016, actually lengthened during his time in orbit, the opposite of what was expected.
“The researchers are kind of scratching their heads at that," space station associate scientist Tara Ruttley said during a press conference on Monday.
Tuesday’s successful launch followed a month’s delay while United Launch Alliance, a partnership of Lockheed Martin and Boeing Co, resolved a technical issue with the rocket’s hydraulic system.
The Cygnus cargo ship is the seventh of 10 planned missions through 2018 under Orbital’s space station resupply contract with Nasa, worth up to $3.1 billion.
Nasa also hired privately owned SpaceX to fly cargo to the station. In 2019, privately owned Sierra Nevada Corp will begin operating a third US supply line to the station.
Russia and Japan also fly cargo ships to the station.
By the time the Cygnus arrives, the station will have two new crew members.
Nasa astronaut Jack Fischer and Russian cosmonaut Fyodor Yurchikhin are scheduled for launch from the Baikonur Cosmodrome in Kazakhstan at 3:13 am EDT/0713 GMT on Thursday, docking at the station about six hours later. Reuters
