CAPE CANAVERAL, Fla. — In conditions reminiscent of American hero John Glenn’s Friendship 7 flight in February 1962, Orbital ATK’s OA-7 “S.S. John Glenn” Cygnus cargo ship, launching atop a United Launch Alliance (ULA) Atlas V rocket, soared toward orbit to resupply the International Space Station.
Liftoff took place at 11:11 a.m. EDT (15:11 GMT) April 18, 2017, from Space Launch Complex 41. Once in orbit, Cygnus began its four-day trek to the space station. It is expected to arrive at the outpost on the morning of April 22. Cygnus is carrying with it some 7,500 pounds (3,400 kilograms) of crew supplies, cargo, and experiments for the Expedition 51 crew.
The uncrewed cargo freighter was named after the American legend, who became the first American to orbit Earth in the early 1960s. Glenn’s flight, which launched atop a Mercury-Atlas rocket, lasted almost five hours before splashing down in the North Atlantic Ocean.
The S.S. John Glenn, however, will stay attached to the ISS for about three months, re-entering Earth’s atmosphere in July 2017.
