On April 18, 2017 at 15:11 UTC the "Cygnus” privately owned U.S. unmanned supply spacecraft was launched from Cape Canaveral launch site of US Air Force. The launch was performed by United Launch Alliance supported by the 45th Space Wing of US Air Force. The "Cygnus” (CRS OA--7 “John Glenn”) unmanned supply spacecraft, built by U.S. space firm Orbital Sciences Corp., was orbited by the “Atlas-5” rocket-carrier on its cargo resupply mission to the International Space Station. CRS means Commercial Resupply Services. The "Cygnus” (CRS OA-7) is the 7th successful flight of the Orbital ATK uncrewed resupply spacecraft Cygnus. The “Cygnus” spacecraft for this mission was named John Glenn in honor of astronaut and senator John Glenn, the first US astronaut to orbit the Earth on “Mercury-6” and the oldest to go to space on STS-95.
