After a three-day trip to the International Space Station (ISS), Orbital ATK's Cygnus resupply vehicle finally reached Earth's orbiting laboratory on May 24, NASA announced.
Launched on May 21 from the Wallops Flight Facility in Virginia atop an Orbital ATK Antares rocket, the Cygnus spacecraft carrying more than 3 tons of cargo was intercepted by the space station's robotic Canadarm2 on Thursday morning, at 5:26 a.m. EDT (09:26 GMT).
Operated by NASA astronaut Scott Tingle, flight engineer for Expedition 55, the robotic arm secured the unmanned Cygnus cargo capsule to the Earth-facing port of the station's Unity module three hours later, Space.com reports.

The Cygnus spacecraft brought the ISS astronauts a nearly 7,400-pound (3,350 kilograms) delivery of science gear, food, clothes, and other "goodies" meant to make their long stay in space as comfortable as possible.
"There's always goodies on board," said Kirk Shireman, NASA's space station program manager.
"We try to fly something that each crewmember likes. So, I'm sure there's something for them to look forward to," Shireman told journalists after the Cygnus launch.
Among the scientific equipment delivered by the Cygnus spacecraft on Orbital ATK's ninth supply run for NASA is the space agency's Cold Atom Lab (CAL), a revolutionary quantum physics experiment that will turn the ISS into the coldest place in the known universe.
