The supply of space stations that entered orbit in Virginia on Saturday showed a second line in two days.
Another commercial delivery will take place in two to three weeks.
"What is an outstanding launch," said Joel Montalbano, NASA's space station program manager.
Northrop Grumman fired Antares rockets from Wallops Island before dawn to delight the early birdwatchers on the Atlantic coast. The International Space Station (IAEA) launched its own supply to the International Space Station soon.
US delivery is scheduled to arrive at a laboratory in orbit the day after the Russian shipment. Among the £ 7,400 items in the Cygnus capsule are ice cream for three space station residents and a 3D printer that recycles fresh fruit and old plastic into new parts.
Thanksgiving turkey dinner – of course rehydratable – is already riding on a 250-mile high outpost. The space station is now home to the United States, Germany and Russia.
There is another big incident happening. The space station entered Tuesday's 20th anniversary. The first section started on November 20, 1998 in Kazakhstan.
When Montalbano celebrated the International Space Station for 20 years, "one of the coolest things is that we work together all over the world." Then there is a US commercial effort to stockpile the space station, resuming crew firing at Cape Canaveral. "I've had great success," he said.
This Cygnus (or Swan) was invited to celebrate the legendary astronaut who commanded the first space shuttle flight to the Moon. He was named John Young. He died in January.
It is the first commercial freighter to be named after Northrop Grumman. Northrop Grumman acquired Orbital ATK in June. SpaceX is NASA's other commercial shipper for space agencies. The Dragon Capsule is scheduled to take off in early December.
Experiments arriving through Cygnus observe how the cement solidifies under zero gravity. There are medical, space suits and other equipment to replace items that failed to orbit last month due to Russian rocket failure. The two men on the rocket survived the emergency landing. Three other astronauts will be launched on December 3 in Kazakhstan.
