In the early hours of Saturday, Northrop Grumman flew to the international space station and launched an Antal rocket from the east coast of Virginia.
The rocket launched a Swan supply ship into orbit with three other rockets.
7 tons of equipment and supplies were prepared for the laboratory building.

The spacecraft is equipped with 2,255 pounds of scientific equipment, 64 pounds of space walking equipment, 2,183 pounds of space station hardware, 253 pounds of computer equipment and 2,605 pounds of crew supplies, including fresh fruits and ice cream.
