What happens when you use a SpaceX Falcon 9 rocket to launch Northrop Grumman’s Cygnus supply ship? A record-setting resupply mission to the International Space Station.

The first flight of Northrop’s upgraded Cygnus spacecraft, called Cygnus XL, is on its way to the international research lab after launching Sunday evening from Cape Canaveral Space Force Station, Florida. This mission, known as NG-23, is set to arrive at the ISS early Wednesday with 10,827 pounds (4,911 kilograms) of cargo to sustain the lab and its seven-person crew.
