A SpaceX Falcon 9 rocket will launch a Cygnus spacecraft from Northrop Grumman on a resupply mission to the International Space Station. This will be the 22nd launch of a Cygnus spacecraft and the first launch of a Cygnus XL spacecraft, which is capable of carrying 1,250 kg more cargo than the previous version of the Cygnus spacecraft. The spacecraft is named the S.S. William ‘Willie’ C. McCool.
