NG-23 CARGO MISSION ARRIVES AT ISS, Sept 17, 2025, Earth orbit, 6:35 am ET

If launch of Northrop Grumman’s NG-23 Cygnus spacecraft with cargo for the International Space Station crew is on time on September 14, it will arrive at the ISS on September 17 at 6:35 am ET.

Cygnus berths to the ISS rather than docks, so it is captured by Canadarm2 and then installed onto a docking port.

NASA coverage begins at 5:00 am ET for the 6:35 am ET arrival. Coverage of the installation of Cygnus onto the docking port begins at 8:00 am ET. Watch on NASA+ and Amazon Prime.
