The Cygnus XL cargo spacecraft supporting Northrop Grumman’s 23rd Commercial Resupply Services mission is scheduled to depart the International Space Station (ISS) on March 12 after completing its delivery mission.

During its stay at the orbiting laboratory, Cygnus XL delivered more than 11,000 pounds of supplies, scientific experiments, hardware and other cargo for NASA and its international partners.

Flight controllers will command the station’s Canadarm2 robotic arm to separate the spacecraft from the Unity module’s Earth-facing port and maneuver it into position before release. European Space Agency astronaut Sophie Adenot will monitor the Cygnus systems as she leaves the station.

After departure, the spacecraft will remain in orbit briefly before receiving the order to deorbit on March 14. During its re-entry into Earth’s atmosphere, Cygnus will remove several thousand pounds of station debris and burn it harmlessly.

The mission launched in September 2025 aboard a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

This flight also marked the first mission of the upgraded Cygnus XL spacecraft, a larger, more payload-capable version of the solar-powered resupply vehicle designed to support ongoing logistics operations for the International Space Station.
