Cygnus XL’s ISS Rendezvous Delayed After Premature Engine Shutdowns

Mission teams are evaluating alternate burns after the new cargo ship’s main engine cut off early during two orbit‑raising maneuvers.

Overview

  • NASA reported two early shutdowns of Cygnus XL’s main engine during planned orbit‑raising burns on Sept. 16, with all other spacecraft systems performing normally.
  • The planned Sept. 17 capture by the station’s Canadarm2, to be operated by astronaut Jonny Kim, is on hold as a new arrival time is reviewed.
  • SpaceX’s Falcon 9 launched Northrop Grumman’s NG-23 from Cape Canaveral on Sept. 14; the spacecraft separated from the upper stage as planned and deployed its solar arrays.
  • NG-23 is the debut flight of the larger Cygnus XL, featuring a cargo module extended by 1.6 meters and carrying roughly 5,000 kilograms (about 11,000 pounds) of supplies, spares, and research in what outlets described as a record commercial resupply load.
  • The delay unfolds as Northrop Grumman repairs a previously damaged NG-22 cargo module and continues relying on Falcon 9 launches pending the Antares 330 first stage targeted for around 2026.
