NASA and Northrop Grumman have postponed the arrival of the Cygnus XL cargo ship at the International Space Station (ISS) after encountering propulsion issues. The new cargo spacecraft, which launched aboard a SpaceX Falcon 9 rocket, was designed to carry a record supply load, but thruster problems have impacted its scheduled rendezvous. The teams are currently assessing the situation, focusing on the engine burn plan necessary for the Cygnus XL to reach the ISS. This mission marks the debut of the upgraded Cygnus XL, which can transport 30% more cargo compared to its predecessors.
