CAPE CANAVERAL, Fla. (AP) — A newly launched supply ship has encountered engine troubles that are hindering its journey to the International Space Station (ISS). Northrop Grumman’s capsule, which was launched into orbit on Sunday from Florida aboard a SpaceX rocket, is now facing significant challenges just two days after its launch.

During its ascent, the capsule’s main engine experienced a premature shutdown while attempting to boost its orbit. This unexpected failure has caused a delay in the scheduled docking, which was planned for Wednesday. The Cygnus capsule was set to deliver over 11,000 pounds (5,000 kilograms) of cargo, including essential supplies such as food and scientific experiments for the seven astronauts currently residing on the ISS.

NASA has announced that all operations are currently on hold as flight controllers evaluate alternate plans to address the situation. This mission marks the debut of Northrop Grumman’s latest model, the Cygnus XL, designed to carry a significantly larger payload compared to its predecessors.

The cargo aboard the Cygnus capsule is critical, containing not only food and science experiments but also crucial spare parts for the ISS's toilet and other vital systems. Northrop Grumman is one of NASA’s two primary cargo suppliers for the ISS, with SpaceX being the other. In addition to these American suppliers, Russia also plays a key role in resupplying the ISS, with the latest shipment arriving over the weekend.

As the situation develops, Northrop Grumman and NASA are working diligently to resolve the engine issue and establish a new plan for the Cygnus capsule. The successful delivery of this cargo is essential for the ongoing operations and scientific research conducted aboard the International Space Station.
