Engine Trouble Delays Northrop Spacecraft’s Cargo Delivery to ISS

A Northrop Grumman spacecraft designed to deliver cargo to the International Space Station (ISS) has experienced an engine issue, delaying its planned arrival. The Cygnus XL, an upgraded version of Northrop’s cargo craft, encountered the problem during its first flight.

Engine Stops Early During Orbital Manoeuvre

The uncrewed Cygnus XL launched on Sunday aboard a SpaceX rocket from Florida. It carried 11,000 pounds (around 4,990 kilograms) of scientific equipment and supplies for the crew aboard the ISS.

However, NASA reported on Tuesday that the spacecraft’s main engine shut down earlier than expected. The engine was conducting two planned burns to raise the spacecraft’s orbit closer to the space station. Due to the early shutdown, the mission has been delayed. Despite the engine issue, NASA confirmed that all other systems on the craft remain in good condition.

NASA and Northrop Working on New Plan

The Cygnus XL was originally scheduled to dock with the ISS on Wednesday, 17 September. This plan has now been postponed. NASA is currently collaborating with Northrop Grumman to develop an alternative engine burn strategy that will allow the spacecraft to safely reach its destination.

The agency has not disclosed the craft’s current position or shared any backup plans. A new arrival date will be announced once the situation is resolved.

Cygnus XL Joins NASA’s Cargo Fleet

This mission marks the debut of the larger Cygnus XL variant. Northrop’s Cygnus and SpaceX’s Dragon are NASA’s primary cargo spacecraft for ISS resupply missions. Both play a critical role in maintaining the station’s operations by delivering essential supplies and research materials.

NASA’s teams are continuing to monitor the spacecraft as they work toward a successful rendezvous with the ISS.
