An uncrewed Northrop Grumman-built spacecraft in orbit experienced an issue with its main engine on Tuesday while attempting to reach the International Space Station to deliver scientific supplies, NASA said,

The Cygnus XL spacecraft looks a lot like Northrop's previous missions to the station. It has a service module manufactured at the company's factory in Northern Virginia. This segment of the spacecraft provides power, propulsion, and other necessities to keep Cygnus operating in orbit.
