Northrop Grumman's Cygnus XL Successfully Delivers Supplies to ISS After Software Issue
The Cygnus XL cargo spacecraft docked with the International Space Station, delivering over 11,000 pounds of supplies following a software-related engine shutdown.
Northrop Grumman's Cygnus XL cargo spacecraft successfully docked with the International Space Station (ISS) on Thursday, delivering over 11,000 pounds (4,990 kilograms) of supplies and scientific equipment to the seven-member crew. The docking occurred at 7:24 a.m. EDT (11:24 UTC), with NASA astronaut Jonny Kim using the station's robotic arm to capture the spacecraft.
The mission experienced a one-day delay due to a premature engine shutdown during the spacecraft's approach. Engineers identified the cause as a "conservative safeguard" in the onboard software settings.
This flight marked the debut of the Cygnus XL variant, featuring an extended cargo module that increases its capacity by 33%. The delivered supplies include food, scientific experiments, and equipment for the station's systems.
The Cygnus XL is scheduled to remain attached to the ISS until March 2026, after which it will depart and reenter Earth's atmosphere for disposal.
Northrop Grumman named this spacecraft the S.S. Willie McCool, honoring the late Columbia shuttle pilot who perished in 2003.
