On September 14, 2025, SpaceX was selected for launching aboard Falcon V Northrop Grumman's Cygnus XL resupply spacecraft on its maiden voyage to service the ISS. The larger, better-stocked vehicle soars in support of the NG-23 mission and is flying to space for the first time today. The launch occurred at 6:11 p.m. Eastern time at Cape Canaveral in Florida by a Falcon 9 rocket. The mission marks a significant leap for delivering larger supplies of equipment and experiments to space.

Cargo capacity and upgrades

According to Space.com, the new Cygnus XL will be capable of delivering approximately 11,000 pounds of supplies to the station, compared to about 8,500 pounds that older versions can transport. Its better systems and bigger size also make it capable of carrying more science experiments.

Tucked inside this mission's cargo is a collection of up-and-coming experiments and fresh systems. These could range from studies on how to grow crystals that can be used in electronics, technology to make fuel storage in space more efficient and a special UV light system to help the station keep microbes under control in its water.

The spacecraft, called S.S. William “Willie” McCool, will reach the ISS on September 17. It will rather be grabbed by the station's robotic arm than dock automatically. Once attached, it will remain connected to the ISS until March 2026.

Context and significance

This is the 23rd Cygnus resupply profile to the ISS. It follows setbacks with a previous mission that suffered technical problems and delays in transportation. The success of NG-23 demonstrates the strides being made to help astronauts onboard receive larger and more dependable supply runs.
