NG-24 is a planned cargo resupply mission to the International Space Station (ISS) under NASA's Commercial Resupply Services (CRS) contract. Operated by Northrop Grumman and flying aboard a Falcon 9 Block 5 rocket, the flight is scheduled to launch no earlier than April 8, 2026. It is expected to depart from Cape Canaveral Space Launch Complex 40 during a launch window lasting from 8:42 to 9:02am on April 8. ^{[2] [3]}

The spacecraft is named the S.S. Steven R. Nagel . ^[4] Following NG-23, the mission is the second to use the Cygnus XL spacecraft configuration, featuring a pressurized cargo module measuring 7.89 meters (25.9 ft) in length, with a payload capacity of 5,000 kilograms (11,000 lb) and a pressurized cargo volume of 36 cubic metres (1,300 cu ft). ^[5]

It is expected to be the fourth and final Cygnus launch on a Falcon 9, arranged after Northrop Grumman's Antares 230+ was retired in 2023 due to supply chain disruptions stemming from the Russian invasion of Ukraine. ^[6] Cygnus NG-25, slated for late 2026, is planned to be the first Cygnus launch with the newly-developed Antares 330 rocket. ^[7]

Background

Main article: Cygnus (spacecraft)

The Cygnus cargo spacecraft was developed by Orbital Sciences Corporation with partial funding from NASA's Commercial Orbital Transportation Services (COTS) program. It pairs a pressurized cargo module built by Thales Alenia Space—derived from the Multi-Purpose Logistics Module used on the Space Shuttle—with a service module based on Orbital's GEOStar satellite bus.

The first Standard Cygnus flew in 2013, followed by the larger Enhanced Cygnus in 2015. Orbital Sciences became Orbital ATK in 2015 and was acquired by Northrop Grumman in 2018. Since then, Northrop Grumman has continued CRS operations. NG-24 is the twelfth Cygnus mission under the CRS-2 contract. ^[8]

Manifest

NASA reports that the mission includes approximately 11,000 pounds (5,000 kg) of cargo. In a press release, they highlighted several research projects being delivered to the ISS on this mission. These include a new module for the Cold Atom Laboratory, hardware and model organisms for biological research, and a radio receiver for observing the ionosphere. ^[1]

The mission will include bringing ClimCam (Climate Camera) to the ISS, to be attached to the Bartolomeo platform of the Columbus External Payload Facility. Developed by the Kenya Space Agency, the Egyptian Space Agency, and the Uganda national space program, the ClimCam Payload will be used for climate and weather observation in East Africa. ^[9]

Also included on the manifest is LEOPARDSat-1, a 1U CubeSat that will test the effectiveness of thin carbon sheeting to block radiation. It was developed by CubeCats, a student organization at the University of Cincinnati. It will be launched from the Nanoracks CubeSat Deployer on the ISS. ^{[10] [11]}

Mission

The Pressurized Cargo Module (PCM) was manufactured by Thales Alenia Space in Turin, Italy, and assembly of the service module for the NG-24 spacecraft took place at Northrop Grumman's facility in Dulles, Virginia. ^[8] Thales Alenia Space shared that the PCM had left their clean room bound for the Kennedy Space Center on January 30, 2026. ^[12]
