Northrop Grumman's Cygnus Spacecraft Expands its Horizons
Spacecraft Operated by Northrop Grumman: A Decade of Supplying Science and Cargo to the International Space Station
The Cygnus spacecraft, developed by Orbital Sciences Corporation (now Northrop Grumman), has been a vital component of NASA's Commercial Resupply Services (CRS) program since 2013. Over the past decade, this versatile spacecraft has delivered a wide array of scientific payloads and experiments to the International Space Station (ISS).
The Cygnus spacecraft consists of a Pressurized Cargo Module (PCM) and a Service Module (SM). The PCM, built by Thales Alenia Space in Italy, is designed to be disposable, while the SM provides power, propulsion, and guidance for the spacecraft.
Northrop Grumman is currently involved in cargo logistics services for various space missions, including support for the ISS under NASA's Commercial Resupply Service Phase 2 (CRS-2) contracts. The most recent activity included the departure of Cygnus NG-21 from the ISS on March 28, 2025.
In collaboration with Firefly Aerospace, Northrop Grumman is developing a new Medium Launch Vehicle (MLV) to replace the Antares rocket for Cygnus missions. The Antares rocket has undergone an upgrade from Antares 110 to Antares 230, featuring a first stage powered by two Russian-built RD-181 engines. However, the MLV is designed to provide increased performance and flexibility for Cygnus missions and other commercial and government payloads.
The MLV will utilize a first stage powered by seven Miranda engines and a second stage featuring a single Vira engine, both developed by Firefly Aerospace. This vehicle's 5-meter payload fairing will accommodate a variety of payloads, and its ability to launch from multiple sites, including Wallops Island, Virginia, will provide flexibility for mission planners.
The increased payload capacity of the MLV will enable Cygnus to transport even more cargo and scientific experiments to the ISS. Moreover, the Cygnus spacecraft is expected to provide cargo logistics services to commercial space stations, such as Starlab, which is in development under a NASA Space Act Agreement. This role is crucial for maintaining supplies and equipment needed for the operation of these stations.
While specific plans for deep space exploration missions involving Cygnus are not detailed, Northrop Grumman's involvement in commercial space infrastructure development suggests potential future applications in deep space missions, leveraging experience and technology developed for commercial space stations.
Northrop Grumman has proposed using a modified version of Cygnus as a building block for their own commercial space station concept, known as the Habitation and Logistics Outpost (HALO). The development of the MLV is well underway, with the first launch expected in 2025. The MLV is intended to serve a wide range of customers, including commercial satellite operators, government agencies, and international partners.
Overall, Northrop Grumman's Cygnus spacecraft continues to play a vital role in supporting existing space infrastructure while contributing to the development of new capabilities for future commercial and deep space missions.
