On August 4, 2024, Northrop Grumman's Cygnus spacecraft was successfully launched aboard a SpaceX Falcon 9 rocket from Cape Canaveral, Florida, carrying nearly 8,200 pounds of supplies to the International Space Station (ISS).

This mission, designated NG-21, is part of NASA's Commercial Resupply Service-2 contract and aims to deliver essential equipment, science experiments, and supplies to the ISS.

Shortly after liftoff, the Cygnus spacecraft encountered complications, missing a planned engine burn; however, NASA confirmed that the spacecraft remains at a safe altitude and can be redirected.

Northrop Grumman engineers are currently developing a new burn and trajectory plan to ensure the spacecraft can still achieve its docking time of 3:10 a.m. EDT on August 6.

The Cygnus spacecraft is expected to dock with the ISS approximately 40 hours after launch, with astronaut Matthew Dominick set to capture it using the station's robotic arm.

The resupply mission will support various research experiments, including studies on liquid and gas flow in life support systems and the production of high-quality blood and immune stem cells.

Among the experiments onboard are those focusing on the effects of microgravity on biological and physical processes, including plant growth and water purification.

In total, the Cygnus is carrying nearly 8,200 pounds of supplies, which include food and scientific equipment necessary for the ISS crew.

Ryan Tintner, Northrop Grumman's vice president of civil space systems, emphasized the company's commitment to supporting NASA and sustaining life and science research on the ISS.

This launch marks the 21st supply flight of a Cygnus freighter to the ISS, continuing Northrop Grumman's strong track record in resupply missions.

The Cygnus spacecraft for this mission is named S.S. Francis R. 'Dick' Scobee, honoring the NASA astronaut who commanded the Challenger shuttle in 1986.
