"Northrop Grumman's Antares Rocket: Final Flight Prep and Live Viewing Guide"

Northrop Grumman is preparing for the final flight of the Antares rocket with Russian and Ukrainian components, as a Cygnus cargo spacecraft is set to launch to the International Space Station. The spacecraft will carry nearly 3,750 kilograms of cargo, including experiments, hardware, and crew supplies. This launch will be the last of the current version of the rocket, Antares 230+, as Northrop Grumman is partnering with Firefly Aerospace to develop a new version, Antares 330, with domestically manufactured components. The new rocket will have increased payload performance and is expected to launch in the summer of 2025.
