Northrop Grumman, shifting to space coast for future space station missions. The last launch of Northrop Grumman's current Antares rocket from Virginia took place recently. Marking a shift in the firm's resupply missions to the International Space Station towards the space coast. Over 8,200 pounds of science experiments and supplies were carried to the International Space Station on the Northrop Grumman 19 mission. However, this was the final use of the Russian made R-181 engines on the rocket's first stage due to a federal law requiring the shift towards United States-based engines and supply chain issues related to the war in Ukraine. Consequently, Northrop Grumman announced a partnership with Firefly Aerospace in 2022 to create a new version of the Antares rocket. However, this won't be available until at least 2025. So Northrop Grumman has arranged for its signal spacecraft to be launched on its next set of missions via SpaceX Hulk and 9 rockets from Florida, starting as early as December. Northrop Grumman has at least two more resupply launches with SpaceX planned for 2024 and potentially more through 2025. The company's acquisition of Orbital Act in 2018 included NASA's commercial resupply services contract, which it shares with SpaceX, meaning each company sends up their cargo spacecraft twice a year. This provides United States-based resupply arrivals for the astronaut onboard about every three months. The signal spacecraft burns up on re-entering to Earth's atmosphere once its mission on the International Space Station is complete, but it does have the capacity to boost the station's orbital altitude. This capability will be tested further. Northrop Grumman's rocket engine issues necessitated the move towards an American-made solution, and the new Antares 330 will use seven of Firefly's Miranda engines and switch to Firefly for construction of the Antares' first stage tank.
