Northrop Grumman's Last Antares Rocket Launch: Shift to American-Made Engines & SpaceX Partnership

Welcome to our latest video, where we delve into the exciting world of space exploration and technology. In this video, we're discussing the recent developments at Northrop Grumman, a leading player in the aerospace industry.

The focal point of our discussion is the last launch of Northrop Grumman's current Antares rocket from Virginia, a historic event that signals significant changes within the company. The Antares rocket, on the Northrop Grumman-19 mission, carried a whopping 8,200 pounds of science experiments and supplies to the International Space Station (ISS).

However, this launch represents the end of an era, as it was the final use of the Russian-made RD-181 engines on the rocket's first stage. This change has been necessitated due to a federal law requiring the shift towards United States-based engines and supply chain issues related to the war in Ukraine. 

In response to this, Northrop Grumman announced a strategic partnership with Firefly Aerospace in 2022, aiming to create a new version of the Antares rocket. But with this new version not anticipated before 2025, the company has arranged for its Cygnus spacecraft to be launched on its next set of missions via SpaceX Falcon nine rockets from Florida, beginning as early as December. 

In the coming years, Northrop Grumman has planned at least two more resupply launches with SpaceX for 2024, and potentially more through 2025. This is a result of Northrop Grumman's acquisition of Orbital ATK in 2018, which included NASA’s Commercial Resupply Services contract, shared with SpaceX. This partnership allows each company to send up their cargo spacecraft twice a year, providing United States-based resupply arrivals for the astronauts on board about every three months.

The Cygnus spacecraft, while designed to burn up on reentry into Earth’s atmosphere after its mission on the ISS is complete, has the capacity to boost the station’s orbital altitude. This unique capability will be further tested and potentially utilized in future missions. 

The shift towards American-made engines was a necessary move for Northrop Grumman due to rocket engine issues. The upcoming Antares 330 will use seven of Firefly’s Miranda engines and switch to Firefly for the construction of the Antares first-stage tank.
