Space Force Selects Northrop Grumman for Revolutionary ‘Elixir’ Satellite Refueling Demonstration
In a groundbreaking move, the Space Force has entrusted Northrop Grumman with a pivotal contract to innovate satellite refueling technology through a new ambitious mission dubbed Elixir. This marks a significant advancement in the quest for enhanced mobility and operational flexibility in space.
Continuing a Legacy of Innovation
In a strategic advancement, Northrop Grumman’s dedication to fostering satellite infrastructure is reinforced by this latest award, which builds on its previous success with the Geosynchronous Auxiliary Support Tanker (GAS-T). This contract, managed by the Space Systems Command, empowers Northrop to implement lessons learned from the GAS-T project, leading to the establishment of a robust refueling capability.
Lauren Smith, Northrop’s program manager for in-space refueling, emphasized the importance of this initiative: “The Elixir program enables us to complete development, build, and launch of our refueling payload, which was at the heart of our GAS-T tanker. We’re excited to continue advancing technologies for refueling,” she commented during a recent interview with Defense News.
Elixir Mission: Overcoming Space Challenges
Smith withheld specific details about the financials or technical intricacies of the Elixir contract but shared critical insights. The Rapid On-Orbit Space Technology Evaluation Ring (ROOSTER-5) is set to carry the payload, which was initially scheduled for a 2027 mission.
The innovative spacecraft designated to receive refueling will be outfitted with Northrop’s Passive Refueling Model—an interface recognized as a preferred standard by the Space Force. Smith explained that Elixir aims to address three crucial technical challenges vital for satellite operations in space:
- Rendezvous and Proximity Operations: Effectively positioning satellites close enough for interaction.
- Docking: Achieving physical contact between two satellites.
- Fuel Transfer: Successfully transferring fuel between spacecraft.
“Performing refueling in space does require a carefully orchestrated dance,” Smith remarked. “We’re excited to demonstrate this capability on orbit. The scale at which this mission is being executed will facilitate a seamless transition to future operational use if the customer opts for it.”
The Need for In-Space Refueling
As tensions in space increase, in-space refueling stands as a critical enabler of mobility—a top priority for the Space Force given the growing capabilities demonstrated by countries like China and Russia. Notably, General Michael Guetlein highlighted several instances of Chinese satellites engaging in what he termed “satellite dogfighting maneuvers” during a defense conference earlier this year.
“Our observations include five different objects in space maneuvering in synchrony,” Guetlein detailed, adding, “They are practicing tactics for on-orbit operations between satellites.”
Looking Ahead: The Future of Satellite Refueling
The Space Force has yet to unveil a comprehensive plan for integrating satellite refueling and servicing within its operational framework. However, Elixir represents just one of several upcoming demonstrations designed to shape future strategic planning.
The 2026 mission involving refueling spacecraft developed by Astroscale U.S. is already on the horizon. Additionally, a collaboration with the Air Force Research Laboratory titled Tetra-5 will witness two satellites docking with refueling vehicles, one from Orbit Fab’s refueling station and the other from Astroscale—all lined up for the same year.
