The United States Space Force is exploring new methods to extend the operational life of aging satellites that are growing short on fuel. The concept centers on attaching compact propulsion modules, described by the department as micro-jets or jetpacks, to orbiting devices to boost their maneuvering capability and longevity. This approach was highlighted in reports from Breaking the Defense and is being studied as a potential way to prolong satellite missions without requiring a full replacement cycle.
Prototype propulsion units were showcased at a recent space technology conference held in Orlando, Florida. The demonstrations showcased compact, boost-capable systems designed to resupply and reorient satellites in orbit, potentially reducing the need to deploy new vehicles as replacements.
Representatives from the Space Force’s leadership emphasize that the fundamental methods used to keep orbiters operational have remained largely unchanged since the early days of near-Earth exploration. They suggest that current practices are increasingly inefficient and may contribute to waste, especially as satellite fleets age and the demand for reliable space assets grows. The emphasis is shifting toward more sustainable, ship-in-place solutions that can extend the useful life of existing space assets.
In addition to augmentation propulsion, other options under consideration include strategic refueling of satellites that are still active but nearing the end of their fuel lives. This would involve delivering propellants to satellites in orbit to restore maneuverability and extend mission timelines, potentially offering a cost-effective alternative to launching new satellites.
Recently, the Space Force’s Space Systems Logistics Command signed a contract with Northrop Grumman to develop and implement a new passive refueling module (PRM). This initiative has been adopted as a standard in the department’s technology development programs, signaling a commitment to more flexible and resilient space logistics. The PRM is envisioned to enable passive resupply capabilities that can be integrated with existing satellite platforms, aiding in lifecycle extension and operational readiness.
There has also been public discussion at the Pentagon about Elon Musk’s SpaceX Starship platform and its potential role in future military operations. While the exact applications and approvals remain under review, industry observers note that commercial launch systems are increasingly intersecting with national security considerations, prompting ongoing dialogue about interoperability, safety, and strategic implications for space-based assets. These conversations reflect a broader trend toward leveraging commercial capabilities to enhance national security objectives in space, balanced with risk management and regulatory oversight.
