Space Force Sets 2027 Flights for Two Commercial Satellite Servicing Demonstrations

The U.S. Space Force will execute two commercial satellite servicing demonstration missions in 2027 to evaluate in-orbit refueling and maneuvering for high-value defense payloads. Col. Scott Carstetter, director of servicing, mobility, and logistics at Space Systems Command, outlined the plans during an industry webinar on Sept. 23, 2026. The demonstrations mark a shift from study to flight for the Space Force's servicing ambitions.

The planned missions represent a transition in how the Department of Defense approaches space domain awareness, mobility, and logistics. Historically, military and intelligence satellites in geosynchronous Earth orbit were treated as single-use, non-serviceable assets, built with finite station-keeping propellant reserves that fixed their operational lifespans regardless of payload health.

Under SSC's Space Mobility and Logistics portfolio, the Space Force is moving toward dynamic space operations, in which orbiting assets can be maneuvered to avoid threats, refueled in flight, or repositioned across orbital planes without exhausting core operational lifespans. By partnering with commercial servicing primes, SSC aims to establish standardized interfaces for fluid transfer, mechanical docking, and orbital relocation across defense constellations. The dual demonstration program will establish operational baselines for commercial service procurement, measure the infrastructure required for routine in-space logistics, and define the economic thresholds where life extension or refueling proves more cost efficient than deploying replacement spacecraft.

The 2027 campaign comprises two distinct mission architectures. The Astroscale U.S. mission will focus on high-altitude propellant transfer in geosynchronous orbit. An Astroscale servicer will rendezvous and dock with a military target satellite in GEO to transfer hydrazine or a specialized green propellant. After the refueling sequence, the servicer will maneuver to a separate commercial fuel depot orbiting in GEO to replenish its own tanks, validating multi-use, repeatable refueling operations in deep space.

The Starfish Space mission will deploy an autonomous servicing vehicle known as the Otter tug to perform proximity operations and mechanical docking. The Otter will conduct rendezvous and proximity operations with multiple national security satellites, docking with client craft to adjust their orbital inclinations and relocate them to new strategic slots before uncoupling to engage subsequent targets. Both missions will rely on standardized docking fixtures and robotic capture interfaces designed to allow third-party vehicles to engage military spacecraft without damaging thermal blankets, solar arrays, or sensitive payload antennas.

Carstetter framed the demonstrations as a way to answer basic procurement questions. "These two commercial servicing missions planned for 2027 will help us answer fundamental questions about how the military buys on-orbit services," he said. "We need to determine how much infrastructure is required to support routine servicing, while establishing the exact operational conditions where refueling or life extension makes better financial and military sense than launching a replacement satellite."

The operational data gathered during the 2027 flights will inform future Space Force acquisition frameworks for permanent in-space servicing, assembly, and manufacturing capabilities across upcoming defense constellations.

Space Systems Command will continue joint integration campaigns with Astroscale U.S. and Starfish Space through late 2026 to qualify launch manifests, finalize rendezvous flight software, and complete safety reviews for the target spacecraft.
