Voyager Technologies on Monday said it has acquired ExoTerra Resource in a deal that gives it capabilities in compact electric propulsion systems used to maneuver satellites in orbit.

Terms of the deal were not disclosed. ExoTerra has about 200 employees.

ExoTerra designs and manufactures Hall-effect thrusters and related components, and solar electric propulsion modules. The company supplied 21 propulsion modules to York Space System for its Tranche 1 Transport Layer satellites that were launched in September for the Space Development Agency. ExoTerra is also on contract to supply propulsion modules to York for the Tranche 2 Transport Layer satellites.

ExoTerra also has contract with commercial customers and NASA. The company’s Halo Hall-effect thrusters were successfully demonstrated in 2023 aboard the Defense Advanced Research Projects Agency’s Blackjack ACES spacecraft.

Voyager has existing products such as power processing units and power systems that support electric propulsion for spacecraft.

Voyager said the acquisition further positions it for opportunities with the Trump administration’s Golden Dome homeland missile defense effort.

“We’re amplifying our collective mission capability with ExoTerra, accelerating delivery across defense and commercial markets,” Dylan Taylor, Voyager chairman and CEO, said in a statement. “As freedom of maneuver becomes central to space control and deterrence, it’s imperative that reliable propulsion systems are built, tested and qualified right here in the United States.”

Voyager and ExoTerra are both based in the Denver area.

Voyager Technologies went public earlier this year with plans to increase its capabilities through mergers and acquisitions. Last month, the company acquired proprietary technology in optical communications from BridgeComm.
