WASHINGTON — Quantum Space is acquiring propulsion technologies and facilities from Phase Four to support development of its Ranger maneuverable spacecraft.

The company announced Sept. 22 it acquired Phase Four’s multi-mode propulsion technology and its integration and test facility in Southern California. Terms of the deal were not disclosed.

Phase Four’s multi-mode propulsion technology allows a thruster to operate both as a chemical thruster, providing high thrust, and as an electric thruster, offering greater efficiency. Last year, the company said it demonstrated the technology in its Maxwell Block 3 thruster using hydrazine and ASCENT, a nontoxic alternative propellant.
