Aliena

Aliena is a Singaporean propulsion technology firm specialising in the design and manufacture of electric plasma engines for the small satellite market. Positioned as a Tier 2 or 3 supplier within the NewSpace value chain, the company focuses on miniaturising Hall-effect thruster technology to enable low-altitude operations and orbital maintenance for microsatellites and nanosatellites. Their hardware is designed to provide high fuel efficiency and precise station-keeping for platforms that previously lacked active propulsion. The organisation has successfully demonstrated its technology in orbit, notably through the integration of its engines on the NuX-1 and OrbAstro satellite platforms. Their customer base primarily consists of commercial constellation operators and research institutions seeking to extend mission life or perform complex orbital manoeuvres. They maintain strategic collaborations with the Nanyang Technological University and have engaged in technology verification missions through international launch providers to validate performance in the space environment. Potential buyers should verify the specific Total Impulse and Thrust-to-Power ratios of the hardware against their mission profile, as performance varies significantly between noble gas and alternative propellant configurations. It is also necessary to confirm the flight heritage status of specific sub-components and the compatibility of the Power Processing Unit with the satellite's existing bus architecture. Technical assessments should include a review of the thruster's thermal management requirements during prolonged firing cycles.
