Aliena

What Aliena does

Aliena is a Singapore-based space technology company incorporated in 2018 as a spin-off from Nanyang Technological University (NTU), specialising in electric propulsion systems for small satellites. The company's flagship product, the MUSIC Electric Propulsion System, is a multi-stage Hall-effect thruster available in 1.5U (self-ignition mode) and 4U (hot mode/dual mode) form factors, delivering thrust from 0.1 mN to 3 mN and total impulse up to 15 kNs. A complementary in-house component, the Hydrocat low-current hydrogen hollow cathode, has also been developed and contributed to the AQUAHET consortium that demonstrated the world's first Hall thruster operating on oxygen and hydrogen from water electrolysis. Aliena has accumulated flight heritage through deployments on a 3U nanosatellite (January 2022 via SpaceX Falcon 9) and on OrbAstro's 12U ORB-12 Strider satellite (July 2023), and is contracted to provide a custom MUSIC thruster for Singapore's ELITE remote sensing satellite to be operated at very low Earth orbit (VLEO).

The company generates revenue through multiple streams: off-the-shelf and bespoke hardware sales of MUSIC propulsion systems to satellite operators; component-level sales such as hollow cathodes to technology partners like URA Thrusters; and collaborative R&D services with research institutions under programmes such as the EUREKA GlobalStars initiative. GTM is sales-led, with a dedicated VP Business Development driving direct enterprise outreach across Asia, the UK, and the EU, supplemented by participation in Singapore's Space Access Program and Space Technology Development Programme. Aliena's Jet Propulsion Test Facility (JPTF) in Singapore — the first commercial facility of its kind in the country — supports in-house development, qualification, and lifetime testing, with a planned upgrade to an 8,020 sq ft Advanced JPTF expected by end-2024.

Cumulatively, Aliena has raised over US$9.3 million across a November 2019 seed round (S$1.5M) and an April 2024 US$5.5M Series A led by Wavemaker Partners, with participation from SEEDS Capital (Enterprise Singapore), Cap Vista (DSTA), Paspalis, NTUitive, and prior investor 500 Global. The team of 1-10 includes PhD co-founders Dr. Mark Lim (CEO) and Dr. George-Cristian Potrivitu (CTO), along with VP R&D, VP Business Development, and dedicated space systems engineers. Customers and end markets span telecommunications, Earth observation, and deep-space science missions operated by governments, commercial constellations, and research institutions.

Core offering

Aliena designs, manufactures, and sells electric propulsion systems for small satellites (nanosatellites and microsatellites). Its flagship MUSIC Hall thruster family is offered in 1.5U and 4U form factors with multi-mode operation (self-ignition, hot mode, and dual/fault-tolerant), delivering thrust from micro to milli-Newtons at very low power budgets for missions including VLEO operations, constellation phasing, station keeping, and deorbit. The company also sells proprietary components such as the Hydrocat hollow cathode and develops bespoke/custom propulsion engines for specific mission requirements.

Product overview

Aliena is a Singapore-based space technology company specializing in electric propulsion systems for small satellites. The company offers the MUSIC Electric Propulsion System as its flagship product—a multi-stage Hall thruster available in 1.5U (self-ignition mode) and 4U (hot mode/dual mode) form factors. These propulsion systems enable satellites to operate in very low Earth orbits (VLEO), providing capabilities for orbit servicing, constellation phasing, station keeping, debris removal, and deorbit at end-of-life. Aliena's products are sold globally to satellite operators for telecommunications, Earth observation, and deep-space science missions.
