Aliena

Aliena Pte Ltd is a Singaporean space-tech company founded in 2018 and headquartered in Singapore, designing miniaturized electric propulsion systems for small satellites operating in very low Earth orbits (VLEO). The company's flagship MUSIC (Multiple Upsilon Satellite Integrated Cluster) electric propulsion system is a plasma thruster engineered for high thrust-to-power efficiency, enabling small satellites to maintain precise orbits, extend operational lifetimes, and perform accurate maneuvers at altitudes where atmospheric drag is significant.

Aliena's VLEO focus addresses a key emerging market: satellites flying below 450 km altitude offer dramatic improvements in imagery resolution, lower latency for communications, and reduced signal attenuation for Earth observation missions. The MUSIC thruster makes sustainable VLEO operations feasible for small satellite platforms by providing sufficient thrust to overcome atmospheric drag with power budgets compatible with small spacecraft.

Beyond propulsion, Aliena aims to build end-to-end remote sensing services leveraging its VLEO satellite capabilities, creating an integrated business model that combines hardware development with commercial data product generation. The company's Singapore base provides access to a growing regional space ecosystem and international investor network.
