What UARX Space does
UARX Space, S.L. is a privately held Spanish aerospace company founded in 2020 by Yanina Hallak (CEO) and Andrés Villa (CTO), both Cal Poly San Luis Obispo alumni, that provides in-space transportation and logistics services for small satellites. The company designs, manufactures, and integrates three principal hardware platforms: OSSIE, an orbital transfer vehicle (OTV) capable of transporting up to 400 kg of CubeSats, PocketQubes, and small satellites to custom orbits including lunar transfer trajectories using chemical or electric propulsion; RAMI, a 12U CubeSat deployer with TRL9 flight heritage from the Ariane 6 maiden flight and best-in-class 39 mm protrusion clearance; and the SAU&RON family of separation rings (8", 15", 24") with proprietary actuators and payload capacities from 80 kg to 800 kg. Additional platforms include LUCAS (a lunar orbiter under development, up to 1,000 kg to Moon orbit) and LOLA (a lunar lander for up to 100 kg of surface payloads), positioning the company for expansion into cislunar logistics.
UARX generates revenue through a mix of hardware sales (SAU&RON rings, RAMI deployers), launch and rideshare services booked through OSSIE missions, hosted payload services via a partnership with SpaceLocker, and engineering consulting spanning mission analysis, thermal analysis, GNC, structural analysis, and critical software development. The company sells primarily via direct enterprise sales targeting satellite operators, space agencies, and constellation operators, supplemented by channel partnerships in Latin America (DIY Satellite), and event-driven demand generation at industry forums including IAC, SSSIF, and the DLR Mikrolauncher Competition. Its maiden commercial OSSIE mission is manifested on SpaceX Transporter-18 for 2026 with 12 customers, and the company is integrating Dawn Aerospace's Docking and Fluidic Transfer Port to enable in-orbit servicing capabilities.
The company operates from a 1,200 m² headquarters in Nigrán (Galicia, Spain) with ISO 7 and ISO 8 cleanrooms and capacity to integrate six OTV units simultaneously, plus a secondary office in Mar del Plata, Argentina. It is family-owned, has received partial funding from CDTI (Spanish public R&D entity), and is a member of the ESA Boost! OMEGA consortium with Dawn Aerospace and Spherical Systems. As one of only five to six companies globally developing orbital transfer vehicles, UARX occupies a structurally constrained competitive niche, though it remains pre-commercial on its flagship OTV service and does not publicly disclose revenue.
