IENAI SPACE: Pioneering the Future of Space Propulsion with ATHENA™ Thrusters

In the vast expanse of space exploration, propulsion technology stands as a critical frontier, and Madrid Space is proud to be a key collaborator in the groundbreaking ATHENA™ project. Having already secured two flights for the technology demonstration in orbit, scheduled for the end of 2024, we find ourselves on the cusp of a new era in space propulsion.

Dr. Daniel Pérez Grande, CEO & Co-founder of IENAI SPACE, expressed his enthusiasm for the project, emphasizing the challenges inherent in developing cutting-edge propulsion technology. "Everyone knows that 'space is hard,' but we like to say that 'propulsion is harder,'" he remarked. The ATHENA™ project represents a monumental achievement, as it involves developing a new propulsion technology entirely from scratch. Despite the challenges, the team at IENAI SPACE is confident that ATHENA™ thrusters will distinguish themselves in the market for their exceptional performance and customization capabilities.

The momentum generated by the latest technical achievements is undeniable, as Daniel highlighted the interest from various industry players. "We have already been approached by a number of interested parties in the industry," he revealed, underlining the significance of ATHENA™ in the space propulsion landscape.

IENAI SPACE's plans extend beyond the ATHENA™ project, as they envision a comprehensive portfolio of electric propulsion solutions for small satellites in the coming years. The ATHENA™ NANO, a 0.5U system, will kickstart this portfolio, catering to cubesats (3U-27U) with direct integration for most commercial cubesat buses and small microsats up to 50kg. Subsequent releases include a larger "MICRO" version and a smaller "PICO" thruster designed for satellites under 3kg, including pico-satellites.

What sets IENAI SPACE apart is its commitment to addressing a market segment that has been largely overlooked by other propulsion providers—the picosatellite thruster market.

The scalability of electrospray technology and the company's innovative 'building blocks' approach enable a diverse range of solutions within their portfolio. This scalability is a testament to Madrid Space's commitment to providing propulsion solutions that are not only cutting-edge but also adaptable to the unique needs of different satellite classes.

As we eagerly await the scheduled flights for the ATHENA™ technology demonstration, Madrid Space stands as a proud collaborator in the thermal and mechanical disciplines, contributing to the future of in-space mobility. IENAI SPACE's end-to-end ecosystem of products, from hardware based on electrospray technology to advanced software, positions them as pioneers in addressing the complete value chain for propulsion and mobility in the realm of small satellites.

From Madrid Space, we have supported the ATHENA™ project up to its PDR stage, contributing in the thermo-mechanical design and analysis of the thruster. We ensured that it’s able to withstand several mechanical loads during the launch phase so that it performs properly once deployed in orbit.

In closing, Madrid Space celebrates its role in the ATHENA™ project, heralding a new chapter in space exploration—one where innovation, dedication, and collaboration propel us toward unprecedented possibilities in the vastness of the cosmos.
