Exploring beyond boundaries with precision and purpose
At Sener, we lead the development of advanced space exploration technologies that enable scientific missions to operate beyond Earth — reliably, autonomously and sustainably. From high-precision space exploration robotics to in orbit operations support, our subsystems are designed for the most demanding planetary, orbital and deep-space environments. We contribute to flagship European and international programmes through robust, mission-critical engineering, expanding the frontiers of what is possible in modern space exploration.
For more than 50 years, we’ve been at the forefront of space exploration engineering, developing technologies that contribute to human knowledge, planetary science and future interplanetary logistics. Every mechanism, subsystem and robotic platform is built for resilience and designed for discovery.
Our 100% in-orbit success rate reflects a long-standing commitment to quality and precision. We are trusted by space agencies worldwide — including ESA, NASA and JAXA — to design and deliver complete subsystems for orbiters, rovers, telescopes and return-capable spacecraft. Our work supports not only deep space missions but also critical on orbit servicing tasks, in orbit testing and satellite platform evolution.
From robotic arms on the ISS to advanced attitude and orbit control systems, we provide intelligent, scalable technologies that respond to mission complexity and operational longevity.
We operate across the full lifecycle of space exploration missions — from early-stage concept and system architecture to integration, qualification, and extended in orbit operations. Our facilities in Spain and Poland are equipped for cleanroom manufacturing, environmental testing, and long-duration simulations that replicate space conditions. We also conduct end-to-end validation for technologies used in on orbit servicing and scientific satellite calibration.
Whether developing mechanisms for telescopes or GNC systems for autonomous vehicles, we combine flight heritage with innovation — integrating AI and automation into next-generation orbital and exploratory platforms.
We contribute to major space exploration missions, including Rosetta, Euclid, JUICE, DART and Artemis, delivering critical technologies for asteroid research, space observatories, planetary defence, and lunar return — supporting science, safety, and deep-space discovery through precision engineering and mission-proven systems
We develop advanced systems for in orbit operations, combining robotics, GNC, and electronics to support deep space missions. With over 50 years of experience and a 100% success rate, we enable agencies worldwide to explore, test, and evolve spacecraft through reliable, scalable space exploration technologies.
