Space4 combines UArizona’s moonshot culture with the brightest minds in space surveillance, astrodynamics, machine learning, and data science.

The result? Game-changing capabilities and a workforce that meets the national security demands of the new space economy for you, for Arizona, and for the nation.

Housed within Research, Innovation and Impact, Space4 is a group of researchers with trusted and demonstrated expertise in science and engineering.

Together, we are committed to ensuring responsible, peaceful, and sustainable access to and exploration of all orbital regimes in the Earth-Moon system for future generations.

We love what we do and invite you to engage with Space4.

Space4 and Faculty

We offer three types of seed grants to faculty across all units to support research-related travel, development of white papers, and proposal development.

Space4 and Students

We offer experiential learning opportunities to develop and expand the future workforce in commercial, academic, and governmental space careers.

Space4 and Partners

Beyond campus, we partner with government, industry, and other academic institutions to provide continuing education and interdisciplinary research expertise.


Hear from two of our founders about the challenges and opportunities in the orbital space between Earth and the moon that drove the conception of Space4, and the mission that keeps us going.

Hear from Our Students

Training undergraduate and graduate students on state-of-the-art methods and techniques in space domain awareness is key to the Space4 mission. But don't just take our word for it. Meet some students who are an integral part of our work.
