Entrepreneurship Beyond Earth: Andrew Binder’s Work in Space Innovation
Andrew Binder arrived at Purdue University in 2015 with a lifelong interest in space exploration and an early inclination toward entrepreneurship. A self-described sci-fi enthusiast, Andrew pursued an undergraduate degree in Aeronautical and Astronautical Engineering, drawn to the challenge of working on complex systems that push the boundaries of what’s possible. He always enjoyed creating and building things, a mindset that shaped his career and his return to graduate school.
As an undergraduate, Andrew completed Purdue’s Certificate in Entrepreneurship and Innovation Program. He immersed himself in the university’s entrepreneurial ecosystem, completing every undergraduate entrepreneurship course offered and even taking an idea through Purdue Innovates’ Firestarter program. “These experiences gave structure to something I’d always been drawn to,” Andrew shared. “It helped me understand how ideas turn into real opportunities.”
After graduation, Andrew joined Northrop Grumman, where he worked on building and testing satellites. Around the same time, a science video introducing the concept of momentum-exchange tethers sparked an idea that stayed with him for years. Unlike the video’s sci-fi framing, Andrew realized the concept was technically feasible using today’s physics and technology. While working full-time, he continued developing the idea independently, communicating with Purdue professors who shared his interest.
Andrew eventually returned to Purdue to pursue his PhD and to develop his ideas in greater depth. As part of his research, he and his collaborators discovered that paired tether systems near Earth and the Moon could reliably and repeatably transport payloads back and forth. With minimal recurring fuel costs, this infrastructure enabled these payloads to cycle between Earth and the Moon. This breakthrough has the potential to save tens of millions of dollars per mission by reducing the fuel, mass, and complexity required for space travel. Their work gained national attention, drawing interest from organizations including NASA, the Department of Defense, and the Aerospace Corporation.
To expand his work beyond his own research as a graduate student, Andrew founded SLING, a Purdue student organization focused on designing and testing scaled models of momentum-exchange tether systems. The group, now consisting of about 30 students from across engineering disciplines, has contributed new modeling insights and validation techniques, pushing the boundaries of current understanding while giving students hands-on experience with frontier technology.
As Andrew looks ahead, he is considering multiple career paths – from exploring roles in national research organizations to launching a venture built around his research. Regardless of the path he chooses, he credits the Certificate in Entrepreneurship and Innovation Program with shaping his approach to innovation. “The biggest thing I learned,” he said, “is that great ideas matter, but relationships matter more. Strong connections are what turn ideas into impact.”
