Member News 2022 Sperry Award Winner Honored for Advancing In-Space Additive Manufacturing
Lawrence Sperry Award Recognition
The Lawrence Sperry Award recognizes a notable contribution made by a young person, age 35 or under, to the advancement of aeronautics or astronautics. AIAA Associate Fellow Michael Snyder was recognized: “For outstanding and notable contributions to advance in-space additive manufacturing to ensure safer, sustainable spaceflight missions and manufacturing industrial products to benefit Earth.” As noted in his award nomination, “Snyder’s contributions to the industry in the areas of spaceflight technology are significant and have had a notable impact on the trajectory of space exploration. NASA, DARPA, NRO and other agencies have benefited from his expertise to inform various space manufacturing programs. His technical expertise combined with his passion for the advancement of space exploration and his commitment to bridging the gap for the next generation of engineers and aerospace professionals” are what made him an ideal candidate for the Lawrence Sperry Award.
Driven by a Fascination with Space Exploration
Snyder honestly cannot remember a time when he wasn’t interested in aerospace. He loved anything and everything about space exploration, particularly human exploration. “I enjoyed just watching Earth views from shuttle missions that would loop on NASA TV and all the programming they built around space exploration,” commented Snyder. “My immediate family did a great job in nurturing my interests, including having extreme amounts of patience with me after my many ad hoc discovery projects that involved taking appliances apart and attempting to put them back together after I thought I figured out how they worked.” He added, “I was also taken to the library frequently and enjoyed reading nonfiction subjects ranging from astronomy to shipwrecks … I was fueled to dedicate [my] future in the endeavor to expand the capabilities of spaceflight and enable people to live and work in space permanently.”
Snyder knew from as young as second or third grade that he wanted to study aerospace engineering, and he noted, his “home state of Ohio has a great aerospace infrastructure, so I had a few good in-state university choices.” He attended what he considered and still considers to be the best—Ohio State University.
Developing the Skills to Start His Own Company
During his time at Ohio State, Snyder took advantage of the aerospace-related clubs on campus, “sometimes to the detriment of my classwork.” “[I] participated in the aircraft and rocket design teams and had the opportunity to lead them in my junior and senior years. I founded the Electronic Controls Club on campus to facilitate the development of some guidance systems for the rocket team. I also was involved and eventually led the campus AIAA student branch.” He noted that these extracurricular clubs were what developed his management skills, adding, “Those skills vastly improved with the help of the clubs’ advisors, mainly Dr. Jack McNamara.” Snyder is convinced his early management of engineers would have been a much harder experience “without those experiences and tutelage.”
An internship opportunity with an aircraft engine simulation company helped inspire the later application of his Made In Space internship experiences and provided Snyder first-hand insights on the do’s and don’ts of those opportunities.
He credits his graduate advisor, Dr. M. J. Benzakein, for introducing him “to the experience of developing payloads for the ISS with a project he handed over” to complete, “resulting in the on-orbit investigation of the synthesis of nanocrystalline ceria through varying gravitational fields. … That project gave me the incredible experience of designing, building, and qualifying hardware that would operate on the ISS.”
Snyder noted that many people have influenced him in his work over the years. He remarked, “I was always inspired by the folks in mission control and engineers enabling space exploration to take place in my adolescence. I connected to the Apollo folks the most; this was probably due to the available information at the time. Chris Kraft, Tom Kelly, and fellow Ohio native Gene Kranz were all inspirations for me, and I can’t tell you how many times I read their books growing up.”
He added that at college, he had “fantastic mentors. Anita Gale and the late Dr. Eric Rice took me under their wing[s] when it came to AIAA technical activities and really made me feel welcome and allowed me to contribute. The late Dr. Gerald Gregorek at Ohio State really educated me on proper design cycles and alternative ways to view problems both in class as well in the design teams. Mike Johnson educated me greatly in all topics related to payloads, including showing me the most effective ways to present data necessary for qualification. The late Allan McDonald always took my phone calls and mentored me on his views on appropriate safety cultures, especially when the company started to scale up. I think the most influential person during my professional career has been Dr. John Grunsfeld. He brings a perspective that is leaps and bounds beyond any other single source. His guidance has been invaluable with building and running larger programs.”
When asked about the value of AIAA membership, Snyder said that his participation in the student branch beginning as a freshman led him “to access the technical activities of the … national group. I love learning. I loved going to conferences to hear about new work and concepts while presenting on my own, and I love being around some like-minded folks who had a passion for technical development and innovation.” He became a member of the Space Settlement Technical Committee in 2009, while still an undergraduate. He took on the positions of secretary, then co-chair, and finally chair in 2017. He noted, “The bulk [more than 20] of my technical publications have been through AIAA, which started while I was still an undergraduate student.”
Made In Space
Having started his first company providing “mainly consulting services with an eye toward space” as an undergraduate, his work “greatly expanded during graduate school after teaming up with the other co-founders of Made In Space.” The company’s mission was to bring manufacturing and industry to space and create a future where humans are enabled to live and work in space by eliminating the reliance on Earth resupply and spares.
Under Snyder’s technical leadership, Made In Space went on to produce and operate the first additive manufacturing hardware in space, build and operate the first commercial manufacturing hardware for use in space, produce the first optical fiber in space, and became the first company to commercialize space-enabled materials.
Snyder remarked on the untraditional journey that the business has taken, “The phrase ‘Iterate early and iterate often’ applies to both design and business alike. The path we’ve been on has taken many routes that were not predictable at the beginning. … we chose to be agile, to meet customers’ needs while still maintaining objectives toward the end goal: long-term habitation and space-enabled technologies.”
He added, “we set out to do things that never have been done before and there are learning opportunities that make the approach better after modification. We did not take on investment at the beginning of the company so we could maintain that agility and be responsive toward ever-changing demands. We were very fortunate to have a lot of people believe in us, especially early on at NASA Marshall Space Flight Center. They also had a vision that was [well aligned] with our own to bring manufacturing to space. My career has taken twists and turns that took me places that I could not imagine at the beginning or even later on. That’s really part of the excitement. I cannot wait to experience what is to come.”
Looking to the Future
After Made in Space was acquired by Redwire Space in 2020, Snyder became chief technology officer. The company has now launched over 35 payloads and pieces of hardware on 20 missions, including the upgraded International Space Station solar arrays. When asked what he thinks he’ll be working on in the future, Snyder responded, “I look forward to the changing landscape and the new challenges that will present themselves. I do hope that in the decades to come, more space-enabled products are investigated and monetized for use back here on the ground. We’ve been successful on a couple of materials that we’ve tried out, but there are hundreds more that should be looked at. It truly is in its infancy as an industry. I also hope that in situ resource utilization (ISRU) becomes commonplace. The only way sustainable exploration and habitation can occur is living off the land. I think the ISRU technologies developed for space will benefit conditions here on Earth in the long term. We need to be more efficient with how we use materials and energy and what better place to develop those technologies than in space, where it is an absolute necessity, all the time.”
AIAA Foundation Making an Impact: AIAA, Estes Industries, and NSTA Launch New Aerospace Education Initiative: Exploration Generation
AIAA, Estes Industries, and the National Science Teaching Association (NSTA) have joined together to inspire the next generation of scientists and engineers through a new, multi-year initiative that will bring research-based aerospace education to thousands of classrooms nationwide. Exploration Generation (ExGen) will provide K-12 educators with free lesson plans and curriculum storylines to help guide students as they explore various concepts in aerospace, engineering, and rocketry. High-quality professional learning experiences will also be developed to support teachers’ use of the ExGen instructional materials.
To help educators provide a more collaborative, student-centered learning environment where ideas are accessible and engaging for all students, each lesson plan, called NSTA Daily Dos, and the curriculum storylines, called NSTA Units, are grounded in sensemaking. Through this approach, students actively engage in a learning experience to make sense of phenomena in a way that aligns with their natural curiosity. In May, ExGen will unveil its first three Daily Dos developed for the middle school level. The NSTA Unit, designed for grades 6-8, will be available in October. ExGen will expand with additional resources for elementary and high school educators next year. Professional learning for educators will begin this fall with additional programs available in the future.
To ensure this program is widely accessible to as many students as possible, Estes will match the AIAA contribution to the program in the first year of launch through in-kind donations to participating schools and continue in all subsequent years.
In addition, Estes will manage a grant program to provide eligible Title 1 schools with funding to purchase the supplies needed to facilitate these lessons in the classroom. Details on how to apply will be announced later this year.

Obituary AIAA Fellow Green Died in March
Dr. John E. Green, who was responsible for the development of aerodynamics capability at the Royal Aircraft Establishment (RAE) at a critical time for UK aviation and, latterly, explored global aviation’s interaction with the environment, died in mid-March.
Green studied engineering at Cambridge University, graduating in 1959. Initially working for the de Havilland Engine company, he returned to Cambridge in 1961 to research the interaction of shock waves and a turbulent boundary layer, gaining his Ph.D. in 1966.
Joining the Aerodynamics Department at the RAE in 1964, he worked on aerofoil design methods. His most notable contribution was “Green’s lag entrainment” method for turbulent boundary layer development. He was made Head of the Wind Tunnels Division (Bedford) in 1971, then Head of Propulsion Division, Head of the Noise Division, and finally Head of the Aerodynamics Department in 1978. This period was notable because the RAE was supporting the Concorde flight tests prior to its introduction into service in 1976, while also contributing to the Tornado combat aircraft program.
Green was appointed Director, Project Time and Cost Analysis for the Procurement Executive, Ministry of Defence and in 1984, was posted to the British Embassy in Washington, DC, as the Minister-Counsellor and Deputy Head of British Defence Staff, returning to the UK in 1985 as RAE Deputy Director (Aircraft). His final role was Chief Executive of the Aircraft Research Association, before retiring in 1995.
