Chief Technical Officer
Dr. John W. Hunter serves as Chief Technical Officer at Green Launch and brings deep expertise in high-velocity propulsion systems. A physicist by training, he previously led the SHARP project at Lawrence Livermore National Laboratory, giving him rare hands-on experience with extreme-speed launch concepts and advanced aerospace testing. At Green Launch, he helps guide the technical direction behind light-gas propulsion, hypersonic vehicle testing, and scalable launch system development. His background supports the company's work in pushing payloads to high Mach velocities while maintaining a practical engineering focus on repeatability, safety, and mission performance. Dr. Hunter's leadership is central to Green Launch's effort to create a sustainable and cost-effective alternative to conventional rocket launches.
Strategic Outreach
Eric Robinson leads Strategic Outreach for Green Launch and contributes a blend of systems science, entrepreneurship, and aerospace application insight. His experience with fluid delivery systems is especially relevant to launch architectures that depend on precise gas handling, controlled propulsion inputs, and reliable mission coordination. At Green Launch, he helps connect the company's technical capabilities with the needs of aerospace, defense, and research organizations seeking practical alternatives to traditional launch methods. He plays an important role in communicating how light-gas propulsion can support sub-orbital missions, atmospheric sampling, and future orbital delivery. Robinson's cross-disciplinary perspective helps Green Launch align engineering innovation with customer requirements, partnership development, and long-term market adoption.
Chairman of the Board
Don Whitney serves as Chairman of the Board at Green Launch, bringing valuable operational and strategic perspective to the company. His background as an Air Force pilot contributes practical insight into mission planning, performance demands, and disciplined execution in aerospace environments. He also adds experience as an environmental consultant, which aligns well with Green Launch's emphasis on cleaner propulsion and more sustainable launch methods. Whitney supports the company's broader vision of making space access more efficient, cost-effective, and environmentally responsible. His leadership helps balance technical ambition with operational readiness, stakeholder confidence, and long-range planning as Green Launch advances from successful proving-ground tests toward expanded sub-orbital and orbital capabilities.
Ground systems are used to prepare, accelerate, control, and support payload launches before flight. In Green Launch's case, they include launch tubes, gas manifolds, controls, and related infrastructure used for hypersonic testing, sub-orbital payload delivery, atmospheric sampling, and future orbital missions. These systems help create repeatable launch conditions, gather performance data, and reduce risk before full-scale operational deployment.
