Chairman of the Board
Don Whitney brings operational perspective and strategic oversight to Green Launch as Chairman of the Board. His background as an Air Force pilot and environmental consultant supports informed decision-making around mission planning, execution, and responsible technology development. That combination is especially valuable for specialized services such as high-altitude UV and radiation exposure testing, where operational discipline and environmental awareness both matter. Don helps guide the company's broader direction as it advances sustainable alternatives to conventional launch methods and expands access to near-space testing opportunities. His experience strengthens Green Launch's ability to serve aerospace, defense, and scientific customers that need dependable leadership, practical planning, and a long-term vision for innovative testing and launch solutions.
Yes. UV intensity generally increases with altitude because there is less atmosphere available to absorb and scatter incoming solar radiation. That makes high-altitude testing valuable for evaluating coatings, polymers, sensors, electronics housings, and other payload components that may experience stronger UV exposure than they would at ground level. Testing in near-space conditions can reveal degradation patterns that lab simulations may miss.
