In-depth knowledge of gas dynamics at hypersonic speeds is required to define the environment and requirements for the design and safe operation of space vehicles, planetary probes, and rockets. Development of physical models and numerical methods has enabled major advancements in our approach to the design of vehicles, and has minimized the needs for extensive flight tests. However, there remain many challenges in our ability to model the hypersonic regime. Transport of mass, momentum, and energy in hypersonic flows in thermo- chemical non-equilibrium requires further development of the physical models and reliable experimental data to guide and validate these models. The complexity of the physics in the hypersonic regime presents unique challenges for measurement techniques and flight tests.
