<p>Over the last decade, the need for hypersonic systems has become a key priority for many government agencies across the world. However, flight-testing opportunities remain limited. Performance of hypersonic platforms is primarily examined through analytical models or ground testing, owing to the high cost and high risk of flight testing. The flight environment at hypersonic speeds is simulated with testing facilities such as wind tunnels, shock tubes, and plasma tunnels; however, limitations with each approach mean the full flight envelope is unable to be fully replicated on ground. Progress is slow as a result. With this renewed focus on hypersonic and suborbital platforms, new commercial flight-testing capabilities are entering the market such as Rocket Lab’s HASTE and DLR MORABA’s VS-50. The HiSST conference posed an opportunity to gather experts in the field to provide an overview of their platforms, to collect the needs and interests of the research and industrial community for their technologies’ demonstration, and to understand blockers for advancing particular concepts.</p>
