Building a hypersonic pathway to orbit with Mark Bigham
Mark Bigham, Vice President of Defense Programs at Longshot Space Technologies Corporation, joined SpaceNews host David Ariosto for the latest episode of the Space Minds podcast to outline the company’s new hypersonic launch concept. The conversation, recorded for the weekly audio‑visual series that publishes new episodes each Thursday, focused on a hardware‑centric approach intended to propel payloads to orbit at hypersonic velocities. Bigham described how the method could shift launch frequency from the current several‑times‑per‑week cadence toward a potential several‑hundred‑launches‑per‑day regime, fundamentally altering the cost structure of orbital cargo delivery.
Longshot Space Technologies, a startup dedicated to hypersonic technology development, is engineering a system that accelerates mass to speeds exceeding Mach 5 before transitioning to the exo‑atmospheric phase of flight. The proposed architecture leverages a combination of aerodynamic acceleration and propulsion stages to achieve orbital insertion without relying on traditional multi‑stage rockets. Bigham indicated that the design targets a dramatic increase in launch throughput while reducing per‑kilogram launch costs, a metric that has traditionally limited the economics of frequent cargo missions. The discussion also highlighted the potential for the hypersonic pathway to support defense logistics, given the company’s focus on defense programs, and to integrate with existing launch infrastructure by delivering payloads to a standard low‑Earth‑orbit altitude.
The hypersonic launch concept presented by Longshot aligns with broader industry efforts to boost launch cadence and lower cost, trends that have driven recent investments in reusable launch vehicles and small‑sat launch services. If realized, the ability to conduct hundreds of launches per day could reshape supply‑chain dynamics for both commercial satellite operators and government payload customers, offering a scalable alternative to current launch providers. The Space Minds episode therefore situates Longshot’s technology within the ongoing pursuit of high‑frequency, cost‑effective access to space, underscoring the strategic importance of hypersonic propulsion in future orbital logistics.
