Why the future of space exploration might belong to miniature rocket engines

Scott Manley explores the engineering behind the smallest rocket thrusters. Discover how miniaturizing propulsion systems can drastically reduce launch costs while maintaining the capabilities typically associated with full-sized spacecraft.

While massive engines often dominate the conversation, small rocket designs offer a compelling alternative for modern spaceflight. The feasibility of these tiny engines is largely determined by the specific engine cycle employed during operation.

By enabling the development of smaller spacecraft, these compact thrusters allow for mission profiles that were previously restricted to larger, more expensive vehicles. This shift in scale is a critical factor in making space access more efficient and affordable.
