The global space propulsion market is expected to continue expanding, yet genuine interstellar travel still feels more like theory than reality. Standard rocketry has taken us to the Moon and Mars, but these remain incremental steps. Reaching the stars will require a complete paradigm shift.
A growing number of researchers believe the answer isn't bigger chemical rockets, but a return to foundational physics - a search that often leads to the once-classified corners of Cold War aerospace. That's the perspective presented in the Engineering Infinity: Earth's First Interstellar Blueprint, which suggests that parts of this conceptual framework may have been outlined decades ago and later obscured behind the Iron Curtain.
