Consequently, the industry is aggressively pursuing alternatives that bypass these fundamental constraints, focusing on high specific impulse and novel propellantless concepts. Advanced Concepts and the Physics Frontier.
Advancing Physics Frontier Concepts in Propulsion
Nuclear Thermal and Electric: Tapping into Terrestrial Power Looking further ahead, nuclear energy offers a solution to the power limitations that constrain current electric propulsion. Within the next two decades, the way humanity moves through the solar system is poised to transform, driven by the urgent need for faster, cleaner, and more efficient travel.
This process delivers a specific impulse significantly higher than the best chemical engines, roughly doubling the efficiency for crewed Mars missions and drastically reducing transit times. Nuclear thermal propulsion (NTP) heats a propellant, such as hydrogen, using a nuclear reactor before expelling it through a nozzle.
