MIT researchers, with NASA backing, are advancing nuclear thermal propulsion to drastically reduce Mars travel time by heating propellant with nuclear energy; Hampson models a full engine’s thermodynamics and neutronics, addresses startup/shutdown cooling challenges, and leverages the MIT Reactor for fuel testing as NASA eyes crewed Mars missions in the 2030s.
Engineers at Ohio State University and the University of Alabama are developing a centrifugal nuclear thermal rocket using molten uranium, which could potentially halve the travel time to Mars from nearly two years to about 420 days, though significant engineering challenges remain.
A study on nuclear thermal propulsion suggests it could significantly reduce travel time to Mars and the Moon by providing high thrust and efficiency, with safety measures ensuring minimal radiation exposure and long-term feasibility for heavy spacecraft, though it faces technical and safety challenges for future development.
Researchers are making progress on the centrifugal nuclear thermal rocket (CNTR), a new type of nuclear propulsion that could nearly double the specific impulse of traditional systems by using liquid uranium fuel in a centrifuge, though significant engineering challenges remain, particularly in uranium containment and vaporization management.
Engineers at the U.S. Energy Department's Idaho National Laboratory are developing nuclear thermal propulsion technology to cut travel time to Mars in half, potentially making human missions to the Red Planet more feasible. This effort could lead to a new space race, with the U.S. and China both aiming for crewed missions to Mars.
NASA is working on developing nuclear thermal propulsion technology to cut the travel time to Mars in half, with a goal of reaching the planet by 2040. Engineers at the Idaho National Laboratory are leading a nationwide team of scientists to enhance the capabilities of this technology. The longer journey to Mars poses logistical challenges and risks for astronauts, including exposure to microgravity and radiation. China is also working on its own nuclear propulsion project and has plans for a manned mission to Mars in the mid-2030s.
Lockheed Martin is advocating for its Mars Base Camp (MBC) concept, which involves building a Mars-orbiting station as a base for crewed expeditions and excursions to the Martian moons. The MBC program is expected to take about a decade to reach fruition and would allow for telerobotic exploration of the Martian surface and sample return. The company supports long-duration conjunction class missions, which provide more science and exploration time. The propulsion system of choice is nuclear thermal propulsion, which enables shorter trajectories for human missions. Lockheed Martin's MBC is not contingent on the success of NASA's Artemis program and aims to reduce risk and demonstrate capabilities. The challenge lies in garnering political support due to the cost and long timelines associated with Mars missions.
