IT Home, Aug. 24, Jim Bridenstine, NASA Administrator, said recently that the United States will develop the next generation of nuclear thermal propulsion technology (nuclear thermal propulsion), which is expected to reduce the travel time by half. Spacecraft using this power system can reach Mars as soon as 3-4 months.
The new generation of nuclear thermal propulsion spacecraft transforms liquid hydrogen into ionized hydrogen plasma by heating the reactor, and generates propulsion through the nozzle, thus achieving the goal of reaching Mars in three to four months. This approach is about twice as fast as conventional chemical power, and astronauts will receive less radiation due to shorter travel times.
From the 1950s to the 1970s, the United States developed a nuclear-powered engine to enhance the rockets carrying capacity, but in 1972, the United States stopped the program. Until the end of March, when Vice President Burns proposed to return to the moon in 2024, Congress approved NASAs $125 million budget for nuclear thermal propulsion technology. NASA plans to land on Mars in 2033.
