In a move that puts them in contention against SpaceX’s Starship, Chinese researchers have successfully built a prototype nuclear propulsion engine designed for missions to Mars. This development represents a major advance in space propulsion technology and underlines China’s growing ambitions in space exploration.

The prototype, which has been in development for several years, aims to dramatically reduce travel time to Mars, potentially revolutionizing interplanetary travel, according to a report in the South China Morning Post. According to those responsible for the project, “this engine will allow humans to reach the Red Planet in a much shorter time compared to conventional chemical rockets.”

Chinese authorities have expressed enthusiasm for the project, highlighting its importance in achieving China’s long-term space exploration goals. The successful development of this nuclear propulsion engine not only marks a milestone for China but also lays the foundation for a new era in the global space race.

Benefits of nuclear-powered space travel

Nuclear-powered space travel offers several benefits over traditional chemical rocket propulsion, including:

Extended Mission Duration: Nuclear power can provide a continuous source of energy, allowing longer missions in space. This is particularly beneficial for deep space exploration, where sunlight may not be sufficient for solar power systems.

Increased efficiency: Nuclear propulsion is significantly more efficient than chemical propulsion. This efficiency translates into faster travel times and the ability to carry more payload with the same amount of fuel, making it ideal for missions beyond Earth orbit.


Reduced travel time: With greater thrust and efficiency, nuclear-powered spacecraft can reduce the time it takes to travel between planets. This is crucial for manned missions to Mars and beyond, where shorter travel times could reduce the risk of exposure to cosmic radiation and the effects of microgravity on the human body.

Improved power supply: Nuclear power can generate electricity for spacecraft systems and scientific instruments for long periods. This reliable power supply is essential for deep space probes and habitats on other planets, where solar power may be insufficient.

Feasibility of more ambitious missions: The increased payload capacity and longer mission duration made possible by nuclear power open the door to more ambitious space exploration missions, including manned outposts on other planets, asteroid mining, and exploration of the outer planets. and its moons.

Long-term profitability: Although initial development and deployment costs may be high, nuclear-powered spacecraft could become more cost-effective in the long term due to their improved capabilities and potential for reuse across multiple missions.
