If you need to do more research on the universe, the spacecraft needs a long distance to explore the outer space. Obviously, the current engine driving the spacecraft is still unable to meet the demand for space travel, and even it is not satisfied within our solar system. In addition, the spacecraft is also faced with a problem that the manipulation of sensors and related equipment is too dependent on solar energy. So nuclear energy plays a decisive role here.
The farther the spacecraft is from the Sun, the less energy it can receive, and the worse its work efficiency and functionality. Researchers are currently testing a small model engine that can provide kinetic energy for long-distance space travel. This engine is based on the 19th-century Stirling engine.
The Stirling engine propels the piston through hot compressed air. Scientists in the idea of ​​this engine should use 50 pounds of nuclear uranium batteries to generate heat, carrying about 8 can produce 500W Stirling engine. Scientists at the NASA Glenn Research Center and Los Alamos National Laboratory are now testing a small model engine using this design.
This model uses a nuclear power scheme and a Stirling engine that produces 24W of energy. According to scientists, the deepest space probe currently requires 600-700W of energy. It is also worth mentioning that this test is the first nuclear reactor system test conducted by the United States since 1965 to drive spacecraft. Scientists said that nuclear energy is very important for space exploration of spacecraft. For example, a spacecraft travels to Mars. Sunlight is very weak at this time. Spacecraft have enough solar energy receivers to expand the size of a football field to get enough energy to transmit data. Back to Earth, nuclear energy can balance this issue.
