Nuclear-powered rover.
According to news on November 24, Beijing time, Mars is an extremely cold place with an average surface temperature of minus 82 degrees Fahrenheit (minus 63.33 degrees Celsius). Fortunately, however, the helium carried by NASA's Mars Science Laboratory (MSL), which is scheduled to launch on the 26th, will ensure that it will not be frozen.
The new Mars is as big as a small car and it will be the largest and most advanced machine ever landed on another planet. Unlike NASA’s previous mission of selecting solar panels, the Mars Science Laboratory will use nuclear power to make more of its production when traveling on the surface of Mars.钚 (Don't worry, it's not a nuclear weapon 钚 238) It generates heat through nuclear decay, warms the lab's electronics, and ensures that it can output data even at night. Unlike previous missions, this Mars rover will be able to shuttle in areas without sunlight, so it can also explore more extensive areas.
Instead of being powered by a nuclear reactor, the car uses cesium 238 to generate a lot of heat and emit dark red light in the dark. This extra heat will be well utilized. It will generate approximately 110 watts of current through the thermoelectric lead crucible, which generates current when a temperature gradient exists. If necessary, this power will allow the Mars Science Lab to operate for several years, but its current mission is only intended to last for 23 months. In order to eliminate any concerns, the Idaho National Laboratory, which is responsible for assembling nuclear batteries, has multi-layered its nuclear fuel and has conducted extensive tests to ensure safety. They pointed out that NASA has also verified the reliability of nuclear power generators through 26 missions over the past 50 years. (xiaowen)
