The News That Matters about the Nuclear Industry Fukushima Chernobyl Mayak Three Mile Island Atomic Testing Radiation Isotope

Future Nuclear-Powered Spaceships (oh by the way, one crashed to Canada in the past)

Interstellar for Real: Meet the Nuclear-Powered Spaceships of the Future Sputnik news,  22 Apr 18, Spaceships using conventional hydrogen-oxygen fuel will be able to take people to the moon, Mars or Venus. But human exploration of other planets in our solar system, and beyond it, will require the creation of ships harnessing the power of nuclear fission and nuclear fusion, including via the concept of nuclear pulse propulsion.

………Icarus envisions sending multiple probes across multiple solar systems within 15 light years of Earth to carry out detailed studies of stars and planets. Like Daedalus, the project requires helium-3 for fuel, which can be found in ample quantities on Neptune or Jupiter, but which is scarce on Earth. Based on the current pace of technological development, such foreign-planet mining, and hence such a mission, may not be possible until the year 2,300.Ultimately, Anton Pervushin believes that so long as the nuclear test ban treaty remains in force, nuclear pulse propulsion will inevitably remain a theoretical concept. Furthermore, as Pichugina explained, in addition to legal issues, a number of technical questions remain unresolved. These include how to apply fuel to the combustion chamber, how to amortize acceleration, how to protect crews from cosmic radiation, and in general determining the most efficient types of spacecraft.

Still, as Pervushin noted, if humanity wants to escape the bonds of our solar system and send large spacecraft to those close by, nuclear pulse propulsion remains the only realistic option.Postscriptum: Nuclear Fission for Electrical Propulsion

In addition to the ambitious proposals for interstellar nuclear fission and nuclear fusion propulsion, Soviet scientists worked intently from the 1960s to the 1980s on nuclear fission electric power propulsion systems, which transform nuclear thermal energy into electrical energy, which is then used to power conventional electrical propulsion systems.

The Soviet space program pioneered and worked to improve the technology with the Kosmos series of satellites, which, while generally successful, had their reputation somewhat marred following the emergency descent of Kosmos 954 in 1978, which spread radioactive debris over northern Canada.

The Soviets continued to experiment with these technologies well into the late 1980s, and even envisioned the use of nuclear fission-based energy as a realistic means to reach Mars. https://sputniknews.com/science/201804221063803318-nuclear-powered-spaceships-of-the-future/
