summary

This article discusses the shortage of plutonium-238, a radioactive isotope used to power deep-space missions. Plutonium-238 is essential for providing the necessary power to spacecraft that venture far beyond Mars, as solar panels are not viable at such distances. The article explains the history of plutonium-238 production and how the United States' supply has been depleted over the years. It also explores the implications of this shortage on the future of space exploration, highlighting the potential limitations and challenges faced by NASA and other space agencies. The article concludes by discussing the efforts being made to reestablish a reliable supply of plutonium-238 through collaboration between government agencies, research institutions, and private companies.
