Earth To Mars In 100 Days? The Power Of Nuclear Rockets

TL;DR

Nuclear rockets can shorten space travel times, while fusion drives offer energy-efficient propulsion for interstellar missions.

Transcript

The Solar System is a really big place, and it takes forever to travel from world to world with traditional chemical rockets. But one technique, developed back in the 1960s might provide a way to dramatically shorten our travel times: nuclear rockets. Of course, launching a rocket powered by radioactive material has its own risks as well. Should we... Read More
