00:00In addition to the immediate dangers, there are also long-term challenges such as managing radioactive waste, which remains active
00:08for decades or even thousands of years.
00:11Disposal in space, such as launching it into the sun, is technically possible but ethically and legally controversial.
00:19But technically possible does not automatically mean easy.
00:23On the contrary, it's anything but easy to set a course for the sun.
00:27In addition, such propulsion systems require complex launch permits, since countries like the USA and Russia have strict regulations for
00:36transporting fissile material.
00:38The erosion of engine components, the extreme temperatures and the lack of heat dissipation in the vacuum of space, just
00:45as Werner Engel aptly described it using the analogy of a thermos,
00:49could shorten the lifespan of the systems if no innovative cooling technologies are developed.
