Proposing to dispose of waste in space raises concerns about the risks of rocket failures potentially spreading hazardous materials back to Earth, although this argument is often deemed invalid due to the safety of existing space technology. Space-based radioisotope thermoelectric generators (RTGs) have successfully contained radioactive materials under extreme conditions, suggesting that similar methods could be applied to waste disposal. However, the high costs associated with space disposal and the current effectiveness of terrestrial storage make this approach unnecessary. Radioactive waste is not as significant a problem as often portrayed; it is managed safely, with much of it being recoverable material. Overall, the discussion emphasizes that while space disposal is theoretically feasible, it is impractical and unwarranted given existing solutions.
