  1. Perchlorates are not the biggest concern on Mars. The biggest is the lack of enough nitrogen in the atmosphere. If you have for example a green house module with 100 % oxygene, then a fire can be a very big problem. If you add nitrogene the danger will decrease a lot. So having nitrogen is important. But here comes the problem. When you do EVAs, you will loose nitrogen over time and when the nitrogen came from Earth, the loss won't be compensated. In consequence, they definitely need a solution to get nitrogene from mars stones.

  2. Part 2 of 6 This way, the majority of the resulting fission products have such a short half-life that this amount decays into stable elements within about 400 years.

  3. Part 1 of 6 The solution is to build new reactors that are able to fission uranium and transuranium nuclides the old reactors can't fission.

  4. Part 5 and 6 of 6 The longer the half-life, the lower the activity and therefore the less harmful they are.

  5. Part 3 of 6 The small, palpable remainder of long-lived fission products are not transuranic elements and are therefore harmless both chemically and biologically.

  6. Part 4 of 6 Their half-life is so long that they are completely unproblematic.
