One of the most compelling arguments to me is the radiation in space and how we could not have survived it.
Scientists are investigating the possible threat posed to astronauts by inhaling lunar dust.
A study suggests the smallest particles in lunar dust might be toxic, if comparisons with dust inhalation cases on Earth apply.
Teams hope to carry out experiments on mice to determine whether this is the case or not.
During Project Apollo, astronauts traveled through the Van Allen belts on both the outbound and return trips to the moon. The crews spent only limited time in transit in the region, and consequently the radiation exposure was limited. The Apollo 14 crew recorded the highest Van Allen belt exposures during their February 1971 mission, but the crew's short-term exposure was still within acceptable levels. Future manned missions beyond earth orbit must also transit the Van Allen belts, but these missions will be shielded and hardened for much longer-duration exposure to cosmic rays and solar wind.
The Earth actually has two radiation belts of different origins. The inner belt, the one discovered by Van Allen's Geiger counter, occupies a compact region above the equator (see drawing, which also includes the trajectories of two space probes) and is a by-product of cosmic radiation. It is populated by protons of energies in the 10-100 Mev range, which readily penetrate spacecraft and which can, on prolonged exposure, damage instruments and be a hazard to astronauts. Both manned and unmanned spaceflights tend to stay out of this region.
It would be easy to shrug off the Wikipedia propaganda portal if not for the fact the online “encyclopedia” gets preferential treatment for the mega-search engine, Google.
The best material to block high-energy radiation is hydrogen, explains Frank Cucinotta, astronaut radiation health officer and manager for Space Radiation Health Research at the Johnson Space Center. "But you can't make a shield out of pure hydrogen, so we look for materials than have a high hydrogen content, like polyethylene, a common plastic, which is 1 carbon and 2 hydrogens."
Astronauts would still need to cope with the 70 percent of the radiation that's getting through the shields. So Cucinotta and his colleagues are looking at other solutions, like medication.
Like I said, this is not my field and I just wanted to put the hypothesis out there
