These include radiation, as locations beyond Earth's protective magnetosphere are exposed to greater levels of solar and cosmic rays. There's also the need for self-sufficiency since lunar or Martian bases are too far to rely on regular resupply missions like the International Space Station (ISS). Last, there's the issue of low gravity, which is especially pressing for long-term missions and habitats beyond...
