In terms of missions into deep space, there are more than a few technical hurdles that need to be addressed prior to crews traveling to destinations such as the planet Mars. The time spent between worlds holds all sorts of dangers, from the threat caused by the weakening of the body in the microgravity environment, micrometeoroids - as well as the threat posed by radiation.
If one reviews what NASA and other space-related organizations the proposals as to how these agencies will handle the issue of space-borne radiation, is usually via specially-shielded sections of the spacecraft that will be encased with the water that the crew will take with them to their destination. That is except for, A Voyage to the Planets, in the 2004 television production, a manned expedition throughout the solar system is carried out and the crew on board their “Pegasus” spacecraft are protected via a magnetic shield, one that lights up, much like the aurora of Earth.
