Voyage to the Planets and Beyond is a DVD well worth watching if you think about human travel to other planets and what the challenges would be to walk about Venus, Mars, or the moons of Jupiter or Saturn. The production demonstrates the stress of such long duration space flight would most certainly result. In fact, the human factor is quite light as compared to what will confront humans on such voyages in this century. The video is quite educational for high school and college level to understand the solar system and human spaceflight generally. I purchased it and would do so again.
