Mars had long held a special fascination for people – partly because of the likelihood that life might either now exist or in the past have existed on the planet. For over half a century scientists have studied how to get astronauts onto the various areas of Mars. Now, when large, posh spaceship is constructed with speedy propulsion systems to get to the planet Mars in a very short time, a crew will be sent in space exploration. The crew will stay on Mars for three months. The entire crew will participate in surface exploration on Mars. Astronauts in spaceflight and in space tend to have high rates of health complaints.
Stress problems are reported in 50 percent to 70 percent of physical illness (Boston 55). Headaches, nose and chest colds, and digestive problems are common in outer space environments. Instances of anxiety and depression often occur. If NASA sends people to Mars for a long enough period of time, experts must be accounting for their health status. In Thomas Jefferson’s instructions to Meriwether Lewis in 1803, the president of the United States wrote: “ … To your own discretion therefore must be left to the degree of danger you may risk, and the point at which you should decline,
only saying we wish you to err on the side of your safety, and to bring back your party safe even if it be with less information… ”. According to the policy Human Health and Medical Direction for Space Exploration “Thomas Jefferson’s preoccupation with human welfare should continue to inspire and guide future undertakings into the unknown environments, especially space. ” An enormous amount of factual material regarding the behavior, mental health, performance, and interpersonal relationships that define the lives of crew members in flight should be used in the various mission preparation activities.
