Changes in the environment Essay
Changes in the environment
The changes in environment that people in space experience also mean changes in significant cues. For example, there is the absence of a fixed horizon that is expected to reduce the efficiency of a person’s perceptions of shape, distance, location and motion (Man-Systems Integration Standards, 2006). The noise aspect is also considered as a human factor particularly in the design of habitat (Special Issue on the International Workshop on Human Factors in Space, 2000).
One of the critical requirements in space is the ability of people to communicate with each other. There are noise exposure limits that are established because outside Earth, even low levels, especially when it is intermittent noise, can affect the communication system and human performance especially in complex tasks. Noise also causes fatigue, distraction, irritation and aggressiveness which are already under the scope of psychology but nonetheless, far from what are needed by the people in space (Man-Systems Integration Standards, 2006).
The humans must be able to acclimatize themselves to changes in pressure associated with space travel. Because humans are used to atmosphere with 21% oxygen at sea level, equipment and traveling environment are adjusted to maintain an equivalent partial pressure that would sustain life. Pressure values vary from person to person depending on his or her degree of acclimatization to altitude. As a rule, people who are accustomed to higher altitude require less total pressure compared to people who are not accustomed to higher altitude.
The partial pressure for normal people who work in space are usually maintained above 152 mm Hg while those who are not accustomed to such environment must maintain a total pressure above 417 mm Hg (Man-Systems Integration Standards, 2006). Psychology The management of human’s psychological state in space is indeed a part of NASA’s standards. “Human factors research and technology will also ensure that interpersonal interactions are planned maintain a healthy and constructive attitude, thus enhancing productivity and mission success among an international culturally-diverse crew (Man-Systems Integration Standards, 2006).
” This implies an assumption that metal and psychological performance and human interactions could have a very significant role in the success of an exploration. Conclusion With the advent of space age, the human factors research contributes significantly especially to the present knowledge in flight, which involves the participation of humans. Success in space missions would be doubtful without consideration of the human factors to which any mission’s success or failure depends. References Brown, D. L. , DeVilbiss, C. A. , Ercoline, W.
