Human Factors in Long-Duration Spaceflight

Mission to Mars is a very dangerous journey. The crew can look forward to the 6 month flight time, 1 year occupation, and 6 months trip. Meanwhile, the challenges of many human factors become complicated and there is even the possibility of ruining the whole task. In this article, we identify the human factor challenges faced by the crew, explain why they are so dangerous, and finally identify ways to mitigate them. The first challenge in long-term space flight appeared almost immediately after the launch, and pulled the gravity of the earth into the microgravity environment.

In addition to biomedical problems related to human space flight, there are many psychological and social problems, especially regarding long-term missions to the space station and distant destinations. In the universe it is in an extremely isolated environment. Mission planners need to consider the number of crew members and composition issues from different countries in different cultures, especially when the crews are mixed. If interpersonal conflict is avoided and effective teamwork is achieved

We still do not understand all the effects of long-term space flight. "Five years ago, NASA Human Research Program's John Charles said," Our sight has changed suddenly, I have been flying for three months, "The list no longer exists." Charles He revealed that he said that moving intracranial pressure rises when all liquids are moved up with zero G. Please take a foresight on the track slowly. "

I do not know much about the impact of long-term space flight. Frequently responded questions include whether some drugs lose their effectiveness in less time than the return time of Mars and whether they can regain muscle mass of Martian gravity as the astronauts do on the planet I include something. Dr. Chris Lanehart, a professor at George Washington University School of Medicine and a faculty member of the School's Space Policy Research Institute, says, Those rehabilitation teams do not exist on Mars. So what's next? "When they try to stand up they faint, so we can not allow anyone to lie on the ship's floor," Lehnhardt said.
