Space travel has had its significant share of achievements and challenges. The challenges present new ideas to prevent major problems like the Apollo 13 disaster that almost claimed the lives of three astronauts in space. However, the challenge has currently shifted from machines and space equipment modification to human health. According to several studies conducted by different researchers, traveling through space can have severe consequences on the spacemen’s body, which include impaired vision and physical conformation of the eye due to microgravity. Previous research concluded that space travel alters the genetic makeup of the astronauts hence affecting the next generation. Nevertheless, further research conducted displayed that space travel affects the brain too.
According to Larry Karma’s research, a radiologist, microgravity is a significant effect that distorts the brain resulting in enlargement of brain cells and an increase in the level of brain fluid in mind. Additionally, he further conducted research that involved eleven astronauts launching into space. Larry took MRI readings before the launch and after returning to Earth. The results answered the theory and completed the research since the scans reveal brain swellings and increase in brain fluid due to microgravity.
Researchers stated that various methods could explain the blisters in the brain. However, Larry noted that the lack of gravity presented a more robust explanation since blood circulation moves to the head without gravity, a phenomenon that can only be seen when upside down on Earth. Therefore, researchers have placed different innovation into test while on Earth to mimic the conditions in space.
The first medical innovation is the Bio-Monitor developed by Montreal’s Technologies. Astronauts and functions wear the Bio-Monitor by monitoring the health condition of the crew member by analyzing their blood pressure and heart rate. The data is afterward transmitted to Earth where medical staff can monitor the health status of all the crew. David Saint-Jacques addressed the press and the children in Canada Aviation Museum that microgravity presents a significant challenge for astronauts; hence all crew members invest at least two hours exercising to keep the blood flowing evenly in their body system.
On the other hand, researchers have also developed a way to turn the spacemen for a minimum of two hours while they are sleeping. The method of rotating the team is also aimed to evenly distribute the blood throughout the body system, therefore, minimizing the effect of microgravity. The health and safety of the crew members is NASA’s top priority; hence consistent innovation is aimed at improving astronaut’s life in space.
