NASA has been planning for a long time to send the first manned mission to Mars. However, having humans travel such a long distance in space can have a huge impact on their bodies, and it’s important to know what changes they will undergo. Therefore, before making any preparations for the mission, they are going to perform a series of studies on the effects of space travel on humans.
Not many astronauts have been in space for long periods of time
It’s extremely important to know what happens to the human body while traveling through space for a long period of time. Therefore, before sending the manned spacecraft on its journey to Mars, NASA should find out what measures it should take to make sure this trip is safe for the astronauts.
The best subjects to look at to see how space affects the human body are the astronauts aboard the ISS. NASA is already keeping them under close observation, but there are some significant differences between them and those astronauts who are to visit Mars. One visit to the ISS usually lasts for about six months, while only the journey to Mars should take about three years.
Space travel can have a great impact on the human body
This means that the effect of space travel might be different if the journey lasts longer. In this case, the scientists need to know how this effect is different, and what to do to control it. The only astronauts who have been in space for a longer period of time have still been there for less than a year. Therefore, NASA should start sending more astronauts on longer trips to space.
At the moment, the space agency is waiting to receive proposals for research, which should last for about seven years. The fields of study are diverse, and contain seven different domains. NASA has already identified the potential dangers coming from space travel, including radiation, lack of gravity, or confinement, and wants to see what long-term impact these have.
