Microgravity experienced in space can affect the human body. Muscles and bones, for instance, become weaker without gravity to make the work hard.
Astronauts who work at the International Space Station need to engage in activities that could mitigate the effects of weightless. They currently exercise up to 2.5 hours per day and maintain a balanced diet to stay healthy.
Scientists, however, think there are more ways to help keep astronauts healthy and one of these could be the use of artificial gravity in longer-term space missions.
To see if this could potentially work, the European Space Agency and NASA are funding a study that will investigate how artificial gravity may help astronauts stay healthy in space.To read more, click here.
