Discussion threads can be closed at any time at our discretion. 17th Annual Photo Contest Finalists Announced. To counteract these problems, astronauts exercise vigorously using specially designed machines aboard the space station. Mar 2, 2016 - Data from astronauts who spent 340 days in orbit will add to almost 55 years of research on how low gravity sends Earthlings for a loop Every second, fluids rush throughout our bodies, and for the Earth-bound, gravity helps move these fluids down into the legs. When it comes to space missions, there are two primary factors that influence the human body: Microgravity and ionizing radiation. What happens if we forget to put our combination of spationaut into space? Temps ... Kazaa thing about to happen in this space. Microbes can change characteristics in space, and microorganisms that naturally live on your body are transferred more easily from person to person in closed habitats like the space station. It has to adjust, and doctors are eager to know more about this process of adjustment. We see these changes across species: humans, mice and other animals. The unfortunate space traveler wouldn't be able to hold their breath for long (if at all), because it would cause lung damage. “I haven’t had to hold my head on top of my neck for five months.”. Strange things happen to the human body in space, and we're going to need to find ways to address them if we want to send astronauts on long-duration missions. Another problem associated with blood in space is the ability to conduct open-type operations so that all the blood simply does not leave the human body. Earth does a pretty good job of keeping us safe from radiation thanks to the magnetic field working in tandem with the atmosphere. Amber Bragdon,Amber Bragdon. What happens to an astronaut's body in space. But what really happens to an unprotected human body isn’t quite as morbid as you might think.
