Gizmodo: The Biggest Health Risks to Humans in Space

With the The Martian rocketing to the top of box offices worldwide this week, the challenge of surviving on Mars is on everyone’s mind. But while the science in The Martian is pretty solid, there is one obstacle Mark Watney rarely had to cope with: his own body.

During his two years alone on the Red Planet, Mark Watney never fell sick. He never had to splint his own bones or pass a kidney stone, never suffered a bout of insomnia or depression, never got cancer. But real astronauts traveling to Mars could face all of these unpleasantries and more. That’s why NASA has tasked a small army of biomedical researchers with studying how the human body and mind are impacted by long stints in space. Gizmodo spoke with the experts to learn about the biggest health risks facing our astronauts, and what we can do to mitigate them.

This Is What One Year In Space Does To Your Body

The Verge: Here’s what one year in space does to your body

Want to know how much poop an astronaut produces while spending a year on the International Space Station? It's somewhere around 180 pounds.

That fun fact is brought to you by NASA, which just released an infographic breaking down all the numbers surrounding astronaut Scott Kelly's one-year stay on the ISS. Kelly and cosmonaut Mikhail Kornienko are both in the midst of spending a full year on the station as part of the One Year Mission — an experiment to study the long-term effects of spaceflight on the human body. The mission will help NASA better prepare for its eventual journey to Mars in the 2030s. A trip to the Red Planet is going to take multiple months, so NASA wants to know how the microgravity environment of space will affect the body during that time.

CSN Editor: One year in space .... that is a long time.

Space 'Causes Disabling Headaches In Astronauts'

From The Telegraph:

Astronauts who have no history of bad headaches can be prone to disabling attacks while in space, neurologists say.

Contrary to prevailing theories, headaches in space are not caused by motion sickness, they said.

Instead, the problem could lie in an increase in blood flow to the head, causing painful pressure on the brain.
