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

“Astronaut Scott jelly will see 10,944 sunrises and sunsets during the “Year in Space” mission”. So to save time, Kelly and a NASA sonographer visited a tattoo parlor on Earth, where the dots of ink were permanently applied at the right spots.

Kelly’s and Kornienko’s mission will not remotely answer all of the biomedical riddles space raises.

Scott Kelly’s and Mikhail Kornienko’s one year aboard the worldwide Space Station should help scientists understand what problems might arise during prolonged spaceflight. The information will be invaluable as NASA looks to send a manned mission to Mars sometime in the 2030s. NASA released the below infographic on Monday pointing out some key data points around the effect of a year in space on the human body and at least one about the effect of human waste on space.

Another astronaut, Mark Kelly, stated that the ability to go to Mars is not based on technology and engineering challenges. “I feel pretty good overall”, he added. On hand were NASA astronauts Terry Virts, Mark Kelly and a special guest who beamed in from on orbit – Kelly’s brother Scott. “And that’s why we’re studying this”, said Scott Kelly, NASA Astronaut.

Prepare for some more, because that’s not the end of it. It turns out that pee and sweat are recycled on the space station, so Kelly will have around 730 liters (193 gallons) of his own stuff to keep him hydrated.

Surprisingly enough, this actually isn’t the first time that NASA has been a bit careless in identifying bodies in space. Kelly’s tattoos were one simple workaround, but others are more complex.

Not only are the Kelly sharing many genetic traits, they also have has careers that were similar, both were pilots in the Navy who later become astronauts during 1996.

For instance, they’ve had their eyes and their vision closely monitored to pin down any potential changes due to increased intracranial pressure, in turn the result of fluid shifts in the upper body because of weightlessness.

You might want to reconsider, as scientists say that burning feces might not sound so glamorous, but they resemble very much a dying star. “I think even most prisoners can get outside occasionally in a week”.
