People have always wanted to travel to Mars, the estimated amount it would take is around 8 moths, this study was meant to test how the astronauts would take it. One may think that the men have a lot of time for sleep, but do they really? The test goes like this:

1. 6 men stay in a small capsule in Moscow for 520 days
2. They will then exit pretending to be doing samples on Mars
3. During that period scientists will take notes on the behaviors and changes of these men 

The test was meant to show how people would manage this flight to Mars if we ever are to send people to the Red Planet. As the scientists observed, tests showed that the men slept more during the last 18.5 weeks rather than the first 18.5 weeks. After this test 4/6 men developed sleep disorders which is very usual when having such a change. 'Messing with sleep can have serious consequences, says Jeffrey Sutton'. So basically after all the testing scientists have figured out that if they were to send people to Mars they could be faced with sleeping problems with many lead to worse consequences.

I chose to read this article because it was about space which seemed interesting. The article was short and there for it wasn't boring! I didn't know people never went to Mars, but now I do:)
