Isolation for long space missions

Hi,
so I was watching Michael Stevens’s first and only free episode of Mind Field where he was talking about isolation. He mentioned that there were experiments of people in closed systems to test how body and mind reacts to long term isolation.


In 1989 Stefania Follini was for 130 days in a cave without any visitors, she could only communicate via “internet”. She also had books to read and some small animals like mice. Her menstruation stopped at some point, she slept for about 10 hours and was awake for 20-25! Also during the visit she lost 7.7 kilograms. This is not the longest isolation at all.

NASA also did in the last few years isolation of 6 people for 8 and later 12 months. This was to test the team work of the people since they were closed together cabin fever showed up, but they did not have to cancel the mission. In 2007 Russians did experiment called Mars 500 where six males stayed together for even longet rime, 520 days, only artificial light as before, they brought with them books and games or dvds but they had limited connection with outside world.

Eight months in “cabin” (project HI-SEAS)

Michael Stevens on the other hand spent “only” 3 days in isolation, but it was a bit different. He was in soundproof small room with white walls, white and black bottles with food and water, sink and toilet. This had dramatically different effects. He had halucinations and could not really tell apart dream from reality, also at one point he was counting bottles and counted 6 instead of 9 ­čśÇ

What are such experiments for? You want to know what happens to body if it is thrown out of its rhytm and mind too. When we are finally able to get to Mars we need people that are capable of staying in small spaceship for months and months.

Apollo missions: Apollo 8

Hi, nášivka
two months after Apollo 7 NASA launched next mission: Apollo 8. It was December 21st of 1968 when Borman, Lovell and Anders sat in Saturn V rocket. Uniqueness of this crew is that captain (Borman) was not the most experienced member because Lovell was already on two missions while Borman only on one.

This mission skipped some other plans of NASA right to testing all modules n the orbit around Moon. This was because of such a little time for finishing main mission, landing on Moon with men.
Even that there was such a sudden change in program, Borman and his crew spent 7 hours on simulator for each hour of the flight.

Mission was 6 days long. It was going without problems, they used three stages of fuel so they got up on Earth┬┤s orbit and then for two and half an hour they were checking if everything is going well. They were also rotating rocket so they could take some pictures of Earth, they were first human who saw whole Earth.

Since they crossed radiation belt they received about 1.6 miligray (Maybe I will talk about that next time) while normal dose on Earth per year is 2-3 mGy.

Through whole flight spacecraft had to be rotating because without atmosphere heat shield would crack because of high temperatures (200 ┬░C) and on the other side it would be freezing (-100 ┬░C).

Because crew had some sleep problems Borman after few hours of sleep woke ill and then he was vomiting. It was very difficult to clean it up because of no gravity and he wanted not everybody to know.

After orbiting the moon and collecting data they made re-entry (most dangerous part of flight) to Earth┬┤s atmosphere as is shown on the picture.
