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.
