In 1961 when Yuri Gagarin returned from space Nikita Khrushchev wanted to boost the Soviet’s anti-religion campaign by saying: “Gagarin flew into space, but didn’t see any god there.”
The first woman to have flown into space(1963), Valentina Tereshkova, also volunteered in 2013 to go on a one-way trip to Mars.
Yuri Gagarin’s heart was beating at 64 beats per minute just half an hour before the launch that would bring him to space. 64 BPM is lower than the average person’s pulse just after waking up in the morning.
The first man to fly and the first man to walk on the moon were alive at the same time. Neil Armstrong was 17 when Orville Wright died.
A man named Roger Boisjoly and his colleagues attempted to stop Challenger from lifting off into space knowing that a disaster would happen, but ultimately failed.
Astronauts must have good airflow around them when they sleep, otherwise they, “…could wake up oxygen-deprived and gasping for air, because a bubble of their own exhaled carbon dioxide had formed around their heads.”
A Soviet probe, “Luna 15”, crashed into the surface of the moon while Buzz Aldrin and Neil Armstrong were still on it.
Scientists are working on a nuclear fusion rocket which could reach Mars in 30 days.
A pile of Neil Armstrong’s poop is sitting somewhere on the moon.
If you were were exposed to outer space without a suit, after about 15 seconds, you would be blue, bloated, and in an unresponsive stupor, but not dead. If they got you back inside and gave you oxygen within about 90 seconds, you’d likely make a complete recovery with only minor injuries.
