50 Facts About the Apollo 11 Moon Landing

In honor of the mission to put the first man on the moon’s 50th anniversary, Mental Floss posted 50 Facts About the Apollo 11 Moon Landing.  Here are three of my favorites…

3. THE APOLLO 11 ASTRONAUTS WERE ODDLY CALM DURING LIFTOFF.
The average resting heart rate of an adult human is somewhere between 60 and 100 beats per minute (bpm), depending on the individual’s age, size, heart conditions, and other factors. Throw a little excitement into the mix and one’s heart is likely to beat much faster. Yet the Apollo 11 astronauts, whose heart rates were monitored throughout the expedition, remained surprisingly normal. At liftoff, Armstrong was the most excited of the bunch with a rate of 110 bpm. Collins, meanwhile, was clocked at 99, while a clearly calm Aldrin logged a rate of just 88 bpm.

32. ARMSTRONG AND ALDRIN HAD TO BE CAREFUL NOT TO LOCK THEMSELVES OUT OF THE MODULE.
If their heart rates were any indication, Armstrong and Aldrin were pretty calm, cool, and collected when they landed on the Moon. And it’s a good thing: Had they been overwhelmed by the cosmic wonder of it all, they could have easily locked themselves out of their lunar module, as Eagle’s door had no outer handle.

45. ARMSTRONG, ALDRIN, AND COLLINS WERE QUARANTINED FOR MORE THAN TWO WEEKS UPON THEIR RETURN TO EARTH.
On July 24, the Apollo 11 crew reentered Earth’s atmosphere and splashed down into the Pacific Ocean after more than a week in space. In order to ensure the men hadn’t brought back any sort of weird Moon diseases or other microbes, Armstrong, Aldrin, and Collins were quickly placed into a mobile quarantine unit, which was then transported to the NASA Lunar Receiving Laboratory at Houston’s Johnson Space Center. They were released from quarantine on August 10, 1969.
