DIGS on The Moon – Pt 1 – Fun Facts

DIGS on the Moon – Part I

Read DIGS on the Moon Part I?  So many fun facts we can talk about here, but let us limit ourselves to a few!

  • Length of a Moon Day:  One day on the moon is equal to about 28 days on Earth. This is the amount of time it takes the moon to complete one rotation around its axis. It is also known as one lunar day.
  • Temperature Variations in the Moon:  During the lunar day which equals about 13 earth days, the temperature can be as high as 253 degrees Fahrenheit and during the lunar night it can be as low as minus 387 degrees Fahrenheit (that is lower than the temperature at which oxygen turns from liquid to solid!). These extreme temperatures are caused by lack of any atmosphere surrounding the moon, and therefore it cannot block or trap the sun’s rays.
  • Many Animals Can Hear Higher Sound Frequencies Than Humans:  Hertz is a unit that scientists use to measure sound waves. Human beings can hear sound waves that range from 20 Hertz to 20,000 Hertz. Dogs can hear 67 Hertz to 44,000 Hertz.There are animals that can hear higher frequencies than dogs.  Cats can hear sounds as low as 55 Hertz and as high as 79,000 Hertz. Bats and whales can hear sounds up to 150,000 Hertz and sometimes even higher depending on the species. However, we couldn’t possibly send a beluga whale to rescue Captain Carter, could we!?!
  • Could This Story Really Have Happened?  Well, in all honesty, no, and not because we do not believe in ultra smart canines.  The fact is that sound needs something to travel through – what we call a “medium”.  The medium sound uses to travel on Earth is air.  The moon does not have an atmosphere, so technically sound cannot travel, unless it is transmitted through the ground. Sound can travel through rocks/ground, but that requires very high intensity earthquake waves to cause sounds that can be heard. So the whole idea of sending up a dog with the hope that they could hear something humans could not is a pretty faulty argument.  I hope some of you caught this little inconsistency in the story!
  • Where is Cape Canaveral and Why Is It Important:  Cape Canaveral is in the state of Florida. It is the location for the Kennedy Space Center and the launch facility for NASA space flights. The control or command center for the space flights is located at the Johnson Space Center in Houston. Texas. That is why you always catch astronauts in movies talking to “Houston”!
  • Why Does the Moon Have So Many Craters?  The Earth and Moon’s atmosphere is constantly under attack by space rocks of a variety of sizes – from small meteorites to large asteroids.  The Earth’s atmosphere is thick and dense enough to cause friction to the extent that most of the space rocks disintegrate on entry into the earth.  A burning meteor at night is what we like to call a “shooting star”. However, the moon does not have an atmosphere, which means that the space rocks can continue to the surface, unchallenged. That is why you see a variety of crater sizes on the surface of the moon.
