 ==== Trained in Iceland ==== ==== Trained in Iceland ====
 The Apollo mission astronauts were trained in Iceland because it was thought that its terrain most closely resembled that of the Moon. [([[https://orbit.spacenation.org/iceland-apollo-astronauts/|Space Nation]])] The Apollo mission astronauts were trained in Iceland because it was thought that its terrain most closely resembled that of the Moon.

 +==== Moon's rotation ====
 +The moon's rotation - the time it takes to rotate once on its own axis - takes the same amount of time as the moon takes to complete one orbit of the Earth or about 27.3 days. This means that the moon's rotation is synchronized in such a way that the moon shows the Earth in the same hemisphere at all times. [([[https://www.space.com/24871-does-the-moon-rotate.html|Space]])]
 +
 +==== Dark side of the moon ====
 +The dark side of the moon does not exist. Both sides of the moon receive the same amount of sunlight, but only one side of the moon is seen from Earth. [([[https://spacecentre.co.uk/blog-post/dark-side-of-the-moon-blog/|Space Center]])]
 +
 +==== Earth had no moon ====
 +At the beginning of its existence, Earth had no moon. At some point in Earth's early history, a planet, larger than Mars, struck Earth. Immediately, most of the planet and a sizable chunk of Earth were vaporized. The cloud rose to an altitude of more than 22,000 kilometers, where it condensed into countless solid particles that orbited the globe as they merged into larger and larger moons, which eventually merged into a single moon. [([[https://www.nhm.ac.uk/discover/how-did-the-moon-form.html|National History Museum]])]
 +
 +==== Moon has no atmosphere ====
 +The Moon has no atmosphere. The Moon's surface is unprotected from cosmic rays, meteorites, and solar winds and has huge temperature fluctuations. The lack of an atmosphere means that no sound can be heard on the Moon, and the sky always appears black. [([[https://www.vedantu.com/question-answer/explain-why-a-there-is-no-atmosphere-on-the-moon-class-11-physics-cbse-5f92389d27a1a84a38de16b5|Vedantu]])]
 +
 +==== The distance ====
 +The distance between the Earth and its moon averages about 384,000 kilometers (238,855 miles). The diameter of the moon is 3476 kilometers. The mass of the moon is about 1.25%j the mass of the Earth. [([[https://spaceplace.nasa.gov/moon-distance/en/|Space Place]])]
 +
 +==== Moondust ====
 +Moondust smells like gunpowder. That's what the astronauts claim. [([[https://science.nasa.gov/science-news/science-at-nasa/2006/30jan_smellofmoondust|NASA Science]])]
 +
 +==== Twelve Americans ====
 +Only 12 people walked on the moon. They were exclusively American citizens. [([[https://solarsystem.nasa.gov/news/890/who-has-walked-on-the-moon/|Solar System]])]
 +
 +==== High-speed Internet ====
 +There is high-speed Internet on the moon: 19 Mbps. [([[https://www.smithsonianmag.com/smart-news/you-can-now-get-high-speed-internet-moon-180951614/|Smithsonian Mag]])]
 +
 +==== Shaped like an egg ====
 +The moon is not round - it is shaped more like an egg. [([[https://earthsky.org/space/five-myths-about-the-moon/|EarthSky]])]
 +
 +==== Moonquakes ====
 +Lunar quakes, which occur several kilometers below the Moon's surface, may be the result of the Earth's gravitational pull. [([[https://www.space.com/moonquakes-moon-is-shrinking-apollo-data.html|Space]])]
 +
 +==== More computing power ====
 +Your cell phone has more computing power than the computers used for the Apollo 11 moon landing. [([[https://www.zmescience.com/science/news-science/smartphone-power-compared-to-apollo-432/|ZME Science]])]
 +
 +==== Apollo 11 tapes ====
 +The original tapes of the Apollo 11 moon landing were erased by mistake, by re-recording something else. [([[https://www.reuters.com/article/us-nasa-tapes-idUSTRE56F5MK20090716|Reuters]])]
 +
 +==== Flags on the moon ====
 +Flags placed on the moon are now white due to solar radiation. [([[https://www.smithsonianmag.com/air-space-magazine/faded-flags-on-the-moon-32929921/|Smithsonian Mag]])]
 +
 +==== Piece of the Wright brothers' plane ====
 +When Neil Armstrong first walked on the moon, he carried a piece of the Wright brothers' first airplane with him. [([[https://time.com/5418950/first-man-neil-armstrong-wright-flyer/|Time]])]
