The concept of the ” side of the moon” has always fascinated people. It is actually a misconception. In reality there isn’t a side of the moon. Instead there is a side that’s not visible, from Earth and often referred to as the “dark side.” As the moon orbits around Earth different sides receive sunlight at times due to its rotation patterns and gravitational interactions with our planet.
The moon takes 27.3 days to complete one rotation on its axis, which coincides with its orbit around Earth. This phenomenon called locking causes one side of the moon to be visible from our perspective on Earth. The near side, which faces us shows phases of the moon from moon to full moon as it gradually reveals or conceals parts of its illuminated surface. On the hand the far side remains hidden from our view. Receives just as much illumination, during its rotation.
Common Misunderstandings Regarding the Dark Side
There is a misconception that the “dark side of the moon” refers to a shadowed side. However this is not accurate. In reality both sides of the moon experience periods of daylight and darkness as it orbits around the Earth. The term “dark side” has been popularized in music contributing to this myth. Another misconception is that the dark side of the moon harbors lands or countries when in fact it remains devoid of settlements.
Throughout its phases the moon undergoes a phenomenon called libration. As a result telescopes allow us to observe more, than 50% of its surface even though one side always faces Earth.
Misconceptions about Exploration
Many people mistakenly believe that space agencies like NASA have never explored the so called dark side of the moon. However this is incorrect. While it is true that no human astronaut has ever landed on the side of the moon there have been robotic missions and telescopes dedicated to gathering valuable information about this lesser known region, on our lunar surface.
Some notable missions that have successfully explored the side of the moon include the Luna 3 probe, by the Soviet Union in 1959 which captured and transmitted the images of this region and the Chang’e 4 mission by China in 2019 which successfully landed a rover on the far side for scientific research. These examples demonstrate that contrary to belief scientists have shown interest in exploring and discovering valuable information from what is often referred to as the “dark side” of the moon.
Importance of Scientific Exploration
It is important to understand NASA’s involvement when delving into the exploration of this region. The astronauts from NASA’s Apollo missions were actually the humans to witness what we perceive as a “side although it is more accurately a matter of perspective and not constant darkness. Moreover significant attention is given to studying volatiles found in samples, such as investigating their abundance, distribution and sources within the moon itself.
Role of Lunar Reconnaissance
A tool utilized for exploration is NASA’s Lunar Reconnaissance Orbiter (LRO). This spacecraft has provided scientists with images and valuable data about aspects of our satellites surface including crucial insights, into its far side.The Lunar Reconnaissance Orbiter (LRO) has captured images of craters, basaltic plains known as maria and other intriguing features, on the lunar surface. These images help scientists gain an understanding of the moons history and evolution.
Other Spacecraft Missions
Other space agencies besides NASA have also contributed to exploring the known side of the moon. Countries spacecraft missions have collected data to expand our knowledge about this mysterious lunar region. For instance the Center for Lunar Origin and Evolution focuses on the moons largest impact basin, which stretches from near the south pole and covers a significant portion of the southern hemisphere on its far side.
As you delve into your studies regarding the side of the moon it’s important to remember that scientific exploration continually uncovers information. The findings from missions like these enhance our understanding of how the moon originated and provide insights into prospects for exploration. By maintaining a mindset and keeping up with lunar discoveries you can stay informed, about this captivating celestial body.
Orbit of the Moon
To grasp an understanding of the side of the moon it is crucial to familiarize yourself with its orbit. The moon revolves around Earth completing one orbit in 27.3 days.
As the Moon moves it is influenced by the pull of both the Earth and the Sun. Because of this one side of the Moon always faces towards the Earth, which is called the side. The other side, known as the side or sometimes referred to as the side cannot be seen from Earth. However it’s important to note that both sides receive sunlight at points during the cycle so it’s not actually completely dark.
The rotation of the Moon, on its axis is another factor in understanding why we refer to one side as the side. Like its orbit around Earth it takes 27.3 days for one complete rotation of the Moon. This synchronicity between its orbit and rotation means that we always see one face of the Moon from Earth. This phenomenon is called locking. Happens because gravitational forces, between our planet and its natural satellite have gradually slowed down its rotation until it reached a state where it remains fixed in this synchronized position.
The different phases of the moon have a role, in revealing the side that is not usually visible. As the moon moves around the Earth its position in relation to the Sun and Earth causes varying amounts of sunlight to be reflected on its surface. This results in phases;
- New Moon: The side facing Earth is not lit by sunlight. It appears invisible.
- Waxing Crescent: A small portion of the side becomes visible. Gradually grows larger.
- First Quarter: Half of the side can be seen.
- Waxing Gibbous: More than half of the side is visible. Continues to grow.
- Full Moon: The entire illuminated side can be seen.
- Waning Gibbous: The illuminated side starts to become less visible.
- Quarter: Half of the side becomes visible again but on the opposite side from before.
- Waning Crescent: A small portion of the illuminated side remains visible gradually decreasing until a new moon phase occurs.
Each lunar phase brings its cycle of illumination and darkness to what’s commonly referred to as “the dark side” of the Moon. This sheds light on a misconception that it’s always in darkness. Understanding these concepts allows for confident and accurate discussions, about this aspect of our moon.
The Moon’s Influence on Earth
The moon is Earth’s only natural satellite and the fifth largest moon in our solar system. Although the moon does not give off light of its own, its presence has notable effects on planet Earth.
The moon’s gravitational pull is responsible for the rise and fall of ocean tides on Earth. As the moon orbits around our planet, its gravity creates a bulge in the oceans nearest to it. There is also a bulge on the opposite side of Earth. These alternating bulges result in high and low tides.
The moon’s orbit around Earth also leads to solar and lunar eclipses. A solar eclipse occurs when the moon passes between the Sun and Earth, blocking our view of the Sun. A lunar eclipse takes place when Earth moves between the Sun and the moon, casting a shadow on the lunar surface.
- The moon helps stabilize Earth’s rotation axis. This provides a relatively stable climate over thousands of years.
- Some researchers believe the moon’s gravity may have played a role in the early stages of life evolving on Earth.
- The moon’s gravitational pull is thought to produce small tremors and earthquakes on our planet.

Frequently Asked Questions
What makes the far side of the moon unique?
The far side of the moon often referred to as the ” side ” possesses characteristics in terms of composition and appearance compared to its near side counterpart. It features a crust and more impact craters due to volcanic activity. Contrary to belief it does receive an amount of sunlight as its near side.
Why is it that we can never see the side of the moon from Earth?
The dark side of the moon remains hidden from our view due to a phenomenon known as locking. This means that while orbiting around Earth the moon rotates on its axis at the rate causing only one side to be permanently visible, to us.
Has NASA ever explored the side of the moon?
Absolutely! NASA has conducted missions to explore this territory. The Lunar Orbiter missions in the 1960s were responsible for capturing some of our images from that region.
