The Moon’s Mysterious Far Side

Secrets of the Lunar Dark

The Moon has fascinated humanity for centuries, but one of its greatest mysteries lies on the far side—often mistakenly called the "dark side." 

This hidden hemisphere remained unseen until the Space Age, fueling myths, scientific curiosity, and even conspiracy theories. 

Unlike the near side, which is familiar to us due to tidal locking, the far side reveals a vastly different lunar landscape.

Why Is There a "Far Side" of the Moon?

The Moon is tidally locked to Earth, meaning it rotates at the same speed it orbits our planet. 

As a result, only one side is visible from Earth, while the other remains hidden from direct view. 

However, this "far side" is not permanently dark—like all parts of the Moon, it experiences day and night.

How Is the Far Side Different from the Near Side?

Lunar scientists were surprised to find that the far side of the Moon is starkly different from the side we see. 

Key differences include:

• Thicker Crust: The far side has a much thicker crust, which may explain why large maria (lava-filled basins) are rare.
• More Craters: Unlike the near side, which has vast, smooth plains formed by ancient volcanic activity, the far side is heavily cratered, indicating fewer lava flows.
• No Large Lunar Seas: The near side has vast dark plains, known as lunar maria, created by volcanic eruptions. The far side lacks these features, making it more rugged and less geologically active.

First Glimpses: Space Exploration of the Far Side

For most of human history, the far side remained unseen. 

That changed in 1959 when the Soviet Luna 3 probe sent back the first-ever images. 

Since then, several missions have explored this hidden world:

• Luna 3 (1959): First photos revealed a cratered, maria-free surface.
• Apollo Missions: Although no astronauts landed there, they orbited the Moon and mapped the far side in detail.
• Chang’e 4 (2019): China’s Chang’e 4 mission became the first spacecraft to land on the far side, deploying the Yutu-2 rover to explore its unique terrain.

The Far Side and Future Moon Missions

The far side remains a priority for future lunar exploration. 

Scientists believe it holds clues to the early Solar System’s history. Some upcoming projects include:

• Radio Astronomy Stations: Because the far side is shielded from Earth’s radio signals, it’s an ideal place to set up deep-space telescopes.
• Human Missions: Future Artemis missions may explore more of the Moon, with potential plans for astronauts to study the far side firsthand.

Now let’s explore deeper into some fascinating lunar mysteries, upcoming missions, and the best ways to observe the Moon from Earth.

Lunar Mysteries: What We Still Don’t Know

Even with decades of research, the Moon continues to hold secrets. Some of the biggest mysteries include:

1. Why Is the Far Side’s Crust So Thick?

Scientists believe the Moon was formed after a massive collision between Earth and a Mars-sized body (Theia). 

However, why the far side has a much thicker crust remains a mystery. 

One theory suggests that Earth’s heat influenced the near side more, keeping it geologically active while the far side cooled and hardened faster.

2. Does the Moon Have Water?

Recent missions, like India’s Chandrayaan-2 and NASA’s SOFIA, have detected water molecules on the Moon. 

The far side, with its permanently shadowed craters, may have large deposits of ice—potentially useful for future lunar bases.

3. Is There a Giant Metal Object Under the Moon’s Surface?

In 2019, scientists discovered a massive metallic anomaly buried under the Moon’s South Pole-Aitken Basin. 

It could be the remains of an ancient asteroid impact or something even more mysterious.

Upcoming Moon Missions: What’s Next?

The next decade will be packed with lunar exploration. 

Here are some key missions to watch:

NASA’s Artemis Program (2025+)

• Goal: Land astronauts on the Moon, including the first woman and person of color.
• Potential impact: Could set the stage for permanent human presence on the Moon.

China’s Lunar Plans

• Chang’e 6 (2024): Will bring back samples from the far side.
• Chang’e 7 & 8 (2026-2028): Aiming to set up a research station near the Moon’s south pole.

Russia’s Luna 25 & 27 (2024-2027)

• Russia is reviving its Soviet-era Luna program to study lunar ice and regolith.

Private Companies & Lunar Tourism

• SpaceX, Blue Origin, and other private companies are working on Moon tourism and lunar resource extraction.

How to Observe the Moon from Earth

Whether you’re an amateur stargazer or a professional astronomer, observing the Moon can be a breathtaking experience.

1. Best Times to Observe the Moon

• First Quarter & Last Quarter: The best times to see surface details, as shadows cast by the Sun highlight craters and mountains.
• Full Moon: The Moon is brightest but appears flat due to direct sunlight.
• Lunar Eclipses: A total lunar eclipse turns the Moon reddish (Blood Moon).

2. Best Places to See the Moon

• Desert Areas: Low humidity and minimal light pollution (e.g., Atacama Desert, Death Valley).
• High-altitude Locations: The thinner atmosphere improves clarity (e.g., Mauna Kea, Hawaii).
• Planetariums & Observatories: Many host public moon-watching nights.

3. Equipment for Moon Gazing

• Naked Eye: You can see the Moon’s major features.
• Binoculars (7x50 or 10x50): Reveal more details, including craters and maria.
• Telescope (4-8 inches aperture): Best for detailed observation and astrophotography.

Final Thoughts

The Moon is more than just a celestial neighbor—it’s a window into the past and a stepping stone to future space exploration. 

Whether you’re interested in its unexplored far side, upcoming missions, or simply observing it from Earth, there’s always something new to discover.

Conclusion

The far side of the Moon remains one of the most intriguing frontiers in space science. 

Its unique geology, unexplored regions, and potential for future research make it a key focus for upcoming lunar missions. 

With each new discovery, we get closer to unlocking the secrets of our celestial neighbor.
