Unlocking the Moon’s Secrets

Scientists have made groundbreaking discoveries about the moon’s history and composition, thanks to China’s Chang’e-4 space program. This mission successfully landed on the far side of the moon in 2018, providing new insights into the lunar surface.

Unlocking the Moon's Secrets

Layers of Lunar Surface

Surface Composition: Chang’e-4 has revealed that the top 130 feet (40m) of the moon’s surface consists of layers of dust, soil, and fragmented rocks. These layers provide clues about the moon’s geological history.

Impact Crater and Lunar Lava Layers

Formation of Crater: Within these layers, scientists discovered an impact crater caused by a massive collision on the moon’s surface. This collision left a significant mark on the moon’s geological features.

Lunar Lava Flows: Beneath the surface layers, five distinct layers of lunar lava were found. These layers originated billions of years ago and were created by volcanic activity.

Moon’s Formation and Evolution

Moon’s Birth: The moon is believed to have formed around 4.51 billion years ago when a Mars-sized object collided with Earth, leading to the separation of a portion of Earth’s material.

Continued Impacts and Volcanic Activity: Over millions of years, the moon experienced further impacts from space debris, causing cracks in its surface. The moon’s mantle contained molten magma, which seeped into these cracks due to volcanic activity.

Cooling and Geologically “Dead” Moon

Gradual Cooling: As time passed, the moon’s volcanic activity gradually diminished, and the moon began to cool down.

Energy Depletion: The energy powering the moon’s volcanic activity weakened over time, leading to the decline of volcanic processes.

Ongoing Exploration and Future Discoveries

Chang’e-4’s Mission: Chang’e-4’s mission is far from over, and researchers are enthusiastic about the potential for further groundbreaking discoveries.

Magma Possibilities: While the moon is largely considered “geologically dead,” there are suggestions that pockets of magma could still exist beneath the lunar surface.

Unveiling Lunar History: China’s Chang’e-4 mission has allowed scientists to explore the moon’s past and gain insights into its geological evolution.

Continued Exploration: Chang’e-4’s ongoing mission promises to reveal more about the moon’s composition, history, and potential hidden features.
