[앵커]Humanity’s last manned lunar probe was Apollo 17, launched regarding 50 years ago. As a result of recent analysis of lunar surface rocks brought back by astronauts at the time, it was confirmed that the moon is at least 4.46 billion years old. That’s 40 million years older than previously known. Lee Dong is a reporter.[기자]In 1969, humans first set foot on the moon when Apollo 11 successfully landed on the moon. Starting with this, six Apollo spacecraft landed on the moon, and 12 astronauts stepped on the lunar surface. The last probe was in 1972. Apollo 17 was launched in 2008. The two astronauts who landed on the moon at the time collected rocks from the lunar surface while traveling regarding 36 km in a lunar vehicle. Of the 110 kg of soil and rock samples brought to Earth in this way, some were stored for future research. However, a new fact was recently discovered: the moon is over 4.46 billion years old, 40 million years older than previously known. The lunar sample contained small zircon crystals, and analysis showed that these minerals are It was confirmed to have been created 4.46 billion years ago.[장 비둥 / UCLA 지구행성우주과학과 부연구원 : 원자탐사기를 이용해서 먼저 (지르콘 결정의) 원자 위치를 하나씩 세어보고 그것들이 어디에 있는지 살펴봤습니다. 그런 다음 광물의 나이가 실제로 맞는지 확인했습니다.]It is known that the moon’s surface was formed when magma hardened, and since minerals are formed following magma cools, the moon’s age is bound to be older than the age of zircon. The research team believes that the moon has an influence on the Earth’s rotation and natural phenomena. He emphasized that it is important to study the initial creation process.[장 비둥 / UCLA 지구행성우주과학과 부연구원 : 달은 매우 안정적인 환경을 가지고 있어서 아주 오래된 충격이나 행성에 미친 여러 사건을 체계적으로 기록할 수 있습니다. 그래서 달은 지구상에 기록되지 않은 많은 현상을 기록하는 핵심 자료가 됩니다.]Next year, the U.S. manned probe Artemis 3 is scheduled to explore the moon once more for the first time in half a century. Attention is focused on whether human science accumulated over the past 50 years since Apollo will be able to unlock the remaining clues to the moon. YTN Science Lee Dong-eun.
