The Groundbreaking Chang’e-5 Mission
Introduction to Chang’e-5
The Chang’e-5 mission, launched by the China National Space Administration (CNSA), aims to retrieve lunar rock and soil samples from the Moon, marking a significant step in China's ambitious space exploration program. This mission, accomplished in December 2020, showcased China's advancements in robotic space technology and its commitment to making strides in lunar exploration.
The Goals of Chang’e-5
The primary objective of the Chang’e-5 mission was to collect approximately 2 kilograms of lunar material, which would be the first such samples returned to Earth since the Soviet Luna 24 mission in 1976. The mission also sought to conduct scientific research on the geology of the Moon, particularly its volcanic history.
The Journey to the Moon
Launch and Landing of Chang’e-5
On November 23, 2020, the Chang’e-5 spacecraft embarked on its journey from the Wenchang Space Launch Site in Hainan, China. It successfully landed on the Moon’s surface on December 1, 2020, in the Oceanus Procellarum region, a vast area of basaltic plains. This site was strategically chosen for its relatively young surface, allowing scientists to gather insights into the Moon's geological past.
Collecting Lunar Samples
Once on lunar soil, the Chang’e-5 lander deployed a robotic arm to scoop up lunar regolith and rock samples. The collection process lasted for approximately two days, demonstrating China's technical capabilities with high precision and efficiency in automatic sample collection.
The Return to Earth
Chang’e-5’s Remarkable Return
The return phase took place shortly after sampling, as the spacecraft launched back into lunar orbit on December 3, 2020. It successfully rendezvoused with its orbiter and began its journey back to Earth, highlighting the successful layout and design of the mission.
Final Descent and Sample Retrieval
After travelling through space, Chang’e-5 made a safe splashdown in the Inner Mongolia region of China on December 17, 2020. The retrieval of the collected samples excited scientists worldwide, as it set the stage for extensive research into lunar geology and the early solar system.
Fun Fact
Achievements of Chang’e-5
The Chang’e-5 mission is significant not only for its success in obtaining samples but also as China became the third nation, after the USA and the Soviet Union, to bring lunar samples back to Earth, marking a profound achievement in space exploration.
