Questions and Answers

What is the primary scientific significance of the Chang'e 6 mission successfully returning samples from the Moon's far side?

  • It provides an opportunity to test the resilience of robotic arms and drills in the harsh conditions of the lunar surface.
  • It demonstrates the feasibility of creating flags made entirely of basalt on the Moon's surface, opening new possibilities for lunar art.
  • It allows scientists to study materials from a region of the Moon with a unique geological history, potentially revealing new insights into the early Solar System. (correct)
  • It confirms China's capabilities in lunar missions, showcasing their technological advancements in space exploration.

The South Pole-Aitken (SPA) basin is significant for which of the following reasons?

  • It is believed to contain valuable water ice deposits that could be used to support future lunar missions.
  • Its immense size and age may provide insights into the early history of the Moon and the Solar System due to its potential to expose deep crustal material. (correct)
  • It is the most easily accessible landing site on the far side of the Moon due to its relatively flat terrain and lack of obstacles.
  • It is the only location on the Moon where basalt can be found in large quantities, making it ideal for creating lunar flags.

Why was basalt chosen as the material for the Chinese national flag planted on the Moon by the Chang'e 6 mission?

  • Basalt is highly reflective, making the flag more visible in the low-light conditions of the lunar surface.
  • Basalt is a readily available material on the Moon, demonstrating the potential for utilizing lunar resources. (correct)
  • Basalt is resistant to extreme temperatures and radiation, ensuring the flag's long-term survival on the Moon.
  • Basalt is a lightweight material, which reduced the fuel consumption required to transport it to the Moon.

Study Notes

  • China's Chang'e 6 lunar probe achieved a milestone on June 25, 2024
  • It brought back soil samples from the Moon's far side, which marks the first return of materials from this unexplored lunar region
  • Chang'e 6 is named after the Chinese Moon goddess
  • It launched from Hainan province in South China on May 3, 2024
  • The spacecraft's journey ended on June 2, 2024, landing in the South Pole-Aitken (SPA) basin
  • This basin measures approximately 1,600 miles (2,500 km) wide and 5 miles (8 km) deep
  • The SPA basin is among the largest and oldest impact craters in the Solar System
  • The lander's first task involved planting China's national flag on the lunar surface
  • The flag is about 12 by 8 inches (300 mm by 200 mm), and is made of basalt
  • Cao Genyang from Wuhan Textile University explored the possibility of using basalt as a high-performance inorganic fiber
  • Chang'e 6 used a drill and robotic arm to collect rocks and soil samples
  • The lander also captured photos of the lunar surface
  • The sample-carrying rocket lifted off on June 4, 2024, and entered the Moon's orbit before docking with the Chang'e 6 orbiter
  • The Chang'e 6 orbiter transferred the samples to the return capsule for the journey back to Earth
  • The capsule with about four pounds (two kg) of lunar material, landed safely in the grasslands of Inner Mongolia on June 25, 2024
  • It was transported to the China Academy of Space Technology in Beijing
  • Chinese officials intend to distribute portions of the collected soil and rocks to researchers in China and internationally for analysis
  • Scientists anticipate the materials will provide insights into the Moon's far side evolution
  • the samples could explain the differences between the near and far sides of the Moon
  • This research may provide shed light on the early history of the solar system
  • China plans to explore the Moon's south pole
  • The upcoming uncrewed missions, Chang'e 7 launch in 2026 and Chang'e 8 launch in 2028, will search for water and other resources
  • Future plans include sending crewed missions in 2030, and building a permanent base at the south pole
