Question 1

True or false: Chang'e 5 returned to Earth with nearly 2 kilograms of lunar soil and rock samples.

Accepted Answer

True. It brought back 1,731 grams—about 1.7 kg—of material from Oceanus Procellarum, the first lunar sample return since 1976.

Question 2

True or false: The Chang'e 5 mission was the first to successfully collect samples from the Moon's far side.

Accepted Answer

False. Chang'e 5 landed on the near side. The far-side sample return was achieved later by Chang'e 6 in 2024.

Question 3

True or false: Chang'e 5's lander carried a small rover that deployed and explored the landing site for three days.

Accepted Answer

False. No rover was included. The lander used a robotic arm and drill to collect samples, but it remained stationary.

Question 4

True or false: Chang'e 5's launch rocket was a Long March 5B, the same model used for China's space station modules.

Accepted Answer

False. It launched on a Long March 5 (not 5B). The 5B variant lacks an upper stage and is optimized for heavy payloads to LEO.

Question 5

True or false: The Chang'e 5 samples are helping date a younger volcanic region on the Moon at about 2 billion years old.

Accepted Answer

True. Radiometric dating of the samples confirmed volcanic activity 2 billion years ago, filling a key gap in lunar thermal history.

Question 6

True or false: Chang'e 5's return capsule used a 'skip reentry' technique to slow down before landing in Inner Mongolia.

Accepted Answer

True. It bounced off the atmosphere once to reduce speed and heat, similar to Apollo capsules, ensuring a safe landing.

Question 7

True or false: China's Chang'e 5 mission was the first lunar sample return conducted entirely by a single spacecraft.

Accepted Answer

False. The mission used four modules (orbiter, lander, ascender, returner) that separated and docked in lunar orbit.

Question 8

True or false: Scientists discovered a new mineral, Changesite-(Y), within the Chang'e 5 samples.

Accepted Answer

True. In 2022, Chinese researchers identified this phosphate mineral, never before found in lunar or terrestrial rocks.
