  • Chinese space officials say a spacecraft has successfully collected samples from the moon and is headed back toward Earth.
  • 2
  • The unmanned spacecraft, called Chang'e-6, touched down on the lunar surface on Sunday.
  • 3
  • It launched May 3 from a Chinese space center in southern China and was carried to space aboard a Long March 5 rocket.
  • 4
  • Space officials and Chinese media said the spacecraft landed in an area of the moon's South Pole, called the Aitken Basin.
  • 5
  • This area is known as the far side of the moon because it permanently faces away from Earth.
  • 6
  • NASA describes the Aitken Basin as the largest impact basin on the lunar surface.
  • 7
  • The distance from the basin's lower depths to its highest points is estimated to be over 15 kilometers.
  • 8
  • That is nearly twice the height of Earth's tallest mountain, Mount Everest.
  • 9
  • Controllers back on Earth then directed the space vehicle to use its drilling equipment and other tools to capture soil and rock samples.
  • 10
  • Space officials said earlier that Chang'e-6 was expected to collect up to two kilograms of soil and rock samples.
  • 11
  • The collection operation was completed by Monday.
  • 12
  • Then on Tuesday, the spacecraft lifted off from the lunar surface carrying the samples on the trip back to Earth.
  • 13
  • The Beijing Daily newspaper reported the spacecraft displayed China's national flag at the spot where the samples were collected.
  • 14
  • China's National Space Administration said in a statement that Chang'e-6's success showed it was able to survive "the test of high temperature on the far side of the moon."
  • 15
  • After launching from the lunar surface, the spacecraft was to link up with another spacecraft currently orbiting the moon.
  • 16
  • The samples would then be passed to another spacecraft designed to transport the material to Earth for study.
  • 17
  • Space officials said the planned landing is expected to take place around June 25.
  • 18
  • It is not the first time a Chinese spacecraft has collected material from the lunar surface.
  • 19
  • The country's Chang'e 5 spacecraft traveled to the moon in late 2020.
  • 20
  • It successfully brought back about two kilograms of moon rocks and dust.
  • 21
  • That mission was carried out in an area known as Oceanus Procellarum.
  • 22
  • It sits on the western edge of the near side of the moon.
  • 23
  • That area is believed to have had intense volcanic activity in ancient times.
  • 24
  • But if the second Chinese collection attempt is successful, it will be the first time lunar samples from the far side of the moon have made it to Earth.
  • 25
  • China is the third nation to successfully collect lunar samples, following the United States and the Soviet Union.
  • 26
  • The last such mission happened in 1976, when an unmanned Soviet spacecraft collected 170 grams of moon material.
  • 27
  • America's Apollo program - which first put humans on the moon - landed 12 astronauts over six flights from 1969 to 1972.
  • 28
  • Those missions resulted in astronauts collecting about 382 kilograms of rocks and soil.
  • 29
  • Missions to the moon's far side are more difficult because the area faces away from Earth.
  • 30
  • This requires the use of a special satellite to establish and keep communications.
  • 31
  • The terrain is also more difficult to explore, with fewer flat areas to land.
  • 32
  • China has additional unmanned lunar missions planned as well.
  • 33
  • In 2026, the country's Chang'e-7 spacecraft will aim to further explore the south polar area, including searching for water ice.
  • 34
  • Then in 2028, Chang'e-8 will carry out a series of experiments in preparation for building a long-term science base on the moon.
  • 35
  • China has said it aims to put its astronauts on the moon by 2030.
