Samples from China’s moon missionDate: 27 September 2021 Tags: Space
Fragments of rocks and dust brought back by China’s Chang’e-5 moon mission are undergoing study and data will soon be given.
Researchers are using geological mapping to identify exotic components in the sample brought back by the mission.
The Change’e-5 mission had landed on the far side of the moon, which has not yet been visited by any country’s mission.
The samples brought back are younger than the samples that were brought by NASA and ROSCOSMOS missions about 50 years back.
Out of the total sample brought back, about 50% belongs to the area surrounding the landing site. These have been named ‘mare basalts’.
The volcanic rocks are part of the dark grey areas that were formed due to the ancient eruptions of lava. About 10% of sample has exotic composition.
The samples contain chemical signals of space rocks that have hit the Moon’s surface. They have managed to identify beads of rapidly cooled glassy material.
Extinct volcanic vents known as ‘Rima Mairan’ and ‘Rima Sharp’ were responsible for formation of volcanic beads.
Samples from rocks of young geological age have also been classified. These rock samples are not available on the near-side of the moon.
