Chang’e-5 probe: China recently presented the early-stage findings of Chang’e-5 probe, which uses geological mapping to link ‘exotic’ fragments in the collected samples to features near the landing site.

Background:

  • On December 16, 2020, China’s Chang’e-5 lunar mission delivered to Earth nearly 2 kg of rocky fragments and dust from the Moon.
  • The Chang’e-5 landed on the western edge of the nearside of the Moon in the Northern Oceanus Procellarum also known as the Ocean of Storms, on the near side of the moon on December 1.
  • This is one of the youngest geological areas of the Moon with an age of roughly two billion years.
  • The materials scraped from the surface comprise a loose soil that results from the fragmentation and powdering of lunar rocks over billions of years due to impacts of various sizes.
  • Scientists carried out the storage, analysis and research of the country’s first samples collected from the extra-terrestrial object.

The Findings:

According to the Europlanet Society, the studies presented by Qian are as follows:

  • 90% of the materials collected by Chang’e-5 likely derive from the landing site and its immediate surroundings, which are of a type termed ‘mare basalts’.
  • These volcanic rocks are visible to us as the darker grey areas that spilled over much of the nearside of the Moon as ancient eruptions of lava.
  • Yet 10% percent of the fragments have distinctly different, ‘exotic’ chemical compositions.
  • The distinct 10% fragments may preserve records of other parts of the lunar surface as well as hints of the types of space rocks that have impacted the Moon’s surface.

About Chang’e-5 probe:

  • It is an unmanned spacecraft by China.
  • The probe is named after the mythical Chinese moon goddess.
  • The rocket comprises of the four following parts:
  • An orbiter,
  • A returner,
  • An ascender
  • A lander

The Chang’e-5 mission is expected to realize four “firsts” in China’s space history. They are as follow:

  1. The first time for a probe to take off from the surface of the Moon.
  2. The first time to automatically sample the lunar surface.
  3. The first time to conduct unmanned rendezvous and docking in lunar orbit.
  4. The first time to return to Earth with lunar soil samples in escape velocity.

The objective of the mission was to bring back lunar rocks, the first attempt by any nation to retrieve samples from the moon in four decades.
