China’s Chang’e-5 Lunar Mission

Subject – Science and Tech

Context – Lunar samples brought by Chinese mission studied

Concept –

  • Remnants of solidified lava brought back by a Chinese lunar mission were 1 billion years younger than material acquired by other missions decades ago, according to an article in Science, suggesting the moon cooled down later than thought.
  • Samples brought back by U.S. and Soviet missions were more than 2.9 billion years old. The samples acquired on China’s Chang’e¬5 mission late last year were around 1.96 billion years old suggesting volcanic activity persisted longer than believed.
  • Last December, the uncrewed Chinese probe touched down on a previously unvisited part of a massive lava plain, the OceanusProcellarum or “Oceans of Storms,” bringing back lunar samples.
  • One of the main objectives of Chang’e-5, was to find out how long the moon remained volcanically active.
  • “The Oceanus Procellarum region of the Moon is characterised by high concentrations of potassium, thorium, and uranium, elements that generate heat through long-lived radioactive decay and may have sustained prolonged magmatic activity on the nearside of the Moon,” wrote the article’s authors.
  • The article said the heat source for the magmatic activity might also be the so called “tidal heating,” or heat generated by the gravitational tug and pull of the Earth.
  • The Chang’e¬5 mission made China the third country to have retrieved lunar samples, after the United States and the Soviet Union, which launched the last successful mission to acquire material from the moon.
