Chang’e-5 probe:


Context:

Chinese spacecraft carrying rocks and soil from the moon has begun its journey back to Earth, putting China on course to become the first country to successfully retrieve lunar samples since the 1970s.

What Next?

A successful landing in Inner Mongolia would make China only the third country to have retrieved lunar samples after the United States and the Soviet Union.

The plan was to collect 2 kg (4.4 lbs) of samples, although it has not been disclosed how much was actually gathered.

Background:

The Chang’e-5 was launched on Nov. 24 and a lander vehicle touched down on the moon on Dec. 1. The mission was expected to take around 23 days in total.

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.

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 four parts: an orbiter, a returner, an ascender and a lander.

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

  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.
