according to the sheet Space, The CNSA’s goal is to observe objects that were born within the first few hundred million years after (13.8 billion years ago) the event that gave birth to the universe.
They plan to achieve this with Hongmeng, a state-of-the-art constellation of solar-powered parent and eight child satellites, which is expected to orbit the Moon by 2026.

Hongmeng project. also called project “Explore the sky with the longest wavelength”with a view optimized not only by its superior observation power, but also by its extremely favorable special position.
A telescope on or in orbit around Earth’s natural satellite will help scientists see cosmic radiation in an electromagnetic spectrum that cannot be studied from the ground: radio waves more than 10m long, c ie frequencies below 30 MHz.
this number – “the last electromagnetic window of the universe” will provide information on “Dark Times” – is the period of the first hundreds of millions of years of the universe, when the young universe was filled with a seemingly impenetrable hydrogen fog.
However, atomic hydrogen itself emits a type of signal called . “Line 21cm”used to be used to observe things up close.
Observation is difficult because of the redshift effect created by “elongation” Electromagnetic radiation from distant objects, so it reaches the earth with too long a wavelength, making other telescopes unavailable. “see” All right.
For “Through time” When it comes to the early universe, China’s observing system also uses the same fundamental laws of physics as other telescopes such as NASA’s James Webb, Hubble: every image we see has a certain time lag. , is the time it takes for light to bounce from that object to Join Us.
So the image we see of an object billions of light-years away is also the image billions of years ago. With just enough observations, telescopes could reach the early universe over 13 billion years ago.
Observational records of the oldest and most distant worlds in the universe currently belong to James Webb, but there are still several hundred million years to the time of the Big Bang.
