first lunar-ground transfer incident
At 9:54 on December 12, Beijing time, the much-anticipated Chang'e 5 after 6 days of waiting, finally realized 's first lunar-ground transfer incident , starting from The near circular orbit is transformed into an elliptical orbit with a height of about 200 kilometers at the near moon point.
's first lunar-to-ground transfer incident display picture
collected on the moon 2000 grams of samples, has been "collected" . After this incident, the orbiter and returner carrying these samples will select the appropriate time and opportunity to carry out the second lunar-to-earth transfer incident to , so as to get rid of the lunar-earth gravity and enter the lunar-earth transfer orbit and fly to the earth. It is expected to land at 1:26 on December 17th, Beijing time , in Inner Mongolia Siziwangqi

What is the value of this "moon express"? The success of
's lunar exploration is a huge improvement of our country's , and the samples brought back also help our scientists' research.
Indeed, at this time, the resources of the moon are not available to us. But in the long run, this will be an important step in our deep space exploration.
The soil of the moon
is known to be scarce on the earth and there are very considerable reserves on the moon helium-3, which is the raw material for nuclear fusion , and is also an important energy source in the future. Compared with the current thermal power, hydropower, wind power, solar, nuclear power Wait, mastering controllable nuclear fusion will be the ideal energy for in the future. And a lot of raw materials are on the moon.
Imagination of a future lunar base
believes that after successful use of helium-3 in the near future , we can establish a base on the moon, which is the outpost of our earth exploration, and the energy for deep space exploration spacecraft can be on the moon You can get supplies and the energy of the earth can be satisfied. So exploring the moon is also an indispensable step for our other explorations.
