How much did the "souvenir" brought back by the six girls weigh? Some netizens said, "Two kilograms, high". [Like]
Today, the weight of the "sample" brought back by the Chang'e-6 returner will be announced. Let's look forward to it......
First of all, it is clear that the capacity of the container is fixed, standard container, 2 kg. Full!
In this sampling on the back of the moon, the sixth girl, like the fifth girl, encountered the same problem, that is, the drilling depth was about 1 meter. Because of the different degrees of stones, the drill bit could not reach deeper places.
1. Because it is an unmanned drill, it cannot dissipate heat;
2. It is also impossible to temporarily change the sampling point;
3. The current drill bit cannot hit stones.
As we all know, the friction between the drill bit and the stone will produce high temperatures, and the drill bit will be burned off after the temperature is very high. In ground operations, water is poured to relieve high temperature friction. However, on the moon, there is no way to cool down at all.
However, even so, it does not affect the "digging of the soil" and it is enough.
Originally, it was planned that the six girls needed to dig 10 shovels, but by the time they reached 7 shovels, they were almost full. The final quantity is 8 shovels, which is commonly referred to as a free shovel. In weight, it is definitely "tall".
The fifth girl once shoveled 12 shovels, and although the sixth girl had 8 shovels, the last shovel was actually to complete the "medium".
How heavy the "sample" on the back of the moon is, we'll see it today......
