According to the China Space Agency, on January 4, the moonless Chinese spacecraft, landing on the moon, faced the coldest night than expected.
The moon's temperature dropped to 19 degrees Celsius. During the night the temperature on the moon decreased. Previous missions are less than what the US vehicles recorded, because earlier missions found the moon on the hidden part of the moon.
The agency predicted the difference in temperature difference between the unexpected nature of the earth and the hidden side.
