The temperature difference between day and night on the moon is huge. How do astronauts land on the moon?

On July 21, 1969, the US Apollo 11 spacecraft successfully landed on the moon with three astronauts on board. The moon is the closest planet to our earth and the first and only planet that people have landed on. Although the moon is close to the earth, the environment is very different from that of the earth.

One day and night on the moon is equivalent to 29.5 days and nights on Earth. There is no atmosphere on the moon, so the temperature difference between day and night is very large. The highest temperature during the day can reach 127 degrees Celsius, and the lowest at night is minus 183 degrees Celsius. The maximum temperature difference on the moon can reach more than 300 degrees Celsius, but whether it is the temperature during the day or at night, it is impossible for us to adapt. So, how did astronauts overcome such a harsh environment and successfully land on the moon?

We all know that the temperature is unbearable for humans, whether it is daytime or nighttime, so the best option is to land in the daytime, so that you can also get the solar energy shining on the moon, making the equipment run more efficiently. NASA landed on the moon in the daytime. According to reports, the temperature of the moon was about 70-80 degrees Celsius when it landed.

Moreover, NASA's technology was very advanced at the time, and the astronauts' helmets were carefully designed. The helmets could not only effectively prevent damage from ultraviolet rays, but also prevent damage to the astronauts' bodies caused by temperature differences.

The reason why the lives of astronauts can be guaranteed is all thanks to the space suits. The space suits are airtight and automatically adjust the temperature to ensure the safety of astronauts.

In a vacuum environment, the nitrogen in the human blood will be converted into gas, causing the volume to expand. The pressurized airtight space suit will prevent the human body from having accidents due to the huge pressure difference on the moon. The space suit also has multiple functions such as protection against vacuum and ultraviolet radiation. Modern new extravehicular space suits have a liquid cooling structure, which allows astronauts to go out of the cabin or explore the moon.
