A Japanese spacecraft has discovered a large cave on the moon. It is thought that astronauts traveling to the moon in the future will be able to stay in this cave.

The United States has sent astronauts to the moon six times since 1969, and they have had to stay in their spacecraft. It was possible to stay in the spaceship like this because only two people went at a time.

Besides, they didn't stay long on the moon. In 1972, the Apollo 17 crew stayed on the moon for a maximum of 75 hours.

Future astronauts will spend many days on the moon. They would have to make underground dwellings and stay there. Stay in the now discovered cave until such dwellings are established.

Establishing settlements on the surface of the Moon, i.e. in the open, is probably impossible. This is due to the conditions on the Moon.

Lunar day is 14 days according to Earth reckoning. Night is similarly 14 days. The peak daytime temperature on the Moon is about 106 degrees (Celsius). At night it will be as cold as minus 173 degrees (Celsius). This is due to the fact that the Moon has no atmosphere.

If you stay on the moon for many days, you have to make dwellings under the ground. Or to go and land in the polar regions of the Moon is already the situation.

It is against this backdrop that a Japanese spacecraft has discovered a cave on the moon.

A cave is naturally formed on the moon. Volcanoes were active on the moon about 300 million years ago. Volcanoes still spew fire on Earth. But volcanoes on the moon have erupted at some point.

Lava solidifies on Earth.

The lava that erupts through the mouth of the earth thickens more and more and the volcano gradually rises in the form of a cone. Not so on the moon. On the Moon, the fiery fluid is very diluted. So spread over a larger area.

A Japanese spacecraft was sent to the moon in 2007. It spent two years exploring the moon extensively. The information sent by Kaguya has been investigated and the details have only now been released

Apart from these, there are such volcanic tunnels not only on the Moon but also on Earth. They are found in the states of Idaho and Oregon in the United States. Volcanic tunnels are also found in South Korea, Spain's Canary Islands, Portugal, Kenya and Iceland. The volcanic tunnel on the island of Hawaii is 65 kilometers long.

Volcanic tunnels have also been discovered on Mars
