Huge Cave Found under Surface of Moon (News)

China, Russia, India and the United States have made successful unmanned moon landings, but the U.S. is the only country to have put humans on the lunar surface.

The safest place to seek shelter is the inside of an intact lava tube, according to the study.

Scientists with Japan's space agency have announced they have discovered what appears to be a large cave on the surface of the moon-a potential spot for astronauts to set up an exploratory base.

As experts noted, the cave appeared about 3.5 billion years ago by volcanic activity.

The underground caves were formed when lava tubes, which form the outer part of flowing lava, cooled into hard layers.

The lunar orbiter Kaguya, also known as Selene, discovered the tube-shaped, 50km cave by using its radar sounder system that examines underground structures.

Research presented at the European Planetary Science Congress (EPSC) last month in Riga, Latvia, found that lava tubes on the moon may be big enough to house entire cities. JAXA's moon probe "SELENE". This data can show areas of mass deficits - areas on the moon's surface where mass is reduced or missing.

The cave, located in an area called the Marius Hills, could be a candidate site for a future lunar exploration base because temperatures inside are stable and effects of radiation are limited, according to the team. Scientists fired multiple radar bursts into the suspected lava tubes, and what they got back was a two-part echo indicating the interior of the pit has a floor and a ceiling.

The existence of lava tubes on the moon has been speculated in the past, but this combination of radar and gravity data provides the clearest picture of what they look like and how big they are yet.

Jaxa recently announced that it aimed to put a Japanese astronaut on the moon for the first time by around 2030, most likely as part of an worldwide mission.

That was the first time the JAXA space agency had said it planned to send an astronaut beyond the International Space Station.

"We will return American astronauts to the moon, not only to leave behind footprints and flags, but to build the foundation we need to send Americans to Mars and beyond", Pence said.
