There may be a secret cave hidden on the Moon. NASA wants to probe it. The place is called the Marius Hills Pit.
What the Pit Is
The Marius Hills Pit is described as a deep skylight. A skylight, in this sense, is an opening in the surface. Below that opening, there may be much more than a simple hole.
Reports based on NASA mission concept reports say the pit may open into a vast underground lava cave. A lava cave is a cave formed by lava. If this one is there, it would be a large underground space, hidden under the Moon's surface.
That is why the word secret fits this story in a simple way. The cave, if it is as described, is not on the open surface where anyone can see it. It is underground, reached through the pit.
What NASA Wants to Do
NASA wants to probe the Marius Hills Pit. To probe means to explore and check it closely. The caption for this video puts it in the same simple way: NASA plans to explore this mysterious lunar pit.
This comes from NASA mission concept reports. A mission concept is a planned idea for a mission. It is not, in these reports, a finished mission with a result already in hand. It is the plan to go and look.
Only by probing the pit can NASA check what is really below it, and whether the cave is really there in the vast form the reports suggest.
Why a Cave Matters for Astronauts
The reports give one clear reason why this cave matters. It could one day shelter astronauts.
A shelter is a safe place to stay. On the Moon, astronauts will need shelter. An underground cave, if it can be reached and used, could be that kind of place, under the surface instead of on it.
That idea is still for the future. The word is could, and the time is one day. First, the pit must be explored. Then the cave must be understood.
For now, the story is simple and exciting. A deep pit on the Moon may be a door to a vast hidden cave, NASA wants to explore it, and that cave could one day be a shelter for the astronauts who go there.
