For the 1st time, scientists confirm the moon has a solid iron 'heart' just like Earth
Live Science ^ | Joanna Thompson

The first hints that the moon had an Earth-like interior came from NASA's Apollo missions. Data gathered by the lunar landers' instruments suggested that the celestial body was differentiated — or layered with denser material at the center and less dense material nearer the surface — as opposed to uniform rock all the way through. Apollo astronauts even left seismometers on the moon, which later revealed that it experiences moonquakes...

However, scientists were only recently able to sort through the massive data sets from the Apollo missions and other lunar probes to get a clearer picture of the moon's insides.

Using a detailed computer model built on geological data from the Apollo program and NASA's GRAIL mission — which used a pair of probes to monitor the moon's gravitational field for more than a year — the researchers determined that the inner core is about 310 miles (500 km) in diameter, or only 15% of the Moon's width.

Only recently looked at the Apollo data? The last Apollo mission was in 1972.

Also, the Moon is in danger of Global Warming from Lunar Lander rocket fuel exhaust. It will probably be destroyed in just 8 years unless we sink billions of dollars into designing electrically powered spacecraft.

Nope. The moon is hollow. An alien from the Dark Side told me so.

Goes along with the dozens of boxes and file cabinets of Apollo mission photos destroyed to make room for other things. Or the still unexamined Apollo rocks - many of which were just handed out as souvenirs to random people.

I don’t know. Maybe the data wasn’t much use without the kind of computers we have today. Or something.

Scientists and/or pundits said way back that when they crashed (on purpose) objects into the surface that it “rang like a bell” therefore it had to be hollow.....

Why did the lunar rover have a compass?

Oddly, so is the Earth. The internet has a all kinds of videos on that topic. The entrance is on Antarctica. However, further research showed that the earth is flat and Antarctica is just a boarder preventing the seas from flowing off the edges. I get confused about the reptilian humanoids. Did they come from space or do they live at the center of the Earth, maybe both.

Solid is the wrong word for molten.

It goes back further than that. From the article:

In 2011, research from NASA suggested that the moon's outer core was made of fluid iron, and created a distinct partially melted layer where it met the mantle. The study also hinted that the moon might have an iron-based inner core. Now, the new study has confirmed that this dense inner core exists.

Also:

Based on recent calculations, researchers have been able to pin down that the temperature of the Moon right where the core meets the mantle ranges between 2,300 and 2,680 degrees Fahrenheit (1,300 and 1,470 C).

We ain't digging that metal out just yet!

The computers of yesteryear were just as functional as the ones we have today, just slower. On the other hand, they didn’t need the massive resources required just for the operating system as do the modern ones. Those old number crunchers had enormous integers and some had 128 bit floating point.

Throw guided chunks of iron into the gravity well. Free Moon Alliance!
