Could it be possible to drill through the center of the moon to the other side and have two research stations over each hole

could you use it to explore gravity at the the center

using retrievable probes fitted with sensors

Yeah piece of piss just shuttle one of our tunnel diggers up there and point it in the right direction.

when possible

I dont mean straight away

there is plenty of time

maybe 3D print the tunnel digger from gathered materials on the moon

Drone would find the materials and process them from the 3D printer

no moving giant structures in space

that needs a but of time to work out

Drones would find the materials and process them for the 3D printer.

I was only being enthusiastic not sarcastic.

On one hand, it would be hard to say that we will never have the technology or resources to do this.

On the other hand, it is clear that we do not have the technology or resources to do this now and are not likely to in our life times. The deepest hole we’ve drilled on earth is some 12 km deep.

The centre of the moon has a temperature of about 1500 deg C. It is soft, like the earth’s mantle. The pressure would be in the tens of billions of pascals. If you just “drilled” it would quickly fill in, so you would need to emplace a casing capable of withstanding these temperatures and pressures.

party poo-person!

A goal for the space station would be to be able to 3D print habitual modules up in space

and recycle materials from old modules damaged by space debris, straight into the 3D printer to create New Modules

Another Space station project could be Nano robots which could fix holes and cracks

they could be 3D printed then go into a hole or crack and stay there to become part of the material

they all kind of lock together

Well, you’d need a drill bit capable of drilling at temperatures of 1,327 to 1,427 °C. Remember that lava is a liquid at temperatures from 700 to 1,200 °C so the rock in the centre of the Moon is either highly deformable or actually liquid. Drill bits on Earth have run into serious difficulties at temperatures between 240 and 300 °C.

An easier alternative is to track satellites in orbit around the Moon. Then interpret the data in the same way that a CT scan is interpreted to find what’s going on in the interior of the brain.

The pair of GRAIL satellites have made a start on that.

Pretty and informative pictures mapping the Moon’s gravity field are here.

I’m highly skeptical that we know the temperature at the centre of the Moon to anything like that level of precision.

I think it’s an interesting question though:

All things considered, which would be easier: a hole through the middle of the Earth, or through the middle of the Moon?

I’m going to say through the moon, just because we don’t have any materials that will be solid at the temperatures at the centre of the Earth.

Tungsten or maybe tungsten carbide will do that easily.

Moon, I’d say. For several reasons, even taking account the difficulty of getting the drill there.

Would the regolith layer pose any problems ?

Would the regolith layer pose any problems ?

maybe. it is really “sticky” due to electrostatics. this could cause a problem with moving parts.

What if super cooling was used? With superconducting materials?

Otherwise a smaller moon then

doesn’t have to be a big moon, but a big moon would be good

A moon with a magnetic field would be even better

Would any large asteroids have enough gravity for experimentation?

and it doesn’t have to be a permanent fixture but that would be good too

what do you hope to achieve with this experiment?

exploration of gravity in moons

If everything could be done from satellites then there is no need for it

I was thinking only if there were possible gravity / magnetic field experiments one could do in the middle of a moon

That was a super delayed double post…
