This is John Batchel, a conversation with colleague Bob Zimmerman about an experiment on the surface of the moon by Blue Ghost, a privately launched lander.

The experiment, can you clean off the dirt and the dust that's accumulated on the moon for billions of years that has no moisture content whatsoever.

It's extremely sharp

and goes everywhere and sticks to everything.

The astronauts, Bob will explain, had trouble.

Well, there may be an answer.

Here's Bob Zimmerman to introduce

what the moon colonies will need if it works.

Very exciting. More of this tonight.

Just without question that every single operation on the moon is going to require what we on Earth call mudroom.

Your airlock, you're going to probably need two airlocks, one as your mudroom to get rid of all the, to take off all the dusty stuff,

and then you go into a second airlock where they can then clean you off with this kind of

a technology. So when you enter the habitat, you're not bringing the dust with you. It's a problem

that got to solve. Bob, do I remember correctly that that dust is toxic to human beings?

Well, it is in its abrasive nature.

It's inert.

It won't poison you or anything, but it's extremely abrasive, sharp.

Remember, it has no erosion products.

Things go on on the moon to soften its shape.

These are not little steers.

These are sharp, jagged like glass, tiny, though.

So yes, if you get it in your system, it could do you harm.
