The surface pressure of the moon is 10E-7 Pa.
Or in kPa 10E-10. (0.0000000001)
This pressure is so small because the moon has virtually no atmosphere. Therefore very little pressure. (This can be contrasted to the average sea-level pressure of Earth at 101325 Pa or 101.325 kPa)
I would imagine it drops, because there is less gravity.
Water on the surface of the moon will rapidly turn to water vapor as there is no atmospheric pressure on the moon. The vapor will then escape the moon's gravity which is much weaker than the gravity on Earth.
You can stand on the moon surface if you can get there
Antarctica's surface is similar to that of the moon in that it is rocky.
The message is that it's really cold there. As the moon has no atmosphere, there is no atmospheric pressure. Atmospheric pressure has a pronounced effect on the boiling point of water. If the water does exist on the moon and it does lie on the surface in a "no-pressure" situation, it would have to be very cold to remain there under the circumstances.

Low surface pressure and a new moon are the main reasons
Water on the surface of the moon will rapidly turn to water vapor as there is no atmospheric pressure on the moon. The vapor will then escape the moon's gravity which is much weaker than the gravity on Earth.

No
The moon is much smaller than the Earth and has a weaker gravitational field. As a result, gas on the lunar surface leaks away into space, rather than forming an atmosphere. And with no atmosphere, there can be no barometric pressure.
They touched some lunar samples with bare hands, but not the moon itself. They did walk on the moon's surface, but they were in full pressure suits the entire time they were outside the Lunar Module.

The moon has no air pressure because the moon has no air.
The moon's surface is regolith (ground up rock).
The outer surface of the moon is called the crust.
