more ? or less ?

did the guys walking on the moon have to pressurize the space suits? or
de-pressurize.

and do the pressures change during elevation changes.( if they were to
get to the top of a moon mountain)

i know (now) that we, from our perspective only see one "side" of the
moon.
does the other "side" get sun light.

could we place an object in a static orbit, at a much lower altitude
than here on earth, because of the gravitation differences ?

does any body know of a web site that offers a "moon cam"

and finally

whats the temp on the sun lit side, and does that figure change with
altitude ?

thanks again

There is essentially no atmosphere on the Moon, so yes, they
had to pressurize their suits. No atmosphere also means no
pressure change with altitude.

Of course. The Moon rotates on its axis in the same period
that it revolves around the Earth. During what we call a
new moon, the back side is fully lit.

No. The rotation period of the Moon is on the order of a month.
The radius of a stationary orbit would be about 90,000km. Any
satellite at that distance would suffer from perturbations by
the Earth's gravity and would soon leave its orbit.

There's no atmosphere so there's no "air" temperature. But
anything in sunshine will be heated by the incident sunlight.
The solar flux at the Moon is essentially the same as for the
Earth, about 1370 watts per square meter. Bodies in sunlight
will warm up until their radiated heat matches this influx.
The amount of heat absorbed will depend upon the reflectivity
(albedo) of the object.

When we see a new moon then it's a full moon on the dark side. Yes it gets
light.

I haven't thought it through fully, but it seems to me that there may be
some gravitationally neutral points where the earth and moons gravity fields
cancel. A bit like the Earth-Sun Lagrange points. If the neutral locations
do exist they may not be particularly stable, not least due to the sun's
influence.
