[quote]Outside of 'Lucid Dreaming' ( which I have my own theories about that don't involve Astral travel), I've never gone anywhere on the 'astral plane'.[/quote]
Be interested to hear them.
[quote]1) WHAT is it?[/quote]
Well, I went to have a think about this because I was curious about the origins of the word - I rather think, but may be wrong, that the term 'astral' derives from 1600s religion-accommodates-science theology of heaven and earth having a meeting point which joins earth to Heaven - in which the human spirit lives, as do ghosts, spectres and all things phenomenal. It's not a solely Christian perspective and can be found in things like the mirror concept of Haitian Vodoun and Spiritualism. Not surprising with the latter as Spiritualism was very much a bi-product of the aforementioned age of reason and science.
The dictionary seems to say:
–adjective
1. pertaining to or proceeding from the stars; stellar; star-shaped.
2. Biology. pertaining to, consisting of, or resembling an aster; having a discoid, radiate flower head.
3. Theosophy. noting a supersensible substance pervading all space and forming the substance of a second body (astral body) belonging to each individual. It accompanies the individual through life, is able to leave the human body at will, and survives the individual after death.
I think the third definition is the one we're particularly concerned with - I have to admit to not knowing it was Theosophic in origin.
My old buddy EtymologyOnline cites the origin simply as:
astral
1605, from L.L. astralis, from L. astrum "star," from Gk. astron.
Making the third definition very much one of spiritual lexicon.
Wiki explains that:
"Astral projection (or astral travel) is an esoteric interpretation of a type of out-of-body experience that assumes the existence of an "astral body" separate from the physical body and capable of travelling outside it.[1] Astral projection is experienced as being "out of the body".[2] Unlike dreaming or near death experiences, astral projection is practiced deliberately."
Which rather backs up the 1600s explanation that always stuck in my mind: in order to have a body existing in the 'spiritual realms' (AKA 'astral') then there needs to exist a sphere or buffer between being completely detached of your body/dead and being trapped within your body - the astral. Most cultures - if not all - seem to agree this theory in some form or another. I suppose one of the better illustrative examples of the 'astral' are auras - when you can see the energy of something that is not physically there but not non-existent. The 'in-between'. A layer of energy that is neither physically a solid nor purely imaginary.
[quote]2) WHERE is it? ( i.e. - an actual separate plane outside ourselves, or confined within our 'mind' or both?)[/quote]
Well, according to the Christian conceptualisation it is the bit that attaches us, the earthly presence, to 'Heaven'. The bit between here and there

In an occult sense perhaps we'd describe the 'earthly' to be us in day-to-day mode/solid physicality and at the extreme end 'death' - the 'other side of the mirror'. So it is the mirror, if you like.
I imagine the levels of astral reality that so many cultures document depends as to whether you're standing closer to the earthly side or the 'beyond' side.
As for confined within our minds, there was a brilliant quote in
DreamFlesh to the effect that everything was once animism, but we analysed and critiqued it so much in order that we should understand that we made it thought and pushed it deep within us. Now we're all struggling to bring it back out of our heads again

I think whether it's inside or outside of us is ultimately irrelevant 1. to what it is and 2. to what it does. As all is within itself anyway.
[quote]3) Does one go to the same place every time? Do you recognize it as the same place every time and so are able to negotiate the way?[/quote]
Oh how many ways of answering that are there!
If you go to Totness ten times in a year, are you always going to the same place every time? Bar geography

Yes, I think from reading certain accounts such as the ayahuasca experience and subsequent conversation with the blind shaman in Harner's Way of the Shaman - yes, there are characters and places which are relatively constant in the same way Totness is constant give or take the wind, rain, sun, snow, people you meet, new buildings and different parking space. I think we know so very little of it it's easy to get very lost and not to recognise your surroundings - as with any big city you visit for a day or continent you fly over in a plane then try and navigate by map.
There are certainly things we can negotiate - as with dream mapping and lucid dreams. There are many things, as with day-to-day life, we cannot control, navigate or understand. We spend more time in day-to-day so the rules seem clearer to us - it's home turf

[quote]4) HOW do you get 'on it'?[/quote]
Entheogens; dreaming; meditation; concerted effort; trance work
[quote]5) WHY do you go?[quote]
Pure curiosity; a belief that it might be useful; pushing the boundaries; validating what we've been told or read about; fascination; human nature to do so; because.
[quote]6) In what way is it useful to you?[/quote]
Probably in whatever way we are useful to it. Would it exist without us? Who knows, our conceptualisation of it wouldn't if we didn't - so to some extend our perception of it gives it existence - in a wonderfully existential way.
It's useful because it is there - it's a dimension in which to exist. In the same way 'existence' is useful. We need it, it's a necessity to our being even if we don't know why.

UPGs?
