Re: t.Pluto conjunct n.Mars
No, it's not conjunct yet, nor will it be this year. However, you should see "the writing on the wall" as to what it WILL represent.
By the way, whenever you mention your Sun, you should represent it as "Sun-Uranus" as there will never be a time that either Sun or Uranus will act or be acted upon alone.
They are what is known as "cazimi" - only 15 minutes apart. This can work for or against you. You may want to read more about this phenomenon.
The Pluto that squares your Sun-Uranus as it conjuncts Mars will act, as it always does, to irrevocably change you. It is the aspect or transit of "metamorphosis." If you have, in the past, been your own worst enemy in some area of your life, or if your Mars has worked against you, or not worked at all, Pluto will change that in some way - change it forever. This can be a very difficult transit... difficult and long lasting, because first Pluto will Square your Sun-Uranus, then your Mercury and finally your Pluto. This will take several years.
Without the grace of being given Venus at the beginning of Virgo, and Moon and Saturn at the beginning of Taurus, this could have been tragic. BUT you lucked out.... and therefore, this year Pluto will trine your Moon in Taurus before it gets to the square of Sun-Uranus. Pluto will also trine Venus at the same time it squares your Sun-Uranus..... again, a blessing.
Nevertheless, there will be many rough patches and you will have to learn to examine your own values, partnership values, philosophy, beliefs, goals and ethics, and continue to take a personal inventory as time goes on. These transits to come are NOT for sissies. They will change you, what you are attracted to, the way you think, and your goals.
