Pluto was not disqualified in space. It was reclassed into a more specific category: dwarf planet.
space probes have crossed Pluto's orbit, but never have visited the planet because Pluto was not in alignment with the flight path of the space probes.
No space craft or person has landed on pluto.
No, there haven't been any space probes to land on Pluto physically, but the Hubble Space Telescope has been, somewhat, close to be able to take pictures of Pluto.
The Preface from the Pluto Files is a book. This book is about space.
Pluto is no longer a planet (though it is now a dwarf planet) because :It wasn't big enough to be considered a planet (less massive than Eris)Pluto's orbit was inclined too much from the ecliptic and has a large eccentricityPluto is a member of the Kuiper belt
Currently, there are no space mission that have involved the landing on Pluto. New Horizons; will be doing a fly-by of Pluto in the near future.It will be closest to Pluto on July 14, 2015.

No Space Probes have currently visited Pluto. However NASA launched a space probe called New Horizons to take pictures of pluto and to discover more objects in the Kuiper Belt. New Horizons is expected to arrive at Pluto in July 2015.
The only space probe to visit Pluto was the New Horizons spacecraft. It took 9 years to get there.
No. The notion of Neptune being disqualified as a planet is not even being discussed. The concerns that apply to Pluto do not apply to Neptune.
As a planet, I assume. This should have happened quite a while ago; it turns out that Pluto is much smaller than initially believed. (However, the current official definition of a planet is not directly related to its size or mass.)
