The Solar Wind Nine Conference was the ninth in the series of solar wind conferences established in 1964 by Dr. Marcia Neugebauer to provide a forum for the interaction between solar physicists and space physicists interested in the origin and evolution of the solar wind. One of the scientific goals of the conference was to reflect the importance of the synergistic interaction between theory, numerical modeling and simulations, in situ measurements and remote sensing observations, in the exploration of the solar wind. Indeed, the opportunity provided by the many concurrent missions Ulysses, Yohkoh, SOHO, TRACE, SPARTAN, WIND, and ACE, which probe the Sun and interplanetary space from different vantage points, provided very rich material for the contributions. The presentations included invited reviews and contributed talks as well as poster presentations. This conference took place almost 40 years after Parkers prediction of the existence of the solar wind.
