报告摘要：
Venus Express is the first European mission to planet Venus. The mission aims at a comprehensive investigation of Venus atmosphere and plasma environment and will address some important aspects of the surface physics from orbit. In particular, Venus Express focuses on the structure, composition, and dynamics of the Venus atmosphere, escape processes and interaction of the atmosphere with the solar wind and so to provide answers to the many questions that still remain unanswered in these fields. Venus Express will enable a breakthrough in Venus science after a long period of silence since the period of intense exploration in the 1970s and the 1980s. The spacecraft was launched on 9 November 2005 from Baikonur (Kazakhstan) by the Russian Soyuz-Fregat launcher and arrived to Venus on 11 April 2006. In this talk we present the initial observations by Venus Express and we address the new results on the solar wind interaction with Venus.
