A report on the status and early results of the ESA astrometry mission Hipparcos, launched in 1989, which aims at the construction of a uniquely accurate and uniform catalog of positions, parallaxes, proper motions and photometric information for 118,000 preselected program stars, is presented. Additional data for up to a million stars will be obtained by the Tycho part of the mission. The first results of the lengthy catalog construction process are available in the three data reduction consortia. The early (and provisional) star positions and distance estimates give a dramatic indication of the outstanding scientifc potential of the mission. In spite of the many difficulties and losses caused by a faulty orbit it is now expected that the nominal goal of 2 milliarcsec accuracy (for typical stars) will be reached around 1993.0 and even surpassed for a longer mission.
