Roger Bonnet (ESA Director of Science from 1983 to 2001) speaks at the International Hipparcos Press Conference, 11 April 1988.

At the press conference, Reimar Lüst (ESA Director General, 1984-1990) received the Hipparcos Input Catalogue on behalf of ESA, in the presence of members of the Hipparcos science community and ESA Hipparcos team members. The Hipparcos Input Catalogue formed the mission's observing programme: it contained over 100 000 target stars that Hipparcos would monitor to obtain their astrometric properties.
