  Reasons for the current interest in cosmic rays above 10^19 eV are described.
The latest results on the energy spectrum, arrival direction distribution and
mass composition of cosmic rays are reviewed, including data that were reported
after the meeting in Blois in June 2001. The enigma set by the existence of
ultra high-energy cosmic rays remains. Ideas proposed to explain it are
discussed and progress with the construction of the Pierre Auger Observatory is
outlined.
