# Status report on the EUSO project at the end of phase A

Abstract : EUSO is 2.5 m diameter telescope to be installed on the International Space Station (ISS) to observe from above ($\sim$400 km altitude), very high energy ($10^10-21$eV) cosmic rays by detecting the UV light generated by the billions of electrons in the shower ionizing the atmosphere nitrogen. The European and Japanese parts of the collaboration depend on ESA for the mission and the results of phase A should be examined in November 2003.The US part of the collaboration has already been approved for phase B by NASA, to the condition of an OK by ESA.
