Query: The WAXS/WFXT Mission   I present the science goals and give a brief summary of the Wide Angle X-ray
survey with a Wide Field X-ray Telescope (WAXS/WFXT) mission proposal (Phase A)
which will be submitted to the Italian Space Agency (ASI) following the call
for proposal under the Small Satellite program. The text points out the
uniqueness of the mission for the study of the evolution of clusters of
galaxies and of the Large-Scale Structure at large redshifts and for the study
of the Milky Way. I present, furthermore, the successful result of the
metrology of the first wide field X-ray optics ever made.
