The X-ray band from 0.1 to 10 KeV is rich in discrete and continuum spectral features, and comprises emission and absorption K-shell spectra of carbon through nickel, L-shell spectra from neon through nickel, and M-shell spectra from iron and nickel. The high spectral resolution of current satellite missions such as the Chandra X-ray Observatory and the X-ray Multi-Mirror Mission are opening the X-ray band to scientific research in an unprecedented fashion. However, the successful interpretation of the spectra requires large amounts of atomic data, as well as detailed account of all microphysical processes that dictate X-ray spectral formation. We report on the main conclusions of the workshop on "Atomic Data Needs for X-ray Astronomy" held in December 1999 at the NASA Goddard Space Flight Center. Next, we present an update on the currently available atomic data for energy levels, wavelengths, radiative transition probabilities, electron impact excitation rates, photoionization cross sections, recombination rate coefficients, electron impact ionization rates, charge exchange rate coefficients, and fluorescence and Auger yields. Finally we evaluate the state of data collection, Web-interfaced archives such as TIPTOPBASE, and the most urgently needed data in terms of quality and completeness for the present and upcoming observational satellites.
