The observation of Lyman-alpha emission from galaxies in the epoch of reionization (6 < z < 10) provides the best opportunity to obtain a detailed measurement of the temporal and spatial evolution of this phase change in the next decade. These observations require large (>20m) collecting areas to reach attenuated emission from faint galaxies.
