I will outline the details of a large (250-orbit) HST spectroscopic survey of Lyman-Alpha emitters (LAEs) at z > 5.5 and star-forming galaxies (H-alpha, H-beta, [OIII], [OII]) at 0.5 < z < 2.0. The WFC3/IR grism will be used in parallel to COS primary observations of QSOs, with typical visit durations of 4-5 orbits. We expect to detect 40-100 LAEs at z > 5.5 and 1000 H-alpha emitters at 0.5 < z < 1.5. With these data we will determine the evolution in the LAE luminosity function at the epoch of reionization, and better characterize the properties (star formation rates, metallicities, dust extinction) of galaxies at the epoch of peak star formation rate density. Preliminary results from the first observations (scheduled for Nov. 2009) will be presented.
