Abstract
Progress in STAR over the last two years and projections for the coming two years are discussed. Important technical developments have been the completion of the barrel and endcap electromagnetic calorimeters. Measurement of inclusive pi_0 and jet A_LL over the next two years are expected to answer whether G is a major contributor to the proton's spin. Transverse effects such as Collins and Sivers functions at mid-rapidity will also be investigated.
