Recent precise polarization measurements have considerably improved constraints on nucleon electromagnetic form factors. The BLAST experiment, carried out at MIT-Bates Linear Accelerator Center, was designed to study these quantities systematically using the intense polarized stored electron beam of the South Hall Ring, highly polarized internal gas jet targets, and a symmetric toroidal spectrometer. Simultaneous measurements of multiple reaction channels with different combinations of beam and target polarizations were carried out to extract the nucleon form factors with high precision at Q2< 1 GeV2/c2. Results for the nucleon form factors G{sub E}{sup p}, G{sub M}{sup p}, G{sub E}{sup n}, and G{sub M}{sup n} are presented and discussed.
