The Relativistic Heavy Ion Collider (RHIC), the first hadron accelerator and collider consisting of two independent rings, has completed its fourth year of operation since commissioning in 1999. RHIC is designed to provide luminosity over a wide range of beam energies and species, including heavy ions, polarized protons, and asymmetric beam collisions. RHIC has produced physics data at four experiments in runs that include gold-on-gold collisions at various beam energies (9.8, 31, 65, and 100 GeV/u), high-energy polarized proton-proton collisions (100 GeV), and deuteron-gold collisions (100 GeV/u). We review recent machine performance for high-luminosity gold-gold operations and polarized proton operations, including causes and solutions for known operational limits. Plans and progress for luminosity and polarization improvements, electron cooling, and the electron-ion collider eRHIC are discussed.
