The Gemini Planet Imager: Looking back over five years and forward to the future

The Gemini Planet Imager(GPI), a coronagraphic adaptive opticsinstrument designed for spectroscopy of extrasolar planets, had first lightin 2013[13]. After five years, GPI has observed more than 500 stars, producing an extensive library of science images and associated telemetrythat can be analyzed to determine performance predictors. We will present a summary of on-sky performance and lessons learned. The two most significant factors determining bright star contrast performance are atmospheric coherence timeand the presence of dome seeing. With a possible move to Gemini North, we are planning potential upgrades including a pyramid-sensor based AO system with predictive control; we will summarize upgrade options and the science they would enable.
