title = "Nautilus Space Observatory: a very large aperture space telescope constellation enabled by scalable optical manufacturing technologies",
abstract = "We describe progress on the Nautilus Space Observatory concept that is enabled by novel, very large (8.5m-diameter), ultralight-weight, multi-order diffractive lenses that can be cost-effectively replicated. The scientific goal of Nautilus is the rigorous statistical exploration of one thousand potentially life-bearing planets and the assessment of the diversity of exo-earths. Here we review the science requirements and key design features of Nautilus. The new optical technology (MODE lenses) at the heart of the Nautilus telescopes also poses exciting new optical fabrication and metrology challenges. We will summarize these challenges and provide an overview of emerging solutions.",
