Abstract:<\/p>\n

I will present first measurements of cosmic expansion and dark energy from the first year of the Dark
\nEnergy Spectroscopic Instrument (DESI). DESI is mapping the sky with a 5000-fiber robotic focal
\nplane and 10 optical spectrographs. I will describe the design of the instrument, the survey, and the
\nanalysis of the first 5 million galaxies and quasars.
\nI will briefly describe the goals for the second-generation survey of DESI, and the successor
\ninstrument Spec-S5. These surveys are designed to improve constraints on dark energy and to probe
\nthe inflationary epoch. Kobayashi-Maskawa Institute
