The MaNGA Survey (Mapping Nearby Galaxies at Apache Point Observatory) is oneof three core programs in the Sloan Digital Sky Survey IV. It is obtainingintegral field spectroscopy (IFS) for 10K nearby galaxies at a spectralresolution of R~2000 from 3,622-10,354A. The design of the survey is driven bya set of science requirements on the precision of estimates of the followingproperties: star formation rate surface density, gas metallicity, stellarpopulation age, metallicity, and abundance ratio, and their gradients; stellarand gas kinematics; and enclosed gravitational mass as a function of radius. Wedescribe how these science requirements set the depth of the observations anddictate sample selection. The majority of targeted galaxies are selected toensure uniform spatial coverage in units of effective radius (Re) whilemaximizing spatial resolution. About 2/3 of the sample is covered out to 1.5Re(Primary sample), and 1/3 of the sample is covered to 2.5Re (Secondary sample).We describe the survey execution with details that would be useful in thedesign of similar future surveys. We also present statistics on the achieveddata quality, specifically, the point spread function, sampling uniformity,spectral resolution, sky subtraction, and flux calibration. For our Primarysample, the median r-band signal-to-noise ratio is ~73 per 1.4A pixel forspectra stacked between 1-1.5 Re. Measurements of various galaxy propertiesfrom the first year data show that we are meeting or exceeding the definedrequirements for the majority of our science goals.
