The Absolute Color Calibration Experiment for Standard Stars (ACCESS) 1, is the first of four flights of a new payload to obtain absolute spectrophotometric calibration of the National Institute of Standards and Technology (NIST) laboratory irradiance standards to a precision of 1% in the 0.35 – 1.7µm bandpass at a spectral resolution greater than 500 by directly tracing the observed stellar fluxes to NIST laboratory irradiance standards. Transfer of the NIST detector standards to the target stars will produce an absolute calibration of these standards in physical units, including the historic absolute standard Vega. This improved network of standard stars, extending to 10th magnitude, will be available to all telescopes as standard sources.
