This federal contract award, valued at $296,728.31, was granted by the National Aeronautics and Space Administration (NASA) to The Aerospace Corporation, a federally funded research and development center (FFRDC). The contract is for research to make transformative observations of main belt asteroids using ground-based optical polarimetry. The goal is to verify linear polarization variations and circular polarization results on asteroids (1) Ceres, (4) Vesta, and (7) Iris, as well as observe six additional bright main belt asteroids for longitudinal albedo variations and circular polarization signatures. The contract also aims to observe three high radar albedo asteroids to search for circular polarization from metalliferous surfaces. This award is not designated as a set-aside contract. The Aerospace Corporation holds several key indefinite delivery contracts with NASA and NOAA that enable the company to provide specialized engineering, evaluation, and advisory services for civil and defense space programs.
