Presolicitation notice from the National Aeronautics and Space Administration (NASA) Goddard Space Flight Center for a sole source requirement for the Sounding of the Atmosphere using the Broadband Emission Radiometry (SABER) instrument. The SABER instrument is a vital component of the Thermosphere Ionosphere Mesosphere Energetics Dynamics (TIMED) satellite. NASA intends to issue a sole source contract modification to acquire the services from G&A Technical Software, Incorporated (GATS) for the continuation of science data processing, payload operations, and data management for the SABER instrument. The estimated period of performance for this contract extension is 2 years from January 1, 2024, to December 31, 2026. GATS is the only organization currently qualified to perform the subject requirements due to their extensive experience in radiative transfer methods and spaceflight instruments. They have played a significant role in the development and maintenance of the SABER processing system and have the knowledge, skill, and expertise required for the task. Interested organizations may submit their capabilities and qualifications electronically for evaluation.
