NASA's National Aeronautics and Space Administration (NASA) is seeking high voltage electrical engineering consulting services for the MoSAIC instrument project under the Geospace Dynamics Constellation mission. The primary objective is to engage senior-level electrical engineers to evaluate the design and implementation plan of high voltage boards within the electrical subsystem, focusing on circuit architecture, performance metrics, and recommendations for design considerations. This consulting effort is critical for enhancing technical design and implementation strategies essential to the mission's success, with the project scheduled to run from October 1, 2024, to September 30, 2025. Interested organizations must submit their capabilities and qualifications in writing to McKenzie Hanson at mckenzie.m.hanson@nasa.gov by 3:00 p.m. Central Standard Time on October 18, 2024.
