Elaine Stewart

Elaine Stewart serves as a key procurement professional at NASA’s Goddard Space Flight Center, where she manages complex acquisitions for advanced space-based instrumentation and mission-critical systems. Her role centers on executing full lifecycle contracting for high-precision scientific sensors, navigation systems, and deep-space communication technologies that support Earth observation and astrophysics missions. She ensures alignment with NASA’s strategic objectives in space science and Earth system monitoring, applying rigorous technical evaluation and acquisition planning to procure cutting-edge aerospace systems. Her portfolio primarily involves sole-source and competitive procurements for mission-essential hardware and integrated payloads requiring stringent performance and reliability standards. Stewart maintains enduring relationships with leading technical partners including Aerospace & Commercial Technologies, LLC, and the Massachusetts Institute of Technology’s Lincoln Laboratory. These collaborations are characterized by deep technical engagement, long-term contract performance, and co-development of specialized spaceflight hardware. Her contracting approach emphasizes partnership with organizations possessing proven expertise in aerospace systems integration, sensor design, and radiation-hardened electronics, often engaging vendors through cost-reimbursement and firm-fixed-price contracts tailored to R&D-intensive environments. Stewart’s procurement portfolio reflects a strict focus on open competition, with 100% of awards issued under no set-aside classifications. She does not routinely utilize socioeconomic programs such as 8(a), HUBZone, or SDVOSB set-asides, instead prioritizing technical capability and mission readiness over socioeconomic criteria. This reflects the highly specialized nature of Goddard’s procurements, where only a limited number of vendors possess the required heritage, security clearances, and engineering expertise. Her primary procurement focus lies in NAICS 334511, encompassing the manufacturing of aerospace navigation, guidance, and detection systems. She consistently acquires advanced instrumentation for satellite payloads, including spectrometers, star trackers, attitude control sensors, and deep-space transceivers. Her domain expertise spans spaceborne remote sensing, autonomous spacecraft systems, and radiation-tolerant electronics, ensuring that all acquisitions meet the extreme environmental and operational demands of orbital and interplanetary missions.
