Melissa Vess

Melissa Vess serves as a WFIRST Spacecraft Systems Engineer, providing technical leadership and systems engineering oversight for the development and integration of spacecraft subsystems critical to NASA’s Wide Field Infrared Survey Telescope mission. In this role, she acts as a key technical liaison between engineering teams and acquisition professionals, ensuring that procurement decisions align with mission-critical performance requirements, spacecraft architecture, and systems engineering best practices. Her acquisitions typically focus on high-reliability space-qualified hardware, avionics, thermal control systems, and payload integration components, requiring rigorous compliance with NASA engineering standards and spaceflight heritage criteria. While no specific contractor relationships are currently identifiable in the procurement record, Melissa collaborates with a network of aerospace prime contractors and specialized subsystem vendors capable of delivering space-rated components under strict environmental and qualification protocols. Her working relationships emphasize technical readiness, proven flight heritage, and rigorous test validation, favoring vendors with demonstrated experience in spacecraft systems integration and NASA’s procurement compliance frameworks. Melissa’s procurement pattern reflects a strong preference for open competition, with 100% of acquisitions classified as “No Set-Aside.” This indicates a focus on technical merit and mission necessity over socioeconomic preferences, consistent with the highly specialized and mission-critical nature of spaceflight hardware procurement where qualification and performance take precedence over socioeconomic categories. Her primary procurement focus is centered on NAICS 336419—Other Guided Missile and Space Vehicle Parts and Auxiliary Equipment Manufacturing—reflecting deep expertise in spacecraft subsystems including power distribution, command and data handling, attitude control, and structural interfaces. She routinely sources high-integrity components requiring radiation tolerance, extreme thermal stability, and long-duration reliability in low-Earth or heliocentric orbits, demonstrating specialized knowledge in space systems engineering and mission assurance practices.
