NASA Electrical, Electronic, Electromechanical, Electro-Optical (EEEE) Parts Selection Process

Lyudmyla Panashchenko Ochs [NASA Goddard Space Flight Center]

Abstract: 

A more general parts selection and verification presentation would be based on the following documents: NASA-STD-8739.10, EEE-INST-002, NASA-STD-8739.11 (not yet released), and S-311-M-70.

Biography: 

Ms. Lyudmyla Panashchenko Ochs has been assisting the NASA Engineering & Safety Center (NESC) in failure analyses, typically of electronic parts like resistors, capacitors, or microcircuits, which is her specialty at the center. Her work is key to ensuring Goddard science instruments can operate reliably for long-duration missions. She helps figure out what led to the failure through extensive ground testing, temperature cycling, vibration, and letting the instrument run for a long time. Her investigations for the NESC have included the Hubble Space Telescope and ISS. Most recently, she and her team analyzed a capacitor used on both the ISS Universal Waste Management System and throughout the Artemis campaign, demonstrating the cause of on-orbit failure.
