About this file
This document contains a request for information and questions and answers related to a Low Earth Orbit Earth Observation System Sounder for Microwave-Based Applications. The National Aeronautics and Space Administration Goddard Space Flight Center is seeking input on the feasibility of conducting a definition-phase study with a fixed price of approximately $5 million and duration of 12 months. The study scope and requirements are outlined in draft documents including a Statement of Work, Performance Specification Document, and Instrument Mission Assurance Requirements. Interested firms are requested to provide feedback on the clarity and reasonableness of the requirements as well as any areas that would benefit from early technology development or risk mitigation. Capability statements of no more than 5 pages are also requested from those able to meet the outlined requirements. Responses are due by November 8, 2022 and should be submitted electronically to the specified point of contact.

Low Earth Orbit (LEO) Earth Observation System (LEOS) Sounder for Microwave-Based Applications
(SMBA)
Questions and Answers
January 24, 2023
4. If there is a Commercial-Off-the-Shelf (COTS) component where one of the piece parts changed how is NASA notified about this? For example, a piece part within a COTS component had its foundry location changed.
During the Phase 1 process, not necessarily prior to the Phase 1a report, the Standard Components Commodity Risk Assessment Engineer (SC CRAE) will request the following information for each designated item from the Safety and Mission Assurance (SMA) lead (or designee) of the procuring organization:
1. Parts that have been changed from prior designs
2. On-orbit catastrophic failure times of the item itself and cause, if known
3. Major environmental differential from past experience relative to current application
4. Longest achieved lifetime of the item in similar orbit
5. Change in printed circuit board specification used as standard practice
6. Changes in the printed circuit board design
7. Change to high density interconnect design or high-density interconnect features
8. New major special restrictions on board materials (e.g., switch to halogen free laminate)
9. Major changes in soldering approach (e.g., switch to lead-free solder)
10. Major materials approach changes
11. Switch to additive manufactured items
Given that part of the initial process is asking the question about what has changed about a particular part within a component, NASA will obtain knowledge of these types of changes. NASA will ask follow-on questions to provide themselves with the needed information to assure the design at the component level can withstand any particular change at the piece part level. If some information is unavailable, this will not necessarily disqualify the pertinent item(s), as other information may be sufficient to address the concern.
To a great extent, NASA’s interest is more in the line of what is being done in the design to mitigate the effects of radiation, than it is about the radiation hardness of individual parts in the circuit so that it is less susceptible to unexpected events on orbit or unexpected parts manufacturing or design changes on the ground.
