Exhibit 3 - L10 Spacecraft Master Equipment List (MEL) Fill In.xlsx

This file is a Master Equipment List (MEL) template for the Landsat 10 Spacecraft procurement, designed for offerers to complete and submit as part of their proposal response. The spreadsheet template provides a structured format for contractors to document all spacecraft components and subsystems, requiring entries across multiple technical and programmatic columns including part information, unit quantities, mass data, subsystem classification, component details, vendor information, part numbers, program heritage, flight unit quantities, Engineering Development Unit (EDU) quantities, basic mass in kilograms with Certification-Based Evidence (CBE), Margin Growth Allowance (MGA) percentages per AIAA S-120A-2015 standards, predicted mass calculations, and power consumption in watts.

Offerers responding to NASA Goddard Space Flight Center's Solicitation 80GSFC26R0015 for the Landsat 10 Spacecraft acquisition must complete this MEL as part of their proposal submission, providing comprehensive equipment-level technical data that demonstrates their proposed spacecraft design and component selections. This template serves as a critical tool for evaluating contractor proposals by ensuring standardized presentation of spacecraft configuration, mass budgets, and power requirements across all competing offers, allowing NASA to conduct consistent technical comparisons among proposals.
