Exhibit 5 - L10 Spacecraft Specifications Fill-in.xlsx

This is a spacecraft technical specification fill-in template for the Landsat 10 spacecraft acquisition. The document provides a comprehensive framework for vendors to specify their proposed spacecraft bus capabilities across multiple subsystems, with an example entry demonstrating how to complete the form using the "NCC-1701 Constitution Class" bus product line.

The template requires detailed specifications across eight major subsystem categories: spacecraft bus top-level information (design life, mass, propellant capacity); power systems (generation, storage, bus voltage, solar array configuration, battery specifications); propulsion (delta-V capability, thruster specifications, propellant type); thermal management (heater circuits, heat pipes, power consumption); mechanical structure and mechanisms (release actuators, modal frequency, interface dimensions); attitude control systems (control modes, sensor types, actuators, reaction wheels, processing rates); communications (command/telemetry links, encryption, transceiver models, antenna specifications, data rates up to 3 Mbps for telemetry and science link capabilities); and command and data handling (processor specifications, memory capacity, flight software parameters, instrument interfaces supporting multiple data standards). Vendors must populate specifications for their proposed solution alongside corresponding product line baseline specifications, noting any areas requiring customization. The example indicates typical trade-offs, such as customizing battery chemistry from standard NiCAD to LiPo or modifying bus voltage from standard 70VDC to 28VDC, helping proposers understand the level of detail and comparison required for this NASA Goddard Space Flight Center solicitation (80GSFC26R0015).
