Prime contractors are required to flow down these requirements to their subcontractors to ensure comprehensive data collection and fulfillment of this DRD.

This document provides a preliminary, high-level technical overview of the Landsat 10 (L10) satellite mission, formerly known as Landsat Next. Formulated as a joint partnership between NASA and the U.S. Geological Survey (USGS), the mission aims to continue a 50-year record of moderate-resolution Earth observation data, providing enhanced spatial and spectral resolution for applications like agricultural monitoring and climate resiliency. The L10 observatory features an autonomous onboard scheduling and imaging system utilizing the new World Reference System-3 (WRS-3) grid. The spacecraft manages imaging, deconflicts commands, and transmits compressed data files to the ground via Ka-Band RF links, prioritizing critical files. It also supports off-nadir imaging and carries ten years of consumables for extended operations. The ground segment consists of three main elements: a global Ground Network (GN) for S-band and Ka-band communications, a Mission Operations Center (MOC) designed for extended "lights-out" operations, and a Data Processing and Archive System (DPAS) to ingest, archive, and distribute Level-1 and Level-2 products. Mission integration, testing, and readiness campaigns will utilize an incremental approach, deploying simulators like the Observatory Operational Simulator (OOpS) to validate flight software and procedures. Following a planned 100-day commissioning phase on-orbit, operations will transition to USGS, which will distribute the data freely to the public.

This Quality Assurance Surveillance Plan (QASP) defines NASA Goddard Space Flight Center’s (GSFC) approach to monitoring contractor performance under the Landsat 10 Spacecraft Firm-Fixed-Price contract. The contract covers procurement of a commercial-off-the-shelf spacecraft bus, its integration with the Landsat Instrument Suite (LandIS), and early on-orbit checkout. Operating as a living document, the QASP outlines a hybrid surveillance strategy balancing "insight" (data-driven, low-intensity monitoring) and "oversight" (high-intensity monitoring, including inspections) based on risk. Surveillance is divided into two distinct phases: * **Phase I (Spacecraft Development to Bus Integration):** Employs an insight-based, hand-off approach with minimal government touchpoints for non-critical hardware. However, it applies oversight and limited Government Mandatory Inspection Points (GMIPs) for critical spacecraft interfaces. * **Phase II (Instrument Integration to On-Orbit Acceptance):** Shifts to a strict oversight approach. This phase requires continuous on-site presence of Resident Government Quality Engineers, mandatory GMIPs at all critical interfaces, advance notifications for critical floor activities, and direct participation in failure and material review boards. Ultimately, while the contractor retains primary responsibility for quality control and contract compliance, this QASP establishes the systematic oversight and verification methods NASA will use to ensure overall mission success and safety.

This document, LSDS-2389 Version 2.0, defines the Landsat 10 (L10) Design Reference Case – 18 Days (DRC-18). Under the configuration control of the U.S. Geological Survey (USGS), this reference case outlines the mission's operational image acquisition and instrument calibration scenarios over a single 18-day Worldwide Reference System-3 (WRS-3) ground track repeat cycle. Landsat 10 is a joint initiative of NASA and the USGS under the Sustainable Land Imaging (SLI) Program. Operating a single observatory in a 653 km sun-synchronous orbit, the mission utilizes the Landsat Instrument Suite (LandIS) to provide global, multi-spectral, moderate-resolution land remote-sensing data to ensure data continuity for at least five years. The DRC-18, detailed in an associated spreadsheet, models 14.8 orbits per day and captures three primary science operations: * **Sun-lit Land Imaging (Collection Type-1):** Nominal nadir-viewing Earth imaging over land and coastal targets illuminated at solar angles of 5 degrees or greater. * **Night Imaging (Collection Type-6):** Target-specific acquisitions under darkness to monitor fires, active volcanoes, and urban areas. * **Calibrations and Off-Nadir Observations:** Detailed schedules for routine on-orbit calibrations—including stim lamp (Type-2), solar diffuser (Type-3), and lunar calibrations (Type-5)—as well as selective off-nadir maneuvers (Type-7) for cross-track target acquisitions. The document serves as a baseline for the flight operations, science, and calibration teams to plan and validate mission operations, ensuring Landsat 10 meets its requirements for geometric and radiometric consistency.

This government document contains satellite orbit tracking and data acquisition schedules for Day 1 of a Duty Cycle (DRC) on March 12, 2022. The dataset documents precise collection event times, satellite path coordinates, row designations, and collection type flags for various Worldwide Reference System-3 (WRS-3) paths and rows. The file systematically catalogs sequential orbital passes across three primary paths: Path 122 (from 01:05:04.4 to 02:42:53.1 UTC, covering Rows 1–248), Path 140 (from 02:43:16.7 to 04:20:41.7 UTC, covering Rows 1–248), and Path 158 (from 04:21:05.4 to 05:00:55.5 UTC, covering Rows 1–103). Each tracking entry records: - **DRC Cycle Day:** Fixed at Day 1. - **Scene Center Time:** Exact timestamps in 23-to-24-second intervals. - **WRS-3 Path and Row:** Specific geographical corridor coordinates. - **Collection Type:** A binary flag (0 or 1) indicating active data acquisition vs. standby status. This technical dataset is typically utilized in federal remote sensing, environmental monitoring, or geospatial mapping RFPs to define sensor imaging schedules, plan ground station downlinks, or coordinate calibration activities.

This document outlines the Landsat 10 (formerly Landsat Next) Geometric Error Budget, establishing the end-to-end geometric performance allocations across the spacecraft, instrument (VSWIR and TIR), and ground segments. Prepared by NASA's Goddard Space Flight Center, the document translates 3-sigma engineering allocations into 90% linear error (LE90) or 90% circular error (CE90) ground metrics to verify compliance with Level-3 mission requirements. Key performance areas analyzed include VSWIR and TIR Geodetic Accuracy, Geometric Accuracy (L1TP), Band Registration, Image Registration, and Relative Geodetic Accuracy. The methodology models error propagation by evaluating sensor pointing, spacecraft jitter, ephemeris and timing knowledge, on-orbit alignment stability, and ground calibration capabilities. Notable driving requirements include the tight margins for 10-meter VSWIR band registration and thermal band registration. The budget incorporates updated terms for "relative knowledge" and defines orbit parameters over a 98-minute span. By comparing roll-up predictions against Level-3 requirements, the document demonstrates that the technical requirements are consistent and achievable without incorporating design margins, which are left to individual component vendors.

This NASA and USGS technical presentation outlines the Landsat 10 Geometric Error Budget (GEB) Support, detailing the spacecraft's key geometric performance requirements, error budget components, and end-to-end performance predictions. Formerly known as Landsat Next (LNext), the Landsat 10 project has updated its configuration management and document type conventions to reflect the name change. The document establishes performance models and error trees to predict and verify that Landsat 10 will meet its Level-3 geometric requirements. Key performance metrics include VSWIR geodetic accuracy (predicted at 14.8 meters CE90 against a 30.0-meter requirement), geometric accuracy (predicted at 5.8 meters CE90 against an 8.0-meter requirement), and various band registration limits. Band-to-band registration, particularly for the VSWIR bands, represents the most challenging requirement due to the necessity of transferring geolocation knowledge between bands. To convert observatory-level contributors (such as attitude in microradians and ephemeris in meters) into ground meters, the budget utilizes specific geometric scale factors based on orbital altitude, Earth radius, and ground velocity. Additionally, the budget allocates specific error margins to the spacecraft, instrument payload, and ground segments. This includes provisions for spacecraft jitter, instrument clock and time tag uncertainties, alignment stability, and ground-based calibration algorithms. Ultimately, the predictive models demonstrate that Landsat 10's instrument and spacecraft designs are fully capable of meeting or exceeding all established geometric and image registration requirements.

This document contains vendor questions and official government responses regarding the Draft Request for Proposals (DRFP) for the NASA Landsat 10 spacecraft acquisition (Solicitation 80GSFC26R0015). The exchange clarifies technical, administrative, and contractual requirements to help prospective contractors prepare final proposals. Key areas of discussion include spacecraft design, testing protocols, and compliance standards. The Government clarified that the 50% additional memory requirement (SRD-878) refers to a combined 4Tb of science and ancillary data, which is in addition to the baseline 8Tb. Additionally, NASA confirmed that the Integrated Master Schedule (IMS) is excluded from the 50-page Mission Suitability limit and that Microsoft Project is the desired format. Several questions addressed the balance between traditional NASA Class C mission standards and commercial best practices. While the Government agreed to reevaluate several requirements for the final RFP—such as single-point failures, operating hour accumulations, and FPGA development oversight—it firmly rejected proposals to waive standard compliance clauses, such as patent indemnity, merchantability warranties, and safety reporting. Furthermore, because this is a Firm-Fixed-Price (FFP) contract, NASA stated it will not grant equitable adjustments for supply chain price increases, expecting vendors to manage these pricing risks within their proposals. Lastly, NASA confirmed that artificial intelligence (AI) will not be used to evaluate proposals, and general AI disclosure requirements have been removed from the Statement of Work.
