About this file
This document is a Draft Contract Data Requirements List (CDRL) and Data Item Descriptions (DID) for the Landsat Next Spacecraft project at NASA's Goddard Space Flight Center. The comprehensive document outlines detailed requirements for multiple data deliverables across ten categories: Program Management, Reviews, Flight Software, Integration and Test, Systems Engineering, Launch Vehicle, Simulators, Spacecraft, Systems Assurance, and Operations. Each category contains multiple Contract Data Requirements List (CDRL) items with specific delivery dates, maturity levels, and preparation instructions.
The CDRL covers a wide range of technical documentation requirements, including thermal models, mass properties reports, software development plans, test procedures, safety compliance checklists, materials identification lists, and operational documentation. Deliverables are structured with precise submission timelines relative to key project milestones such as Spacecraft Systems Requirements Review (SC SRR), Preliminary Design Review (PDR), Critical Design Review (CDR), and various mission phases. The document is marked as Draft 5 and dated December 3, 2025, indicating it is a working document for the Landsat Next spacecraft development project at NASA's Goddard Space Flight Center in Maryland.

1.0 INTRODUCTION
This Contract Data Requirements List (CDRL) document defines the requirements for deliverable documentation to be provided by the Spacecraft (SC) Contractor. Section 2.0 includes definitions and instructions for mailing and/or distribution. The table in Sections 3.1.1 through 3.1.8 present the CDRL item by item, with due dates, and media format. Section 4.0 provides the Description of Required Data (DRD) or Data Item Descriptions (DIDs), a description of each item, which describes the use for the deliverable and the required preparation information; except where specifically indicated to the contrary, the formats and drawing standards used shall be those normally used by the SC Contractor and by its Subcontractors.
2.0 DEFINITION OF DUE DATES/MATRUITY, DEFINITION OF
CATEGORIES, AND MAILING DISTRIBUTION INSTRUCTIONS
2.1 DUE DATES - RELATED DEFINITIONS
The following definitions apply to the DUE DATE column in the tables in Section 3.1.1 through
3.1.8. Unless otherwise specified, deadlines are in calendar days. Submissions can be made before the due date if the Contractor believes that no changes will be made between the submittal date and the due date.
2.1.1 Due Date
DUE DATE: The contract baseline schedule for delivery of SOW CDRL items is shown in the CDRL tables in Sections 3.1.1 through 3.1.8; items in the schedule for delivery are associated with acronyms for the various program reviews that form the contract baseline. Items designated for delivery "As Generated", or "Update As Required (UAR)" shall be provided to the Government within the timeframe specified in the table or as agreed to by the Government.
Monthly: Submitted on monthly basis L: Launch Date DACA: (Calendar) Days After Contract Award NLT: No later than Other entries in the "DUE DATE" column are self-explanatory.
2.2 MATURITY
The following definitions apply to the MATURITY column in the tables in Sections 3.1.1 through 3.1.8.
(1) Initial: The first submission of an item, which will be revised and resubmitted at a later date.
(2) Preliminary: An early submission of an item. To be completed as is practicable at the time of preparation. Preliminary submittals are written with the best available current information and are resubmitted when further information becomes available.
(3) Final: The complete, thorough submission of an item for approval, review, or information that, to the best of the Contractor’s knowledge and intention, will not require further revision or updates. However, this type of submission does not preclude updating if later found to be necessary. Any updates shall require the same "approval/review" process as was required for the original final submissions.
(4) Baseline, Current: The delivery is written with the best up-to-date information available at the time.
(5) Update: The delivery is revised with the best up-to-date information available at the time.
Other entries in the "MATURITY" column are self-explanatory.
2.3 CATEGORY
The following definitions apply to the CATEGORY column in the tables in Sections 3.1.1 through 3.1.8. If separate approval instructions are not specified for separate submission due date/maturity items, then the listed approval instruction applies to all submissions.
A Approval. CDRL items in this category require approval by the GSFC Contracting Officer’s
Representative (COR) or Contracting Officer (CO) prior to use by the Contractor. Receipt by the Government shall occur within the time specified in the "Due Date" column in the tables in Sections 3.1.1 through 3.1.8 of this document.
Requirements for re-submission shall be as specified by the Contracting Officer or Contracting Officer's Representative. In most cases, the Contractor will be required to resubmit the document within 14 calendar days of receiving comments from the Government. If the Contractor has not received a response from GSFC within 45 calendar days of delivery of a CDRL item, the Contractor may proceed as if the document has been approved.
R Review. Documents in this category require delivery to the Government prior to use and within the time period specified in the "Due Date" column in the tables in Sections 3.1.1 through 3.1.8 of this document. They are subject to evaluation by the Government or its designated representatives to determine Contractor effectiveness in meeting Contract objectives. Upon submission, the Contractor may proceed with associated work while the Government reviews the submission.
I Information. Data in this category shall be delivered to the Government within the time period specified in the “Due Date” column in the tables in Sections 3.1.1 through 3.1.8 for the purpose of determining current program status, progress, and future planning requirements. The Government may request changes on deliverables where errors or omissions are noted.
2.4 MEDIA
All data items shall be delivered in electronic format to a mutually defined web portal that allows external Government and Contractor access unless otherwise noted in the tables in Sections 3.1.1 through 3.1.10.
The CO shall be notified of electronic submission of the deliverable via email.
Electronic deliverables shall be delivered in the following formats unless otherwise approved by the Government:
