NASA has determined that, rather than moving forward at this time with a firm-fixed price contract for Commercial LEO Destination (CLD) certification and services, NASA will continue to support U.S. industry�s design and demonstration of CLDs with funded Space Act Agreements (SAA) for the next phase. Details regarding this or any future acquisition related to CLD certification and services will be posted on www.sam.gov. This CLDC Technical Documents Library will remain accessible for reference purposes to provide technical documents to the CLDC Technical Library site to keep industry up to date on current NASA technical standards that may be relevant for a future FAR-based acquisition. This Library is not to be associated with or required for compliance with any other acquisition or SAA effort. Technical Documents associated with this Library will be updated in "Data Drops" moving forward. Technical Documents are contained within .zip files with an index for all uploads being contained within the Excel file "CLDC Tech Library Contents.xlsx". This activity does not constitute a Request for Proposal, Invitation for Bid, or Request for Quotation and it is not to be construed as a commitment by the Government to enter a contract. Please continue to monitor www.sam.gov postings and the Acquisition Website for updates on the release of any CLDC information. ***************** (End of Modification 1) ***************** This National Aeronautics and Space Administration (NASA/Lyndon B. Johnson Space Center (JSC)) is establishing the Technical Library for all potential offerors to the Commercial Low-Earth Orbit (LEO) Destination Contract (CLDC). It is expected that the Technical Library will be updated periodically through the acquisition period. It is the potential offeror's responsibility to monitor the website for updates to the technical library. Additional technical and strategic information along with a preliminary schedule can be found in the CLDC Acquisition Website: https://www.nasa.gov/johnson/jsc-procurement/cldc/. Please note, the documents/links on the CLDC Acquisition Website listed above are for information and planning purposes to allow industry the opportunity to comment and to promote competition. Access to Export Controlled content in the Technical Library To request access to Export Controlled content (marked as EXP-CTRL), you must provide a completed �CLDP Export Control Request Form� via email to jsc-cldc@mail.nasa.gov. When responding, reference CLDP Export Control Request Form in the subject line. Please note that after the request form is submitted, you must have a log in for www.sam.gov. Once logged in, click the request access button in the Attachments/Links section of the announcement. The www.sam.gov system help webpage is available here: https://www.sam.gov/help#goToExplore. All foreign nationals from designated countries covered by a Programmatic Technology Transfer Control Plan (PTTCP) or requiring access to export controlled information are required to have an Individual Technology Transfer Control Plan (I-TTCP) with a Non-Disclosure Agreement (NDA). Foreign nationals from non-designated countries requiring access to export-controlled information covered by a P-TTCP are required to comply with the International Partner or Foreign National Certification contained in the P-TTCP. CLDC Phase 2 Background As NASA plans for the retirement of the International Space Station (ISS) at the end of the decade, the ability of private industry to take on the task of providing routine utilization of LEO and maintaining a continuous U.S. presence in space is of vital importance to both NASA and U.S. goals. In a multiphase strategy, JSC�s Commercial LEO Development Program (CLDP) is helping spur the development

Value counts single-winner awards. "Shared" awards are multiple-award contracts that list every winner with the same total ceiling; that ceiling is not one company's win, so it is not added in. Revenue next to a ticker is the company's last annual revenue from its 10-K.
- $AMTM reported $7.9B revenue in FY2025. The median single-winner award in these 157 past awards, $14.0M, is 0.2% of that. 10-K
One award's total value against one year of revenue; many awards are paid over several years.

Materiality: one award's value as a share of the winner's revenue over the latest 12 months in its SEC filings (or its last fiscal year, as noted when you point at it). Low under 1%, Medium 1 to 5%, High 5% or more. Many awards are paid over several years, so this overstates a single year's share.
