About this opportunity

NASA's Johnson Space Center is maintaining a Technical Library for the Commercial Low-Earth Orbit (LEO) Destination Contract (CLDC) that remains accessible for reference purposes, with the most recent update (Draft RFP Data Drop 2) released in late July 2026. The CLDC acquisition itself is on hold; NASA determined in mid-2025 that rather than proceed with a firm-fixed price contract for Commercial LEO Destination certification and services, it will continue supporting U.S. industry's design and demonstration through funded Space Act Agreements (SAA) for the next phase, with future FAR-based acquisition details to be posted on SAM.gov.

The Technical Library contains both controlled (export-restricted) and uncontrolled technical standards, plans, and specifications covering docking systems, payload interfaces, human systems integration, crew health operations, medical standards, hazard analysis and safety processes, communications and RF interfaces, operations standards, and conjunction assessment procedures. Documents are organized into nine standard data drops (released August 2025 through January 2026) and two draft RFP data drops (released July 2026), distributed as .zip files with a master Excel index file. Industry must monitor the CLDC Acquisition Website and SAM.gov for ongoing updates through the Final RFP release.

Access to uncontrolled documents requires a SAM.gov login. Access to export-controlled content requires submission of a completed CLDP Export Control Request Form via email to jsc-cldc@mail.nasa.gov and establishment of SAM.gov access. Foreign nationals from designated countries must obtain an Individual Technology Transfer Control Plan (I-TTCP) and Non-Disclosure Agreement (NDA); those from non-designated countries must comply with International Partner or Foreign National Certification requirements under applicable Programmatic Technology Transfer Control Plans. This activity does not constitute a Request for Proposal, Invitation for Bid, or Request for Quotation and is not a commitment to enter a contract.

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 of new LEO space destinations and supporting systems from private industry. See link here for additional information: https://www.nasa.gov/leo-economy/low-earth-orbit-economy/.  These systems may include end-to-end services such as the in-orbit destination, visiting vehicles, and supporting launch vehicles and ground systems. 

NASA is currently developing Phase 2 requirements for CLD capabilities that would be able to support NASA astronauts, international astronauts, and other spaceflight participants safely in LEO on a commercially owned and operated space station.

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 of new LEO space destinations and supporting systems from private industry. See link here for additional information: https://www.nasa.gov/leo-economy/low-earth-orbit-economy/.  These systems may include end-to-end services such as the in-orbit destination, visiting vehicles, and supporting launch vehicles and ground systems. 

NASA is currently developing Phase 2 requirements for CLD capabilities that would be able to support NASA astronauts, international astronauts, and other spaceflight participants safely in LEO on a commercially owned and operated space station.

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 of new LEO space destinations and supporting systems from private industry. See link here for additional information: https://www.nasa.gov/leo-economy/low-earth-orbit-economy/.  These systems may include end-to-end services such as the in-orbit destination, visiting vehicles, and supporting launch vehicles and ground systems. 

NASA is currently developing Phase 2 requirements for CLD capabilities that would be able to support NASA astronauts, international astronauts, and other spaceflight participants safely in LEO on a commercially owned and operated space station.
