Crew Transportation Technical Standardsand Design Evaluation CriteriaCCT-STD-1140Revision: B-11.0 IntroductionUnder the guidance of processes provided by Crew Transportation Plan (CCT-PLN-1100), thisdocument with its sister documents, Crew Transportation Technical Management Processes (CCTPLN-1120), International Space Station (ISS) Crew Transportation and Services RequirementsDocument (CCT-REQ-1130), Crew Transportation Operations Standards (CCT-STD-1150), and ISS toCommercial Orbital Transportation Services Interface Requirements Document (SSP 50808), providethe basis for a National Aeronautics and Space Administration (NASA) certification for services to theISS for the Commercial Provider. When NASA Crew Transportation System (CTS) certification isachieved for ISS transportation, the Commercial Provider will be eligible to provide services to andfrom the ISS during the services phase of the NASA Commercial Crew Program (CCP).1.1 PurposeIn the course of over fifty years of human space flight, NASA has developed a working knowledge andbody of standards that seek to guide both the design and the evaluation of safe designs for spacesystems. The purpose of this document is to inform potential Commercial Providers of thespecifications, standards, and products/artifacts that NASA considers crucial to a successfuldevelopment effort and to provide the Commercial Provider with NASA expectations, essentially thetechnical criteria, used in assessing these items to ensure they meet the intent of Sections 3.9 through3.12 of CCT-REQ-1130.The evaluation of technical standard requirements that utilize the "meet the intent of" language areaddressed in this volume and may be satisfied through the use of alternative standards instead of theNASA, military, or industry standard listed. For these alternative standards, this document will beutilized to define the evaluation criteria that the CCP will use to determine whether the proposedstandard is acceptable.Discipline specific technical work products/artifacts (e.g., plans, analyses, reports, etc.) are also calledout in this volume, along with the criteria that will be used to evaluate them. The intent is to identifyproducts that NASA deems critical to the ultimate successful certification of a CTS. It is NASA’sexpectation that any Commercial Provider’s successful development activities would already involvethese products. It is not NASA’s intent to convey a request for formal deliverables by listing these itemsin the technical products section of this document.This document is organized by discipline, with each section containing the key products and technicalassessments that will be used as a benchmark to determine acceptability of the Commercial Provider’stechnical standards and products.Once the Commercial Provider and NASA have reached an agreement on an alternative technicalstandard, it will be added to the partnered set of standards for the CTS. Once this partnered set ofstandards is in place, it will be used in design evaluations in lieu of the standard called by CCT-REQ1130. The content of this document will continue to be utilized as a reference for the types of productsand analysis that are typically evaluated to establish technical adequacy for each discipline.Commercial Crew ProgramPage 4 of 86

Crew Transportation Technical Standardsand Design Evaluation CriteriaCCT-STD-1140Revision: B-11.2 ScopeThis document includes the criteria, expectations, and insight criteria that will be used in the evaluationof technical standards for launch vehicle, spacecraft, and ground system requirements identified by theCCP and the ISS Program for the CTS. The CTS refers to all assets and services necessary to meet therequirements of CCT-REQ-1130, including pre-flight planning, trajectory and abort analysis, groundprocessing and manufacturing, ground operations, mission control, training, launch control, launch, onorbit operations, post-landing recovery operations, safety and mission assurance, and all other functionsrequired for safe and successful human space flight missions. When elements of the CTS are technicalor specific to a requirement, they will be called out; for example, the term CTS spacecraft will be usedwhen the launch vehicle and ground elements are not specific to that portion of the design.1.3 PrecedenceIn the event of a conflict between the text of this document and references cited herein (listed in Section2.0), the text of this document takes precedence. The exception to this statement is for SSP 50808,which takes precedence during the arrival, docked, and departure operations. Nothing in this documentsupersedes applicable laws and regulations, unless a specific exemption has been obtained.1.4 Delegation of AuthorityThis document was prepared by NASA’s CCP, and will be maintained in accordance with standards forCCP documentation. The CCP is responsible for assuring the definition, control, implementation, andverification of the requirements identified in this document.Commercial Crew ProgramPage 5 of 86
