Applying Human Rating to the
NASA-STD-3001: An Overview

NASA-STD-3001, NASA Spaceflight Human-System Standard Volume 1 and 2, establishes Agency-level technical requirements that enable human spaceflight missions by minimizing health risks, providing vehicle design parameters, and optimizing performance of flight and ground crew. Applicability and tailoring of these requirements are determined based on each program’s mission profile and procurement strategy.

While NASA-STD-3001 provides the most comprehensive resource for these agency level requirements, a core subset is applicable to human rating. Requirements categorized as “Human Rated” follow three key human-rated space system principles:

1. System level safety features;
2. Accommodation of human interaction with system; and
3. Safe recovery.

NASA-STD-3001 Pyramid Hierarchy

A “Standards pyramid of hierarchy” was developed to aid in the determination of individual standard’s impact on missions—particularly useful during the formulation stage of new programs. This tool provides a look “across” all current NASA-STD-3001 requirements in a condensed, hierarchical format useful for assessing impact on a mission’s success related to loss of crew, mission, and/or individual mission objectives. The pyramid also categorizes the technical requirements that increase the probability of achieving mission objectives.

To provide clarify on requirements categorized as ‘Human Rated,’ the Standards Pyramid was categorized into two groups: human-rated and those classified as primarily enabling and optimizing performance. While all NASA-STD-3001 requirements are considered valuable to human spaceflight, a subset of Human-Rating requirements was developed to serve as a guidepost for need-to-have factors critical for maintaining human safety (e.g. foundational vehicle structure; environmental conditions; safe egress).

What is a Human-Rated Space System?

A human-rated system accommodates human needs, effectively utilizes human capabilities, controls hazards with sufficient certainty to be considered safe for human operations, and provides the capability to safely recover from emergency situations. The concept of human-rating a space system entails three fundamental tenets:

1. Human-rating is the process of evaluating and assuring that the total system can safely conduct the required human missions.

2. Human-rating includes the incorporation of design features and capabilities that accommodate human interaction with the system to enhance overall safety and mission success.

3. Human-rating includes the incorporation of design features and capabilities to enable safe recovery of the crew from hazardous situations.

Full compliance for human rating occurs when all levied requirements or considerations at each level have been appropriately addressed.

Hierarchy Descriptions

• 0 Fundamental System Needs – Meeting the requirements needed to enable a vehicle or suit that provides the minimum structural needs for a crewmember to be contained within or to have an emergency egress.
• 1 Basic Human Needs and Life Support – The minimum requirements for a human to survive.
• 2 Safety, Security & Vehicle Operations – Vehicle design and operations that ensures the safety of the crew (pre-, in- and post-mission).
• 3 Human & Vehicle Maintenance – Vehicle and crew maintainability needs, either through equipment design or capabilities that enable continued support of the crew and vehicle health.
• 4 Enabling and Optimizing Human and Mission Performance – Additional requirements that would optimize the mission by enabling the success of mission objectives and the crew health or performance.

“The concept of a man-rated space system entails the incorporation of those design features and requirements necessary to accommodate human participants within the system and thus provide the capability to safely conduct manned operations, including safe recovery from any credible emergency situation. Man-rating is the process of evaluating and assuring that the total system, both hardware and software, has the ability to meet prescribed, safety oriented design and operational criteria and requirements, and becomes involved in all program activities including design and development, test and verification, management and control and finally, certification for operational readiness”

“A Review of Man-Rating in Past and Current Manned Space Flight Programs”, A. Bond, 1988
