NASA-STD-3001 Volume 2, Revision E, NASA Spaceflight Human-System StandardVolume 2: Human Factors, Habitability, and Environmental Health

NASA-STD-3001 Volume 2 establishes technical requirements for human-related vehicle system design and operations that maintain astronaut safety and promote performance. NASA-STD-3001, NASA Spaceflight Human-System Standard Volumes 1 and 2, establishes Agency technical requirements that enable human spaceflight missions by minimizing health risks, providing vehicle design parameters, and enabling the performance of flight and ground crew. Applicability and tailoring of these technical requirements are determined based on each program’s mission profile and procurement strategy.
The majority of NASA-STD-3001 Vols. 1 & 2 are performance technical requirements, meaning they state technical requirements in terms of desired results without stating a method for achieving it. All technical requirements contain a “shall” statement and can be followed by a short, italicized rationale statement. Rationales are intended to provide additional information for the implementation of the technical requirements. NASA-STD-3001 Standards are overarching and apply to all of NASA’s Spaceflight Programs. These technical requirements are essential pieces used to create program requirements that lead to successful designs and implementations.
