Human Spaceflight and Aviation Standards
The Human Spaceflight and Aviation Standards Team continuously works with subject matter experts and with each space flight program to provide the best technical requirements and implementation documentation to support the development of new programs.
NASA-STD-3001
NASA-STD-3001, NASA Spaceflight Human-System Standard Volume 1 and 2, establishes Agency standards 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 Standards are determined based on each program’s mission profile and procurement strategy.

OCHMO Independent Assessments
Independent assessment plays a crucial role in NASA’s long-term success by addressing essential questions requiring rapid response to support further program development. The Office of the Chief Health and Medical Officer (OCHMO) uses this process as a tool for decision-making and providing unbiased insight into issues that arise concerning crew health and safety. Technical Interchange Meetings (TIMs) allow NASA subject matter experts (SMEs) to consult with outside experts from industry, academia, hospitals and clinical settings, and the military to better understand specific risks, gain knowledge of current best practices and cutting-edge research occurring outside NASA, and to answer questions on topics the NASA SMEs develop and share prior to the meeting. Results of these independent assessment TIMs are incorporated into the NASA-STD-3001 documents, future editions of OCHMO technical briefs, informative summary reports, and/or program technical memos.

Assessment of Oxygen Toxicity and Neurovestibular Disturbances during Neutral Buoyancy Laboratory (NBL) Exploration Spacesuit Testing and Review of Requirements
Applicable to Personnel Participating in Diving, Hyper/Hypobaric Chambers, and Pressurized Suit Operations (JPR 1830.6)
NASA’s Office of the Chief Health and Medical Officer (OCHMO) initiated a working group to investigate operations in the Neutral Buoyancy Laboratory (NBL) and determine the possible causes of adverse physiological effects that have been experienced by subjects operating exploration spacesuits during 1/6G simulations in the NBL training platform.
Note: The content discussed in this report, including the test parameters, symptomology, and recommendations are applicable only to the NBL and are not transferrable to spaceflight operations.
