Closure Rationale

While DCS research and operational development is of high importance, this work is now funded by organizations other than HRP, in a collaborative joint effort. Details of DCS-related work that is already being done (or planned to be done) may be found in the comprehensive NASA technical paper “Integrated Extravehicular Activity Human Research and Testing Plan” (NASA/TP-2019-220232). As part of HRP’s new strategy, it will contribute to these operational efforts as needed.

Description
Gap 1 will help define the standard by which DCS needs to be prevented.


Initial state
:
Acceptable risk for ISS was defined as part of the prebreathe reduction program. This acceptable risk was not made into an agency standard, but did go into determining the accept/reject standards for the prebreathe reduction program, which established the current procedures

 

Approach:

A multidisciplinary working group including NASA scientists, engineers, mission operations personnel and flight surgeons as well as industry, military and academic experts will convene to determine the level of acceptable DCS risk based on the desired work efficiency index (WEI), DRM objectives and DCS treatment capabilities for a given Exploration Environment.

 

Target for Closure
