Expanding Access to Spaceflight
Inclusion is one of the core values NASA has identified as critical for mission success, and the agency is committed to recruiting, hiring, and retaining individuals with disabilities. As part of this commitment, NASA has begun reexamining historical requirements and constraints that have prevented individuals with disabilities from being selected as astronauts. This document provides a preliminary assessment of needed accommodations for specific disabilities on spacecraft design and operations to ensure safety and mission success in spaceflight.
