Species Studied
Scientific Name: Homo sapiens Species: Human

Description
OBJECTIVES:
Currently, the Test Device for Human Occupant Restraint (THOR) is a biofidelic Anthropomorphic Test Device (ATD or crash test dummy). This ATD is the best solution for future occupant protection standards and requirements; however, the THOR responses are not well correlated to low injury risk. Since automotive research is directed at preventing severe injuries in very low probability events, and because NASA vehicles will land every time, a lower risk of injury is needed. NASA requires this lower level of injury risk; therefore, new injury risk functions for the THOR are needed.

The specific aims for this study are as follows:

  1. Identify appropriate datasets for THOR comparison
  2. Test THOR in same conditions as historical testing
  3. Use historical human data to establish tolerance and injury risk focusing on lateral responses and sex differences
  4. Use Bayesian analysis combined with survival analysis along with human tolerance to estimate injury risk.
  5. Use results of prior data mining and existing literature as prior distribution
  6. Develop new Injury Assessment Reference Values based on the new statistical analysis

Human Research Program (HRP) Human Research Roadmap (HRR) Information
Crew health and performance is critical to successful human exploration beyond low Earth orbit. The Human Research Program (HRP) investigates and mitigates the highest risks to human health and performance, providing essential countermeasures and technologies for human space exploration. Risks include physiological and performance effects from hazards such as radiation, altered gravity, and hostile environments, as well as unique challenges in medical support, human factors, and behavioral health support. The HRP utilizes an Integrated Research Plan (IRP) to identify the approach and research activities planned to address these risks, which are assigned to specific Elements within the program. The Human Research Roadmap is the web-based tool for communicating the IRP content.

The Human Research Roadmap is located at: https://humanresearchroadmap.nasa.gov/
