Soyuz Landing Injury Risk Characterization (Soyuz_Impact_Risk)
Principal Investigator
Research Area:
Human factors
Species Studied
Scientific Name: Homo sapiens Species: Human

Currently, it is unknown how the current Soyuz landing injuries and accelerations relate to the new requirements levied on new vehicles. Understanding this connection will allow better quantification of the risk of injury for current crewmembers as well as allow NASA to relate this risk to the new design requirements recently enacted. The following are the specific aims for this task:
  1. Collect retrospective post-landing questionnaire data and develop an injury database
  2. Determine the occurrence of landing injuries to crewmembers
  3. Determine whether the Soyuz meets the current requirements for the Multi-Purpose Crew Vehicle (MPCV) and the Commercial Crew Program (CCP)
  4. Evaluate whether injury rates are consistent with the results of Finite Element (FE) modeling

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.
