Extra-vehicular activities are among the most dangerous tasks of a mission. Therefore, it is important to identify and mitigate the risks and challenges associated with them. The experiment PRESSURE by Cádiz University, Spain aims to establish emergency simulation scenarios for search and rescue missions during extra-vehicular activities. It will test emergency protocols for different types of emergency scenarios. The emergency scenarios can be distinguished into technical emergencies, physical emergencies and emergencies that involve both technical and physical issues. A technical issue could be a defect of the helmet that compromises the oxygen system, while a physical issue would be a minor leg injury of an analog astronaut. The experiment will also investigate the performance of the analog astronauts during the scenario regarding psychological, cognitive, and psychosocial aspects. In addition, it will then determine the impact the outcome of the emergency scenario has on these areas.
