Studying the impact of space travel on the body in Antarctica | 7.30

Key Concepts:

• Antarctic expeditions as analogs for space missions
• Physiological and psychological challenges in extreme environments
• Wearable biosensors for monitoring expeditioners
• Hypobaric chamber for hypoxia training and space simulation
• Importance of psychosocial factors in mission success
• Tasmania's role in space medicine and astronaut training

Challenges of Antarctic Expeditions:

• Environmental Extremes: Periods of darkness, blizzards, extreme isolation in one of the most remote places on Earth.
• Physiological Impacts: Lack of vitamin D, disrupted circadian rhythms due to constant darkness, leading to fatigue and cognitive impairment.
• Cognitive Effects: Memory lapses and other cognitive changes are common due to the harsh conditions.

Monitoring Expeditioners:

• Wearable Biosensors: Used to track physiological variables such as heart rate, temperature, heart rate variability, and position.
• Medical-Grade Data: Provides vital information to help expeditioners during long winter months.
• Collaboration: Study run with the Translational Research Institute for Space Health in the United States.

Antarctica as a Space Analog:

• Similar Challenges: The challenges faced by Antarctic expeditioners are similar to those faced by astronauts on the International Space Station.
• Research Focus: Cognition tests, ultrasound testing, and body morphology studies are being conducted.
• Simultaneous Research: Research is being undertaken in Antarctica and in orbit simultaneously to bridge challenges in long-duration space flight.

Tasmania's Unique Capabilities:

• Hypobaric Chamber: Unique in the Southern Hemisphere, with dual functionality to simulate depths up to 50 meters below sea level and altitudes up to 100,000 feet above sea level (or the surface pressure of Mars).
• Hypoxia Training: Doctors and nurses undergo training to recognize and manage oxygen deprivation in aviation or space settings.
• Future Plans: Plans to use the chamber for long-duration studies (up to two weeks) and to test spacesuits and equipment.

Psychosocial Factors in Mission Success:

• Importance of Mental Health: Astronaut and physician Jay Bucky emphasizes that psychosocial factors (crew dynamics, depression, stress) often end missions in Antarctica and other extreme environments.
• Consideration: Psychosocial factors should not be trivialized.

Tasmania's Role in the Space Industry:

• Growth Opportunities: Tara Martin highlights opportunities for Tasmania in astronaut training and spacesuit testing.
• Expertise: Tasmania has existing expertise in Antarctic research and medicine that can be leveraged for the space industry.
• Training Facility: Potential to develop a facility to train people for commercial and civilian space flights.

Conclusion:

Tasmania is positioned as a key player in human space flight research and training due to its Antarctic expertise, unique facilities like the hypobaric chamber, and focus on the critical psychosocial aspects of long-duration missions. The state aims to leverage its existing capabilities to support the growing commercial and civilian space industry, particularly in astronaut training and equipment testing.
