Training Crew Members for Human Research on the ISS
The International Space Station (ISS) has been orbiting the Earth since 1998, and astronauts from different countries have been conducting experiments, maintaining the station, and performing spacewalks to repair and upgrade its systems. However, life in space is not all glamour and glory, as the crew also has to work hard to keep the station livable and clean.
Human Research on the ISS
One of the main goals of the ISS is to advance our understanding of human physiology and psychology in microgravity conditions. Living in space can have profound effects on the human body, such as bone and muscle loss, vestibular dysfunction, cardiovascular changes, and immune system suppression. To mitigate these risks and develop countermeasures, NASA and its partners have been conducting research on the ISS in areas such as:
- Cardiovascular health
- Bone and muscle health
- Neuroscience
- Sleep and circadian rhythms
- Nutrition and metabolism
- Behavioral health and performance
Training crew members for human research on the ISS is a crucial part of their preparation. They undergo extensive training in areas such as medical procedures, sample collection, and data recording. They also learn how to use advanced medical devices, like ultrasounds, echocardiograms, and electroencephalograms, and how to fill out questionnaires and participate in cognitive tests. Additionally, they wear sensors to monitor their activity levels, heart rate variability, and radiation exposure.
Cleaning Up after Spacewalks
Another less glamorous but equally important aspect of life on the ISS is the need to keep the station clean and tidy. For instance, after a spacewalk, which can last up to eight hours and expose the astronauts to the harsh vacuum of space, the crew has to decontaminate their spacesuits, tools, and the airlock to prevent any contamination from entering the station. They use specialized wipes, sprays, and filters to remove any particulate matter, such as dust, grease, or metal shavings, that may have stuck to their equipment or bodies.
Moreover, the crew has to manage the waste generated by the station, such as urine, feces, and food packaging, which cannot be simply flushed or thrown away like on Earth. Instead, they use a complex system of toilets, wastewater processors, and trash compactors to recycle and reuse as much as possible. This not only saves precious resources but also minimizes the environmental impact of human presence in space.
In conclusion, working and living in space is a challenging and rewarding experience that requires the utmost dedication, skill, and teamwork of the crew. Whether they are conducting human research or cleaning up after a spacewalk, each astronaut plays a vital role in ensuring the success and sustainability of the ISS and the future of space exploration.
