Introduction
When hurtling around the Earth at a mind-boggling speed of 17,100 mph, the concepts of day and night become quite different. In a typical 24-hour period, an ISS astronaut witnesses the sunrise and sunset a total of 16 times! Human bodies didn't evolve for such conditions, so to prevent the crew from experiencing permanent jet lag, a regular 24-hour Earth day is maintained on the station. This ensures their circadian rhythms stay in sync. The day usually runs from 6 am to 9:30 pm, pegged to Coordinated Universal Time (UTC), which is essentially the same as Greenwich Mean Time (GMT).
Maintaining a Sense of Time
Lights go on at 6 am, even though the astronauts are still in their sleeping bags. These sleeping bags are affixed to the walls of their small cabins to prevent them from floating around. Before starting their day, the crew members catch up on emails, check the news online, or review any overnight mission updates sent from mission control. Even in space, staying connected to the world is important!
Morning Routine
In our everyday lives on Earth, taking a refreshing shower is a part of our morning routine. However, in space, things work a little differently. Astronauts don't have the luxury of hopping into a shower. Instead, they use a pouch of warm water and a trace of soap to rub themselves down with a washcloth. Longer-haired astronauts have a special rinseless shampoo that requires very little water. It's applied to their scalp and vigorously rubbed through with a towel. No hairdryers are needed in space! In fact, astronauts even have a specially adapted haircutting machine called the Flowbee, which prevents stray hair from floating away and causing issues with the station's hardware.
Hygiene in Zero Gravity
Toothbrushing in space is similar to the process on Earth, except for one crucial detail: there are no sinks or running water. Astronauts have to swallow the toothpaste at the end. After taking care of hygiene, it's time to get dressed. Since the temperature on board the ISS is a constant 72-73 degrees, astronauts usually wear casual short-sleeved t-shirts. There's no need for fancy outfits or sweaters. They try to change their clothes as infrequently as possible, often wearing the same items for days at a time.
Dressing Up in Space
After completing their morning routine, astronauts get dressed for the day. Since the temperature on board the ISS is a constant 72-73 degrees Fahrenheit (22-23 degrees Celsius), there is no need for heavy clothing or sweaters. Astronauts usually opt for casual short-sleeved t-shirts and comfortable pants. They try to minimize clothing changes to conserve resources and reduce laundry requirements.
Dealing with Nature's Call
Just like on Earth, astronauts need to attend to nature's call while in space. However, using the bathroom in zero gravity is a bit more complicated than on solid ground. The ISS is equipped with specialized toilets that use airflow to direct waste away from the body. Astronauts have to position themselves carefully and use straps to stay in place while they take care of their business. Waste is then sealed and stored for disposal when the supply ship arrives.
Breakfast in Zero-G
After getting dressed and taking care of personal needs, it's time for breakfast. Astronauts have a variety of food options available to them, including specially prepared meals and snacks. Food on the ISS comes in different forms, such as dehydrated, irradiated, or vacuum-sealed packages. Astronauts can rehydrate their meals by adding water and then warm them using a small onboard oven. It's not quite like a traditional breakfast on Earth, but they still enjoy a nutritious meal to start their day.
Planning and Maintenance Duties
Once the morning routine is complete, astronauts begin their assigned tasks for the day. This can involve a wide range of activities, including scientific experiments, maintenance work, or communication with mission control and researchers on Earth. Astronauts follow a detailed schedule and work in collaboration with their crewmates to ensure the smooth operation of the ISS and the completion of their mission objectives.
Scientific Experiments on Board
A significant portion of an astronaut's time on the ISS is dedicated to conducting scientific experiments. The microgravity environment of space provides a unique opportunity to study various phenomena and conduct research that is not possible on Earth. Astronauts may participate in biology experiments, physics studies, Earth observation, technology demonstrations, and more. They follow detailed protocols, collect data, and document their findings, contributing to scientific knowledge and advancements.
Gym and Workout in the ISS
Maintaining physical fitness is crucial for astronauts during their time in space. In the microgravity environment, muscles and bones can weaken over time. To counteract these effects, astronauts engage in regular exercise routines. The ISS is equipped with specialized exercise equipment, including a treadmill, a stationary bike, and resistance training devices. These workouts help astronauts maintain muscle strength, cardiovascular health, and bone density while in orbit.
Winding Down and Bedtime
As the day progresses, astronauts continue their tasks, which may include additional experiments, maintenance work, or even spacewalks. In the evening, they wind down and prepare for bedtime. Just like on Earth, getting a good night's sleep is essential for their well-being. Astronauts sleep in small cabins, securely fastened to the walls to prevent floating around. They use sleeping bags and adjustable straps to ensure they stay in place while sleeping in the microgravity environment.
Is It All Worth It?
Living and working in space is undoubtedly a unique and challenging experience. Astronauts face physical and psychological demands as they adapt to the conditions of microgravity, isolation, and a different daily routine. However, despite the difficulties, many astronauts describe their time in space as a life-changing and awe-inspiring experience. The opportunity to contribute to scientific research, explore the cosmos, and push the boundaries of human exploration makes it all worth it for these brave individuals.
