Living and Working in Space: Life on the ISS
A Typical Day on the International Space Station
Keeping their physical and mental health in mind, astronauts on the International Space Station (ISS) follow a carefully planned schedule that closely mirrors a typical day on Earth. Each astronaut is accorded 8.5 hours of sleep and 2.5 hours of physical exercise each day. This physical routine also includes an additional half-hour dedicated to hygiene post-exercise. Since the absence of natural day-night cycles in space can confuse the human sense of time, the space station operates according to Greenwich Mean Time to maintain a consistent time structure.
Eating in Space
The manner in which astronauts consume food in space is quite distinctive due to zero gravity conditions. Foods are mostly dehydrated and stored in vacuum-sealed pouches. They are rehydrated with a water dispenser before eating. Astronauts also have thermostabilized meals which are heat-treated to destroy harmful microbes and enzymes. Aquatic foods such as shrimp are thermostabilized, so they can be eaten straight from the pouch.
Sleeping in Space
When it’s time for sleep, astronauts need to adjust to a completely new environment where they can’t lie down or feel the pressure of a mattress. To sleep, astronauts will often fasten their sleeping bags to the wall or ceiling of their small, personal quarters to stop themselves from drifting around. The station is never completely dark, nor is it silent, so astronauts use eye masks and earplugs to simulate night-time and block out constant noise.
Working in Space
Astronauts have duties such as maintenance work, research experiments, exercise, connecting with the public through outreach, and participating in media interviews or conference calls. They also participate in spacewalks to conduct experiments that require the unique conditions of space or to repair, maintain or upgrade the space station.
Health and Hygiene in Space
Hygiene in space is challenging due to the lack of gravity. Astronauts use specially designed devices for brushing teeth or bathing. Water doesn’t flow in space, so astronauts use a waterless shampoo and a specially designed squeeze bottle for washing their bodies. Toilets on the ISS use airflow to direct waste into containers, which are eventually sent back to Earth for disposal.
Adapted Technologies and Methods
Astronauts use a variety of technologies to adapt to life in space. For instance, rather than traditional pens that rely on gravity to feed ink, they use specially designed space pens that use pressurized gas. Cutting-edge technology also aids astronauts in conducting scientific research. For example, the ISS is equipped with a glovebox—a sealed container equipped with gloves—which allows astronauts to conduct experiments involving potentially hazardous materials without risk of contamination.
Functioning in a zero-gravity environment
Functioning in a zero-gravity environment requires novel solutions to everyday tasks and challenges. Astronauts have adapted physical workouts to maintain muscle strength and bone density in the absence of gravity. They use resistive exercise devices that simulate the effect of gravity and allow them to “lift weights” in a weightless environment.
Understanding the Role of the International Space Station
The International Space Station (ISS) is more than a hub for scientific experiments and research. It stands as a symbol of human ingenuity, adaptability, and our unwavering spirit for exploration and discovery.
