International Space Station: Life in Orbit

To most individuals, living in space is influenced by films and fantasy about astronauts floating freely, looking at the Earth and having a holiday without experiencing the force of gravity. The life on the International Space Station (ISS) is much more organized, challenging and scientific. Life in orbit is not a holiday on Earth; it is a strictly controlled mission, in which every hour is utilised, every system has an alternative, and each member of the crew has a great responsibility.

ISS revolves around the earth at a distance of approximately 400 kilometers with the speed of approximately 28,000 kilometers per hour. The station completes the journey around the planet, at that speed, every 90 minutes or so. This implies that the astronauts have approximately sixteen sunrises and sunsets in a day, which soon redefines the time-consciousness. However, even with all the beauty outside the window, life inside the station is constructed based on routine, discipline and being mindful of the fact that they are just counted on the fact that technology has to operate to perfection as a means of survival.

The ISS travels at 28,000 km/h, you could go around Earth in ~90 minutes

A World Laboratory

ISS is a highly complicated engineering project that has been built so far, and it is a representation of the international collaboration. Space agencies such as NASA, Roscosmos, European Space Agency, Japan Aerospace Exploration Agency, and Canadian Space Agency assembled it in orbit and took many years to complete it. The partners brought modules, technology and operations to the station, making it a real multinational outpost.

The ISS is more of a system of integrated laboratories and habitation areas as opposed to one open space, which is internal. Each module has its application: some modules are focused on research, others on life support, storage or docking spaceships. The station is constantly filled with cargo ships with food, spare parts, and scientific equipment. Long-duration missions could not be realized without these routine resupply missions.

The ISS is usually referred to as a lab, machine room and a mini-home according to astronauts. It has to operate as a combination of all three.

Gravity-free Life: Relearning the Gravity

Microgravity is the characteristic of life in the ISS. The station and its occupants are continuously falling freely around the earth, and this brings about an illusion of being weightless. The force of gravity has not gone away, it is merely countered by the rotational movement of the station.

Such environment alters the way human body and mind functions. Newcomers can usually take time to acclimatize as their inner ear has a problem with understanding movement due to the lack of the usual pull of gravity. Others are subjected to temporary space motion sickness. After some time the brain adapts and astronauts end up learning to move effectively by pushing slightly against surfaces and handrails to direct them.

Basic physical behaviors should be relearned. A pen that is thrown in the air will not fall; it will drift. Even a careless movement may blow tools off. Even to turn around, one has to think that there is no universal up or down. The direction of the orientation is based on the walls and workstations instead of the direction of gravity.

Through practice, astronauts finally acquire extraordinary space awareness, flying between modules with a sense of precision and minimum effort.

A Day by the Minute

Astronauts see 16 sunrises and sunsets every day

The routine in the ISS has an extremely elaborate program designed by mission planners back on Earth. The majority of days are scheduled at the 5-minutes increments, combining scientific work, maintenance, exercise, and communication.

A huge amount of crew time is taken up by scientific research. Microgravity experiments assist scientists in studying the behavior of fluids, the formation of crystals, the growth of plants and the change of the human body in space. The uses of this research are in the fields of medicine, as well as materials science.

Maintaining is also important. The ISS is a complex system having thousands of parts which need to be monitored and repaired every now and then. Astronauts will change filters, examine electronics, upgrade software and examine safety systems. Maintenance is prevented since little problems can grow in space very fast.

Workout: A Health Care Requirement

Exercise is one of the least glamorous and most important aspects of life in the ISS. When in microgravity, bones lose their density and muscles become weak due to the fact that they are not required to hold body weight anymore. In the absence of countermeasures, astronauts would come back to the earth with notable deteriorated physique.

To avoid this astronauts train approximately two hours a day on special equipment. In treadmills, there are harnesses which keep the runner in place and devices that allow weight to be lifted. Biking implants cardiovascular exercises.

Such habits are not voluntary. They are critical in the sustenance of health even up to six months and beyond during missions. The nature of the required discipline is a reflection of the seriousness of the astronaut health as taken by space agencies.

Eating, Sleeping, and Hygiene in Orbit

The nutrition, safety and convenience of meals taken on the ISS are planned. Food items are usually freeze-dried or put in pouches so as to avoid crumbs and spills. Tortillas are preferred to bread since they do not drop crumbs that may be floating to equipment.

Sleeping is done in small individual cabins. Astronauts keep themselves in sleeping bags on a wall to ensure that they do not drift. The absence of gravity dragging the body down makes some astronauts feel sleep to be exceptionally comfortable and others need time to adapt to this.

Hygiene is also to be adjusted. No showers are provided and instead astronauts clean themselves in rinseless wipes and special shampoos. Water is also used sparingly and recycled even the water in the air, breath, and sweat. An excellent example of closed-loop engineering is the life-support system installed in the ISS.

The Psychological Effect of the View

The view of the Earth, perhaps, is one of the most significant things about life on the ISS. The modules such as the Cupola enable astronauts to view the continents, oceans, storms, and city lights in the view of a few humans.

There is a cognitive shift that is known as the over view effect which so many of them report. Looking at the Earth as a planet with no visible boundaries and realizing how thin the atmosphere is can lead to the development of a profound sense of belonging and urgency to the planet. Astronauts have a tendency to come back with more appreciation to the environment protection and international cooperation.

The discussed view is not only poetic, but it affects the advocacy and science communication of certain astronauts following their missions.

Why Life on the ISS Matters

The existence in the ISS is not a goal in itself. It is something that is to come in the future. The station is a prototype of technologies and medical expertise required in the missions to be made to the moon and Mars. Scientists research the impact of spaceflight on the body during a long-term period and the reduction of risks.

The plant growth, water recycling, and habitat system experiments assist scientists to create sustainable living conditions outside the planet. In this respect the ISS is a laboratory as well as a training ground of the future steps of humanity in the direction of deep space.

Over 290 astronauts from 26 countries have visited ISS

Final Thought

Living in the International Space Station is full of magic and accountability. It demands technical expertise, flexibility and collaboration. At the same time, astronauts have to be scientists, technicians, and rigorous crewmen.

The images of floating astronauts are the most impressive ones that the general population links to, but the actual story of the ISS is that of persistence, teamwork, and understanding how humans can survive without the ground.

Each experience of being in the orbit takes us a step closer to more missions to the solar system. The ISS is not only a habitable place, where astronauts get to live, but it is also where humanity gets to know how to reach an extension into space.
