The International Space Station (ISS) is a remarkable spacecraft orbiting the Earth at an altitude of approximately 400 km. It serves as a one-of-a-kind laboratory for scientific research and space exploration, where astronauts from various nations collaborate. The ISS is a joint effort of five space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). It has been continuously occupied since the year 2000, making it one of the most enduring human space missions in history.
This unique facility allows for experiments in a microgravity environment, enabling scientists to investigate the impacts of space on human biology, materials science, and other fields. Furthermore, it is instrumental in preparing for future missions to destinations like the Moon and Mars.
The daily routine of astronauts aboard the ISS is meticulously organized. Typically, they wake up around 06:30 GMT and start with hygiene and breakfast. Their schedule includes maintenance work on the ISS and conducting scientific experiments. Additionally, astronauts dedicate two hours each day to exercise, which is essential to counteract the effects of living in a zero-gravity environment.
Personal hygiene aboard the ISS is managed using a specially designed bathroom that employs a suction system. Astronauts recycle sweat and urine into drinking water; however, due to a recent malfunction, urine is currently stored instead. Without laundry facilities, astronauts clean sweat with wipes and use fresh water for basic hygiene.
Astronauts often describe a distinct "space smell" that is a metallic odor encountered when space-exposed items, like space suits, are brought inside. This smell arises from radiation interacting with oxygen, leading to the formation of free radicals that generate this unique scent.
To maintain their physical health, astronauts use three types of exercise equipment: the Advanced Resistive Exercise Device (ARED) for strength training, treadmills for cardiovascular fitness, and cycle ergometers. These exercises help counteract the muscle and bone density loss associated with prolonged zero gravity.
Due to the absence of laundry facilities, astronauts wear the same clothes for extended durations. In zero gravity, clothing does not become as soiled since it does not cling to the body. A pair of trousers may be used for up to three months before being discarded in a cargo vehicle that incinerates upon re-entry into the atmosphere.
On the ISS, astronauts primarily consume reconstituted meals, akin to camping or military rations. They occasionally receive special treats from family members, and each country contributes its preferred dishes. Sharing meals is a common practice that fosters camaraderie among crew members.
Viewing Earth from 400 km above has a profound psychological effect on astronauts. Many express feelings of connection to the planet and reflect on the triviality of geopolitical divisions. Teamwork and mutual support are vital, and astronauts are selected for their ability to function effectively under pressure.
Astronauts undergo training to work cohesively as a team and are chosen for traits like tolerance and composure. When conflicts arise, they are encouraged to address issues directly and support each other through positive reinforcement.
Despite the challenges of life in space, many astronauts find it difficult to leave the ISS. They cherish the unique experience of working in space and often wish to extend their time there, considering their mission on the ISS as the pinnacle of their professional careers.
Q1. What do astronauts do during their daily routine on the ISS?
Answer: Astronauts follow a structured schedule including hygiene, meals, scientific experiments, maintenance tasks, and dedicated exercise time to stay fit in microgravity.
Q2. How is personal hygiene maintained in space?
Answer: Astronauts use a suction toilet for waste and recycle urine into drinking water. Without laundry, they clean themselves using wipes and fresh water.
Q3. What is the "space smell"?
Answer: The "space smell" is a metallic odor that astronauts notice when bringing items back from space, caused by radiation interacting with oxygen.
Q4. How do astronauts exercise in space?
Answer: Astronauts utilize specialized equipment like treadmills, resistance machines, and cycle ergometers to maintain muscle mass and bone density in microgravity.
Q5. How do astronauts cope with psychological challenges while in space?
Answer: Astronauts deal with psychological challenges through teamwork, mutual support, and the profound experience of viewing Earth from space, which fosters a sense of connection.
