International Space Station: An overview of how astronauts live in space
This is an international space station 400 kilometers above the ground that has been circling the Earth for the past 23 years. This space station appears to be very small, but in reality, it is the size of a football stadium and weighs 420,000kg, which is equivalent to the weight of approximately 300 cars. The international space station is the most expensive thing ever built by human hands. This space station cost $150,000,000,000 to build. Its purpose is to show astronauts how to live without gravity, including how to get food, water, and oxygen. I'll tell you everything. Although the ISS is shaped like a football field, the majority of its components are solar panels, except for the part of the ISS where the astronauts live. That location is also as large as a six-bedroom house. The International Space Station (ISS) is traveling around the world at a speed of 27500km/h. This speed is so fast that it takes 16 rounds of the entire world in 24 hours and it has not deviated from its orbit for the last 23 years. Astronauts on the International Space Station (ISS) have only one goal in space: to experiment. The ISS contains laboratories built by the United States and Russia. In these laboratories, the astronaut tests object brought from Earth to see how they react in space. At the same time, natural phenomena entering the ground are detected by ISS and saved from significant damage. ISS is researching how to live on a planet like Mars, in addition to how to live on Earth. There are a total of six astronauts on the ISS, for whom this capsule is present.
Space Activities and Exercise
These astronauts are unable to feel their weight due to the absence of gravity,which affects everything from bathing to eating and drinking. They don't get any sensation from taking a bath and lying down; instead, they push themselves to move from one capsule to another and grab and hold on to things; all of the work we do on the ground every day is done in a completely different way in space due to the lack of gravity, such as drinking water, brushing their teeth, using the restroom, and exercising. Bone loss and kidney stones are well-known issues that astronauts must deal with during extended space missions. To avoid these issues, crew members exercise for 2.5 hours per day, six times per week (15 hours per week) while in orbit. Similarly, there is undoubtedly a bath in space, but it is devoid of water. They have a special type of shampoo and soap that do not require water to be applied to the body; only the shampoo is wiped away with dry towels. Apart from research and experimentation, these astronauts' jobs also include taking care of the International Space Station (ISS). If they need to go outside the space station to do some work, they must wear a spacesuit because there is a 250 degree hot and a minus 250 degree cold in space at the same time. If the sun's rays strike the human body, the human body can be burned, and if the sun is not present, the human body can be frozen.
Space food
6 astronaut food items last for 6,7 months, i.e. a total of 3780 meals for 7 months is made and delivered in ISS, but it costs $10,000 to deliver only 1kg of food to ISS. There is no chief who prepares their food. NASA food scientists are responsible for this work. The challenge for NASA food scientists is to prepare food that is light in weight and can be stored for 7 months without the use of a freezer, as well as food that contains all of the necessary nutrients. After cooking, this scientist refrigerated the food using freezer drying machine technology, which removes 97 percent of the water and restores the weight of the food. All of the food is packed into a single parcel and sent to module Cygnus, from which parcel is sent to space. When it comes to water, the astronauts living on the ISS use only 1% of the water available.
There is a high-tech water recycling technology system in the ISS that filters thewastewater and makes it drinkable. Astronauts in space use synthetic oxygen. According to NASA, oxygen is made in space through electrolysis, which is when electricity from a solar panel is passed through water and oxygen is removed from it.
