The International Space Station (ISS) is a large space stationassembled and maintained in low Earth orbit by a collaboration of five space agencies and their contractors: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA(Europe), and CSA (Canada). The ISS is the largest space station ever built. Its primary purpose is to perform microgravity and space environment experiments

Operationally, the station is divided into two sections: the Russian Orbital Segment (ROS) assembled by Roscosmos, and the US Orbital Segment, assembled by NASA, JAXA, ESA and CSA. A striking feature of the ISS is the Integrated Truss Structure, which connects the large solar panels and radiatorsto the pressurized modules. The pressurized modules are specialized for research, habitation, storage, spacecraft control, and airlock functions. Visiting spacecraft dock at the station via its eight docking and berthing ports. The ISS maintains an orbit with an average altitude of 400 kilometres (250 mi) and circles the Earth in roughly 93 minutes, completing 15.5 orbits per day.

The ISS programme combines two prior plans to construct crewed Earth-orbiting stations: Space Station Freedom planned by the United States, and the Mir-2 station, planned by the Soviet Union. The first ISS module was launched in 1998. Major modules have been launched by Proton and Soyuz rockets and by the Space Shuttlelaunch system. The first long-term residents, Expedition 1, arrived on November 2, 2000. Since then, the station has been continuously occupied for 23 years and 198 days, the longest continuous human presence in space. As of March 2024, 279 individuals from 22 countries have visited the space station. The ISS is expected to have additional modules (the Axiom Orbital Segment, for example) before being de-orbited by a dedicated NASA spacecraft in January 2031.

History of international space station

As the space race drew to a close in the early 1970s, the US and USSR began to contemplate a variety of potential collaborations in outer space. This culminated in the 1975 Apollo-Soyuz Test Project, the first docking of spacecraft from two different spacefaring nations. The ASTP was considered a success, and further joint missions were also contemplated. 

One such concept was International Skylab, which proposed launching the backup Skylab B space station for a mission that would see multiple visits by both Apollo and Soyuz crew vehicles. More ambitious was the Skylab-Salyut Space Laboratory, which proposed docking the Skylab B to a Soviet Salyut space station. Falling budgets and rising cold war tensions in the late 1970s saw these concepts fall by the wayside, along with another plan to have the Space Shuttledock with a Salyut space station

n the early 1980s, NASA planned to launch a modular space station called Freedom as a counterpart to the Salyut and Mir space stations. In 1984 the ESA was invited to participate in Space Station Freedom, and the ESA approved the Columbus laboratory by 1987. The Japanese Experiment Module (JEM), or Kibō, was announced in 1985, as part of the Freedom space station in response to a NASA request in 1982

In early 1985, science ministers from the European Space Agency (ESA) countries approved the Columbus programme, the most ambitious effort in space undertaken by that organization at the time. The plan spearheaded by Germany and Italy included a module which would be attached to Freedom, and with the capability to evolve into a full-fledged European orbital outpost before the end of the century

Purpose of international space station

The ISS was originally intended to be a laboratory, observatory, and factory while providing transportation, maintenance, and a low Earth orbit staging base for possible future missions to the Moon, Mars, and asteroids. However, not all of the uses envisioned in the initial memorandum of understanding between NASA and Roscosmos have been realised.^[30] In the 2010 United States National Space Policy, the ISS was given additional roles of serving commercial, diplomatic, and educational purposes

About the International Space Station

The station was designed between 1984 and 1993. Elements of the station were in construction throughout the US, Canada, Japan, and Europe beginning in the late 1980s.

The International Space Station Program brings together international flight crews, multiple launch vehicles, globally distributed launch and flight operations, training, engineering, and development facilities, communications networks, and the international scientific research community

How many International Space Station are there in the world?

As of 2024, there are two fully operational space stations in low Earth orbit (LEO) – the International Space Station (ISS) and China’s Tiangong Space Station (TSS

How many astronauts are on the ISS?

An international crew of seven people live and work while traveling at a speed of five miles per second, orbiting Earth about every 90 minutes

How long is one day in space?

How long is a day in outer space? A day in outer space is 90 minutes long, which means that astronauts see around 16 sunsets per day. However, practically speaking, “days” don’t really exist in outer space; they only come into play when you’re on a planet

Who owns the ISS?

This means that the owners of the Space Station – the United States, Russia, the European Partner, Japan and Canada – are legally responsible for the respective elements they provide. The European States are being treated as one homogenous entity, called the European Partner on the Space Station

What do astronauts eat?

Foods such as retort pouch foods and canned foods. These can be eaten directly from the pouch or after heating in the ISS’ food warmer. Types include canned Japanese curry and fish, and yakitori (grilled chicken skewers). Thermostabilized foods from other countries include meatloaf, ravioli, and pudding

Who builds space stations?

A partnership between European countries (represented by ESA), the United States (NASA), Japan (JAXA), Canada (CSA) and Russia (Roscosmos), the International Space Station is the world’s largest international cooperative programme in science and technology

Why India did not join ISS?

ISRO had not been able to fund an Indian astronaut, even on Soyuz, since Rakesh Sharma in 1984. The ISS has only 6 seats available, shared between the US, Russians and ESA partners. Seats would have to be bought and these are not cheap. the cost of developing hardware to contribute to the ISS is extremely high

Has any Indian been to ISS?

Today, only private vehicles are available for reaching the ISS (Russia is unlikely to give a slot for India’s astronaut supported by NASA to reach ISS). It has been reported that this visit would cost India around Rs 200 crore. Rakesh Sharma is the only Indian citizen to visit the space till date

How do astronauts shower?

The astronauts wipe their body clean by using a wet towel, and wash their hair by using waterless shampoo. Since water does not flow in a zero-gravity environment, the astronauts cannot wash their hands under a faucet as you do on Earth. So, there are no sinks or showers inside the space shuttle

Is ISRO making a space station?

According to ISRO Chairman S Somanath, the Indian Space Station is in the final stages of design as of February 2024. After the first part of the project is launched successfully in 2028, humans may be sent to the station

Astronauts international space station

The International Space Station (ISS) is home to an international crew of seven people who live and work while orbiting Earth at a speed of five miles per second, about every 90 minutes. Astronauts on the ISS typically spend six to 12 months in space, and their lives are different from those on Earth due to the station’s almost complete lack of gravity. 

Here are some ways astronauts adapt to life on the ISS:

• Exercise Astronauts exercise for about two hours each day to keep their muscles and bones strong. 
• Sleep Astronauts sleep in sleeping bags or small compartments to prevent floating away. 
• Washing Astronauts wash themselves with wet towels and body wash, as the ISS doesn’t have showers, baths, or washstands. 

Astronauts’ responsibilities on the ISS include: Operating science experiments, Maintaining and repairing equipment, and Cleaning the station. 

As of September 12, 2021, 244 people have made 403 spaceflights to the ISS, including the seven crew members on Expedition 65. 

The ISS is a cooperative program between the United States, Europe, Russia, Canada, and Japan, and it’s not owned by any one country

How long are astronauts on the ISS?

Astronauts on the International Space Station, or ISS, often spend six to 12 months in space, orbiting Earth. It can be a little cramped staying inside the space station all that time

What do astronauts do in ISS?

There’s lots of work to operate the many science experiments on board. The crew also has to make sure that the station is in top shape, so they clean, check equipment, maintain and repair or replace broken equipment. Crew members also must exercise two hours each day to stay fit and keep their bones and muscles strong

How big is the international space station

The International Space Station (ISS) is 357 feet (108 meters) long, which is almost the same length as an American football field, including the end zones. It’s also about the size of a six-bedroom house and weighs almost 1 million pounds, making it 450 times heavier than a small passenger car. The ISS is a permanently crewed platform that orbits Earth at an altitude of 250 miles. 

The ISS is four times larger than the Russian space station Mir and five times larger than the U.S. Skylab. It has eight miles of electrical wiring and a 55-foot robotic arm called Canadarm2 that can move modules, deploy experiments, and transport astronauts. The ISS can also connect to up to eight spaceships at once, and a spacecraft can reach the station as soon as four hours after launching from Earth

The International Space Station, or ISS, is an orbital laboratory and has hosted more than 250 people since 1998.

Current plans call for the space station to be operated through at least 2024, with the partners discussing a possible extension. NASA has approved an extension to 2030, although Russia says it will withdraw after 2024 to focus on building its own space station around 2028. How the station will be operated after Russia’s departure has not yet been determined. After 2030, plans for the International Space Station are not clearly laid out either. It could be deorbited, or recycled for future commercial space stations in orbit.

How high is the ISS?

The space station orbits Earth at an altitude of approximately 250 miles (402 kilometers), with its orbital path taking it over 90 percent of the Earth’s population. Thanks to the size of its solar panels, it can be seen with the naked eye at dusk or dawn when flying over a local area. You can track the space station’s path near you at

HOW FAST IS THE ISS MOVING?

The ISS circles Earth every 90 minutes at a speed of about 17,500 mph (28,000 km/h). In one day, the station travels about the distance it would take to go from Earth to the moon and back

HOW TO ASTRONAUTS GET TO THE ISS?

There is typically an international crew of seven people that live and work inside the ISS. However, during the changeover of crew members, this number can vary; for example, in 2009, 13 crew members visited the ISS. This is also the record for the most people in space at one time. Occasionally, private missions such as those from Axiom Space bring non-professional astronauts on board the space station, too

Space stations in startrek series

In Star Trek, space stations are artificial structures in space that can serve many purposes, including research, defense, and starship maintenance. They can be in orbit of a planet and may be referred to by another term, such as a spacelab or outpost, depending on their purpose. 

Here are some space stations in Star Trek:

• Deep Space Nine: A well-known and iconic station that plays a central role in the series. It’s a Cardassian-built Starfleet/Bajoran space station near the planet Bajor that’s moved near a stable wormhole’s entrance. The station is multifaceted and designed to serve the needs of a diverse array of species and factions with a marketplace and recreational areas. 
• Starbase 375: A Federation space station near the Cardassian border 
• Deep Space Station K-7: A Federation K-class deep space station that serves as a resupply station and drydock in areas where there are no inhabited star systems 
• Earth Spacedock: A Federation space station with a diameter of 3.8km 

How ISS is similar to startrek space stations

The International Space Station (ISS) is similar to the space stations in Star Trek in that they are both stationary outposts that can be used for scientific research and defensive monitoring. The ISS is a large spacecraft that orbits Earth and serves as a home for astronauts and cosmonauts, as well as a science laboratory. In Star Trek, space stations like Regula I in “The Wrath of Kahn” and Deep Space Station K7 in “The Trouble with Tribbles” are used for scientific research, while Deep Space 9 is used for defensive monitoring

The ISS also has a command structure similar to Star Trek, with a commander who makes decisions in emergencies. The nationality of the commander alternates between US and Russian crewmembers. 

The ISS was one of the first internationally combined efforts to explore space, and NASA and its international partners adopted a similar model to Star Trek when conceiving it
