17-year journey worth US $ 150 billion to build ISS

The International Space Station (ISS) project, which started in 1998, is the most complex combination people have ever built and is a symbol of cooperation between scientific powers.

From 1998 up to now, this project has cost up to 150 billion USD, tens or even hundreds of times more than other large-scale projects such as the 5 billion USD LHC large particle accelerator, skyscraper 2 billion USD The Shard in London.The station volume is about 419.454kg, the size of 227 cars.The station also has a high speed of movement, about 23 times the speed of sound, allowing it to fly to the Moon and return to the day.

The first building block was sent to space with a length of 12.6 meters, a diameter of 4.1 meters and a volume of 19,323kg. The name of this block is Zarya , which means "dawn" in Russian.It was launched into space on November 20, 1998 from Baikonur Cosmodrome, Kazakhstan.The initial use was to supply electricity, communications and control functions, currently used as storage and launchers.

Unity's first connecting division specializes in transporting the liquids and gases needed for the Habitat Support and Control System.It can recycle astronaut urine into clean water and provide about 5kg of oxygen per day.It started to be used on December 4, 1998.The astronauts began their first space trip on December 7, 1998, with the mission to connect Unity to Zarya.

Zvezda is the first living area on the space station, 13.1 meters long, 4.1 meters in diameter, weighing 19,323kg, and put into use from July 12, 2000.It has a treadmill, a cycling machine and a freezer.It is still the center of Russia's station section.

The first crew consisted of an American astronaut (Bill Shepherd) and two Russians (Sergei Krikalev and Yuri Giokenko) flew to ISS on November 2, 2000.

Named Destiny (Fate), this is the first American laboratory block on the space station, posted on February 7, 2001.It measures 8.5 meters long, 4.3 meters in diameter, weighs 14,515kg.Currently, it is still the place to conduct major research on ISS.

The new Quest connector was put into use on July 12, 2001, 5.5 meters long, 4 meters in diameter, weighing 9.923kg.It allows American and Russian astronauts with two different outfits to make trips outside the universe easier.Earlier, only Russian clothing could go directly into space from the station.America had to go through the spacecraft entrance attached to the station.The first pizza was also taken out of space at this time.This is Pizza Hut's pizza, Salami dried sausage is used instead of pepperoni sausages to ensure no damage due to long transit time.Salt and spices are also added more, because the time spent in space reduces the taste of food.

Pirs is a mooring place for Russian spacecraft, which was put into use on September 14, 2001.It is 4.9 meters long, 2.6 meters in diameter, weighs 3,838kg.It is planned to be dismantled from the station and completely burned during the fall back to Earth's atmosphere in 2017. Russia will replace it with a multipurpose laboratory called Nauka.

A tragedy occurred on February 1, 2003, killing 7 people. Columbia had a problem when a piece of insulating foam fell off and stuck to the left wing.The ship then crumbled when it flew into Earth's atmosphere.This tragedy interrupted the US shuttle program for two and a half years.The construction of ISS was also stopped.

This is the work of the Italian Space Agency, used from October 23, 2007. It has a length of 6.7 meters, a diameter of 4.3 meters, weighs 14,768kg. Thanks to Harmony , the living and working space on ISS increased by 20% (from 420m ³ to 500.3m ³ ).The connecting corridor is used to make research laboratories.The name Harmony comes from a naming competition in 2007. There are also a number of connecting and observing departments, supporting experiments that have been posted on ISS in recent years.
