The I.S.S. or the International Space Station is commonly known as the largest and most expensive structure ever built in space. Many people know that it was built over several years and in many different pieces. Today we will list the modules of the I.S.S. their launch vehicles, and the years when they were introduced to the space station.
Starting in 1998 the Zaraya was launched into orbit by a Proton K rocket. The Zaraya was the start of the space station, we could say it was the core. Next was the unity module and its 2 connection pieces PMA 1 and PMA 2. They were launched in 1998 by the Space shuttle Endeavour. Two years later came Zvezda. It was launched on a Proton K rocket. The month after Zvezda, Space shuttle Discovery, launched module Z1 truss and PMA 3. (Keep the Z truss modules in mind for later) A month later came the space shuttle Endeavour with the P6 truss & solar panels. These will later become one of the big solar panels.
In the year 2001 came the United States lab called Destiny on the Space shuttle Atlantis. Then came ESP 1 on Space shuttle Discovery. Next came Canadarm 2. This was a robotic arm made by Canada. It was launched by the Space shuttle Endeavour. 3 months after, came Quest, the airlock. An airlock is a room made for exiting or entering a vehicle in a vacuum. If you are exiting, it gets filled with air, then the door to the space station closes and the air is slowly released to the space station and the room is emptied of air. The door opens to space and the astronauts float out. When the astronauts come back, it's the same process, but in reverse. The quest airlock was launched on the Space shuttle Atlantis.
Now that we know how the different parts were released into space, we can see how our station looks like.
Then came Piris which was a compartment where 4 vehicles or modules could dock or connect. It was launched on a Soyuz-U. In 2002 the S0 truss was launched on Space shuttle Atlantis. It was the first piece of the solar array structure.
Next, the Mobile Base System (MBS) was launched on Endeavour. Then came the S1 truss on Atlantis. Right after, came P1 truss on Endeavour. 3 years later came ESP2 on Discovery. After a year came the P3 and P4 truss with their solar panels on Atlantis. Then came the P5 truss on Discovery. The next year came the S3 and S4 truss with their solar panels on Atlantis. Then came the S5 truss and ESP3 on Endeavour. Then came Harmony on the space shuttle Discovery and the P6 truss was relocated at the end of the truss.
Then came Columbus (the European laboratory) on Atlantis. The next month came Dextre which was a space robot that can be connected to the Canadarm 2, with Dextre came the experimental logistics module, they both came on Endeavour. Then came the JEM module and JEM’s remote manipulator system on Discovery. The next year arrived the S6 truss with its solar panels on Discovery and that completed the solar panels.
Then came the Kibo Exposed Facility on Endeavour. After 4 months came Poisk, a Russian module on a Soyuz-U. 6 days later came ELC-1 and ELC-2 on Atlantis. In 2010 on Endeavour came Tranquility and its Cupula. Then came the Rassvet module on Atlantis.
In 2011 came the Leonardo and ELC-4 modules on Discovery. Then on the last mission of the space shuttle sending pieces to the ISS came Endeavour and brought along the AMS-02, OBSS, and ELC-3 modules.
In 2016 came a new era and a Space X Falcon 9 brought the BEAM module. The Falcon 9 will be the only rocket that will be used from this point on so it won't be mentioned. Then came the IDA-2 module. In 2019 the IDA-3 module. Lastly, in 2020 the auditions were the Bartolomeo module, and later that year the NBA or the Nanoracks Bishop Airlock.
After a journey of almost 30 years, we have a complete space station!
I thank you for reading this post. I hope you enjoyed it and got a better grasp of how the ISS was built. Have a great day! See you next time!
