facts about the international space station

The latest major pressurised module, Nauka, was fitted in 2021, a little over ten years after the previous major addition, Leonardo in 2011. The station has since been continuously occupied for 21 years and 309 days, the longest continuous human presence in low Earth orbit, having surpassed the previous record of 9 years and 357 days held by the Mir space station.

The first ISS component was launched in 1998, and the first long-term residents arrived on 2 November 2000 after being launched from the Baikonur Cosmodrome on 31 October 2000. However, continued cooperation has been rendered uncertain by the 2022 Russian invasion of Ukraine and subsequent international sanctions on Russia, who theoretically, may lower, redirect, or cut funding from their side of the space station due to the sanctions set on them.

Roscosmos had previously endorsed the continued operation of ROS through 2024, having proposed using elements of the segment to construct a new Russian space station called OPSEK. The US segment includes ten modules, whose support services are distributed 76.6% for NASA, 12.8% for JAXA, 8.3% for ESA and 2.3% for CSA. The Russian segment includes six modules. The station is divided into two sections: the Russian Orbital Segment (ROS) is operated by Russia, while the United States Orbital Segment (USOS) is run by the United States as well as by the other states. The ISS circles the Earth in roughly 93 minutes, completing 15.5 orbits per day. It maintains an orbit with an average altitude of 400 kilometres (250 mi) by means of reboost manoeuvres using the engines of the Zvezda Service Module or visiting spacecraft. It is the largest artificial object in space and the largest satellite in low Earth orbit, regularly visible to the naked eye from Earth's surface. The ISS is the ninth space station to be inhabited by crews, following the Soviet and later Russian Salyut, Almaz, and Mir stations and the American Skylab. The ISS programme evolved from the Space Station Freedom, a 1984 American proposal to construct a permanently manned Earth-orbiting station, and the contemporaneous Soviet/Russian Mir-2 proposal from 1976 with similar aims. The ISS is suited for testing the spacecraft systems and equipment required for possible future long-duration missions to the Moon and Mars. The station serves as a microgravity and space environment research laboratory in which scientific research is conducted in astrobiology, astronomy, meteorology, physics, and other fields. The ownership and use of the space station is established by intergovernmental treaties and agreements. It is a multinational collaborative project involving five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). The International Space Station ( ISS) is the largest modular space station currently in low Earth orbit. There are about three million sensors in the ISS that ensure safety and health of the space station and the crew.Station elements as of November 2021.The ISS has more than fifty computers that control the space station.You might have watched live the recent SpaceX capsule docking with ISS but do you know that at the same time 8 spaceships can be connected to the ISS.There are two bathrooms, 6 bedrooms, a gym and a 350 degree view window in the space station.The ISS is made of multiple modules and the largest ones, due to their size and weight were delivered up in the space on 42 flights.Since there is no oxygen in the space, the ISS generates oxygen for the crew by splitting water molecules in to oxygen and hydrogen gas, using the electric currents from the solar panels.After moon and Venus, the ISS is the 3rd brightest object in the sky and you can spot it in the night sky if you stare at the sky closely.The computers in the ISS have also been once hacked!.The cost to manufacturer the ISS is over $120 billion, which makes it the most expensive single thing every built.These were done for construction of the space station, upgrades and maintenance. To date, more than 230 times astronauts have done spacewalk.The ISS visitor has to work out at least 2 hours a day in the ISS or his bone and muscle starts to decrease.The ISS is 73 meters in length and 109 meters in width. To date, two hundred and forty individuals from nineteen countries have visited the ISS for experiments and research and since the year 2000 the ISS has continuously been occupied.
