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. Roscosmos has endorsed the continued operation of ROS through 2024, having previously proposed using elements of the segment to construct a new Russian space station called OPSEK.
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 many other nations. 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, an American proposal which was conceived in 1984 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 a modular space station (habitable artificial satellite) in low Earth orbit. The clean water will be flushed through its distribution system to remove any remaining petroleum products.Station elements as of November 2021 The Navy took this well down because it was the closest well near damaged dwelling zones, according to Pacific Fleet deputy commander, Blake Converse. The Navy said on Thursday that testing revealed petroleum in its Red Hill well, which taps into a nearby aquifer. Perl Harbor is home to one of the world's most important Navy stations, which has submarines, ships, and the commander of US forces in the Indo-Pacific region has been hit by the issue. A navy officer stated that the problem is just growing worse every day. The Navy and the state Department of Health are both looking into the source of the contamination, as per the reports of AP News. In Pearl Harbor, which is on the island of Hawaii, US, petroleum is found in tap water which has alarmed the Pearl Harbor military families. Hundreds of military families around Pearl Harbor have complained about the Navy's water system becoming tainted with petroleum.
