International Space Station

International Space Station


International Space Station The International Space Station (ISS) is a multinational building project that is one of the largest structures ever built by humans. Its main construction was completed between 1998 and 2011, although the station is constantly changing to install new equipment and testing. As of January 2018, 230 people from 18 countries have visited the International Space Station. Top participating countries include the United States (145 people) and Russia (46 people). Astronaut time and research time in space are allocated to space workers depending on the amount or resources (such as modules or robotics) they provide. NASA (United States), Roscosmos (Russia) and the European Space Agency are major partners in space, contributing to the support of other partners Japan Aerospace Exploration Agency and Canada Space Agency. Current plans require the space station to be operational by at least 2024, with partners discussing possible additions by 2028. After that, the space channel settings are not clearly set. It can be reissued, or reused for future space channels in orbit. Operators within the ISS are assisted by mechanical control centers in Houston and Moscow as well as a paid upload control center in Huntsville, Ala. Some international equipment control centers support the space station from Japan, Canada and Europe. The ISS can also be controlled from mechanical control centers in Houston or Moscow. The space station travels at an altitude of 248 miles (400 km) above the Earth's surface. It rotates around the globe for 90 minutes at a speed of about 17,500 mph (28,000 km / h). In one day, this channel travels the distance we could take from Earth to the moon and back. The space station can contrast with the bright planet Venus in brightness and appear as a bright light moving through the night sky. It can be seen on Earth without the use of a telescope by night observers who know when and where to look. You can use this NASA app to find out when and where you can see the International Space Station location. Staffing and operations The ISS usually manages between three and six staff members (a full size of six people was possible after 2009, when station channels could not support it). But employee sizes have varied over the years. After the Colombian air disaster in 2003 that left the airline for several years, crews were as small as two people due to reduced mobility The space station also housed up to 13 people several times, but only for a few days during a change of staff or a space visit. The spacecraft retired in 2011, leaving Soyuz as the current way to bring people to the ISS. Three astronauts flew to the Soyuz airport and spent about six months there at a time. In some cases, the length of the equipment varies slightly due to spacecraft arrangements or special events (such as one-year crew who were stationed between 2015 and 2016.) crews need to clear the station, they can return to Earth and ride in two Russian Soyuz cars parked on the ISS. From 2019 or 2020, commercial vehicle vehicles Dragon (with SpaceX) and CST-100 (via Boeing) are expected to increase ISS staff numbers as they could bring more commercial vehicles are available, the demand for Soyuz will decrease as NASA will buy a few seats from its Russian airspace. Astronauts spend most of their time on the ISS doing research and care, and at least two hours each day are assigned to exercise and personal care. They occasionally make space roads, do news / school access events, and post updates on social media, as did Canadian astronaut Chris Hadfield, ISS chief, in 2013. (However, the first astronaut who tweeted the space was Mike Massimino, who did it in space in May 2009.) The ISS is a long-term research platform human health, paid for by NASA as a keystone to allow people to explore other areas of the solar system such as the moon or Mars. Human bodies are subjected to microgravity, including the modification of muscles, bones, cardiovascular system, and the eyes. (Eye problems are of particular concern to the organization, as the cause is not yet clear and astronauts are reporting endless changes in vision after their return to Earth.) testing commercial products - such as an espresso machine or 3D printers - or conducting biological experiments, such as mice or plants, that astronauts can grow and The staff are not only responsible for science, but also for maintaining the channel. Sometimes, this requires them to try on space roads to fix it. Occasionally, this adjustment may be urgent - as if part of the ammonia system failed, which occurred several times. Atmospheric safety procedures were changed after a potentially dangerous incident in 2013 when the space shuttle Luca Parmitano was flooded while working outside the station. NASA is now responding quickly to "water infiltration" incidents. It also adds pads to the space for immersion, as well as a tube to provide additional breathing space when the helmet fills with water. NASA is also exploring technologies that could support or restore astronaut spacecraft. The current version of the channel is able to switch switches and perform other normal functions under surveillance, and can sometimes be switched on and off ". Space records The ISS has had several notable milestones in recent years, when it comes to personnel: Most consecutive days in space by an American person: 340 days, happened when Scott Kelly took part in a one-year campaign at the International Space Station in 2015-
