International Space Station(ISS)
The ISS is the largest and most expensive technology that has ever been built, weighing almost a million pounds and costing approximately $160 billion to date. This high-tech technology allows its passengers to travel at five miles per second, meaning it would only take 90 minutes to orbit the Earth. It also allows up to six spaceships to be connected to the station at once. Although this technology is very advanced, it takes a lot of work to maintain. Over 50 computers control the systems on the space station and more than three million lines of software code on the ground support over 1.5 million lines of flight software code. Although these space expenditures are costly, they are very rewarding. The ISS serves as a science laboratory and because of it, we are learning more about the effects of space on the human body, both physically and psychologically.
