@holvek: International Space Station (ISS) is the largest inhabited scientific laboratory in Earth’s orbit, located at an altitude of about 400 km and traveling at roughly 28.000 km/h, which allows it to complete one orbit around the planet in about 90 minutes; the project was launched in 1998 and is carried out jointly by the space agencies NASA, Roscosmos, ESA, JAXA, and CSA, and since 2000 it has been continuously inhabited by crews of astronauts who stay for several months conducting experiments in microgravity—from medicine and biology to physics and the testing of new technologies for future space missions; the ISS consists of multiple interconnected modules with laboratories, living quarters, and solar arrays that provide power, and it is considered the most expensive project in human history, with a total cost estimated at over $150.000.000.000. #astrophysics #Astronomy #physics #Science
