The video discusses what a space station is and how it works. A space station is a satellite that can support human life and is used for scientific experiments, energy generation, and space monitoring. The first space station was Salyut, launched by the Soviet Union in 1971, followed by Skylab launched by the US. The International Space Station (ISS) was launched in 1998 and is the largest object ever put into space. It serves as a laboratory for research and has been in operation for over 20 years.
The ISS is a habitable satellite that orbits Earth at an altitude of 400 km and has a crew of astronauts who live and work on board. The station has no floor, and the crew uses all the walls to place equipment. The ISS has been used to study the effects of space on the human body and has helped to develop new technologies for space exploration.
The video also talks about the Gateway, a new space station that will be launched around the moon and will serve as a starting point for missions to deep space. The ISS is expected to be deorbited in 2030 due to maintenance costs.
The video also shows how to spot the ISS in the sky using a website and an app with augmented reality.
Here are the key facts extracted from the text:
1. The first space station was Salyut, launched by the Soviet Union in 1971.
2. Salyut was 20 meters long, 6 meters wide, and weighed 18 tons.
3. Salyut had a capacity for only three cosmonauts at a time.
4. The first mission to Salyut had 23 cosmonauts, setting a record for the longest time spent in space.
5. Three cosmonauts died in space due to oxygen loss during the first mission to Salyut.
6. The United States launched Skylab, a space station, in response to Salyut.
7. Skylab was 25 meters long, 75 tons, and had solar panels on the front and underneath.
8. Skylab was launched in 1973 and operated until 1979.
9. The Soviet Union launched the Mir space station in 1986, which was built in modules.
10. Mir was the first space station to be built in orbit.
11. Mir operated for 15 years, from 1986 to 2001.
