The International Space Station's incredibly fast speed.

The speed at which the International Space Station (ISS) orbits the Earth can be quite "terrifying" for many people.

Despite being located in space, the space station can still be seen from Earth at times when it is at a low altitude.

A YouTube channel recently released a video showcasing the incredible speed of the space station's movement through space: approximately 28,000 kilometers per hour. At this speed, the space station completes one orbit around Earth every 90 minutes, and the crew living on the ISS experiences 16 sunrises and sunsets each day. Since its launch into orbit in 1998, the ISS has orbited Earth hundreds of thousands of times.

The International Space Station (ISS) orbits the Earth at an average altitude of 420 km above the ground. In terms of size, the ISS is 108 meters long. In terms of living space, the ISS is larger than a six-bedroom house.

The spacecraft that dock with the ISS also contribute to expanding the station's volume. There is always at least one Soyuz spacecraft docked with the station as a "rescue vessel," and every six months it is replaced by another Soyuz spacecraft with a new crew.

The ISS is a collaborative effort between many countries, with 15 nations currently involved in its operation. After more than 20 years of operation, the cost of the ISS has reached $160 billion, of which the United States has contributed $100 billion.

NASA is the representative managing operations on the ISS. Each year, NASA spends between $3 and $4 billion to operate the station. This is compared to only about $1 billion per year for Europe and $500 million per year for Russia.

The ISS won't stay in space forever. NASA has outlined a $1 billion strategy to bring the ISS back to Earth by 2031.

Following the ISS, other private space stations could be launched into low Earth orbit in the coming years.
