The International Space Station (ISS) has been in the Earth’s orbit for over 20 years, and it initiated a lot of useful experiments for the sake of science and for finding out more about how the human body behaves under zero gravity. Although five participating space agencies had been contributing to the International Space Station (NASA, the European Space Agency, JAXA from Japan, Roscosmos from Russia, and the Canadian Space Agency), not everything is fine and dandy.
Space.com writes that alarm has been set off at the ISS, most precisely at the Zvezda module on September 9. Smoke was seen, and a smell of burnt plastic was felt.
The systems returned to normal and the crew restarted their regular training
Roscosmos, meaning the Russian space agency, reveals that the systems are back to normal while the crew is back to the usual training. The crew cleared the air by activating air filters, as the Associated Press reveals.

You know what they say that everything must come to an end, and whether we like it or not, it also applies to The International Space Station. NASA’s Administrator, Mr. Bill Nelson, said that the American space agency hopes that our planet will be orbited by commercial space stations when the ISS will eventually retire from its activity.
The International Space Station is one artificial satellite that orbits around our planet extremely fast. The station zips around the Earth once every 90 minutes, as it travels at a staggering speed of 5 miles per hour. During only 24 hours, the ISS performs 16 orbits of our planet.
If you’re willing to get an even better idea for how fast the International Space Station moves through space, you must know that a simple photo shared by the French astronaut Thomas Pesquet could say more than a thousand words.
