The International Space Station has orbited the Earth for the 100,000th time, announces the Moscow-based mission control centre.
The space station is situated at an altitude of 400 kilometres, travelling around our planet once every 90 minutes at 28,000 kilometres per hour. It has now made its 100,000th orbiting from 0435 to 0610 GMT.
NASA says that the ISS has travelled 4.2 billion kilometres.
This anniversary is deemed a big deal by the world of science.
“This is a significant milestone and is a tribute to this international partnership made up of the European Space Agency, of Russia, Canada, Japan and the United States,” says a flight engineer on the ISS, Jeff Williams.
The ISS has been occupied by astronauts since 2000 when Bill Shepherd (of American nationality) and Sergei Krikalev and Yuri Gidzenko (Russian cosmonauts) returned from a mission on the ISS. It still has many more years to go, according to the plans of the participating countries; the latter have agreed to finance the projects until 2024.
