International Space Station

Whilst waiting for the summer storms to turn up, some of the PWL team like to head out and capture the many interesting things that can be see in the night sky. Anything from stars, comets, meteors and aurora’s are on the menu. But lets start with satellites…

The International Space Station (ISS) is a space station, or a habitable artificial satellite in low Earth orbit. It is a modular structure whose first component was launched in 1998. Now the largest artificial body in orbit, it can often be seen at the appropriate time with the naked eye from Earth. There a number of apps and websites that can tell you when and where the ISS will pass over (see below) and it often passes right over Perth.

The image above is just one of many that astronaut Chris Hadfield took as he orbited around the earth in the ISS.

The ISS travels at an average speed of 27,724 km/hour, and completes 15.50 orbits per day, with a with a minimum mean altitude of 330 km and a maximum of 410 km.
