International Space Station pass times and details for the UK – May 2021

International Space Station UK Pass Times – The International Space Station – ISS is back over UK skies with some great evening passes during May 2021.

The ISS is the largest Space Station/ laboratory ever built! it can certainly be spotted with the naked eye at certain times as it orbits Earth at 17500mph at an altitude of roughly 200 miles.

Spotting the space station is especially easy and you don’t need any special equipment. You only need your eyes! Read the rest of this post to find out when and how you can spot the space station in May 2021.

How To Watch The Space Station

Check out the Beginners Guide to Seeing the ISS to learn how easy it is to spot sailing over and the Photographing the International Space Station.

You can also see this great guide on how to photograph the ISS with your iPhone.

All you need to know is when and where the International space station will be passing over your location. Luckily the United Kingdom (British Isles) is small enough for most of us who live there to see the ISS at the same time. Neighbouring countries can see the space station pass over at roughly the same time also.

Only bright passes are included in the predictions and the fainter, as a result less easy ones have been left out.

When To Watch The Space Station

The table below gives approximate pass times and basic information, this will help you spot the ISS as it passes over.

Only bright passes which can be seen from the UK are listed and the information is approximate. Therefore, UK Pass Times may differ by a few seconds, dependent on the observer’s location. Consequently, UK pass times may change at short notice if the International Space Station performs an orbital boost and changes its orbit. All Timings are local time.

Make sure you give yourself plenty of time, get your cameras ready and enjoy the ISS as it passes over and keep your eyes peeled for meteors, satellites and other objects too, they will be visible most nights!

Good luck and clear skies…..
