The International Space Station will once again be visible above the skies of Cornwall this week - weather permitting of course.

The station flies above our heads constantly, and orbits the planet every 90 minutes at a height of over 250 miles.

Of course, it's impossible to see during the day, but at night - and with the space station's orbit passing over Britain just so - it takes on the appearance of a bright star moving across the sky.

It resembles a glowing orb without the telltale flashes of an aircraft's wing drifting silently through the dark.

It goes through periods when we won't be able to see it for months, as its diagonal orbit crosses other parts of the planet, but every now and then, there comes a space of a few weeks when it flies overhead - and at night.

Times vary ever so slightly depending on your location, but we've used those given by NASA's Spot the Station website for Truro, the location it gives for Cornwall.

Here are the dates and times of when the station will become visible:

September 28

Passing over at 8.49pm, for two minutes, appearing at 33° above WNW and leaving at 54° above E.

Later passing over at 9.37pm for less than one minute, at 17° above W leaving 25° above W.

September 30

Passing over at 8.50pm, for two minutes, appearing at 26° above W and leaving at 59° above SSE.

October 1

First passing over at 8.03pm, for three minutes, appearing at 33° above WNW and leaving at 22° above ESE.

You should have no trouble spotting the International Space Station as it drifts overhead - we say 'drift', but it's actually travelling at over 17,000 mph.

You'll easily be able to spot it with the naked eye (cloud cover permitting of course), though even modestly priced binoculars may be able to pick out some of the station's details, like its large solar panels.
