Could Britain Ever Have Its Own Spaceport?

With the recent launch of the new US Aries rocket, I was reminded that Britain has its own space program – but of course we never had a “space base” like Cape Kennedy in the UK. However, given the number of space companies based in the Isle of Man, might the UK ever have its own rocket launch site, as seen in comic strips such as Eagle’s Dan Dare? Perhaps even on the Isle of Man?

Sadly, Ex Astris tech genius Jeremy Briggs, who wrote a piece on the British Rocket Programme for Spaceship Away (it’s in issue 12 if you would like to read it – back issues are still available) tells me the answer is almost certainly no.

The problem mainly boils down to Britain’s location on our planet. Most satellites are put into an orbit that spins with the planet and the planet spins anticlockwise looking down on it from the north pole. This spin of the Earth to the east is used by rockets to get a little extra momentum for free by launching them to the east.

Therefore you need a launch site which is clear to the east (normally ocean) like NASA’s Kennedy Space Centre or the European Space Agency’s Kourou, which both allow spent stages to fall into the Atlantic Ocean.

“Launching from the Isle of Man would leave spent stages or failed launches falling on England,” our resident boffin expands. “The UK does not have any good potential launch sites because of our geographical location – Shetland is the only likely candidate and that is very remote but even then, the Scandinavian countries would complain.

“The rocket engine test sites used for the Blue Streak, Black Knight and White Arrow rockets were Spadeadam near Carlisle and the Isle of Wight because they were accessible but poorly populated,” he continues. “There was never any suggestion that launches would take place from either of them.

“The spin of the Earth is used by rockets to get a little extra momentum for free and the most spin occurs where the surface of the planet is spinning the fastest – the equator. However, most of the equator is ocean and the land is mainly third world countries. Therefore, most of the space countries set up rocket launch sites which are as close to the equator as is possible in their own territory. This was a problem for the USSR, who also needed their site to be secret ie far away from NATO spy planes, and they ended up building in a desolate land locked area at Tyuratam instead.

“Since we didn’t have anywhere desolate enough in the UK for non-orbital rocket flight testing in the 1950s the British Empire came into play and Outback Australia was the best candidate – hence the range at Woomera, which is about the size of England. Reginald Alec Martin, writing as EC Eliot, set his two 1955 Tas books, illustrated by Eagle comics artist Bruce Cornwell, there.”

So, no spacebase near Blackpool then, although of course Britain does contribute to the ESA and British-born astronauts have gone into space. Plus, of course, private space company Virgin Galactic‘s owner Richard Branson is both British and a Dan Dare fan!
Fictional private space companies, of course, play a major part in Ex Astris…
