Is The Great Wall of China Visible from Space?

The idea that the Great Wall of China can be seen from space has been around since at least 1938 and is still popular today. It certainly seems plausible that such a large, linear structure would stand out from the surrounding landscape, but it’s actually not true.

Alan Bean, the fourth man to walk on the moon, said in 1969

“The only thing you can see from the moon is a beautiful sphere, mostly white, some blue and patches of yellow, and every once in a while some green vegetation. No man-made object is visible at this scale.”

But if you can’t see the Wall from the moon, how about somewhere closer to Earth? The International Space Station (ISS) maintains a low earth orbit of between 330-435 km above our planet’s surface.

Falconry and the Tudors

When you write a book that is set in a particular period of history, it is important to get the details correct. This means that writers of historical fiction have to do a lot of research.

The first scene of Katharine Edgar’s novel, Five Wounds takes place on a hillside in sixteenth century England, where her heroine, Nan, is hoping to see her young merlin falcon make its first kill. Katharine had find out all about falconry and the Tudors – the keeping and training of falcons, and other birds of prey.

When I showed the first scene of Five Wounds to some writing friends, some of them asked a question I wasn’t expecting. ‘How rich is Nan’s family? They live in a big house so why does she need to hunt for food?’

Good question!
