This is a shot of Dubai's man-made 'The World' archipelago (and Palm Islands, lower left) as photographed by André Kuiper aboard the International Space Station yesterday. As you can see, it serves as a reminder that, no matter how.
What you are seeing here is the highest tennis court in the world. It is built at the top of the Burj Al Arab hotel in Dubai. The court is more than high. It was first a grass helipad but it was converted to a tennis court to help promote the Dubai Open.
