Windswept Valleys in Northern Africa
Expedition 40 Flight Engineer Alexander Gerst of the European Space Agency
posted this photograph of windswept valleys in Northern Africa, taken from the
International Space Station, to social media
on July 6, 2014.
Astronuats aboard the International Space Station (ISS) regularly photograph
the Earth from their unique point of view located 200 miles above the surface.
These photographs help to record how the planet is changing over time, from
human-caused changes like urban growth and reservoir construction, to natural
dynamic events such as hurricanes, floods and volcanic eruptions.
