# In this day.

On December 7, 1972, the Apollo 17-Apollo 17 crew took this wonderful image of the planet # Earth, which was called "blue marble, blue marble," when Apollo 17 was on its way towards # Moon from a distance of about 4500 kilometers and became one of the most famous images of Earth from space. The original image was inverted but turned vertically.
In fact, this was not the first clear image of the Earth from space - similar images had already been taken, for example, the unmanned Apollo 4 spacecraft took amazing images of the Earth from space in 1967.
This iconic image has become a symbol of Earth's fragility, vulnerability, and isolation amid the vast reach of space.
