April 22 is Earth Day and is an annual celebration of the planet and to help demonstrate support for environmental movements. NASA has got involved to celebrate the planet it spends most time trying to get away from by re-releasing on of it’s most iconic images.
The Blue Marble was snapped by astronauts on the Apollo 17 mission in December 1972, who were on their way to the Moon.
The image shows Earth in all its glory, with the oceans, continents and clouds as seen from space.
NASA said in a statement: “Fifty years ago, on April 22, 1970, people around the globe marked the first Earth Day.
“On this Earth Day, as we physically separate ourselves by necessity, we can still collectively appreciate the wondrous beauty of our planet and the extraordinary science that helps us understand how it all works – and we can do it from our homes.”
The original caption from 1972 read:” View of the Earth as seen by the Apollo 17 crew travelling toward the Moon.
“This translunar coast photograph extends from the Mediterranean Sea area to the Antarctica south polar ice cap.
“This is the first time the Apollo trajectory made it possible to photograph the south polar ice cap. Note the heavy cloud cover in the Southern Hemisphere. Almost the entire coastline of Africa is clearly visible.
“The Arabian Peninsula can be seen at the northeastern edge of Africa. The large island off the coast of Africa is the Malagasy Republic.
