Why are human brains the biggest? We would like to inform you that human brains are not the biggest compared to other animals.
The first Earth Picture is very different from the last picture of Earth: the dissimilarities are really noticeable. The First Earth picture was taken on March 7, 1947. It was the time when a group of soldiers and scientists in the New Mexico desert saw something new and magnificent in these grainy black-and-white-photos: the first Earth picture. It is seen from height greater than 100 miles in space.
Here you can see the first picture of Earth.
Just the year before in 1946, scientists like John T. Mengel, a NASA pioneer who later oversaw the Vanguard Program, began testing with captured German V-2 rockets. Mengel conducted upper atmosphere experiments by launching the rockets into near-earth orbit. He designed and fabricated the first research nose shell to replace of the V-2 warhead and began placing cameras in the nose shell. According to NASA “Before the Small Steps Program began in 1946 using V-2 rockets to take images from space, the highest pictures ever taken of the Earth’s surface were from the Explorer II balloon, which ascended 13.7 miles in 1935, high enough to discern the curvature of the Earth. The V-2 cameras reached more than five times that altitude and clearly showed the planet set against the blackness of space. When the movie frames were stitched together, the panoramas taken in the late 1940s covered a million square miles or more at a single glance”.
Now let’s see the Last Picture of Earth that was taken last Month
This view from above the nation of Turkey looks out across the Aegean Sea, over Greece and onto the Ionian Sea where Sicily and the boot of Italy are barely visible. The sun’s twinkle on the Mediterranean waters highlight the Greek islands while clouds cloak the island of Crete. This Earth observation image was taken on April 2, 2018 by a member of the Expedition 55 crew aboard the International Space Station.
