The first U.S. satellite to photograph the Earth is launched

From the Atlantic Missile Range in Cape Canaveral, Florida, the U.S. unmanned spacecraft Explorer 6 is launched into an orbit around the earth. The spacecraft, commonly known as the “Paddlewheel” satellite, featured a photocell scanner that transmitted a crude picture of the earth’s surface and cloud cover from a distance of 17,000 miles. The photo, received in Hawaii, took nearly 40 minutes to transmit.

Released by NASA in September, the first photograph ever taken of the earth by a U.S. satellite depicted a crescent shape of part of the planet in sunlight. It was Mexico, captured by Explorer 6 as it raced westward over the earth at speeds in excess of 20,000 miles an hour.
