Explorer 6
From the Atlantic Missile Range in Cape Canaveral, Florida, the U.S.
unmanned spacecraft Explorer 6 is launched into an orbit around the
earth (above). 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
and was received in Hawaii after nearly 40 minutes.
The first image taken by Explorer 6 shows a sunlit area of the
Central Pacific Ocean and its cloud cover.
