Seeing in stereoscopic 3D
Stereo photos in the new book "Mission Moon 3D: A New Perspective on the Space Race" (MIT Press, 2018) offer a fresh look at the first efforts of the U.S. and the Soviet Union to send human explorers to the moon.
Paired images can be viewed in 3D by looking at the photos and unfocusing the eyes, fixing the gaze toward the center, according to The Stereoscopic Society.
First animal in space
The Russian stray dog Laika became the first animal in space, launched into orbit by the U.S.S.R. on Nov. 3, 1957, just a month after Sputnik 1, to prepare the way for human voyagers. Compassionate voices of protest were raised all over the world, because there was no possibility of safe return to Earth. Indeed, Laika died while imprisoned in her Sputnik 2 capsule.
