The two Soviet crewmen for the
Apollo-Soyuz Test Project mission are photographed at the launch pad at
the Baikonur Cosmodrome in Kazakhstan on the morning of the Soviet ASTP
liftoff on July 15, 1975. They are cosmonauts Aleksey A. Leonov (left),
commander; and Valeriy N. Kubasov, flight engineer. The Soviet ASTP
launch preceded the American ASTP Apollo liftoff by seven and one-half
hours. The American and Soviet spacecraft were docked in Earth orbit for
a total of about 47 hours on July 17-19, 1975.

The Earth was small, light blue, and so touchingly alone, our home that must be defended like a holy relic. The Earth was absolutely round. I believe I never knew what the word round meant until I saw Earth from space.
