Operation AXIOM: The Space Age—The 50th Anniversary of Apollo-Soyuz, Part II
17-19 July 1975: The Apollo & Soyuz capsules docked, & Stafford, Leonov, Brand, Kubasov, & Slayton shook hands, took turns boarding each other's spacecraft, exchanged flags & gifts, conducted scientific experiments, & read a statement from General Secretary Brezhnev & spoke with President Ford; after undocking, the Apollo eclipsed the Sun so the Soyuz crew could photograph the corona.

Commentary: The Apollo & Soyuz capsules re-docked after the Solar eclipse experiment, but no more crew transfers took place. The two craft were docked for a total of just under forty-eight hours.

N.A.S.A.'s "worm" logo made its debut during the A.S.T.P., as seen above on Deke Slayton's flight suit.
