AST-03-175 (17-19 July 1975) --- Astronauts Thomas P. Stafford (left) and Donald K. Slayton hold containers of Soviet space food in the Soyuz Orbital Module during the joint U.S.-USSR Apollo-Soyuz Test Project docking mission in Earth orbit. The containers hold borsch (beet soup) over which vodka labels have been pasted. This was the crews' way of toasting each other.
