Each week we scour the web for interesting and historic documents that catch our eye.

Astronauts Thomas P. Stafford (left) and Donald K. “Deke” Slayton hold containers of Soviet space food in the Soyuz Orbital Module during the joint U.S.-USSR Apollo-Soyuz Test Project docking in Earth orbit mission. The containers hold borsch (beet soup) over which vodka labels have been pasted. This was the crews’ way of toasting each other. This item is part of the collection: NASA Images.
