Packets of Soviet space food that were flown onboard the Salyut 7 mission in 1982. Space food provides balanced nutrition for astronauts working in space, while being easy and safe to store, prepare and consume in the machinery-filled low gravity environments of crewed spacecraft. The packet at left contains a soup with pureed vegetables, at centre is a fruit yoghurt, and the packet at right contains a powder that when rehydrated becomes apricot juice with fruit pulp.
