NM18-308-001 (March-July 1995) --- Onboard Mir's base block module, cosmonaut Gennadiy M. Strekalov, uses a hand held device to check the air. He stands near the table used for a great variety of activity--from eating, to chart-making, to hosting onboard press conferences. This visual was one of many shown by the Mir-18 crew at a press conference on July 18 in Houston.
