Overview
Yuri Romanenko returned to space as commander of Mir's second long-duration expedition, launching on Soyuz TM-2 on 5 February 1987 with flight engineer Aleksandr Laveykin. Their central task was to grow the young station: in spring 1987 the Kvant-1 astrophysics module arrived but jammed short of docking on debris snagged in the port. Romanenko and Laveykin saved it with an unplanned spacewalk, clearing the obstruction by hand. Laveykin developed a minor heart irregularity and came home early in July, replaced by Aleksandr Aleksandrov, who flew up with a visiting crew on Soyuz TM-3. Romanenko pressed on alone toward a milestone, accumulating 326 days in orbit, a new world record, before returning on Soyuz TM-3 on 29 December 1987. His endurance data directly informed the medical protocols for the year-long flights that followed.
