Soyuz 29 (Russian: Союз 29, Union 29) was a 1978 crewed Soviet space mission to the Salyut 6 space station.[2] It was the fifth mission, the fourth successful docking, and the second long-duration crew for the orbiting station. Commander Vladimir Kovalyonok and flight engineer Aleksandr Ivanchenkov established a new space-endurance record of 139 days.
The crew returned in Soyuz 31, which had been swapped by a crew launched in August who returned in Soyuz 29.
