Launch from the Baikonur Cosmodrome; landing 36 km northeast of Arkalyk.

Following a one day solo flight Soyuz 24 docked with the space station Salyut 5 on February 08, 1977. However, the crew did not immediately enter the station, atypically having a sleep period first and delaying their entry by some 11 hours. Observers speculate that problems with fumes which may have caused the Soyuz 21 crew to leave were resolved or dealt with by the new crew. They entered the station wearing breathing apparatus and made numerous tests of the atmosphere before apparently concluding conditions were safe and removing their breathing devices.

The crew brought repairing tools and equipment for changing of cabin atmosphere. This special apparatus was designed to allow the entire station to be vented through the EVA airlock. Because of this the planned EVA was cancelled. On February 21, 1977, the crew performed an air-changing experiment, shown on TV, slowly venting air from one end of the station to the other while releasing 100 kg of air from tanks in the docked Soyuz orbital module. This was a test of the future air replenishment techniques to be carried out with Progress transports in subsequent space stations. The cabin air was not toxic, so the changing of cabin atmosphere was performed as a scientific experiment.

The crew continued the research started by the Soyuz 21 crew, performed Earth resources work, biological and materials experiments. But, being a part of the Almaz military Salyut program, other unrevealed projects were likely carried out. The flight would prove to be not only the final flight to a military Salyut station, but also the final all-military crew to be launched by the Soviets.
