Upon first entering the station, the crew encountered a smoky and burnt atmosphere and after replacing part of the ventilation system spent the next day back in their Soyuz until the air cleared. Their stay in Salyut was productive, including live television broadcasts. A fire broke out on day 11 of their stay, causing mission planners to consider abandoning the station. The planned highlight of the mission was to have been the observation of an N1 rocket launch, but the launch was postponed. The crew also found that using the exercise treadmill as they were required to twice a day caused the whole station to vibrate. "Pravda" released news of the mission and regular updates while it was in progress.
