[1] The crew visited Vladimir Kovalyonok and Viktor Savinykh, who had reached Salyut-6 ten days prior.

On 24 March, the cosmonauts installed cosmic ray detectors in the station's work and transfer compartments.

On 26 March the cosmonauts performed the Illuminator ("viewing port") experiment, which studied the degradation of the station's viewports.

On 27 March, Vladimir Kovalyonok and Viktor Savinykh of the resident crew used the Gologramma ("hologram") apparatus to image a viewing port damaged by micrometeoroids.

They repeated this experiment the next day, when they also collected samples of the station's air and microflora and removed the cosmic ray detectors for return to Earth.
