a television monitor, a new Kristall furnace to replace the old one which had broken, a gamma ray telescope and food. A total of 300 items weighing 1,300 kg were delivered. The tanker also delivered 1,000 kg of propellant for the station. The Soviets revealed the propulsion problem on 16 March. They said a Salyut fuel tank was leaking fuel into the nitrogen bellows which pressurized the fuel. The station's engine systems were not affected, but valves and regulators in the pressurization system were at potential risk. Accordingly, the crew shut down the tank and used a reserve tank. The crew attempted to drain the leaking tank by rotating the station and succeeded by 23 March, purged the tank with nitrogen and closed it off. On the same day they cleared the tank, the crew used the station's shower for the first time, wearing scuba masks to keep the water out of their eyes. A milestone was reached 24 March when the cosmonauts installed a television monitor which allowed a two-way television link with ground control. For the first time, cosmonauts received television pictures in space. Seeing family, instead of just hearing them, was considered to have great psychological importance, especially as longer flights were contemplated. On 30 March, Progress 5 boosted the station's orbit, then Soyuz 32 boosted the orbit again 6 April in preparation for the forthcoming Soyuz 33 crew. Progress 5 was undocked 3 April and deorbited two days later. Soyuz 33 mission failure Soyuz 33 was launched 10 April with the fourth international crew in the Soviet Intercosmos program. Bulgarian cosmonaut Georgi Ivanov joined commander Nikolai Rukavishnikov as the craft proceeded normally towards the space station. But, as the craft approached to 1,000 metres, the engine failed and shut down after three seconds of a planned six-second burn. Rukavishnikov had to hold the instrument panel as the craft violently shook. A second firing attempt was made, but the engine shut down again, and Ryumin, observing from the station, reported an abnormal lateral glow from behind the Soyuz during the burn. Mission control accordingly aborted the mission and told the crew to prepare to return to Earth. It was the first in-orbit failure of the Soyuz propulsion system. It was only in 1983 that the Soviets revealed how serious the situation was. The craft had a back-up engine but it was feared that it may have been
