MOSCOW, April 24. /TASS/. Limescale crust inside a ‘samovar’ whose service life had expired was the cause for the appearance of yellow water admixtures in the Russian segment of the International Space Station (ISS), First Deputy CEO for Space Systems’ Flight Operation and Tests at Energia Rocket and Space Corporation Vladimir Solovyov told TASS on Tuesday.
"A household cause is behind the emergence of the yellow admixtures in the water. Routine limescale crust had formed in the water-heating unit, which had reached the end of its service life. There is nothing terrible in that as we are regularly confronted with such things on Earth. The problem is solved quite easily, we will just promptly replace this unit, which cosmonauts normally call ‘samovar’ with a reserve one," Solovyov explained.
Some media outlets reported earlier on Tuesday that problems had emerged with the quality of hot water and yellowish admixtures of unknown origin had been discovered in the space station’s Russian segment. Reports stated that the cosmonauts allegedly had to use water in the US segment.
As Solovyov noted, the use of water from the American segment is prescribed in this case in the flight program.
"When routine replacement of equipment takes place in the Russian or US segment, it is absolutely normal - and this is even prescribed in the program of flights - that partners’ resources can be used. The ISS’s uniform crew also has a unified habitat," Solovyov said.
