As reported by RIA Novosti with reference to the data of the crew's negotiations with the Earth, the cosmonauts did not rule out that the crack in the "Star" is "convex inward."
In addition, a color change is observed in the center of the crack.
"Such a feeling, an assumption ... a blow from the outside," Ryzhikov said.
Earlier in "Roskosmos" said that the size of the crack on the ISS is no more than 4 cm.
