Shutters that give protection to the pane when or no longer it is rarely in exercise absorb been opened to permit the cleaning. When done, the shutters absorb been closed once more.
Ryzhikov and Zubritsky then returned to an experiment they installed in the route of the earlier
The spacewalkers then inserted a replacement cassette into the Ekran-M and, no topic attending to exercise wire ties to defend it in location, mission control reported getting correct information. The older cassette will almost certainly be returned to Earth for prognosis.
