Das verlorengegangene Tvyek Cover wurde ersetzt.
Wollen wir hoffen das wir heute vom Pad kommen, sollte es erneut einen SRUB geben haben wir morgen nochmal die Möglichkeit, allerdings wird dann die 5 EVA gestrichen weil man auf jedenfall am 28.07. undocken muss da der Progress aller spätestens am 29.07. dockt. Sollte auch morgen uns das Wetter oder der Technikgott nicht zur Seite stehen wird es den nächsten Versuch nicht vor dem 26.07. geben.
Gruß Nico bis nachher im Chat
