In questo Topic vorrei raccogliere una copertura il più possibile completa della EVA 76, anche se personbalmente non potrò seguirla nella sua interezza. Sono benvenuti tweet, screenshot ben fatti e spiegazioni a tema.
Ricordo che lo scopo di EVA 76 è la continuazione dell’installazionie dei pannelli fotovoltaici iROSA, in particolare il secondo pannello sul supporto 4B.
La durata dei lavori all’esterno e’ prevista in circa 6 ore e mezza.
Ecco il link alla diretta streaming di NASA Tv.
Il team completo di EVA 76.
