We had to brake the first one by a few hundred kilometers per hour, and actually, the duration of that was seven hours, and it used 218 kilos of fuel, and those were seven nerve-wracking  hours, because in 2007, there was a leak in the system of the propulsion of Rosetta, and we had to close off a branch, so the system was actually operating at a pressure which it was never designed or qualified for.
A primeira travagem foi de umas centenas de quilómetros por hora. Durou sete horas e gastou 218 quilos de combustível. Foram sete horas enervantes, porque, em 2007, tinha havido uma fuga no sistema de propulsão da Rosetta e tivemos de vedar uma derivação. Por isso, o sistema operava a uma pressão para a qual nunca fora desenhado.
