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.
Tivemos de reduzir a primeira em algumas centenas de km/h e, na verdade, isso durou sete horas e utilizou 218 kg de combustível. Aquelas foram sete horas de angústia porque, em 2007, houve um vazamento  no sistema de propulsão da Rosetta e tivemos de fechar um ramal. O sistema estava operando em uma pressão para a qual ele não foi projetado ou qualificado.
