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.
처음에는 시속 수백km까지 감속을 했는데, 그 근접비행을 성공시키는데 무려 7시간이 걸렸습니다. 그리곤 218kg의 연료를 사용했죠. 무척이나 피곤한 7시간이었습니다. 왜냐하면 당시, 2007년엔 로제타의 추진쳬계에 누수가 있었고 한 부분을 완전히 차단하여 애초에 견뎌내라고 설계되지 않았던 압력 아래 가동되고 있었습니다.
