Hello everyone, I am new to this forum and it is the first time I write here. I am a physics student and I am doing my final project. I am trying to carry out a mission to Titan and Enceladus. So far, I have reached Titan, but now I need to reduce the speed and the orbit. I have seen that you have used aerobraking and aerocapture techniques in this forum. Could you help me? Thank you very much in advance
