""Before departure, I studied the history of mankind’s lunar probes. About half of the past 130 explorations ended in success; the rest ended in failure. This is space exploration: the danger comes with its beauty. I am but a tiny dot in the vast picture of mankind’s adventure in space. The sun has fallen and the temperature is dropping so quickly… to tell you all a secret, I don’t feel that sad. I was just in my own adventure story — and like every hero, I encountered a small problem. Goodnight, Earth. Goodnight, humanity." - Yutu"
