英文简介：My name is Gary Rendell. I’m an astronaut. When they asked me as a kid what I wanted to be when I grew up, I said, “astronaut, please!” I dreamed astronaut, I worked astronaut, I studied astronaut. I got lucky; when a probe exploring the Oort Cloud found a strange alien rock and an international team of scientists was put together to go and look at it, I made the draw.

I got even luckier. When disaster hit and our team was split up, scattered through the endless cold tunnels, I somehow survived.

Now I’m lost, and alone, and scared, and there’s something horrible in here.
