Walking to Aldebaran

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 sent out to explore 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.
