Yes. Some are in Ponish. Specifically, the hoof-written notes.
"When I got on in Sirius, all of the crew was kept in quarters, and none were allowed exit. Quarantine, I was told. Some ancient virus may have been dug up in the frozen north, and though my superiors did not believe it, they could not rule it out. Subject one was listless, rocking back and forth, and complained of strange noises. We explained to him that these noises were real, but were produced by the ship. As if an experienced sailor would not know that... Whatever is happening must cause hypersensitivity to noise.

You can't have liquid water at those temperatures. Not at that time of year. The ponies were all lined up and shot, either by their own government, or by another. I'm trusting these Stalliongraders less by the day. I would have done better to have stayed in Whitebell."
Next note:
"I fell asleep for two minutes. By Celestia do I regret it. Patient Pipette and I have holed up in the forward compartment. He has realized the tin foil delays the insanity. I dare not sleep, and I know that I too, will lose my mind if I cannot get off of this ship."
