Captain's log, Stardate: 4257.4
We came across a derelict vessel in an oort cloud. Sensors picked up the faint power readings. Hails produced no response, so we went into the cloud to investigate. The ship was massive, 15 km in length. A 28th century generational ship from Earth. Ancient. Built over 8 centuries ago. Due to record loss in the 32nd century, there is no recording of this ship in any database. The ship's transponder reports itself as the Hail Mary. A rather ironic name. We sent a claim beacon and are ready to enter the vessel and see if it has any inhabitants. If not, it should be a clean claim.

The ship was easily breached and no life signs were detected. Still, the ship is large and sensors can only penetrate so deep. We sent scan drones throughout the interior. No living things were found. The atmosphere is thin, barely even breathable, so all personnel wore suits inside. The farm fields in it were dead, even the soil was sterile. Trees had practically turned to stone in the cold environment. Other than that, we found no bodies. No sign of the crew.

The engineer has managed to retrieve the ship's data recordings. Apparently the crew of the Hail Mary had achieved something they called "clarity." We're not sure what that meant, but what we do know is there were no further personnel entries after that. Ship logs show that the airlocks were extensively used shortly after, on some sort of schedule. Every couple of minutes they were loaded, and then opened to space. All 17,034 passengers were summarily ejected off the ship. There is no sign of violence or damage. It appears they all entered the airlocks willingly.

The ship's doctor had a nervous breakdown. It is unclear what caused it, but he appears to be fine now.
Star date: 4262.4
Something is on the ship with us. Unknown. It has infected most of the med bay. I have closed off the hatches to lock down med bay. Those inside are of high spirits, but seem... off, somehow.
Star date: 4266.4
Everyone in the med bay has been neutralized. We're not sure if the infection has gotten out. I'm setting a priority 9 distress beacon.
Star date: Who gives a shit?
I think my head is trying to make me do something. It's trying to make my hands do stuff to me. I think. No, I can't think. Thinking is dangerous. That's what happens when you think. You'll die. I can't make my hands do what they should. I tried, but I couldn't. I have to cut them off.
