Nefertem system, planet 6A.
From: Commander M. volgrand.
To: Canonn Research Institute.
Subject: Investigation of derelict Generation ship Thetis.
Orbital and trajectory observations:
The generation ship is placed in a very low orbit of planet 6A, following a very circular orbit around it. This indicates an intentional stationary orbit maneuver before the crew perished.
Considering that 6A is located at about 2200ls from its parent star and that the Thetis travelled a relativistic speeds, most likely this maneuver was done in order to "stop" its movement inside this system, maybe planning for further orbital maneuvers later on. Being the Thetis a ship the size of an station, able to hold tens of thousands of human lifes, it is easy to assume that doing an orbital maneuver near an star may have been a risk that the crew was not willing to take.
As pointed out by one of my colleagues, it is as well possible that the Thetis' onboard computer emergency protocols made it to automatically establish an stable orbit as a contingency precaution.
Structural analysis of the ship:
Structural analysis shows no evidence of weapon impacts or other major damage. The presence of emergency lights over the structure are an indication that at least some energy is still being produced in the generation ship; even more, the hydroponic farms are still active and alive. This indicates that, at least, an emergency generator must be working inside the ship. A truly masterpiece of ancient technology.
Further analysis have not shown any evidence of catastrophic life support failure or internal sabotage. No poisonous products have been detected by my ship's scanners. No life signs have been detected aboard the ship.
Audio logs review:
The audio logs left by a communications officer relate how part of the population, and later the whole of it, succumbed to some sort of psychosis that made them kill their fellow colleages and families. According to the officer, this was originated in a "signal" that was originated in an "unhabited planet" the ship passed "15 light years ago". Hearing the audible sound of this signal would make anyone get into this psychotic state.
The 4th audio log shows a very rapid deterioration of the psychological state of the officer. She explains that has killed a man without knowing the real reason, and ends up saying that she "must silence them". The rapid psychosomatic and empathic deterioration may be an indication that the signal may have interfered somehow with the neurological sinapsis. However, I am no expert, and this information should be reviewed by expert neurologists and psychiatrists.
Signal origin triangulation:
Despite my best efforts it has been impossible to locate the originating planet. All systems within 15 light years towards Sol are actually inhabited already, meaning that either the signal source is not there, or it was there and has been hidden or destroyed.
Despite the most plausible theory is that the Thetis was already in orbit around Nefertem 6A when the disaster struck its crew, I must consider the possibility that the ship was still travelling when this happened. If that is the case, it is impossible to estimate the exact search area, which could range up to a 50 light years' radius. In any case, this is a very populated area of the bubble (being just over 50 light years from Sol) and I find it surprising that no other report of such... importance have been made since the humanity reached the capability to travel at faster-than-light speeds.
This leads me, once again, to the same conclussion: The original signal source is probably destroyed, if not intentionally hidden.
Recorded signal analysis:
The last audiolog seems to be a recording of the signal that has infected the Thetis communications systems. Despite the story recorded in the other logs, this sound seems to have lost the capability of affecting the mind of the hearer -it has not affected me the slightlest, neither the other many commanders that inspected the ship since it was discovered-. I cannot deny, however, that it makes me feel... unconfortable. I experienced some degrees of paranoia during my research, even coming to believe that something was aboard my ship. I recommend caution when further analysing this audio.
Find here my spectogram analysis.
I must request a further study on the Thetis. Whatever caused the death of the Thethis' crew, is something never observed before. I would like to request to send the recorded sound attached to this communication to our decryption and audio analysis experts for further research.
I'll carry on my efforts to try to locate the origin of the signal, if it is still out there.
