Observatory Puzzles, Their Options, Their Solutions

Observatories will always have the same flavor text and puzzle together, and are generally solved by following the pattern of rotation:
The solution for the Gek Observatory puzzle 2 is obtained as follows:
9183 - 1839 - 8391 - ****
Since 9183 becomes 1839, you should take the left-most digit and place it to the right, so 1839 becomes 8391.
This is called a rotation to the left.

Gek Observatories

Puzzle 1

Puzzle 5

---

Flavor Text:

Details of past cargo dealings are found on the terminal. The trader who once manned this place must have also used it as a storage room. The trader was also scanning for something in the cosmos. But what? A blinking beacon on the monitor could hold the answer, but first I must send the correct response.

Puzzle: 3941 - 9413 - 4139 - ****

1. 1394
2. 3149
3. 9134

Entering the correct code will yield the text:

Puzzle 6

---

Flavor Text:

The trader that once manned this station seems to have been more concerned with commerce than the discovery of new worlds, leaving the observatory to scan the stars in its absence. A beacon, received years ago, flickers with unceasing persistence on the screen, awaiting the correct response to reveal its origin. Now I must attempt to decipher it.

Flavor Text:

The observatory does not get a response from the infinite and unimaginable space above it.

I am quite alone." "A beacon flickers on screen, received from a distant point in space.

and incorrect:

There is no response. The beacon's origin remains unknown.

Puzzle 3

---

Flavor Text:

The observatory's sterile, functional layout suggests its former overseer could have been electronic in origin. Judging by the decades-old beacon flashing on screen, this entity left this place long ago. Perhaps if I can decipher the code I can learn where the beacon originated?

1. 2916
2. 6192
3. 1962

Entering the correct code will yield the text:

Puzzle 4

---

Flavor Text:

The image of the observatory's former electronic overseer flickers on the console next to the flash of the beacon indicator. I wonder how long it waited to receive such a signal from an unknown part of space? Perhaps I can send the reply the overseer never could. But first I must decipher the code.

and incorrect:

There is no response. The beacon's secret remains unknown to me.

Puzzle 5

---

Flavor Text:

The facility is more like a science lab than an observatory, the star gazing equipment sitting amidst a sea of advanced experiments. Perhaps the former custodian was too preoccupied to notice the beacon blinking invitingly on screen. If I can work out the code, I'm sure I can decipher its origin.

Puzzle: 4366 - 3664 - 6643 - ****

1. 6436
2. 4663
3. 3643

Entering the correct code will yield the text:

I punch in the numbers but the beacon does not divulge its secret.

Puzzle 6

---

Flavor Text:

As I stand at the terminal tiny drones go about a series of perfunctory cleaning routines within the pristine observatory. Clearly the former overseer was a stickler for cleanliness but less conscientious about monitoring incoming communications from distant reaches of space. A beacon blinks invitingly on the monitor. If I can enter the correct access code perhaps I could make a valuable discovery.

I discover a location within the distant stars.

and incorrect:

The observatory remains dormant. The beacon does not respond.

Puzzle 2

---

Flavor Text:

Images of shattered Sentinels are displayed like trophies on this terminal screen. Seems the observatory's former overseer had a penchant for hunting these machines. Perhaps their time would have been better spent monitoring incoming beacons like the one that flashes on a monitor before me. If I can enter the correct access code perhaps I can discover where it originated from.

Puzzle: 4634 - 6344 -3446 - ****^[sic]

1. 4463
2. 6344
3. 4634

Entering the correct code will yield the text:

The observatory hums into life as the location of a new world is displayed on the screen.

The observatory remains dormant. No new locations are revealed to me.

Puzzle 3

---

Flavor Text:

Judging by the imposing size and weapons shown on the identification ID image that glares at me as I boot up the system, the station's overseer must have originated from a warrior race. The lifeform probably left long before the arrival of the beacon that now winks tantalisingly next to it. If I can enter the correct code perhaps I can learn its secrets.

Puzzle: 5920 - 9205 - 2059 - ****

1. 0592
2. 5920
3. 2059

Puzzle 4

---

Flavor Text:

Images show that this observatory was once a warzone. Mangled metal, scorched walls and the heavily decayed corpses of a dozen hulking lifeforms betray a brutal firefight. Now repaired, whatever transpired it must have happened before the beacon that flashes on screen arrived. Perhaps if I enter the correct code I can decipher it.

Puzzle: 3987 - 9873 - 8739 - ****

1. 7398
2. 3987
3. 9873

Entering the correct code will yield the text:

Thanks to its recent repairs the observatory still functions. It leaps into life as I enter the digits, showing the location of a new destination deep within the cosmos.

and incorrect:

Perhaps the observatory still needs repairs, or perhaps the code I entered was incorrect. For whatever reason, I fail to decipher the beacon.

Puzzle 5

Vy'keen Observatory Puzzle 5 is the only exception to the general rule of solving Observatory puzzles, as it requires rotating the numbers to the right as opposed to to the left.
Flavor Text:

The heat within the observatory is oppressive, caused by the banks of powerful additional power units beneath my feet used to boost this facility's signal - and to receive others from distant worlds. I'm distracted by a beacon that flickers on a nearby monitor. If I can work out the access code, perhaps I can decipher it.

Puzzle: 7771 - 1777 - 7177 - ****

1. 7717
2. 7177
3. 7771

Entering the correct code will yield the text:
