Mission Description

Final Debriefing
It is the year 3302. Mankind is actively exploring the galaxy like never before. This new era of exploration has given us a peek into some of the mysteries of the galaxy as we've encountered object and artifacts in space that, so far, have defied explanation.

Together we've embarked on expeditions to the far side of the galaxy. We've explored the massive blackhole that occupied the center of the Milky Way. We are now engaged in the colonization of a new region of space thousands of kilo-parsecs from mankind's birthplace. We are becoming a galactic civilization.

Many explorers have dedicated themselves to visiting first-hand stars that were first discovered by Earth's early astronomers in the ancient past. The goal of the Cassiopeia Project is to find, visit and thoroughly map two of the most famous astronomical object from our ancient past.

We are on a mission to discover the current locations Tycho's Star and Cassiopeia A, two supernova remnants that should be found in the constellation of Cassiopeia but have elluded our discovery.


Cassiopeia A

Cas A, as it is known, is one of the strongest radio signals sources in the galaxy detectible from Earth.

Many believe that astronomer John Flamsteed observed the light of the Cassiopeia A supernova in 1680AD though this is widely disputed. What is known is that when NASA's Chandra X-Ray Observatory observed the supernova remnant in 1999AD it discovered a "hot point" at the center of the nebula that is likely a neutron star or black hole.


Tycho's Supernova

Universal Cartographics does have and entry for "Tycho" in it's interstellar database but a quick search of the galaxy map will show this system in the line of stars near the Orion Nebula. This cannot be the object described so thoroughly by Tycho Brahe in 1572AD.

Finding Tycho's supernova may prove to be more difficult then finding Cassiopeia A as there is no neutron star or black hole remnant, just the expanding nebula and a companion star fleeing the heart of the explosion at a velocity of four times the speed of other stars in it's vicinity.

To find Tycho's supernova we will be looking for this companion star, Tycho G.


Mission details, departure times and way points will follow. The mission is expected to commence during the first week of November 3302 in an effort to wrap things up before the beginning of the new year.


The mission announcement was entered into the galactic record on 14 OCT 3302 via Galnet News:

Freelance Report: The Cassiopeia Expedition

14 OCT 3302

The Earth Expeditionary Fleet has announced plans to mount a bold expedition beyond the Perseus Arm to find two stellar objects in the Cassiopeia constellation first noted by Earth astronomers in the distant past.

"The Cassiopeia Project differs from other expeditions," said Commander Finn McMillan. "We will attempt to locate two supernova remnants, which have yet to be found despite numerous attempts from independent explorers. Our targets are Cassiopeia A and Tycho's star."

"This is not space tourism. The expedition to Cassiopeia A will take us into an area of space referred to as the Formidine Rift, which before the advent of the frame shift drive, had a reputation as a kind of Bermuda Triangle. Few who venture into the Rift return to tell the tale."

The expedition is expected to depart from Chi Orionis in the first week of November 3302.

Mission Itinerary - Week One: Nov 5 - Nov 12 (events in the past hidden behind "spoiler" tag)
November 5th:
14:00 Galactic Time
- Commencement Ceremony at Chi Orionis. We will meet at 8 kilometers in front of Carey Terminal. At approximately 14:15 we’ll say a few words to inaugurate the mission. This will be followed by a group jump to symbolically begin the journey.

17:00 Galactic Time - Commencement Ceremony at Prism. We will meet at 8 kilometers in front of Hiram’s Anchorage. At 15 minutes into the event we’ll say a few words to inaugurate the mission. This will be followed by a group jump to symbolically begin the journey.

22:00 Galactic Time - Commencement Ceremony at 78 Ursae Majoris. We will meet at 8 kilometers in front of Rominger Dock. At 15 minutes into the event we’ll say a few words to inaugurate the mission. This will be followed by a group jump to symbolically begin the journey.

November 6th
14:00 Galactic Time -
First fleet meeting. We’ll visit Caph (Beta Cassiopeiae). Please note that this is a Federation-controlled system. Please plan accordingly. During our first week we will symbolically visit the five main stars of the Cassiopeia constellation.

November 7th
We’ll visit Ruchbah (Delta Cassiopeiae). Again: Federation controlled. Watch your six if you’re hostile to the Federation.

November 8th
We’ll meet together at Schedar (Alpha Cassiopeiae).
NOTE: There are no landable planets or starports in this system.

November 9th
We’ll visit Segin (Epsilon Cassiopeiae).

November 10th
We’ll visit Gamma Cassiopeia (27 Gamma Cassiopeiae according to the galaxy map).

November 12th
We’ll visit AR Cassiopeiae. This is the final stop before we begin to really make some distance from the Bubble.

The slow pace of the first week is intended to allow people to “catch up” and prepare for the main journey. We can modify this schedule if, as a group, it feels that we are moving too slow.

During this part of the journey please perform as many surface scans of unexplored bodies as you can. There are ‘mysterious things’ out there and who knows what we might find?

Mission Iternary - Week Two: Nov 13 - 18
Time to get clear of the Bubble! We'll be pushing to arrive in Kappa Cassiopeia by the middle of the week. I plan to hit Kappa Cas no later than Tuesday. The goal is to reach the following coordinates by Saturday, November 19th and begin the search for Tycho G. I'll try and post a video before hand explaining the exact procedure we'll be using to locate candidate systems.

What is a candidate system? This is any system near our plotted line that could 'plausibly' be Tycho G. These are "G2" class stars that lie close to where Tycho's SNR *should* be in the galaxy. hiciacit has graciously calculated the following coordinates at 100 light year intervals:

The basic plan will be this:
1. Narrow down the search to the most likely distance where Tycho G should be located. We'll concentrate on this smaller subset of coordinates first and move on to the wider range if time permits.
2. Each team member will 'sign up' for one or more of the targeted coordinates, fly to whatever system is closest to those coordinates and scan the local area on the galaxy map for every G2 class star within a 60 light year radius.
3. Commander conducting the survey will target SOL in the galaxy map and then pilot his or her ship is facing directly AWAY from SOL and grab a screenshot.
4. Said Commander will then check the navigation panel for any systems that do not appear on the galaxy map. This is a theoretical search as we are not currently aware that any such systems exist.
5. Commander will visit any G2 class system identified in step #2.
6. Commander will report the results of the search in this forum before moving to another location to repeat the process.

I fully expect this search to be fairly tedious. I am sorry. There is no easy way to do this. We'll conduct this survey until November 30th when we will then depart for the search for Cassiopeia A.

The Cas A search will follow a similar routine but should be much quicker/easier thanks to the limited number of neutron stars.

Mission Itinerary - Week Three: Nov 19 - 25

With most of the leg work done on the Tycho G search we're going to move forward onto the search for Cassiopeia A. Spreadsheet with the coordinates is here: and I've also added a page to the Tycho G spreadsheet to begin sifting through our finds.

Where are we looking?

Both Tycho's supernova and Cassiopeia A are so-called "deep sky objects" located in the constellation of Cassiopeia. Tycho's supernova remnant should be about 7 to 8 thousand light-years from Earth whereas Cassiopeia A should be between 10 to 11 thousand light-years from Earth.

We'll be working together to narrow down the actual search areas using available astronomical data, mathematical tools and Universal Cartographic's database of interstellar objects via the standard galactic mapping software available to pilots. This is a collaborative project that will only succeed if members of the community are willing to put forth a collective effort.

For now, please refer to the following chart that shows the relative positions of Cassiopeia A and Tycho's supernova viewed from Earth with the other stars of the Cassiopeia constellation:

Please note that in this image Tycho's supernova is shown as "SN 1572".

The appearance of the Milky Way supernova of 1572 belongs among the more important observation events in the history of astronomy. The appearance of the "new star" helped to revise ancient models of the heavens and to speed on a revolution in astronomy that began with the realisation of the need to produce better astrometric star catalogues (and thus the need for more precise astronomical observing instruments). It also challenged the Aristotelian dogma of the unchangeability of the realm of stars.

Cas A was among the first discrete astronomical radio sources found. Its discovery was reported in 1948 by Martin Ryle and Francis Graham-Smith, astronomers at Cambridge, based on observations with the Long Michelson Interferometer. The optical component was first identified in 1950.

I've been following your campaign to find Cassiopeia and Tycho. This is a noble effort and a different slant on exploration to what we've seen in the past, count me in :)

Thanks Commander! I'm going to need all the help I can get ... especially on the organizational aspect. Due to my rather odd work schedule I won't be online for any 'social' aspects of the expedition so I'll likely be absent for any weekend meetups that might take place among those who decided to participate. If you know of anyone who might be willing to volunteer time to handle 'fleet rosters' and any other mission aspects ... I'd greatly appreciate it.
I'm in too, sadly i cannot volunteer to handle the social aspect of the expedition, i'm with you guys to tag along and add additional protection.
Glad to have you along. We've got two weeks or so to plan this out. I'm thinking of heading out myself on November 1st (I work weekends so Tuesday is my day off). Maybe having the majority of the expedition depart on Saturday November 5th. Hopefully we'll have narrowed the search zone to something reasonable before then.
Cool, when i was trying to triangulate 3 stars from each of the 3 constelations in the latest Cobra clue i couldn't find Cas A.

I even sent info to my friend who works for ASKAP in australia Dr Lisa Harvey Smith.

I asked her what we may expect to find in 1000 yrs time and where to find it.

She is looking into it but isn't sure of how the game would deal with the coordinates and a supernova.

Im hoping she gets back soon with some theory, she is quite busy setting up the ASKAP and doing talks and events on Astronomy etc.

She did say the game looked very interesting though.
A fascinating project; and with FD on board there's sure to be something to find out there. I think it's optimistic to expect the mission to be completed by New Year though, even if you recruit a thousand pilots.

I'm currently heading back to the Bubble from Jaques to fit a Fighter Bay to the Pourquoi Pas? after the Guardians release, and more importantly to accept my promotion to Elite explorer. After that I hope y'all won't mind if I tag along—

I love it. This is exactly the kind of thinking that is needed to resolve this issue. Applying real-world data to solve the problem.

Elfino has asked that we add the following system as waypoints for the mission itinerary:

A trip to Formidine

Hi, although my nick is Elfino, I'm commander Kimanuel in the game (I have to change that if I can, and use here my CMDR name). I am member of Corsarios de Heimdal, a Spanish speaking clan. Thanks to his members: Xpi2, Aken, TCAS, Galactic Thor, Nyra... and allied members like Kancro Vantas.

While travelling to Jaques Station and listening to music (fast travel, no exploration at all), I started to think about Formidine again.

Some months ago I went there, exploring some areas with the surname GL-A, RO-C, TI-N... and so on. I tend to think that all these misteries, if they are well-conceived, are so elegant that when you finally discover what the mistery was, you think... Well, it was so easy and nobody saw that! Nobody had seen the elephant in the room! Anyway I also recognize that cryptography bores me, so I prefer that kind of smart enigmas.

I started to look for information about stars in the constelation of Cassiopeia. I saw a relation of them with their different names (you know, HIP and so on), and I saw that Rho Cassiopeia had, in one of those catalogues, the number 7. I started to investigate about that kind of catalogue, the name "Flamsteed" appeared. And it was a Catalogue created by the first Astronomer Royal, John Flamsteed, that started his work in the Royal Greenwich Observatory in London.

At this moment the visit that senator Kahina made to London through Cambridge Spaceport came to my mind. Perhaps there is a relation in all this... all the people has pointed that Cassiopeia A (the number 3) has dissapeared in the game, but I've never read an observation about the fact that Rho has the number 7. You know, the seven veils and that stuff. :p Ah, by the way, it's thought that John Flamsteed was the first discoverer of Cassiopeia A. And then in 1948 was found as an astronomical radiosource in Cambridge.

In the sentence "Good luck, and ... Right on, commander." the second part of the sentence has been identified many times with "Rho Cassiopeia". But, what about the first part? Well, as you can imagine, I started to look for GL-A systems near Rho Cassiopeia. And then this happened:

Well, it's pretty graphic. The stars HYPHEEG GL-A C3-, HYPHEEG GL-A C3-2, HYPHEEG GL-A C3-1 are aligned, just like three dots ... Sorry for being so obvious :D Edit: Distance from Rho Cassiopeiae to Hypheeg GL-A C3-2 = 830,39 ly.

Anyway I was arriving at Jaques Station, so I had to delay that. After exploring a sector for one week as part of the Colonia Nebula Project and painting my ship in red; I returned to the bubble, prepared my ASP Explorer "Rocinante" for the trip and left.

I have to say at this moment that I had been reading a bit more while exploring. The area of the GL-A asterism ( was adjacent to Cepheus constellation, in a confluence of many sectors, which can help hiding a place (QIEDAEA, HYPHEEG, GLUFOA...) and near the possible situation of Cassiopeia A, that according this post it's in the area of -10370, -385.7, -4138 .

That zone is also almost in Cepheus, a mythical king of Aethiopia, the name that greeks and romans gave to the north of Africa. Just like Kahina, queen of the same place.

Well, I explored those three stars. There's a fourth one (HYPHEEG GL-A C3-0) next to the others. The stars of two of them had been previously explored. If those three stars are the solution to the enigma, and as far as I remember, people from Frontier said that the systems we are looking for had been partially discovered.

After that I started to explore the area. My objective was the three following systems, that are placed exactly between Rho Cassipeia and the Hypheeg GL-A family. They are HYPHEEG UX-B D0, UX-B D1 and UX-B D2. No luck, except an ammonia world.

I started exploring the area and I found another 3 ammonia worlds. I have the theory that we are exploring something extense, perhaps the original (7?) ammonia worlds where the thargoid invasion started, and a human space station for research. But I just saw four. There are two earthlike worlds too, in this area:




HYPHEEG PL-C C1-0 – Hi Erimus, you had discovered it previously :D

I don't know if there's something hidden in the area. Perhaps those three stars (remember, there's a fourth one) are the best worst red herring I've ever seen.

I had another idea. I looked in the center of the line between Rho Cassiopeia and the GL-A family. But I could think of GL-A as a mirror. That way, we would look for a point situated at the same distance to GL-A that Rho, but in that same line. The point is -104356, 687, -4485. There are not stars there and is an area too high (excesive distances) to be reachable when the game was gamma. I have to say anyway that the prism 10x10 corresponding to that point has no stars in the positive Y axis.

And well, I'll do a fast visit to Mars High. I have to test some ideas.
Elfino has asked that we add the following system as waypoints for the mission itinerary:

Thanks Jaiotu. I don't know which coordinates you are going to explore. But if the ones I have for Cassiopeia A are right, that are -10370, -385.7, -4138 -I didn't make the calculations myself-, and considering the center of the line GLA to Rho: -10461, -503, -4894 , the distance between those two points is 770 ly. Well, it's up to you. Good luck commanders.

I am intrigued by this expedition, It's nice change to look for something clearly defined in broadly specified area for a change with no unhelpful terrorists involved :) .

I am willing to help with anything you need (just name it, beer, cookies, hit squads...) but I have no experience whatsoever with anything community related. I hope I'll be able to get my AspX set up for exploration in time, but I need to get new mission runner ship first so I can rebuild my Asp. Plus I need to get hang of this new fancy discovery tool kids talk about these days ( back in the old days we had just a map without route-planner and we liked it... :) )
