Commanders,

After resting for about a week, I continued my brown dwarf survey yesterday, almost immediately stumbling over my first Ammonia world in such a system:

At about 41Ls from the quasi-star, this world featured a temperature of slightly over 180K.

Here's a perspective with the sub-stellar object in view as well:

This photograph has been post-processed to remove some geometric distortions.

Aside from that, I managed to find my fifth water world in a brown dwarf system today. It was dancing with an ice planet, itself having a liquid surface only because of its atmosphere excerting a pressure of over 500 bar:

Aside from that, one more gas giant with ammonia-based life has been found, but there's no picture as the planet was just to dark being over 700Ls away from the central object. With that, I can update my list of discoveries for this survey:

• Ammonia worlds: 1
• Earth-like worlds: 0
• Water worlds (non-terraformable): 7
• Water worlds (terraformable): 1
• Water giants: 0
• High metal content worlds (terraformable): 4
• Gas giants with ammonia-based life: 6
• Gas giants with water-based life: 2
• Class II gas giants: 7
• Class III gas giants: 1
• Class IV gas giants: 1
• Class V gas giants: 0

Not too bad, and I'm still under 1000 systems discovered on this survey!

Edit: Instead of making a new report for just that, I decided to edit this one. One day after writing the above report, I found yet another class II gas giant as well as a non-terraformable water world. This makes water worlds seem almost common in brown dwarf systems, with 7 found amongst about 700 systems. So that's roughly 1 in 100.

The water world was once again outside of the habitable zone, maintaining a liquid surface only by an atmospheric pressure of over 3300 bar:

The cloud layer largely obscures the liquid surface

Interestingly enough, the world appears to feature a large ice cap on one of its poles, but it's hard to confirm through the very thick and mostly opague atmosphere. Maybe it's a large storm cloud instead? But it really looks like a mass of ice...

Here's the view when looking towards the particularly dim class L dwarf:

The dwarf appears to be close, but this one is just too cool for the water planet to be within its goldilocks zone

Edit: And another Class II gas giant has been added to the list.

Edit: I've took a break for a while, but yesterday on 3305-11-07, I visited 15 more brown dwarf systems, and stumbled over yet another non-terraformable water world. Not so bad!

Edit: And another gas giant with ammonia-based life as well as a Sudarsky class II giant on 3305-11-23!

Edit: Just a day later, I managed to find another class II gas giant, and a whole three terraformable high-metal-content worlds too:

Edit: 3305-11-28, and today I surveyed about 70 class L dwarf systems. A pretty boring ride today, but there was at least one ray of light: A gas giant with ammonia-based life, sole planet of its system!

Commanders,

In my last report, I had some great news with those two terraformables in a brown dwarf system, but after that, there wasn't any such luck to be had. At least not so far.

In the meantime, I shall list all interesting or somewhat interesting/rare worlds I have found so far, after surveying about 500 such quasi-stars (it seems my previous estimate wasn't quite correct). "Rare" in this context means "rare in class L brown dwarf systems according to my survey".

The most common terrestrial planets in such systems are of course ice worlds, so those are of no interest whatsoever. Second to those are high-metal content worlds, followed by rocky planets, which are already pretty rare, metal-rich worlds being even more rare. As for gas giants, the only common ones are class I. All of those will be excluded, unless terraformable (for rocky, metal rich and high metal content worlds).

Here's my list of less common worlds found so far:

• Water worlds (non-terraformable): 4
• Water worlds (terraformable): 1
• High metal content worlds (terraformable): 1
• Gas giants with ammonia-based life: 3
• Gas giants with water-based life: 2
• Class II gas giants: 3
• Class III gas giants: 1
• Class IV gas giants: 1

So no class V gas giants so far, and no water giants either. The latter is probably understandable, as water giants are thought to form from very large water planets which are having their liquid evaporated by a hot star.

When it comes to terrestrial worlds, I am still to find an Earth-like planet as well as an ammonia world. Given how few water worlds I've found so far we can make a guess that that won't be easy though. In regular star systems, my ratio of water worlds (all of them) to Earth-like worlds was 110:9, so 12.24× as many water worlds.

As for the water world to ammonia world ratio, mine is 551:72, so 7.65× as many water worlds than ammonia ones.

It's going to be one long search. Current likelyhood that I will abort before having found an Earth-like: 90%. ;)

Edit: I'm updaing this, as I found twin water worlds orbiting each other plus another gas giant with water-based life just after having posted this, so they've been added to the list now:

The water worlds were just a bit too far from their "star", so they weren't terraformable unfortunately. The water was being kept liquid by very thick, high-pressure atmospheres.

Commanders,

For the past week or so, I have decided to survey brown dwarfs of spectral class L, so the brightest of them. Goal was to find interesting, optimally even naturally life-bearing worlds in such systems.

Aside from a gas giant with ammonia-based microbial life, I didn't manage to find anything until very recently. It took roughly 400 - 500 systems before I got there though, and it wasn't an Earth-like world, but instead of it, two terraformables within a single system, one being a high metal content world and one (almost a jackpot..) a water world!

The quasi-stellar object in this case was a class L0 V brown dwarf, so they don't come any brighter than this. It was the only one in that system as well.

Here's the brown dwarf as seen from the terraformable high metal content world:

The planet is a bit smaller than Earth at a radius of 5477km, and features a similar surface gravity at 0.96g. That's where the similarities end though. It's atmosphere is a thick and hot layer of CO₂ with some SO₂ and a pretty high surface temperature of 768K. It sits about 20ls away from its parent, and is tidally locked to it as well.

Now here's a similar view from the vicinity of the equally terraformable water world:

As you might've guessed by the apparent size of the central body, the water world is farther out then the one before. Its size is very close to Earth's at 6247km of radius. Surface gravity is 1.14g for this one and the atmosphere is very Earth-like, as it's made of N₂, O₂ and H₂O at about the same distribution as back home. It's a bit on the cool side with an average of 250K, but still, very close to optimal.

It orbits its parent at a distance of roughly 33ls. Like the high metal content world, it's tidally locked to the brown dwarf. Must make for some interesting ocean currents on the surface I assume.

Here's a view from the direction of the star, which illuminates the water world, dipping it in quite a bit of red. Makes for a very different view from the usual ocean planets, which tend to orbit much brighter and bluer stars:

So I'll count that as a pretty big success. For now, the class L survey shall continue, as I'm not yet bored of the dim red quasi-stars. Finding an Earth-like world is a bit of a goose chase, but let's see what I'll get.

Commanders,

While traveling through Odin's hold on what could be called my second exploration trip, I've come across a high metal content world in the system [Phoi Aowsy BN-A d14-10374]. The planet in question was body [AB 1].

What caught my eye on the dark brown surface of it while looking at the body in the full spectrum system scanner where some peculiar yellow spots. Made me curious enough to fly over and inspect them more closely.

Turned out to be quite interesting:

Whoa!

There were a few more of them actually

The planet featured an almost pure, thick and hot water vapour atmosphere and some large-scale silicate volcanism. Since it's very unlikely to be a weather phenomenon judging by the shape of the spots and the composition of the atmosphere, those should be a result of the major silicate vapour geysers reported on the planet. There's probably sulphur being ejected by the volcanoes together with the silicates, as some other commanders [have suggested], resulting in the intense yellow colour.

If only we could get closer to those massive objects, but unfortunately, with that thick atmosphere in the way, we cannot. At least not at the current point in time...

Commanders,

Being as fascinated with high-g landings as I am, I was delighted by FixMeNow's [report] of a 11.01g world!

When I originally read that, I was roughly 12.000Ly away from its position, but it just called to me so much.. So I prepped a few beers and just raced over there like crazy, all in one go.

To the system [Kyloall CL-Y g1518] and its new high-g record holder, body D 1:

Interestingly, all the landable very-high-g planets (≥9g) I've seen now share the same colour and hence probably also have a similar composition.

I contemplated whether it was wise to attempt a landing on such a dangerous world after a total of four beers (ugh...), but in the end I decided to attempt it despite the level of intoxication and the loss of concentration that came with it:

I seems we're reasonably far down here, but that's still 369km of altitude

As per high-g best practices, I kept my ship pointing downwards at a very shallow angle rarely under -5° and refrained from turn or roll manoeuvres, applying course adjustments purely by yaw.

At the end of the glide phase

Things went pretty smoothly, so if you can do it by the book, you can do it by the book even when drunk it seems. To make things a tiny bit more interesting, I had picked a large crater for a landing spot, thinking I'd get higher g-forces at its bottom.

Hovering just 7 metres above ground

Time for setting my arse on the ground:

Once again shieldless and flawless!

Alright, that went perfectly! The only fly in the ointment was that I was under the effect of 10.99g, not the promised 11.01g. Probably because I hadn't picked the polar regions of the planet, where I'd be just a tiny bit close to the center?

Anyway, another high-g world to scratch off my list!

After that, I just left my controls alone and went to sleep. Being just too tired, I couldn't do that one more thing I wanted to do immediately - execute some of the high-g manoeuvres [suggested by GremlinSpotter].

On the next day however, all sober and fresh, I decided to do just that and see how my Dinnerbell (Diamondback Explorer) would behave when doing some less-than-safe things on that planet. And here are the results:

Vertical thrust down (≈1 second):

• g-force at starting point: 10.97g​
• Starting altitude: 50.3km​
• Resulting altitude: 47.8km​
• Loss of altitude: 2.5km​

One full longitudinal roll:

• g-force at starting point: 10.97g​
• Starting altitude: 49.7km​
• Resulting altitude: 34.1km​
• Loss of altitude: 15.6km​

Sharp 180° turn at ≈45° ship inclination:

• g-force at starting point: 10.96g​
• Starting altitude: 60.3km​
• Resulting altitude: 31.8km​
• Loss of altitude: 28.5km​

Flight assist off (≈2 seconds):

• g-force at starting point: 10.96​
• Starting altitude: 59.8km​
• Resulting altitude: 57.5km​
• Loss of altitude: 2.3km

What does that tell us? Downwards thrust is safer than expected (at least with this ship), FA off is about as safe as I'd thought it'd be, and turns and rolls are outright deadly!

I got really nervous when I had finished my 180° turn and had noticed just how much speed my vessel had taken up in all the wrong direction: Over 450m/s downwards. Almost 30 kilometres of lost altitude speak for themselves I would say.

Don't do that on high-g worlds, unless you know precisely what it is you're doing. Especially not in a more massive vessel. It's really easy to lose ship and life by trying to have a little fun down there!

Ah right, one more thing, as I'd finally started leaving the planet, after about 20km of flying upwards bringing my ship almost onto the regular surface level of the planet, I finally saw that magic number "11" - it was here that my ship suddenly experienced 11.00g, although I'm not sure why:

I'm telling you, I so want to discover one of those supermassive landable planets myself... Guess I'll have to start surveying systems with class O+B stars.

Commanders,

Uh, it sure didn't help that I'd caught the flu during that exciting time in my explorer career, but anyway.. despite it being a bit of a burden, I managed to drag myself home in yet another single session of just blazing through system after system without even looking left or right.

After all, my high-risk (now it's "high-risk" instead of "throw-away") ship, the Yumeko was still carrying the data from HD 40064 in its databanks. I just had to bring it home as fast as possible.

That moment when I reached civilized space... Usually I don't really care much for it, but this time it was kind of special:

Home, sweet home

I even got nervous passing through the "mail slot" to enter the station, every single manoeuvre executed with great care. So that's what it feels like to bring home something truly precious!

That concludes the exciting adventure that was HD 40064. Oh, and now, after all that, let's provide you with a direct link to the system as well:

• [HD 40064]

In terms of thrill, this whole experience will surely be a hard one to beat. ;)

Commanders,

Following up on the last report, let's not delay things unnecessarily. This is what I had picked up on the galaxy map:

[Pheia Aeg WX-U d2-0]:

144.46 lightyears... "Too much", right? And in terms of fuel, this was a pointless system, too. Nothing but a white dwarf stellar remnant and an equally useless class T brown dwarf. So no way to scoop fuel there, as I'd need a class O, B, A, F, G, K or M star for that.

Anyway, why not at least look at what my throw-away ship, Yumeko-chan could possibly do:

"Well, if fuel wouldn't weigh anything..." I thought, but thanks to a helpful person called Rudi Raumkraut, I knew that the maximum range would include the fuel necessary for the jump. So at 145.73Ly my actual maximum range was higher than the distance to Pheia Aeg WX-U d2-0 - by a hair's width!

But then I thought, I'd end up there with basically zero fuel left, because I'd need to burn most of what was sitting in my tank to make Yumeko light enough for this jump. But still... I got all het up! I had to try!

First, I attempted to wreck my SRV to save mass:

But unfortunately, that didn't really work out, as it didn't reduce the ship's mass at all. The jump range before and after the scrapping of the vehicle were the same:

With that it had become clear that my only way of reducing mass would be to mindlessly burn fuel by maximizing the power draw from my 2A reactor. I managed to get it to 99% load, drawing 1.48 tons of fuel per hour from my tank. That still meant it would take over 10 hours to get to a level where a jump could be attempted.

I decided to simply go to sleep and let my ship fly aimlessly into empty space at 30km/s minimum FSD speed, burning fuel one drop at a time...

. .. ... .... ..... (this is really taking forever) ...... ..... .... ... .. .

And then I woke up to the ringing of my alarms, set just a bit early for safety. It's been 11 hours since I had started burning hyperspace juice, and now I sat at 143.00Ly of range.

More waiting

. .. ... .. .

Finally, after almost 14 hours, I reached an effective ship mass low enough to attempt a jump to Pheia Aeg WX-U d2-0.

From there, it could be either death by fuel starvation, or a call to the fuel rats for help.. which my pride would likely not allow me to make anyway, especially since this was all done intentionally. But still, there was a minuscule chance that I'd have just enough fuel to reach a scoopable star from there. With another +100% FSD injection of course.

"Clutching at straws" they call that...

In any case, after spending quite some time in HD 40064, and even growing to like the system, it was finally time to say good bye to my little big star:

Time to attempt the impossible escape! Rarely have I been this on edge!

And that would be my farthest jump without Neutron star boosting, and by a long shot at that!

(This screenshot features blocky artifacts, my apologies for that)

Still quivering a bit, I immediately injected my frame shift drive with another expensive +100% charge. Arsenic be damned, this was no time to save precious resources! A quick glance revealed that the system was indeed without any scoopable stars and also without any planets. Just that white dwarf and a brown dwarf. What a desolate place.

My pulse was at a record high now. There were two potential life-saving stars I had picked for my escape, further down below. I attempted to reach the class A blue-white star in [Pheia Aeg XX-U d2-0] which I thought was closer than the second candidate, a class F white star.

And so came the moment of truth.

Would I be able to reach it? Where the moment when I hit that hyperspace switch to enter HD 40064 was a bit unsettling... now it was just plain nerve-wrecking!

To think I had originally come here to die here.

Well, time for the final gamble:

Heeeh... eheeehehehheheHEHEHEHEELL YEAH!!

Oh.. my.. god. Unbelievable!!!

Aahahaaaa! I made it!!

Oh Be A Fine Girl, Kiss Me!

This felt indescribably good! I honestly laughed out loud when I saw and heard the hyperdrive revving up to carry me and my ship to salvation! And then the moment when my 4A fuel scoop started thirstily filling my almost empty tanks from the hydrogen in that star's corona...

An uplifting feeling!

Now, from here, all I needed was a reachable Neutron star a bit further down. I quickly noticed that none were in regular FSD range, but another +25% injection indeed brought one of them into reach. That was the system [Pheia Aeg VM-W d1-0]:

Hellooo, Mr. Neutron Star! I am ∗very∗ happy to see you!

From there I was set! One more Neutron star - now easy to reach - and from there a boosted 265Ly jump down to actual safety!

After that, it took me a few seconds... But then I just sunk into the back rest of my pilot seat, letting the air slowly escape my lungs with pure relief. I had to chuckle to myself a little, thinking that I had thought nothing of self-destruction in HD 40064 when I had left the station in civilized space. And in the end, I went to such lengths to get my arse out of that place... and that sure as hell wasn't good for my heart either. ;)

But I don't mind the feeling I have to admit. What an amazing thrill!!

Seems Yumeko won yet another high-stakes gamble after all!

Unbelievable...

Commanders,

In this fourth report about HD 40064 I will take a closer look at the planets in the system.

The most interesting seemed to be the second gas giant, with its reddish colour, so I decided to visit that one first:

There's really quite a bit of light coming from the class K0 I supergiant, so there was no image post-processing necessary; The giant planet really looks bright red! Nice.

For my moment of Zen I decided to land on one of its metal-rich moons and gaze upon the large planet and the gigantic ball of fire behind it:

What a view to enjoy, especially when knowing that there is absolutely nothing around that system for many dozens of lightyears...

The next candidate for inspection was the first gas giant in the system, which seemed a bit more boring, or a bit more beige, but larger:

That protuberance over there... I wonder how high up it actually goes, and how much mass the star's ejecting there?

Number three to inspect was the large, ringed high metal content world on the outskirts of the system. I just couldn't hold back and had to play around with its rings for a bit. ;) See here:

Gorgeous! Just wonderful, how the light shines through that ring. When you have nowhere to go anymore, you start to enjoy the little things I guess. ;)

The final body I chose to visit was a small rocky moon orbiting that high metal content world, as it appeared to have some impressive mountain ranges. Surely not he highest in the galaxy, but pretty impressive nonetheless:

Now, as for the final part.

While it was never planned, I could at least look around, right? For a potential way out. When Yumeko makes a high bet, she ain't just gonna fold right away after all.

So I tried and tried on the galaxy map, but nothing seemed even remotely close enough to make a jump there. That was until I found one small, blueish blip I had overlooked before... at quite a staggering distance still.

And it didn't look very inviting either.

What that blip was, and if there is an actual possibility to get out of HD 40064 alive, you will read about that in the next and final report about the red supergiant system.

Commanders,

The time had come. The enigmatic boom of the hyperspace exit, and I had entered the system I had so far only managed to gaze upon from afar:

One of my greater fears was that I would find only the star with no other bodies around. I felt my one-way trip would've been just a bit of a waste in such a case. But fortunately, that was not the case at all! The red supergiant system featured a lot of planets to explore!

That made me quite happy and relieved, actually. So I fired up my full spectrum system scanner, and identified all bodies present in HD 40064:

Alright, we got two class IV gas giants, one large, ringed high metal content world, and a plethora of metal-rich bodies plus a few rocky moons. Not too shabby. Of course, I got no free Neutron star thrown in to get back out of there, but heh... of course not...

I'll explore the system in greater detail in my next report!

Commanders,

Getting back to the base system for my attempt to reach HD 40064 went a bit quicker than my return from there to the bubble, courtesy of a certain frame shift drive booster and reduced ship mass.

I started from the neutron star known as [HIP 25704]:

From here, there was only one way: Up, up, up!

Next stops were all Neutron stars, [Myeadai YE-X d2-0], [Pheia Aeg TM-W d1-0] & [Pheia Aeg ZD-T d3-0].

What a nice feeling to get over 270Ly of range with Neutrons... I could've actually stopped at the second Neutron, which was the stepping stone I had originally picked for reaching HD 40064 in my first manual plotting attempt. That was before returning to the bubble for building a dedicated ship for this mission. The distance from there to HD 40064 was 225Ly, so the Dinnerbell with her 228Ly boosted range could've actually made the jump. But I found one Neutron just a bit closer than even that, and that was Pheia Aeg ZD-T d3-0.

Myeadai YE-X d2-0:

Pheia Aeg TM-W d1-0:

Pheia Aeg ZD-T d3-0:

With this, HD 40064 had finally came within my reach. But there I was - hesitating. I was aware of my coming here with suicidal intent of course, I knew this was going to be a one way trip to hell... but when it comes to actually flipping the switch... I still got cold feet for a bit I must admit.

But turning back was simply not an option at this point. I took a deep breath, a few seconds of silence, and then I flipped that switch... "jumping fearlessly into the icy void of space", as a certain narrator once said it.

Feels... elating, somehow:

As to what I found there, you will read about that in my next report!
