I started having space fatigue around this time last year. I also wanted wanted to explore some other (digital) realms the last couple of months.

Not being able to download my data source any longer (since the entire EDSM bodies-dump hasn't been available for quite a while) didn't help with getting back into the cockpit.
Please don't misunderstand me. I am certainly not blaming the fantastic EDSM regarding the decision not to publish it any longer. I can emphasize with the decision and merely wanted to say that I was a bit in stupid situation here.

Anyway, at one point Eahlstan was very helpful with a pointer into the right direction:

Behold the mighty dumpverse of https://edgalaxydata.space/

When that was first posted I was excited … but soon afterwards a bit disappointed since it still wasn't the entire dump.

Well, long story short. The void was calling since a while now. And today I was looking at said source a bit more closely and had almost at once an idea how to get my data up to date once more. Thanks again for this very helpful hint.

Thus, I hope that my journey will continue soon-ish … depends all on how fast i am implementing said idea.

 

[Shir]

This must be one of the most inspiring and fun threads i've read so far! Greatly enjoyable!

 

[Eahlstan]

Well, if you don't want to fuse Bravadas dumps you can still get a full galaxy dump from Spansh https://spansh.co.uk/dumps

 

[schlowi123]

@Shir: Thank you for the compliment.

@Eahlstan: if I remember correctly did I check the spansh dump and discovered that my program didn't work with it. The latter is very much "locked in" with the EDSM data and I've spend many hours to put rules up what (and when) to ignore if it is not correct (some of that process is documented here).
But I'm always very happy for hints and pointers since there is a vast amount of information I don't have . So thank you for that.

 

[Eahlstan]

Since you're looking for records you might also be interested in Orvidius' records page: https://edastro.com/records/
That one should make your local record searching almost completely obsolete.

 

[schlowi123]

Oh yes, i have seen that months and might implement something that takes all of these records out of my journey … which might indeed leave me with just a few remainders.

 

[schlowi123]

The disadvantage of still not having learned how to database means that i have to stitch together the EDSM data month for month. That is a rather slow process since I have to check for updates to already existing celestial bodies. Also: the dataset is growing by almost 10 GB each month.

Anyway, after checking how far I came in my journey I realized that I had not yet reported two of the records that i had visited.

The first one is the Gas giant with water-based life that holds with 2 ls the record for the shortest distance to arrival. Its name: Dryu Auf AA-A h30 A 1. Its face:

It's trying everything to not fall into the infinitely deep gravity well of the black hole it is orbiting and thus has a velocity in periapsis of 7,423,463.957453908 m/s or approx. 26.7 Gm/h. That is the highest value of this characteristic for all the celestial bodies of this types.

 

[schlowi123]

And the second missing entry from half a year ago (or so) is Dryio Flyuae XF-N d7-2082 ABC 1:

It didn't make much of a difference to land on the day- or nightside if the planet since this is the landable (!) High metal content world with the largest semi major axis (26,570,215,266,904.36 m or ca. 177.61 au) and the orbital cirumference 166,878,791,233,191.34 m). Unlike many other times does the record for the longest orbital period NOT follow automatically from these two. I think I had discussed that somewhere earlier in this thread.

Now I'm waiting for the data to be fresh again. I don't think that'll be done before I'm going on vacation in three days.
Anyway, I'm just happy that i didn't need to start from scratch but still had the EDSM bodies file from march last year.

 

[schlowi123]

… … … This journey might continue … … …

 

[schlowi123]

Uff … that took a while. I could blame The Shoulder of Orion event but that would be kind of dishonest because I happily participated in that, not the least because I could procrastinate on this task without a guiltyu conscious. The reason I was procrastinating: the data has is now so big that I can't just uncompress it any longer and work with the uncompressed file but had to find a way how to unzip one line at a time.

In addition was there some other kind of data that I've been holding completely in memory when I did this excercise the last time (which was … checking … oh darn! In March 2020) and which also can't be in my RAM any longer completely (at least not if I want to do sth. else with the Laptop). So I needed a way to find around that and since none of my clever ideas had the desired effect, I sighed and decided in the end to turn to the "brute force" method (which in this case means simply processing said data twice under different conditions and keeping just the actually interesting (small) bit (pun intended) after the first run) … also: gosh! never look at code that's a couple of years old … I shortly contemplated to simply start from scratch.

Anyway … I may head out into the black soon-ish … but maybe not because sth. in IRL is coming up.

 

[schlowi123]

I shortly contemplated to simply start from scratch.

Of course I couldn't let that go for real … I never seem to be able to do so.

So, I'm in the process to rewriting my code with respect to the new data source and past experience. Well, it's not an entirely fresh start from scratch, since I don't have to think through all of the algorithms and functions but just need to "adjust" them.

Said code is now MUCH improved (structurally … hooray to the power of objects!) and thanks to the different structure and information included in the spansh data (compared the the old (!) EDSM data) it's also A LOT less memory hungry … it might be an order of magnitude of a difference (yes, my old code wasn't very efficient).
In addition is the processtime reduced by at least a factor of two. Down to approx. seven hours in total (compared to well over half a day before).

Not finished so far because a lot of additional tools in connection with this will get a rewrite to.

 

[schlowi123]

Finally! Everything works (again). And the code is so much more readable now … and timewise SOOOOO much more efficient, compared to what I had before.
Of course am I swamped IRL for the time being and will be away from the ship in 3 weeks (for almost 5 weeks) … I'll try to get going before that because I'm giddy … but I won't promise anything.

 

[schlowi123]

(A) New data(source), an improved algorithm … All right! Here we go again

I have not yet decided about the overall "theme" of this tour … or well, I did and that turned out to be an error because I had forgotten to exclude certain, elsewhere registered records; thus, I have to think about that again. So for today I present four (seemingly) random records … of which one is not a record in the usual sense … and it's also not unique … anyway.

It starts unspectacular (like almost all of the records) with Pencil Sector HR-W d1-160 A …

… the L (Brown dwarf) Star with the highest orbital period of 2556083738803.8613 seconds … which are more than 81-thousand years

The next one is the ELW with the highest rotational period of 67905.2265593311 days:

It is Synuefe PC-K c25-3 1 … and I do NOT think that this would work because the one day of this ELW lasts for approx. 272 of its own years. Thus, day and night is determined by the movement around its star … I would expect the water to evaporate on the dayside and to freeze on the nightside like it does on Earth at the poles … on the other hand, maybe if they have a greenhouse effect that is just about right to keep it liquid … checking … nope … the average surface temperature is even lower than on Earth.
Mhmmmm … maybe the ocean currents are really strong and manage to transport loads of heat to the dark side … yeah … that might actually work. Someone should investigate this.

I on the other hand decided to move on to Swoilz BM-Y c3-25 AB 5 …

… which is above mentioned NOT-a-record. But of all values for all planetary and star characteristics comes the value of the surface pressure of this beauty with 2.71828182827535 atm closest to the value of Euler's number. The discrepancy is a mere 0.00000000018369528120842915 atm.

There is just one other value in the whole galaxy that comes (exactly) equally close (and it is also the surface pressure). But for that one needs to visit Thus, the above is not unique, but I wanted to include it anyway. But for that one needs to visit Chao Eurl FF-A c1 2. So this is neither a record, nor unique, but I wanted to include it anyway. However, I will not fly to Chao Eurl FF-A c1 2 … one of them is enough.

The next one is HD 119338 …

… as one can easily see, the system with the most brown dwarfs.

And the last for today is Phylucs RK-Z c7 2:

Of all so far found planets is this the one with the highest axial tilt. It has a value of 89.99998127603168 degrees and due to the rings it was quite nice flying towards it .

Until next time

 

[schlowi123]

It is decided.

After the success of operations "WHITE DWARF", "YELLOW ORB" and "GOODBYE, BLUE MONDAY!" follows now Operation "MOSTLY HARMLESS".
Albeit just ELW's would be a little … well, little. So all record holding rocks in space are included.

The fuchsia coloured dots in this map …

… are the objectives and the blue line marks a mostly optimized route between them. I will fly counterclockwise.

It is shorter to mention what will (in general) NOT be visited during this tour: (not just gas) giants and stars. With three exceptions.
1.: The yellow dots are record holders that I want to get out of the way and that are somewhat "on the road".
2.: The red dots are also dots that I want to get out of the way but I haven't decided yet if I'd rather make a dedicated (other) operation out of that. I'll decide that on a whim.
3.: Not marked are the myriad of record holders that are around the core and on the Colonia-Sol highway. If there are any "close to the road" I'll probably visit them.

So … onwards! To boldy go where someone has gone before.

 

[schlowi123]

I've been flying for a while already. But the first record holder was this Water world, Flyua Dryoae UP-J c24-3 A 10:

of all of them has it the highest axial tilt with 89.99990413240933 degress. Unlike the entry above was that neither very visible while flying towards it, nor when bein up close.

 

[schlowi123]

The 2nd entry for today is not a record at all. But of all celestial bodies in the archives is Swoidai IX-J d9-0 10 just one of two, that has a characteristic with a value that comes as close to the fine structure constant as 1.1937030031106133e-08

Said characteristic is the surface pressre with a calue of 7.29735257833703 atm.

This time I unfortunately can't tell you the other one, because I've deleted it already from my notes … and am too lazy right now too look it up in the results the algorithm spits out.

 

[schlowi123]

Alright, the next stop was Syralaei LQ-G c10-24 B 2 …

… the high metal content world which has with 322369.957238215 days the longest rotational period of all of them. In addition is it landable (so that's a double record) and I think the image above is my first picture on this journey in which I'm standing on a surface.

To my dismay did I not get First Footfall … Dam you YRMWULF!

 

[schlowi123]

Prooe Hype TT-R d4-0 A …

… should have been part of "Operation Yellow Orb" (back in the days) … however, apparently it wasn't discovered at that time and the dimmest CJ star record must not have been unique and thus wasn't registered. Now it is and the value of the absolute magnitude of this record holder is 0.843842.

 

[schlowi123]

Yet another sidestep from "Operation MOSTLY HARMLESS" is HD 114792 A:

In the category of F (White super giant) Stars is this the dimmest one with an absolute magnitude of -7.159393 … which is quite a lot more compared to the one just above.
