Prospecting study completed 65,000 Ly from Sol

On the Distribution of Materials According to the Topology of Planets


Press release:

A new study finds that the best place to go looking for elements is on flat lands. Logging the location of nearly 500 mesosiderites, the science vessel Aspera and her crew
were able to find a statistically significant increase in density for this terrain type compared to craters and valleys. The study, published earlier this week in the prestigious
journal Planetary Review Letters, was done around 65000 light years from Sol
as part of the Distant World expedition to make sure that human terraforming attempts and pollution would not interfere with the results.
"We are all very excited to finally tell the world about our work. Big hats off to the science team for their outstanding efforts. Now we look forward to a quick stop at Jaques
when he arrives to fill up on supplies and celebrate the findings before commencing the trip home." said John Rutherford, commander of the Aspera.

TL;DR

In this paper we present the results of surveys that focus on identifying the rate and locations
at which mesosiderites can be found. The surveys were done in association with the Distant Worlds
expedition and were all done on a single planet, christened “Skrinir”, close to Beagle Point. It is found
that a planitia type terrain (flat lands) give a statistically significantly higher density of mesosiderites in
comparison with a crater and vallis terrain region. A pattern of higher and lower density is indicated in
the crater region, with higher density towards the central peak and circumference. The pattern indicates
that findings of mesosiderites is more dependent on location than on time. In the introduction we also
review some relevant facts about prospecting that are already known to the prospecting community but
might not be well known elsewhere.

We found after doing many surveys that on average, the density of mesosiderites were given by
σ[SUB]1[/SUB] = (6 ± 2)(10km)−2 ,
σ[SUB]2[/SUB] = (11 ± 2)(10km)−2 ,
σ[SUB]3[/SUB] = (7 ± 1)(10km)−2 ,
for a valley, a flatland and a crater respectively. Extrapolating these results to hold generally we therefore
advise prospectors to go to flatlands and collect metallic meteorites to get high rarity materials as fast as possible.

As we can see in the figures below, the mesosiderites are fairly uniformely distributed in the flatlands,
while we see a pattern in the crater with more mesosiderites towards the central peak and the circumference.
We also found the distribution to be fairly uniform in the valley.

Should that be 65000 nor 6500?

Irrespective of distance, great job that validates my totally unscientific view that flatlands are best place to find mats...

Thanks Cmdr

Oh, darn, I got the title wrong of all things. Been revising the paper all day so my brain is mush! Thanks for notifying though.
 
Excellent work!

A few questions
- what class of planet was Skrinir?
We found after doing many surveys that on average, the density of mesosiderites were given by [...] advise prospectors to go to flatlands and collect metallic meteorites to get high rarity materials as fast as possible.
- are the patterns of mesosiderites and metallics the same, or do these results only apply to mesos? (Anecdotally, I find metallics appearing far more in mountainous regions than flatlands, on rocky worlds, which wouldn't match this but could easily be small sample size)
- how did you attempt to control for the greater ease of moving around a flatland? Is it possible that the result is caused by the way meteorites are added by the engine rather than intrinsic differences between locations? (Particularly an issue if the survey pattern involved backtracking, and not actually relevant if obtaining minerals is the goal)

Skirnir is a HMC type planet. I chose this type, since it is one of the more popular prospecting types as well as not being very rare. I needed it to not be rare, since I also wanted it to be located in a system with a single star, not have any satellites and not be tidally locked to the star, all of which are factors that could theoretically affect the distribution.

As far as I know there is no existing evidence of whether it is the same or not, since AFAIK this is the first type of study of its kind. The assumption is that the distributions would be similar, but this is certainly a point that warrents further research.

Not completely sure if I understood your last question, but there was very little backtracking as all the surveys were done in more or less a straight line. For both the crater and flat-land all detected signals were investigated, so ease of travel would only affect the time between mesosiderites and not the location. If the geographic location is speed dependent on the other hand we would expect to see a decrease in density when moving fast to be consistent with the pattern for the crater.

Yeah, I could edit the title of the thread but not the title of the thread as a whole. Thanks for telling me about the possibility of reporting it!

I have a done a diff study, and it was about the srv speed. The amount of crops/meso/meteos per km2 is inversely proportional to the speed of the srv.

I mean, being the appearance random, it has the same phenomenon as POIs in space: if you are traveling fast, pois appear several Ly from your position, while if traveling at minimun speed, they appear at 300km.

I went to check this on planets and while traveling at speeds below 6m/s, you get all crops/meteos/mesos in a radius of 2km2, no need to travel any further. Sometimes they spawn right behind the srv as well, so after advancing 300m, if you turn around you can see the signals right where you just passed with the srv seconds ago.

I assume my tests do not invalidate the distribution results of your paper, but the % per km2 might be affected by the speed, just saying in case you want to check in future prospections. Perhaps you already considered that, if that is the case sorry for the noise :)

No need to apologise, we actually wrote this kind of study as possible further research in the outlook section. In the topological pattern section we also hypothesize that the spatial density is inversely proportional to the SRV speed, but conclude with negativity, based on the shape of the pattern found in the crater terrain region. However we do not consider this conclusion as very firm since the shape of the pattern as not very quantitative and could be interpreted in different ways so I will not be surprised if this is actually the case despite what we concluded (or that this does factor into the equation in some way at least). This wouldn't invalidate the main result however, seeing as this effect would be averaged over by going equally up and down in the crater and would effectively mean that the gap between the density on the planitia and vallis terrain is larger than what we measured since we were going faster over the planitia
(faster => lower density, but we found that density_planitia > density_vallis).

Nice work.
Even if the distribution was equal, it is much better to prospect on flat terrain, so much quicker and easier to get from one source to the next.

Well, in my tests, I was travelling at very low speeds until the signal was clearly defined and audible, then it is when you can throttle up to max speed to reach it faster, as it has already been located and assigned coordinates. Any attempt to run while he signal is still dirty will make it appear far from the current location. I verified in different planets and also asked a friend to do the same type of tests. Not that we were trying to be scientifically methodic, but trying to speed up the materials gathering process.

I do also had pending another test. Due to the amount of crops/meso/meteos in relative close location, and because I was looking for specific materials, I was just abandoning quite a lot mats here and there. After some time I starting noticing what it seems to be a kind of a "cap" in the materials listed in the contacts tab, as I could select the target in front of me being a very rare item that was not present in the list. I just noted to work out these numbers and it is still in the queue of things to do.
