@TildalWave That looks amazing, thanks. for now i'm going to have to just have it play in the background and absorb what i can. i'm sure it will affect my design a lot, but i still think i am very likely to stick with a couple of concepts i have barely seen explored, principally direct melting of the regolith to make structural components such as planks, beams, columns and tiles, and excavation assisted by melting.

i have seen it explored a bit, and also basalt fiber, but not much.

They talk about it in a lot wider sense than the title of the workshop might suggest, lots of it applies to what you're designing

"they talks" LOL

yeah, i already looked quickly through the slides of a couple of presentations

it truly is packed, and if i stopped right now to give it the attention it deserves, i'd do nothing else for a week, i suspect :P

neah, it's only what, 4 or 5 presentations of about 45 minutes

and i will duly do that after the space show interview

I literally swallowed them in one go

sure, but you have a lot of background, and also you aren't mulling how that affects the design of an entire base you have already come up with as you watch

i'll likely listen to each three times and take notes

that's true

I never take notes, that's why I never remember where I heard something, only that I did

OK I sometimes pretend to take notes, especially during business meetings :)

@TildalWave plausible deniability built right in

exactly

funny it would come up two times in two different rooms I'm in in such a short notice LOL

now that i've mastered more of blender i redid the landscape

@TildalWave it's an omen, man :D

@kimholder geez that's in blender? That's fantastic I thought it's some crop of some photo at first

no, turns out there is a way to shape right on a photo

it's even simple, just uses a tool i'd ignored before because it's finicky

i have to check the height of the boulders, they are probably a bit off, but not a lot

I know, but I didn't expect it to also map the background so well once in 3d

i imported a quickmap set of LRO photos (had to mix 3), and started cutting it up into areas that i then stretch out vertically to match their approximate elevations

but why does it look so flat?

I have blender installed, but have no idea how to use it. I just use it to look at the Moonwards models

is that because of scaling?

that Apollo photo shows it as really steep and LOLA data also suggests it should be inclined quite steep

what i stretch is all done by hand. if i haven't adjusted it, it's flat

the interior of the crater is pretty close to 37 degrees already. may look like less because of the angle.

have to refine everything, but its decent for a first pass

could you somehow use that Apollo photo as an additional background and adjust stretching like so?

it seems to me as if the y axis is flattened

i'm using two LRO photos principally. The area i'm working on is very small in the apollo photo

I know, but LRO photos basically only give you x and z

@kimholder Is your landscape model of the Lalande region available for download?

@kimholder hmmm here it looks better already

@Hohmannfan i can post the model Brian Lynch made, but i need to work on it some. it is a great help but has artifacts from the instrument, and right now is a huge file too.

also learning blender at home is quite doable if you can put in the time. SE has a site for it, there are lots of videos on youtube, lots of free tutorials, and once you are in a little deeper, a few worth paying a little for.

@TildalWave i just turned it a little to be more horizontal to the camera

yeah I get it, it's about perspective

unfortunately there are only 2 LRO photos where the area is lit

and like 7 more where it is in deep shadow and nothing is visible

that Apollo photo wouldn't help to fill the gaps in a bit?

a bit, i have been using it a little

especially for the angle of the downslope going away from the crater rim

i do believe i'm going to have it printed up on a plastic canvas about 6 feet wide :]

i can get that done for like $10

that isn't quite full resolution of the area, but it's close

I see there is sort of a step halfway down the crater wall. Maybe a good place to anchor the bottom of the PESS?

you mean that shelf i refer to sometimes? yeah, that was my idea. though i'm pretty much a convert to thermal energy storage now

thanks a lot for doing the numbers on that by the way

(of course, if i could blast off a big chunk of the crater wall maybe i'd change my mind. but that's probably a bad idea :}})

perhaps you can have both the systems? the Multiple Energy Storage Systems (the MESS :D).

@Hohmannfan LOL... i am going to use that

@Hohmannfan oh, if i can help with editing for grammar, no problem.

of course, i know from how i struggle in spanish sometimes that figuring out how to say something technical in a foreign language can be a real challenge.

@Hohmannfan PESS?

I presume TESS isn't Transiting Exoplanet Survey Satellite?

Potential energy storage system

Thermal energy storage system

ah gotcha

i do like my acronyms. MIP - melt in place. i talk about MIP beds and MIP hardware

PESS should totally be named Sisyphus :)

oh it should, ha!

it would be even better if i could fit that to a descriptive acronym

shortening it to sisyfus might help.

but you need the p for potential

true...

and there is no e for energy

I feel like NASA now, trying to invent an acronym after having a proper name for it

oh, but ESA beats them at that game.

I think it's a tie

Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer = OSIRIS-Rex

I kind of like "Aerodynamically Integrated Retrograde Braking Robustly Armed Kinetic Extending System" (A.I.R.B.R.A.K.E.S.)

(from KSP)

hehehehe

i should go make dinner, then we're watching Bridge of Spies

i think i'm probably not going to be here much next week, similar to this week

My fav bunch of acronyms are WIMP = Weakly interacting massive particles, MACHO = Massive astrophysical compact halo object and RAMBO = Robust associations of massive baryonic objects

Norwegian University of Technology and Science

(⊙_◎)

ciao for now guys

c1a0

about acronyms :)

or 49568 in decimal

Gravitational waves may have been detected.

@PearsonArtPhoto Damn you Einstein! You should have proven your work,not waited 100 years or more to prove it.

Too bad he's dead, his Nobel Prize could have been awarded after his theory was proved;-)

@PearsonArtPhoto When science needs 100 years to build the technology to prove your theory, shows you did a good job thinking about it. :)

I suppose that's true.

Is not "Gravitational waves detected" what pops up in the news twice a month?

apparently the announcement is gonna be webcast live spaceref.com/news/viewpr.html?pid=47855, but I can't find where, this is all there is press.org/events/national-science-foundation-press-conference

@PearsonArtPhoto You around?

could you make a plot like that?

Perhaps...

Maybe in a few hours. I don't have STK easy access like I have in the past, but I could download it still...

cool, I won't be able to do it till late tomorrow

I know I had a plot of it already...

yeah that solar beta angle is nearly there
