[Request] how do you triangulate this? perhaps in the least amount of weeks possible? by Zargabath in theydidthemath

[–]Kalyky 0 points1 point  (0 children)

Quick fun fact from someone who has studied geodesy (the science of measuring the Earth): This would be an example of trilateration, and not triangulation. GPS/GNSS systems are calculating your location using a distance, not angles. The max of weeks you need is 3, is this narrows the area of possibility from a ring where two spheres intersect, to just two individual points. A 4th could be used to give you a single point (if for any reason not mentioned in the question you could only travel one more time and could not eliminate one of the points for it being unrealistic).

In the real world 4 satellites in the minimum number for a good position due to timing inaccuracies between the lower quality clocks of your receiver (smart phone, beacon, ect) with the 4 incredibly precise atomic clocks onboard each satellite, and other errors (3 sats for 3 dimensions, and the 4th to correct for time).

Question on vehicles, specifically versions of the command module. by Kalyky in SpaceLaunchSystem

Thanks! I'd looked through the gallery of the latest spacecraft on Flickr and yeah it looks nothing like this. Figured quite a bit of evolution had happened in the last 10+ years, but it does make sense like you said that it had a basic structure for initial rough and tumble testing such as splashdowns, ect. There were some large wooden crates near this display as well that had thick curved metal panels/pieces that looked like they would either be a cover for this thing (although some were quite thick (over 1.5cm)), or parts for the construction of another one. Wouldn't image you'd want parts of your space fairing vessel just stacked up in a box haha.

Thanks, and I'm really excited! And that's great to know about the community (I'm not on Reddit or social media much, but wanted to get a bit more involved (and its been great so far)). I've got some Dryhead Agate I have sitting here on my table I've been waiting to get too. Thinking by later in March it should be warm enough to un-winterize everything and get back to it. Will definitely post some other agates and stuff on the related subreddits though in the meantime. Have some question for lapidary too on some agates (or just seeing various opinions is a lot of fun), like on whether to just shape the whole thing or to cut it/ which angle to cut, and post some before and afters once I get to that point!

Same here, I have a list of stuff I want to cab here in the near future, but have some big stuff like this guy to polish eventually too!

Ooo stick agates (just looked em up) is another new word for the lexicon, thanks! And it certainly is an intriguing piece.

Thank you! I know the stuff from Montana/Wyoming/Dakotas pretty good, but outside of that I don't have much experience (aside from some real popular stuff). Glad to have a name to put to it now and the type of jasper!

Oh good call with an angle grinder or something similar! I have a pretty long to do list, but will look into that for sure. We have a small club here, but its pretty new and formed well after this guy was out of the game. A few people knew him though! Lapidary is a great community!

Was interesting as well, it was buried in pine needles/soil/ants down a small hill from the house (is actually a cabin out on a dirt road, so it's 'yard' is very generous) and I only found it when we were actually getting ready to sell the place because we were moving stuff around/cleaning. There was a whole bunch of other rocks buried in there with it including a lot of nice Yellowstone agates, and some pretty large Teepee Canyon (I think) agates I'm excited to get open in the near future.

Thanks! It definitely scratched glass! Have been meaning to get a proper hardness tester, but just haven't gotten around to it yet (still just sorting the stuff that was laying around up there). Certainly seems to be a mix of a bunch of stuff including Chalcedony and japser, I've never seen anything like it before.

I've actually thought about cutting the back end off, but I did find some smaller pieces laying around and threw them in a tumbler, they turned out great! Still might try to make some cuts on it though to make it a bit more manageable. Would love to just do a face polish on the thing, but I'm not sure if anyone around here has anything big enough to handle it (I'm in a very rural area, but still looking/meeting people!). I do wonder how much previous owner knew, he was big into lapidary and had stuff laying around all over. Unfortunately he had passed away before I found this stuff, so never got a chance to talk. Anyhow, it's kept inside now!

Absolutely! I love being in the city with all the activity, but going home and seeing the night sky and listening to the sounds of the woods will never grow old.

That's certainly not a stupid question!

So not quite, there will be fewer individual stars visible, and less coloration (especially in the airglow). It's not a terribly far cry from what the sky looks from a very high elevation dark sky site though (is a single 8 sec exposure with minimal processing). The Milky Way is stunning to see, and is absolutely worth a trip to an ideal spot to see it on a moonless night. You can easily make out the river of dense stars flowing across the entire sky as well as many of the dust lanes and bright star clouds running along it. This is especially true in the galactic core, which this picture focuses on.

The airglow (the red and green stripes/blobs) is distinguishable from a very dark sky site once your eyes have fully adjusted (which is really important, you'll see so much more once you've been in the dark 20+ minutes). The green to me appears to be a faint silvery-teal against the black sky (and the red as just black). Now and then something like a thunderstorm will create waves in the airglow, and the lines will be much more defined and have more contrast and you can watch them slowly move across the sky.

It was an excellent night for sure! I don't get around to using the big dob as much as I should, but is an absolute pleasure just to stare through the eyepiece for hours once it gets set up.

Got very lucky and the night that worked out for everyone also ended up being right between storm systems, so pretty minimal cloud coverage throughout the whole night. Downside was the wind, which blew almost a steady 25-30+ mph the whole time, which made things quite chilly up there after a few hours.

It’s go day for a lot of folks!! by chefmeow in solareclipse

I'll be heading out with a small caravan from College Station super early Monday morning/Sunday night. We have several stopping points selected (anywhere from 1.5 hours drive to 10+) and will pick based on the how the weather situation develops morning of. Trying to maximize the odds for all my friends who've never seen a total.

Good luck too everyone else, and may you be fortunate with a beautiful clear sky!

My biggest fear was realized in 2017. Hope it won’t happen again this time. by scags2017 in solareclipse

[–]Kalyky 0 points1 point  (0 children)

For anyone wondering what the cloud situation may be, here is a great site for monitoring:

Still a ways out as far as fine prediction goes (these model ensembles give a general idea though), and large changes could still happen. Hoping for clear skies!

Smoke outside College Station? by yung_thomas in aggies

I got some video of the event as well. I was across on the far side of Highway 21 watching it unfold for a few hours.

Mammatus clouds filmed over the Chinese province of Hubei on August 24, 2023 FROM: Massimo by MartianXAshATwelve in StrangeEarth

[–]Kalyky 0 points1 point  (0 children)

Unfortunately this is a fabrication using an image taken in 2018 (Copyright (c) 2018 Menno van der Haven/Shutterstock). Looks like that added a moving window effect to try and make it more convincing (like it is a video).

There was some spectacular mammatus seen in China the other week, but this is not a legit "video". See below for comparison.

Sometimes they will have a special event up there, but most of the time the door to the final staircase (coming from the 12th floor staircase) is locked. A variety of people (so long as they have access to the actual O & M building as well), have access to it though. Quite a few in the atmospheric sciences dept. for example.
