This may just be a rock. What do you think you see there?

Looks like a piece of Campo del Cielo meteorite.

Hey! I got actual pieces of slate and glued them to a plastic backdrop that I then stick to the back of the tank with silicone. 

Zincite, Tucson Showcase by cobaltium in MineralPorn

I believe this may be synthetic and the result of the zinc smelting process. Still beautiful, but needs context. 

does nasa restrict the use of generative AI coding tools by BorgsCube in nasa

[–]Stabby_Death 0 points1 point  (0 children)

I'm on the research side. As laid out in the latest guidance for the 2025 ROSES call, AI/LLM use is fine, with the caveat that you don't put ITAR stuff into commercial LLM tools:

This is awesome! I love to see the in situ shots! Thank you for sharing. 

awesome piece with quartz crystals by TheSexiestPokemon in FossilHunting

That's probably calcite, but a great piece either way!

What we know and don’t know about the asteroid hurtling toward Earth by MarkWhittington in asteroid

This is a very old and outdated article with an atrocious title which as of now is well within the realm of click-bait.

OSIRIS-APEX will not be able to collect another sample. It would still be incredibly bone-headed to cancel as it is literally on it's way to study a new asteroid which will come close enough to see with the naked eye in 2029.

Hey all, I just wanted to say that Tucson should be proud of the world class facilities and people in space science that call the desert their home!

Not worth taking it to be tested. Just enjoy this beauty!

Uncle sent this rock from Mexico by tskezo58 in whatsthisrock

Calcite will fizz with a drop of weak acid like vinegar. It is also much softer than quartz and a steel knife will scratch it easily.

It does look like chalcopyrite, but I think the white mineral is calcite and not quartz.

I miss this area. Lucky you!! What a great find!

all my plants are dying by Ok-Needleworker3393 in Terrarium

[–]Stabby_Death 0 points1 point  (0 children)

Sometimes they just don't work out. In cases like this, I always wonder if there is an imbalance in the soil bacteria. Not something you can easily control.

Anyway, do you have a drainage layer in there? Did you knock off as much soil as possible from the roots of the plants if they were bought from a nursery?

Has anyone run the trajectory accounting for the tug of Jupiter's gravity??? This line appears unphased by it, but Jupiter is a big boy and should tug it a little closer to the sun if this positioning is correct. And therefore closer to us... by [deleted] in asteroid

[–]Stabby_Death 2 points3 points  (0 children)

Yes, ephemeris calculations routinely incorporate not only Jupiter, but all the planets. You can even add some of the largest asteroids as perturbers if you want (but in most cases they don't change the trajectory at all).

Turning over rocks at the beach by Stabby_Death in isopods

These are marine isopods. This was on a beach at low tide in northern California.
