Anyway have this funny Nintendo snippet

Don’t fuck with moon dust. No seriously, do not fuck with moon dust.

Absent any moisture or atmosphere, millennia of asteroid impacts have turned lunar regolith (soil) into a fine powder of razor sharp, glass-like particles. What’s more, the solar wind imparts an electric charge on the dust, causing it to cling to any and every surface it touches through static electricity. On earth, sand tends to get smoother over time as wind and water tumble the grains about, eroding their sharpness. Not so on the moon – lunar dust is sharp and deadly. This is Not A Good Time if you’re an explorer looking to visit our celestial neighbor.

During Apollo, the astronauts faced a plethora of unexpected issues caused by dust. It clung to spacesuits and darkened them enough that exposure to sunlight overheated the life support systems. Dust got in suit joints and on suit visors, damaging them. It ate away layers of boot lining. It covered cameras. Upon returning to the cabin, astronauts attempting to brush it off damaged their suit fabric and sent the dust airborne, where it remained suspended in the air due to low gravity.

Inhaling moon dust causes mucus membranes to swell; every Apollo astronaut who stepped foot on the moon reported symptoms of “Lunar Hay Fever.” Sneezing, congestion, and a “smell of burnt gunpowder” took days to subside. Later Apollo missions even sent a special dust brush with the team to help clean each other and equipment. We don’t know exactly how dangerous the stuff is, but lunar regolith simulants suggest it might destroy lung and brain cells with long-term exposure. 1

In fact the dust is so nasty that it destroyed the vacuum seals of sample return containers. We no longer have any accurate samples of lunar dust, “Every sample brought back from the moon has been contaminated by Earth’s air and humidity […] The chemical and electrostatic properties of the soil no longer match what future astronauts will encounter on the moon.” 2

Whats worse, the solar-charged dust gets thrown up off the moon’s surface via electrostatic forces. The moon doesn’t technically have an atmosphere, but it does have a thin cloud of sharp dust itching to cling to anything it can find.

And it probably isn’t just the moon. “A 2005 NASA study listed 20 risks that required further study before humans should commit to a human Mars expedition, and ranked "dust" as the number one challenge.” 3

The coolest solution I’ve heard about in next-gen spacesuit design is a mesh of woven wires layered into the suit. When activated, the wire mesh would form an anti-static electric field that repels dust. Quite literally a force field. 4

I bet ya'll can help me with this.

I run a lockpicking village, of sorts (more like a cozy lockpicking lounge), at a local event each year.

The whole purpose is to entice femmes, queers and generally people who have been encouraged to consider themselves "non-technical" to play around with this fun hacker hobby.

I do well, but it's very hard to find accessible, friendly lockpicking guides, infographics or information, especially ones that are not gratuitously patriarchal.

Halp? Links?

Hi! I decided to move here from twitter and i'm looking for friends!

i enjoy learning languages & learning about languages -- i'm currently learning japanese, french, and arabic. There are many more i would like to learn if i had the time 😭

I also love anime & manga!! some of my favourite anime are space dandy, hidamari sketch, ojamajo doremi, haibane renmei and the ghost in the shell series.

as for music i mostly listen to rap (of all kinds -- cloud rap, plugg, trap, boom bap, alternative, etc) but I also like shibuya-kei, hyperpop, electronic, jungle, and I love discovering new artists of any genre!

oh yeah also I'm learning to code n stuff but i'm still pretty new to it.

I am currently saving for a new screen drawing tablet as my old one is limiting me and my motor skills aren’t as great as before.

The goal is 170 USD, I can sadly only accept Stripe or BLIK. If I have leftover money after purchase, it will go towards my survival fund

ko-fi page for donation: https://ko-fi.com/crustaceanz

Feel free to support me via donations or by requesting an artwork from me.

Please boost this post, I really would like to receive something nice this season. Thank you

If we've ever met in person and you've wondered "Gee, how did he get this way," I finally have a solid answer.
