#ions — Public Fediverse posts

I found lately this #progmetal band from #Prague called #ions and I’m totally addicted! Even their first album is so good and have such a broad palette of genre specific elements. It’s melodic, it hits hard, it flows so nicely. Just beautiful!

Say this quickly three times - magnetoplasmadynamic thruster!

NASA/JPL successfully tested a new magnetoplasmadynamic (MPD) ion thruster spacecraft engine that runs on lithium metal vapor.

Ion engines accelerate ions — charged atoms — out through a nozzle to provide thrust, hence they are often described as using "electric propulsion" and are 25 times more powerful that current engines that burn chemical propellant.

The test showed the electric propulsion system capable of operating at power levels up to 120 kilowatts. https://www.space.com/astronomy/mars/nasa-is-making-a-powerful-new-ion-engine-to-send-astronauts-to-mars-and-it-just-passed-its-1st-test #NASA #Space #SpaceCraft #MPDEngines #magnetoplasmadynamic #Ions #IonThruster #Lithium

Unlike the easily predictable #radiation ☢️ exposures from flying through the Van Allen Belts or basking in the background flux of #galactic 🌌 cosmic rays, the dose an #astronaut gets from #solar ☀️ activity can vary enormously. Predicting #SpaceWeather remains a decidedly inexact 🔮 #science. High-energy #protons and #ions can tear through metal and flesh alike, damaging #DNA and other delicate cellular machinery. Typically, these showers are linked to #CME https://www.scientificamerican.com/article/space-weather-could-threaten-nasas-artemis-ii-astronauts-during-their-trip/

In 📆 2023, #SpaceX launched the first of its #Starlink V2 Mini satellites 🛰️. These next-generation spacecraft are equipped with #HallEffect thrusters, or #HETs, that operate on #argon, instead of the #krypton propellant on previous Starlinks https://aerospaceamerica.aiaa.org/year-in-review/a-year-of-firsts-for-electric-propulsion

The essential working principle of the #HallThruster is that it uses an #electrostatic potential to accelerate #ions up to high speeds https://en.wikipedia.org/wiki/Hall-effect_thruster#Principle_of_operation

all throughout my life
every atom of mine
has been surrounded
by a cloud

so when I die
do one thing for me
send my atoms away
positively

tear away
each and every cloud
of negativity
send the positive nuclei
speeding through
magnetic fields
nearly as fast as light

"The #bromine in the #restoration #solution initiates spontaneous corrosion upon contact with the aluminum in the spent #battery. During this process, #electrons are released from the corroded aluminum and subsequently transferred to the spent #cathode material."

“To maintain charge neutrality, #lithium #ions in the restoration solution are inserted into the cathode material. This recovery of lithium ions restores the cathode material to its #original state."

Ion thrusters are so cool! 😎 And they'll be operating continuously for about five years.

If only consumer electronics lasted that long...

`For the team of researchers, these results are pretty clear. “Hence, we suggest that GCRs (Galactic Cosmic Rays) and SEP (Solar Energetic Particle) events from the young Sun represent the most effective energy sources for the prebiotic formation of biologically important organic compounds from weakly reducing atmospheres.”`

Australia's Massive Wildfires Shredded the Ozone Layer--Now Scientists Know Why

Massive wildfires that raged across southeast Australia in 2019–20 unleashed chemicals that chewed through the ozone layer, expanding and prolonging the ozone hole.

A study, published today in Nature, describes how smoke combined with chlorine-containing molecules in the stratosphere — remnants of chemicals that are now banned — to cause the destruction.

The Australian fires produced the largest smoke plume on record, releasing roughly one million tonnes of smoke to heights of up to 30 kilometers.

That’s well into the stratosphere, the portion of the atmosphere that contains the ozone layer, which protects Earth from harmful ultraviolet rays, says study co-author Kane Stone, an atmospheric chemist at the Massachusetts Institute of Technology (MIT) in Cambridge.

In the months after the wildfires, the hole in the ozone layer, which appears annually over Antarctica, was larger and lasted longer than in previous years.

About 80% of the chlorine in the atmosphere is a legacy of #chlorofluorocarbons, chemicals used in aerosol sprays and as refrigerants starting in the 1930s.

Their use has mostly been phased out since an international treaty was implemented in 1987. Remnant chlorine is bound up as #hydrochloric #acid and #chlorine #nitrate, which are harmless to the ozone layer.

But when #hydrochloric #acid dissolves in #water droplets, it forms reactive ozone-depleting molecules.

That doesn’t usually happen away from the poles, because the air is too #warm, says Stone.

The team used a computer model to predict how various organic acids contained in smoke particles would alter the solubility of hydrochloric acid.

The changes produced in the simulations mirrored the changes to stratospheric chemistry that were observed after the fires.

Solomon says that #hydrochloric #acid latches onto the #surface of the #smoke #particles and reacts with other molecules to produce #molecular #chlorine, which is broken down in sunlight to highly reactive ‘ozone-eating’ chlorine #ions.

It is also a negatively charged space, a space filled with #ions which supposedly also help a person to feel good. So an idea might not really be as good as you feel about it, while in the #shower.

What's the difference between chlorine, chlorine, and chlorine? Glad that you asked! This is an example of where colloquial English isn't good enough to distinguish between several very different things. We make it easier to understand here -
