🌞 Prepare to be mesmerized as Aditya-L1, India's remarkable space mission, captures a breathtaking selfie and stunning images of our home planet Earth and the serene Moon! 🚀

ISRO's Aditya-L1 is on a mission like no other, headed for the Sun-Earth L1 point to study the Sun. But it's also treating us to a spectacular visual treat along the way.

Aditya L1 Mission - क्यों है एक वरदान

भारत नें Chandrayaan-3 के बाद कल Aditya L1 Mission से सूर्य को नमन की तैयारी है। भारत की स्पेस एजेंसी ISRO के प्रमुख S. Somanath ने कहा कि भारत का यह पहला सौर Mission सूर्य और पृथ्वी के बीच मौजूद L1 Point पर पहुंचने के लिए 125 दिन लेगा। यह Point अपनी धरती से 15 Lakh Kilometer की दूरी पर है। यह धरती से सूरज की दूरी का मात्र 1% है। Aditya L1 Mission के लिए क्यों खास है L1 Point? किसी भी ग्रह की…

Gonna throw out something crazy. See what sticks. Maybe nothing, hopefully something:

In about 3 months, the US is getting a total solar eclipse. I am a Librarian at a Public Library hosting an event.

Now, I KNOW every corner of the globe has mythology on this very cool astrological event. Many with neat monsters/creatures to go with. It is difficult to find images of said creatures. Sometimes even difficult to find the mythology from various parts of the world. Almost impossible to find coloring pages.

I live in a tiny town, and I am doing everything I can to expand the horizons of the kiddos who live here, and they go bananas for a good story out loud, especially if they have something to do with their hands while listening, like pictures to color in.

I call on the artists of the internet. If you know of a myth about Solar Eclipse, please add on to this post. Tell me the basic myth, tell me the country/culture of origin, and please please please, add a cool picture I can turn into a coloring page. Artist names will be left on pictures for admirers to go look them up, and I hope artists see this as a fun challenge.

I don’t even know if Tumbler in English language has that much of an international presence but… 🤷🏻‍♀️ Here’s hoping.

i designed a sheikah outfit for josha like purah and robbie. they gifted it to her, but josha added the depths elements later because no one tells the president what to do.

i wanted to keep it in line with the modern sheikah's sense of style, with some allusions to their past ninja antics, hence the bandages and assassin's creed hood. all the better to slip out of lookout landing undetected. strict parents make sneaky kids, purah!

Male Cerulean Warbler, Broad-tailed Hummingbird, and Lark Bunting, for Tonelli et al. 2023. Magnetic field disruptions lead migratory birds astray. Always a delight to contribute illustrations to papers like this one! Big thanks to Morgan Tingley for requesting these.

Here are some sketches I drew of Phantasmagoria Corrupted Burning Spice (Change) and Mystic Flour (Volition) :D

Just a fun lil thing while I debate to myself over whether to focus on the world-building or the story. Also Change as a cowboy..just for fun :')

In some villages in Asia, people use the sun's energy to boil water.

A special apparatus angles the sun's rays directly into the kettle, which then causes it to heat water. 🤔

[celestialdaily]

The celestial object of the day is Rhea!

This moon has a really faint atmosphere called the exosphere, which is mainly composed of oxygen. This is the first oxygen atmosphere discovered outside Earth. Its cause? Saturn's magnetic field influencing Rhea.

Liftoff of Starship! 🚀

Starship launches off the pad under the power of all 33 Raptor engines on the Super Heavy Booster.

Happy Dracones Monday! Solar Eclipse!

Happy Dracones Monday! In honour of the solar eclipse I have drawn Apep, or Apophis, the serpent that lives in the dark waters underneath the world who is always trying to eat the sun off Ra's sun boat when he sails into the underworld at night! (Egyptian mythology). Hopefully Ra can fight him off and return the sun to us swiftly!

THINGS I NOTICED IN MY REWATCH PART 2

When I was watching Season 2 episode 5 where Korvo and the Red Goobler fuck, I swear to God I saw a condom... so I freeze framed on every inch of the room they showed.

My thoughts when watching:

At least they were having safe sex

LOL to the bra,... it's probably Korvos right?

the hand cuffs (Korvo or Red Gooblers kink/idea?)

Is that a jug of gasoline or lube? LOL

I love that the red goobler had his shoe taken off at the door, clearly korvo kicked both of his back, but it wasn't until the bed that the Red Goobler kicked off his other shoe LOL was he fucking with one shoe?

again.... CONDOMS?! haha XD

This show is so funny! 🤣

pls i need to provide updates

Moon Missions

What’s going on with the moon?

The United States recently had a solar eclipse on April 8th, 2024, and some might be surprised to learn that the moon is, in fact, affected by solar radiation. The charged particles emitted by the sun, called the solar wind, reach the moon with no interruption from its atmosphere, as it has none. It also has no global magnetic field, another layer of protection that Earth does have, in comparison.

The moon does, however, have small areas of magnetic fields. We can see this because these areas remain lighter in photos whereas chemical reactions from radiation darken the unprotected areas.

Fortunately, most of these charged particles cannot pass through the hulls of space stations, so astronauts are safe in orbit. Cosmic rays, made of stronger and faster-moving particles, are more dangerous. Even on Earth, under the atmosphere and magnetosphere, cosmic radiation reaches humans, though not enough to be considered damaging to our health.

A lander and rover launched in 2018 delivered the first measurements of radiation levels on the moon 4. Based on those data, astronauts on the moon can be exposed to up to 150 times higher radiation levels than on Earth.

Radiation is a leading reason for the pause in lunar landing missions. It raises risks of cataracts, heart diseases, radiation illness, cancer, and other ailments. Longer missions, of course, would heavily exacerbate these radiation doses.

Other Health Concerns

Cosmic rays contain High-Energy (HZE) ions. In different exposure such as from nuclear accidents or irradiation therapy, HZE ions have been found to cause dysregulation in the mitochondria and damage to DNA. Because of this, prolonged exposure is linked to health effects often associated with aging, such as hippocampus synapse loss and metabolic disruption caused by damage to mitochondrial DNA.

Long-duration space flights have also been linked to cardiovascular disorders. For astronauts on the Apollo missions, heart attack was “the second leading cause of death” 8. For additional space flights outside of Earth’s magnetosphere, astronauts also had a higher mortality rate due to cardiovascular diseases.

In a previous article, we discussed the relationship between circadian rhythms and health. These rhythms are another thing that space travel can impact, causing sleep and mental health disturbances in astronauts 9.

While various studies are investigating the conditions of these health risks, a current NASA mission is specifically investigating radiation protection.

Long-term Mission

NASA plans on eventually returning to human-manned missions to the moon.

First, they have to address the issues discussed above.

In November of 2022, Artemis I launched with two manikins bearing radiation detectors. From this mission, NASA was able to confirm the success of the intended trajectory, launch of ground systems, and the Orion spacecraft. The radiation results from this mission are still being analyzed.

The Artemis missions are intended to explore more of the moon than ever before, and lay groundwork for eventual missions to Mars.

Artemis II will not launch any earlier than September of 2025. It is planned to last ten days, consist of a 4-person crew, and be a lunar flyby to ensure the proper functioning of the spacecraft’s systems.

It has seemed for years that lunar exploration has halted. Manned missions have indeed been paused, for good reasons. Ensuring the safety of astronauts is a priority, and they face serious health risks even when missions go as expected. But NASA intends to continue exploring space, the moon, and Mars. The current Artemis missions are discovering improved, new ways to ensure the safety of astronauts while making scientific progress.

The Max-Planck-Institut für Eisenforschung becomes the Max Planck Institute for Sustainable Materials to reflect its solarpunk futures

The Max Planck Institute for Sustainable Materials will explore methods for producing, utilising, and recycling materials in a climate-friendly way.

The  Düsseldorf-based institute has been investigating how to optimise steel and other metallic for applications in energy, mobility, infrastructure, production, and medicine over the past few decades. In recent years, researchers have increasingly directed their focus on how steel and other metallic materials can be produced with minimal greenhouse gas emissions, as well as on maximising the efficiency of limited raw materials for electronic devices, electric motors, and generators.

To reflect this shift in research focus, the Institute has undergone a name change:  it will now be known as the Max Planck Institute for Sustainable Materials.
