The Sound That Shook The World

August 27, 1883: the earth makes the loudest noise, louder than any it has made since. A volcano on Krakatoa was erupting and it did so with a bang. Literally – the sound was so loud, it was heard across a thirteenth of the globe. If you were in Washington, DC and heard a noise coming from Philadelphia, that would be incredible. But those cities are just 140 miles apart. Krakatoa was heard 3,000 miles away. It would be like if you were in Washington, DC and heard a noise coming from Dublin!   

A barometer at the Batavia gasworks (100 miles away from Krakatoa) registered the ensuing spike in pressure at over 2.5 inches of mercury. That converts to over 172 decibels of sound pressure. A jackhammer is about 100 decibels, and a jet engine is about 150 decibels.  To register as 172 decibels, 100 miles away? People’s eardrums must have been shattering.

Put to the Test: Orion Service Module

Blasted with sound, shaken for hours and pyro detonated, the Orion Service Module Completes Ground Tests at our Glenn Research Center

We recently completed a structural integrity evaluation on the test version of the Orion service module at our Plum Brook Station in Sandusky, Ohio. Designed to ensure the module can withstand launch atop the Space Launch System (SLS) rocket, the battery of tests was conducted in stages over a 16-month period.

The 13-ton European service module will power, propel and cool Orion, while supplying vital oxygen and water to its crew during future missions.

The Powerhouse: Space Launch System and Orion

Our Space Launch System is an advanced launch vehicle that will usher in a new era of human exploration beyond Earth’s orbit. SLS, with its unparalleled power and capabilities, will launch missions to explore deep-space destinations aboard our Orion spacecraft.

What is Orion? Named after one of the largest constellations in the night sky and drawing from more than 50 years of spaceflight research and development, the Orion spacecraft will be the safest, most advanced spacecraft ever built. It will be flexible and capable enough to take astronauts to a variety of deep destinations, including Mars.

Welcome to the Buckeye State

In November 2015, the full-sized test version of the Orion service module arrived at Cleveland Hopkins Airport aboard an Antonov AN-124. After being unloaded from one of the world’s largest transport aircraft, the module was shipped more than 50 miles by truck to Plum Brook for testing.

Spread Your Wings

The first step of the service module’s ground test journey at Plum Brook’s Space Power Facility, saw one of its 24-foot solar array wings deployed to verify operation of the power system. The test confirmed the array extended and locked into place, and all of the wing mechanisms functioned properly.

Can You Hear SLS Now?

The SLS will produce a tremendous amount of noise as it launches and climbs through our atmosphere. In fact, we’re projecting the rocket could produce up to 180 decibels, which is louder than 20 jet engines operating at the same time.

While at the Reverberant Acoustic Test Facility, the service module was hit with more than 150 decibels and 20-10,000 hertz of sound pressure. Microphones were placed inside the test environment to confirm it matched the expected acoustic environment during launch.

After being blasted by sound, it was time to rock the service module, literally.

Shake Without the Bake 

Launching atop the most powerful rocket ever built – we’re talking more than eight million pounds of thrust – will subject Orion to stresses never before experienced in spaceflight.

To ensure the launch doesn’t damage any vital equipment, the engineering team utilized the world’s most powerful vibration table to perform nearly 100 different tests, ranging from 2.5 Hz to 100 Hz, on the module in the summer of 2016. 

Gotta Keep ‘Em Separated

The team then moved the Orion test article from the vibration table into the high bay for pyroshock tests, which simulated the shock the service module will experience as it separates from the SLS during launch.

Following the sound, vibration and separation tests, a second solar array wing deployment was conducted to ensure the wing continued to properly unfurl and function.

Headed South for the Summer

The ground test phase was another crucial step toward the eventual launch of Exploration Mission-1, as it validated extensive design prep and computer modeling, and verified the spacecraft met our safety and flight requirements.

s12e14: The Raid. Episode Coda.

Dean sits on his bed.

Usually, with shit like this happening, he’d want to move. Stress clean, buy groceries, go for a drive. Instead, he sits, a lead weight in his stomach keeping him in place. Guilt, but not. There’s an edge of sadness to it that is making his throat hurt, that has him try and find comfort in his room, his one and only safe space. Disappointment, then. But worse.

He’s disappointed with himself.

Dean’s been trying not to feel that way. Really, fuck, all the way back home he’s been trying so hard—he had to forgive Ma-his mom, she was right and he was. Was not. He shouldn’t feel disappointed with himself that he’d apologized. She’s their mom and that’s more important than how Dean’s stupid fragile feelings were hurt. Except, every time he repeats that to himself the lead weight gets heavier.

He’d tried, all through dinner. Fuck, did he try. They’re a family and families eat together. But the food just didn’t wanna go down. As if there were still words locked in his throat, words of hurt and accusation, and they were in the way. The more he tried to get past them, the harder it got to talk. Like his insides were torn between heaving it all up and keeping everything inside. He’d played it off as just being tired, and Sam and their mom had shared that look. Like they were bonding over their mutual exasperation over Dean’s juvenile avoidance strategies. Plotting behind his back over how they’re gonna work to make Dean more civilized, make him see reason.

Like planning to take out entire species is fucking civilized behavior.

And now he’s being unfair. But still. Or, hell, maybe Dean’s just plain wrong about this and they’re right. Somehow. At least that’d fit the pattern.

Dean puts his face in his hands. Rubs his temples, swallows his spit. His throat feels stuffed.

There’s light on in his room and his door is closed and the sheets he’s sitting on are fresh and soft. Sometimes, concentrating on these things helps a bit. Dean focuses on breathing slow and into his stomach. He kind of wishes Cas were here. Talking doesn’t help shit when you’re not heard.

Cas can pick Dean’s heartbeat out of a crowd.

They could be walking down a crowded street, or standing in a roaring stadium, or sitting in the cardiology unit of the local hospital, and Cas would easily know which thumping beat belonged to Dean Winchester.

“Does anyone have any questions?” Professor Negan spoke, his voice deep and gravelly. Nobody spoke so he continued to clean the blackboard while the rest of the class began to pack up their things and begin to leave the room.

I was at the back, as usual, trying to avoid the attention of others. The girls that surrounded me always teased me for being the quiet one who always gets the highest grades. Sure, I always got A+’s but I worked for it.

The girls that surrounded me were the popular girls who were effortlessly beautiful and were caked in makeup whereas I preferred a more natural look. They were loud and giggly and always tried to gain the attention of Professor Negan. He was foul-mouthed and perfect. His black hair, graying beard, and hazel eyes were the combination to my heart. Yet I was shy remember and therefore have never spoken to him, except one time when I stuttered my way through it and then ran away embarrassed and have yet to speak to him since.

Thanks for the prompt! Enjoy! :-) xxxx

*****

* Dex leaves the Haus early every night.  Usually a few hours earlier than anyone else.  On roadies he heads up to his room at 7 o’clock sometimes, or goes for a walk.

- The team don’t want to pry, but were confused, concerned, and a little nosy.  They have found out he’s on the phone to someone he’s close to, because they’ve overheard him saying “love you lots” a few times.

- So they figure he’s probably talking to a girlfriend.

Your fingers ran along the golden feathers of Gabriel’s wings, each stroke eliciting a soft whimper. Blood stained in patches under the deep gashes you tended to; red rivers running through golden valleys. Each touch was a mix of pain and pleasure for him, your fingers tinted from patching up his wounds. He hissed at the pressure, only for the sound to evolve into a low moan when you stroked him sorrily.

“You’re not careful enough.” You scolded him quietly. “You could’ve been killed.”

“What, no ‘thank you Gabriel’? No ‘you’re my hero Gabriel’?” He scoffed, his fiery eyes capturing your attention.

You sent him a sweet smile, leaning over to place a light kiss on his cheek. “Thank you, glorious Gabriel, son of God and all-powerful archangel, I owe you my life.” You pronounced. Gabriel rolled his eyes at your mocking eccentricity. “But really. Thank you.” You huffed. “I’d be dead if it weren’t for you.”

“You’re welcome.” He smiled brightly, although his mouth fell into an open state as you whisked your fingers across the tops of his wings. “zol ta fa” he cursed under his breath in Enochian.

Service dragons!

Dragon guides for blind people, complete with a little harness that won’t affect wing movement if they have wings.

Emotional support dragons for people with PTSD or anxiety; they sense an oncoming panic or flashback episode and guide the person to calmness or help them stay grounded if they dissociate / derealize / depersonalize.

Seizure dragons to help people with epilepsy or seizure disorders; they sense a seizure coming on and take care of the person. (What is done would depend on the type of seizure.)

Support dragons for autistic people; they do things like lead the person someplace quiet if they sense sensory overload and they’ll curl around the person for pressure stimulation, purr (vibration / sound) or offer their head or back or tummy for petting as a calming tactile stim.

Service dragons that help people with limited or no hand use; they go fetching things or helping them around the house and assisting them when they’re out and about.

And so on and so on…

“Moonlight,” he whispers, delicately brushing the hair from my face.

The simple endearment coupled with the feel of his fingers against my skin send me spiraling into a frenzy I don’t think I ever want to return from.

No longer tentative, he shifts forward. His full lips press soft and warm against mine, effectively ruining me for anyone else in this world but him.

I’m lost in the contact, giving myself over to him while his thumb draws a line along my jaw.

Kissing Tybalt - A birthday gift for @xerxia31

Today is the day, the big day of @xerxia31. You know her as an awesome writer, an impeccable beta ( the Queen of Red Pencil), but most importantly, I know her as a friend - and here I lack words and superlatives to describe what her friendship means.

With the help of @burkygirl for the betaing (and there was a lot, thank you so much for helping me) and the amazing art @akai-echo did for this story, here is my humble birthday gift.

Have the bestest of days, my friend !

KISSING TYBALT

“How do you feel about kissing Tybalt?”

How do I feel about kissing my friend on stage ? Last I checked, the script says nothing about exchanging saliva with Tybalt. Well, technically with Peeta. My friend, who’s playing Juliet’s cousin in this musical he dragged me into.

“Uh-” is all I manage to say. I’m so eloquent, right? But what can I say? Maybe something like: Shouldn’t we have discussed it  more than three days before the premiere of the show? But that’s how our director, Effie, is. Crazy. She has two thousand brilliant ideas just like this one on a bad day. Don’t get me started on how many she has on a good day.

Fractured Light - A  Kalagang Oneshot

Okay, this is probably trash. But it wouldn’t leave me alone.

Rated M: Mature Situations

Note: I own nothing related to Sense8 or its characters, nor am I profiting from this writing.

Author’s Note:

This is my first foray into Kalagang fanfiction. Actually, this is my first Sense8 fanfiction ever.  

Fractured Light was inspired by the events at the end of Season 2 (where I think I might have died a little death). I don’t even try to speculate on how the cluster would have gotten Wolfgang out of BPO - that’s for another fanfic. Instead, I focus on the aftermath, in Paris, during what I imagine to be Wolfgang’s recover period.

The stars, the moon, they have all been blown out

You left me in the dark

No dawn, no day, I’m always in this twilight

In the shadow of your heart

  • from Cosmic Love by Florence and the Machine

Wolfgang’s chest still ached even after nearly a week from being rescued from the BPO facility in Berlin. There was also a general soreness to his muscles that still made it hard for him to get out of bed in the morning. But he never complained about the residual pain from the electric shock.  Kala knew these things only because it was in their special nature to know these things about each other. He couldn’t hide the pain from her, even when he tried.

Just as she couldn’t hide her longing from him.
