HOLY SHIT

Roman's primary structure hangs from cables as it moves into the big clean room at NASA's Goddard Space Flight Center.

What Makes the Clean Room So Clean?

When you picture NASA’s most important creations, you probably think of a satellite, telescope, or maybe a rover. But what about the room they’re made in? Believe it or not, the room itself where these instruments are put together—a clean room—is pretty special. 

A clean room is a space that protects technology from contamination. This is especially important when sending very sensitive items into space that even small particles could interfere with.

There are two main categories of contamination that we have to keep away from our instruments. The first is particulate contamination, like dust. The second is molecular contamination, which is more like oil or grease. Both types affect a telescope’s image quality, as well as the time it takes to capture imagery. Having too many particles on our instruments is like looking through a dirty window. A clean room makes for clean science!

Two technicians clean the floor of Goddard’s big clean room.

Our Goddard Space Flight Center in Greenbelt, Maryland has the largest clean room of its kind in the world. It’s as tall as an eight-story building and as wide as two basketball courts.

Goddard’s clean room has fewer than 3,000 micron-size particles per cubic meter of air. If you lined up all those tiny particles, they’d be no longer than a sesame seed. If those particles were the size of 16-inch (0.4-meter) inflatable beach balls, we’d find only 3,000 spread throughout the whole body of Mount Everest!

A clean room technician observes a sample under a microscope.

The clean room keeps out particles larger than five microns across, just seven percent of the width of an average human hair. It does this via special filters that remove around 99.97% of particles 0.3 microns and larger from incoming air. Six fans the size of school buses spin to keep air flowing and pressurize the room. Since the pressure inside is higher, the clean air keeps unclean air out when doors open.

A technician analyzes a sample under ultraviolet light.

In addition, anyone who enters must wear a “bunny suit” to keep their body particles away from the machinery. A bunny suit covers most of the person inside. Sometimes scientists have trouble recognizing each other while in the suits, but they do get to know each other’s mannerisms very well.

This illustration depicts the anatomy of a bunny suit, which covers clean room technicians from head to toe to protect sensitive technology.

The bunny suit is only the beginning: before putting it on, team members undergo a preparation routine involving a hairnet and an air shower. Fun fact – you’re not allowed to wear products like perfume, lotion, or deodorant. Even odors can transfer easily!

It takes a lot of specialists to run Goddard’s clean room. There are 10 people on the Contamination Control Technician Team, 30 people on the Clean Room Engineering Team to cover all Goddard missions, and another 10 people on the Facilities Team to monitor the clean room itself. They check on its temperature, humidity, and particle counts.

A technician rinses critical hardware with isopropyl alcohol and separates the particulate and isopropyl alcohol to leave the particles on a membrane for microscopic analysis.

Besides the standard mopping and vacuuming, the team uses tools such as isopropyl alcohol, acetone, wipes, swabs, white light, and ultraviolet light. Plus, they have a particle monitor that uses a laser to measure air particle count and size.

The team keeping the clean room spotless plays an integral role in the success of NASA’s missions. So, the next time you have to clean your bedroom, consider yourself lucky that the stakes aren’t so high!

that crunchy vibe that 70s/80s movies have that modern movies simply cannot capture… that kind of quiet empty vibe to em that can be played for either bleakness or a peaceful energy… why do all modern movies (even the great and pretty ones) feel overproduced after watching an older film. what is it I can’t put my finger on it but it’s there I can feel it

Lots of my favorite vines are old ones, so here are some that I didn’t want lost to the wind

Might make part 2 w/more modern vines(?)

can anyone on this gay ass website give me an opinion on which translation of the epic of gilgamesh i should read? ive been wanting to read it for ages but theres a number of common translations and i know translations can make or break a story; i dont want to start with the wrong one

i watched one (1) video on how to draw hands that changed my life forever. like. i can suddenly draw hands again

these were all drawn without reference btw. i can just. Understand Hands now (for the most part, im sure theres definitely inaccuracies). im a little baffled

HOW TO SUCK DICK

If you simply wanted to get a guy off as quickly as possible, all you need to do is lock your lips at the base of his cock and suction them up and down the bottom ¾ of his shaft at a quick, steady pace while pressing your flattened tongue against the underside of his dick. Make sure you are applying pressure with both your lips AND tongue. Keeping your tongue engaged at all times is key. I try to keep mine moving at all times. This is how you get 90% of guys off. It helps me keep from gagging to hold his cock steady at the base and bring my lips down to meet my fingers. You can do this very slowly for a more intense feeling, but make sure you move at a steady rhythm. Some guys like it faster or slower; you may have to ask, or more likely, he’ll tell you. This is your power move, the one that is actually going to bring him to orgasm. A true hooker blowjob needs only this one move; if scientists were to create a blowjob machine, this is what it would do. The other moves I’m going to teach you are artistic flourishes; you use them to add flair and style to your blowjob or to slow down the action a little. SALIVA Don’t be afraid to just slobber all over his love muscle. It should be as wet and sloppy as possible, especially during your power move. A good blowjob makes loud, gross suction-y noises. When I’m done, I’m usually covered in my own drool and leave a wet spot on the bed. USING YOUR HANDS If his dick is too big for you to take the whole thing in your mouth, you’ll need to use your hand too. Slobber all over his cock for awhile first so your hand will slide easily up and down instead of just catching on his dry skin. The most important hand move is the twister. When you slide your hand up his shaft, twist your wrist. A twisting motion gets you into a smoother rhythm than the straight up and down. Slide your hand up and down on the base of his cock in conjunction with your mouth moving up and down on the rest of it. The hard part is finding the correct grip: again you may want his guidance. Another good trick is to wrap your hand around the top of his cock and put your mouth over your hand. Then slide your hand down the shaft and your mouth down on top of it in a fluid motion until your hand meets the base of his cock. It will feel like you’re sliding your mouth all the way down him even if you can’t. It’s times like these I wish I could draw; I’d make little diagrams. THE BALLS I usually start out by paying some attention to the balls. There are three basic ball moves: you can put them in your mouth and suck them (LIGHTLY), lick them with a flattened cow tongue, or tense your tongue into a point and run the tip of your tongue all over them. I alternate between all three. Sometimes I lift them up and lick underneath his balls. Also, if you cup them while you are entering the home stretch, you’ll be able to tell he’s about to cum as they get higher and tighter. THE HEAD My next move is usually to give his shaft several long licks from base to tip. This is the ice cream cone move; it looks sexy, it’s a nice touch, but it’s not going to make anybody cum. While conducting the power move, I come up from time to time to give the head a little attention: sucking on it, moving my tongue in a circle around it, and flicking my tongue over that spot on the underside that all the sex websites tell you is el sensitivo. In my experience, guys don’t really go that wild over attention to that spot, but these are just flourishes anyway. I tend to get a bit wrapped up in my work that I forget to make eye contact, so head action is a great time to look up at him with puppy dog eyes and his cock in your mouth. FACE SLAPPING I mentioned this in my tips to get him to cum faster, but at least once during the beej, I usually pop his dick out of my mouth and slap it against my tongue or face, then look at him while I rub his cock against my cheeks and lips. Guys are visual, this is just a little something dirty for him to look at. DEEP THROAT I can’t really teach you how to deep throat, that’s between you and your gag reflex. The important thing, I think, is to make an effort to take him in as deep as you can, even if it’s only for a few seconds. It’s hard to explain exactly how I do this: try concentrating on relaxing your throat and jaw. As I mentioned before, it helps me to steady his cock with my hand when I go deep, and breathing in instead of just holding your breath also helps abate that “gonna puke” feeling. THE BIG FINALE When you’re ready to finish him off, go into the power move and don’t vary your pace for anything. If you’re cupping his balls, you’ll often be able to tell when he’s about to cum as they tighten up. I speed up a little bit at the end, and when I feel him start to come I push my head down as deep as it will go and suck slowly and intensely at the base, letting his cum just shoot down my throat.
