Take the hinges of a door and reattach them on the other side, so that the handle-wards edge of the door is now the side attached to the frame.

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!

Epic horror game idea

So whenever visualizing higher dimensions it's difficult to have them make sense, but this leads to it being hard to understand and therefore unknown and that makes it scary....

Hyperbolic spaces are also hard to understand, but in short they have more than 360° around a point and all lines diverge.

These effects stack...

Regular 2D space

4 squares around a point

Hyperbolic 2D space

5 squares around a point

Regular 3D : 8 cubes

Hyperbolic 3D : 20 cubes

And so on it goes

I have devised a way to visually show how far an object is just from how it looks in 3 more spatial dimensions

I propose the following setup

Hyperbolic 6D space with 1280 around each corner

Coordinates

X Y Z are shown in the normal way

U is shown through change in colour, with green objects being on the same layer as you. They would fade into Yellow,Orange and stop at Red, on the other side they would Teal, Blue and then stop at Indigo/Violet.

V is shown through saturation, with completely white and black being the opposite far ends and regular as your current location.

W is shown through blur, in which there is No blur at your location and at opposite ends in each direction are Horizontal and vertical blur of the lines that make up an object's surface.

Of course for this to work the game would have a very minimalist art style where the objects are made of only voxel art.

Also since the colours are being used to show distance in the U coordinate it has to be in monochrome.

Then with this setup create a space you have to navigate while a monster is chasing you and you have to solve puzzles. Possibly it could be a metroid vania.

This will make players extremely prone to being lost if they do not get their head around navigating the absolute acid trip that hyperbolic 6D space would be.

While taking a nap today I dreamt there was a hazard sign called "never found" which was used to indicate a location where people disappeared never to be seen again
