i hate that every time i look for color studies and tips to improve my art and make it more dynamic and interesting all that comes up are rudimentary explanations of the color wheel that explain it to me like im in 1st grade and just now discovering my primary colors

Does anybody have that image of what cyberpunk dialogue is like. "to crack a cyber lemon this nasty" or whatever

the problem with autism is sometimes you want to do something (brave) but you need someone to gently walk you through each step so you know what will happen. and people don’t like doing that

bitches be like "these are my comfort characters!" and it's a group of murderers

Southern Comfort (2001)

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!
