In the 35 years since its launch aboard space shuttle Discovery, the Hubble Space Telescope has provided stunning views of galaxies millions of light years away. But the leaps in technology needed for its look into space has also provided benefits on the ground. Here are some of the technologies developed for Hubble that have improved life on Earth.
Charge-coupled device (CCD) sensors have been used in digital photography for decades, but Hubble’s Space Telescope Imaging Spectrograph required a far more sensitive CCD. This development resulted in improved image sensors for mammogram machines, helping doctors find and treat breast cancer.
In preparation for a repair mission to fix Hubble’s misshapen mirror, Goddard Space Flight Center required a way to accurately measure replacement parts. This resulted in a tool to detect mirror defects, which has since been used to develop a commercial 3D imaging system and a package detection device now used by all major shipping companies.
A computer scientist who helped design software for scheduling Hubble’s observations adapted it to assist with scheduling medical procedures. This software helps hospitals optimize constantly changing schedules for medical imaging and keep the high pace of emergency rooms going.
For Hubble’s main cameras to capture high-quality images of stars and galaxies, each of its filters had to block all but a specific range of wavelengths of light. The filters needed to capture the best data possible but also fit on one optical element. A company contracted to construct these filters used its experience on this project to create filters used in paint-matching devices for hardware stores, with multiple wavelengths evaluated by a single lens.

HAPPY EUROPA CLIPPER LAUNCH DAY
renee minkowski I think about you every day
you’ll never guess what I just started listening to
something something the poetry of science etc
the whimsical boy genius has been hanging out by the monolith outside town too much and now all his charming inventions are made out of jagged black iron and animal carcasses
your tumblr avatar is who you are on the outside, and your discord avatar is your true self
the purpose of friends is to have people who unconditionally hate your shitty exes & relatives. like maybe YOU have a complex relationship with your father but i sure don't. i'm outside his house with a gun. he's not the unforgivable asshole who raised me he's just an unforgivable asshole
I got 38 and I love the color yellow
25% of the people have a 4th cone and see colors as they are
Given the sudden interest for the color of dresses and vision, here some of the fascinating findings we did recently.
The color nuances we see depend on the number and distribution of cones (=color receptors) in our eye. You can check this rainbow: how many color nuances do you count?
You see less than 20 color nuances: you are a dichromats, like dogs, which means you have 2 types of cones only. You are likely to wear black, beige, and blue. 25% of the population is dichromat.
You see between 20 and 32 color nuances: you are a trichromat, you have 3 types of cones (in the purple/blue, green and red area). You enjoy different colors as you can appreciate them. 50% of the population is trichromat.
You see between 33 and 39 colors: you are a tetrachromat, like bees, and have 4 types of cones (in the purple/blue, green, red plus yellow area). You are irritated by yellow, so this color will be nowhere to be found in your wardrobe. 25% of the population is tetrachromat.
You see more than 39 color nuances: come on, you are making up things! there are only 39 different colors in the test and probably only 35 are properly translated by your computer screen anyway :)
It is highly probable that people who have an additional 4th cone do not get tricked by blue/black or white/gold dresses, no matter the background light ;)
