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.
Make sure to follow us on Tumblr for your regular dose of space!
If you give a pigeon a little button to peck that releases pigeon food, it will push the button when it's hungry.
If you give a pigeon a button to peck that releases food every 5 pecks, it will peck it more often.
If you give a pigeon a button to peck that releases food at a randomly selected, always shifting number of pecks, the pigeon will peck that fucking button all day long.
Algorithm based social media is not set up to give you the best most fun stuff all the time, it is set up to give you a bunch of stress and nothingness with a randomized reward of something that actually makes you happy, because they want you pecking that button all damn day. It is a slot machine of content, meant to keep you putting in quarters made of your time and attention till you've nothing yet.
At least if I'm having a shit day on my own Tumblr home feed it's because I've made a bad choice about who to follow and I can fix it.
