Hubble Space Telescope: Exploring the Cosmos and Making Life Better on Earth

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.

Image Sensors Find Cancer

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.

Laser Vision Gives Insights

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.

Optimized Hospital Scheduling

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.

Optical Filters Match Wavelengths and Paint Swatches

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.

Following an accident, Danny wakes up in Gotham City in a DC universe. Lacking any forms of ID or possessions beyond the clothes on his back, he’s forced to commit some crimes to survive. Minor crimes, but still.

And then he gets caught.

During the court proceedings, they come to the mistaken conclusion that he’s a Meta suffering from some psychiatric issues such as Cotard’s Syndrome (a real rare condition where a person holds the delusional belief that they’re dead/don’t exist/etc).

Thus, between his “need for mental treatment” and the concerns about housing someone with his unique physical traits, he is sentenced to spend time in Arkham Asylum. He’s under pretty low security aside from the anti-Meta stuff and has more freedoms than some other inmates, but it’s still not a great experience. Even at the best of times, Arkham is hardly a nice place.

Some of his fellow residents are decently chill all things considered, but lots very much aren’t.

Plan 99's anniversary rough concept

[cheeky-peach-sims]

Hi Simmers! This is my second legacy challenge called the Sims Townie Legacy Challenge

The 25th anniversary of the Sims series and the re-release of the Sims and Sims 2 inspired me to create this legacy. Throughout the years the iconic townies and family's lore has made the game so special. With so many timelines for characters such as Bella Goth or the Landgraabs I combined all versions of these Townies for each generation, as well as added some fan favorites from the Sims 3 & 4. Use hashtag #STLC or #SimsTownieLegacy if you decide to play! Happy Simming :)

See my current progress of the legacy here

I made a little edit to generation 4 - pollination technician #9. I felt like I didn’t add as much goals as I should!! But anyways carry on lol

Fenton Coded

Tim... Tim just stared.

He...

Huh.

He had once entertained the idea that he wasn't really a Drake, a very long time ago when he overheard his mom and dad arguing and some words were said in the heat of the moment, but to be honest Tim always thought the obvious culprit of anyone being his dad would most likely be Bruce (Bruce even admitted he had a small fling with his mother but that was two years before her marriage)

But before little Tim's curiosity could really take hold on the idea, he had saw on the news Robin performing a Grayson flip and the hint of Tim not being a Drake left his mind. Robin was Dick Grayson! And if he was Robin that had to mean Bruce Wayne was Batman!

Then well... his stalking of the Bats started and the rest became history.

But now, as Tim was staring at his own DNA test, something he never bothered to do until that damned Demon brat wanted to make sure he was ONLY blood son of Bruce (and doing a DNA test something even Bruce never thought of doing due to well… how he was towards Tim during his first months as Robin)

He well…

He kinda needs to find out who this Daniel Jackson Fenton is.

(Tim finds out he isn’t a Drake, but also not a Wayne (because Damian wanted to make sure he was only blood son) but is instead a Fenton)

i know that uhura’s role in tos was written to be like a radioman (the guy in wwii movies who carries the phone on his back sometimes) meaning that the “communications officer” role evolved from radioman to linguist in the time since tos aired. but that makes uhura in tos really interesting with a retrospective read of her character, applying things novels and later iterations of her have fleshed out, because she doesn’t do any visible linguistic work in any tos episode. she does security and navigation and piloting and engineering which sort of makes her seem like a valuably flexible sort of many-skilled officer.

it was probably both enterprise with hoshi and the 2009 movie that really cemented the idea of “communications officer means linguist or at the very least polyglot” instead of it just being an uhura-quirk. uhura in the 2009 movie does a lot of engineering/operating work of comm equipment and is implied to speak a lot of languages on top of be able to interpret subspace “noise,” so to speak (like, there’s no way it’s radio. it can’t be radio. star trek takes place across distances of lightyears—when they say “signal,” i’m assuming it’s not radio). and of course strange new worlds has run with the linguistics angle and made it even more explicit that yes she studies linguistics, linguistics is a core part of starfleet academic infrastructure, to the point where whole episode plots are written around the act of translation.

the retrospective addition of this expertise to uhura makes what she is in tos a character even more focused on leadership and, idk, becoming something like a captain, because she doesn’t seem all that specialized. she’s more of a kirk-like character, or janeway or sisko, characters that have a specialized skill but have set it aside mostly to pursue some sort of command. obviously this wasn’t the intention of her character. writers of uhura have mostly just stumbled on the idea of her as a polyglot (according to wikipedia, first introduced in the novel uhura’s song, so) and been like “neat idea! makes sense! explorers need to learn languages!” and kept doubling down on that idea until we get to an origin-story uhura in snw that (wildly) speaks 37 languages, for whatever definition of speak or language, i guess.

what all this overthinking on my part has generated is this idea of uhura very much like a futuristic-captain aubrey or a captain sisko not nailed down to one station, hanging off the shrouds of a solar-sail ship’s rigging, looking beyond, in the most romantic and idealized version of an explorer. i think a lot of people read/write female characters as being more down-to-earth than the whimsical leader-on-the-sea or more nurturing than than the hardened captain-of-a-ship, partly why janeway and burnham are so wonderful to me. but it’s fun to imagine tos uhura being the exploring-captain archetype, amongst the political structures of the 60s. like the additions to her character over the years have solidified that romantic adventurer portrait of her in tos, when the idea of her in command would be the least welcome.

and the fact that she was shown to be excited about a solar sailing ship in snw, like sisko was in ds9 for that one episode, i think emphasizes this read of her—and that her character-journey in snw is going to be how she goes from bookish linguist to “hanging-on-a-shroud-on-a-sunsail-ship” looking out to “sea”.

Setting Sail to Travel Through Space: 5 Things to Know about our New Mission

Our Advanced Composite Solar Sail System will launch aboard Rocket Lab’s Electron rocket from the company’s Launch Complex 1 in Māhia, New Zealand no earlier than April 23, at 6 p.m. EDT. This mission will demonstrate the use of innovative materials and structures to deploy a next-generation solar sail from a CubeSat in low Earth orbit.

Here are five things to know about this upcoming mission:

1. Sailing on Sunshine

Solar sails use the pressure of sunlight for propulsion much like sailboats harness the wind, eliminating the need for rocket fuel after the spacecraft has launched. If all goes according to plan, this technology demonstration will help us test how the solar sail shape and design work in different orbits.

2. Small Package, Big Impact

The Advanced Composite Solar Sail System spacecraft is a CubeSat the size of a microwave, but when the package inside is fully unfurled, it will measure about 860 square feet (80 square meters) which is about the size of six parking spots. Once fully deployed, it will be the biggest, functional solar sail system – capable of controlled propulsion maneuvers – to be tested in space.

3. Second NASA Solar Sail in Space

If successful, the Advanced Composite Solar Sail System will be  the second NASA solar sail to deploy in space, and not only will it be much larger, but this system will also test navigation capabilities to change the spacecraft’s orbit. This will help us gather data for future missions with even larger sails.

4. BOOM: Stronger, Lighter Booms

Just like a sailboat mast supports its cloth sails, a solar sail has support beams called booms that provide structure. The Advanced Composite Solar Sail System mission’s primary objective is to deploy a new type of boom. These booms are made from flexible polymer and carbon fiber materials that are stiffer and 75% lighter than previous boom designs. They can also be flattened and rolled like a tape measure. Two booms spanning the diagonal of the square (23 feet or about 7 meters in length) could be rolled up and fit into the palm of your hand!

5. It’s a bird...it’s a plane...it’s our solar sail!

About one to two months after launch, the Advanced Composite Solar Sail System spacecraft will deploy its booms and unfurl its solar sail. Because of its large size and reflective material, the spacecraft may be visible from Earth with the naked eye if the lighting conditions and orientation are just right!
