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.

"When a severe water shortage hit the Indian city of Kozhikode in the state of Kerala, a group of engineers turned to science fiction to keep the taps running.

Like everyone else in the city, engineering student Swapnil Shrivastav received a ration of two buckets of water a day collected from India’s arsenal of small water towers.

It was a ‘watershed’ moment for Shrivastav, who according to the BBC had won a student competition four years earlier on the subject of tackling water scarcity, and armed with a hypothetical template from the original Star Wars films, Shrivastav and two partners set to work harvesting water from the humid air.

“One element of inspiration was from Star Wars where there’s an air-to-water device. I thought why don’t we give it a try? It was more of a curiosity project,” he told the BBC.

According to ‘Wookiepedia’ a ‘moisture vaporator’ is a device used on moisture farms to capture water from a dry planet’s atmosphere, like Tatooine, where protagonist Luke Skywalker grew up.

This fictional device functions according to Star Wars lore by coaxing moisture from the air by means of refrigerated condensers, which generate low-energy ionization fields. Captured water is then pumped or gravity-directed into a storage cistern that adjusts its pH levels. Vaporators are capable of collecting 1.5 liters of water per day.

Pictured: Moisture vaporators on the largely abandoned Star Wars film set of Mos Espa, in Tunisia

If science fiction authors could come up with the particulars of such a device, Shrivastav must have felt his had a good chance of succeeding. He and colleagues Govinda Balaji and Venkatesh Raja founded Uravu Labs, a Bangalore-based startup in 2019.

Their initial offering is a machine that converts air to water using a liquid desiccant. Absorbing moisture from the air, sunlight or renewable energy heats the desiccant to around 100°F which releases the captured moisture into a chamber where it’s condensed into drinking water.

The whole process takes 12 hours but can produce a staggering 2,000 liters, or about 500 gallons of drinking-quality water per day. [Note: that IS staggering! That's huge!!] Uravu has since had to adjust course due to the cost of manufacturing and running the machines—it’s just too high for civic use with current materials technology.

“We had to shift to commercial consumption applications as they were ready to pay us and it’s a sustainability driver for them,” Shrivastav explained. This pivot has so far been enough to keep the start-up afloat, and they produce water for 40 different hospitality clients.

Looking ahead, Shrivastav, Raja, and Balaji are planning to investigate whether the desiccant can be made more efficient; can it work at a lower temperature to reduce running costs, or is there another material altogether that might prove more cost-effective?

They’re also looking at running their device attached to data centers in a pilot project that would see them utilize the waste heat coming off the centers to heat the desiccant."

Time travel fail in which Stan goes back to not break Ford's project, but gets bored waiting for the science fair and decides he might as well give the footbot another try.

He's no McGucket but he knows enough technical mumbo jumbo to make it move at least. If it goes well maybe they let him graduate high school this time around!

Enter the West Coast Tech judges

Genius kid doing genius kid things?

BORING

Worst student the school has ever seen building a fully functional talking robot? The stereotypical dumb boxer kid always overshadowed by his nerdy brother being a secret neglected undiscovered genius? 

THEY CAN SELL THIS! THEIR PR DEPARTMENT WILL LOVE THIS! A TRUE UNDERDOG STORY!

Before Stan has time to process anything he’s already being shipped off California with a full scholarship to be West Coast Tech's new poster child. 

Filbrick: I don’t care how you convinced them you’re worth anything. Don’t fuck this up and earn us millions or you’re not welcome in this house anymore!

Ford is convinced Stan cheated his way into West Coast Tech so they won't get seperated. Ford doesn’t apply to West Coast Tech out of spite. And he's definitely not believing Stan's ridiculous time travel explanation for a second.

Ford becomes obsessed with proving that Stan’s a fraud instead. 

At least they’re still talking. Even if talking means listening to Ford finding flaws in the newest paper Stan was forced to write.

Poor Stan just wants to go home to Gravity Falls and reopen the Mystery Shack

Love Letters from Space

Love is in the air, and it’s out in space too! The universe is full of amazing chemistry, cosmic couples held together by gravitational attraction, and stars pulsing like beating hearts.

Celestial objects send out messages we can detect if we know how to listen for them. Our upcoming Nancy Grace Roman Space Telescope will help us scour the skies for all kinds of star-crossed signals.

Celestial Conversation Hearts

Communication is key for any relationship – including our relationship with space. Different telescopes are tuned to pick up different messages from across the universe, and combining them helps us learn even more. Roman is designed to see some visible light – the type of light our eyes can see, featured in the photo above from a ground-based telescope – in addition to longer wavelengths, called infrared. That will help us peer through clouds of dust and across immense stretches of space.

Other telescopes can see different types of light, and some detectors can even help us study cosmic rays, ghostly neutrinos, and ripples in space called gravitational waves.

Intergalactic Hugs

This visible and near-infrared image from the Hubble Space Telescope captures two hearts locked in a cosmic embrace. Known as the Antennae Galaxies, this pair’s love burns bright. The two spiral galaxies are merging together, igniting the birth of brand new baby stars.

Stellar nurseries are often very dusty places, which can make it hard to tell what’s going on. But since Roman can peer through dust, it will help us see stars in their infancy. And Roman’s large view of space coupled with its sharp, deep imaging will help us study how galaxy mergers have evolved since the early universe.

Cosmic Chemistry

Those stars are destined to create new chemistry, forging elements and scattering them into space as they live, die, and merge together. Roman will help us understand the cosmic era when stars first began forming. The mission will help scientists learn more about how elements were created and distributed throughout galaxies.

Did you know that U and I (uranium and iodine) were both made from merging neutron stars? Speaking of which…

Fatal Attraction

When two neutron stars come together in a marriage of sorts, it creates some spectacular fireworks! While they start out as stellar sweethearts, these and some other types of cosmic couples are fated for devastating breakups.

When a white dwarf – the leftover core from a Sun-like star that ran out of fuel – steals material from its companion, it can throw everything off balance and lead to a cataclysmic explosion. Studying these outbursts, called type Ia supernovae, led to the discovery that the expansion of the universe is speeding up. Roman will scan the skies for these exploding stars to help us figure out what’s causing the expansion to accelerate – a mystery known as dark energy.

Going Solo

Plenty of things in our galaxy are single, including hundreds of millions of stellar-mass black holes and trillions of “rogue” planets. These objects are effectively invisible – dark objects lost in the inky void of space – but Roman will see them thanks to wrinkles in space-time.

Anything with mass warps the fabric of space-time. So when an intervening object nearly aligns with a background star from our vantage point, light from the star curves as it travels through the warped space-time around the nearer object. The object acts like a natural lens, focusing and amplifying the background star’s light.

Thanks to this observational effect, which makes stars appear to temporarily pulse brighter, Roman will reveal all kinds of things we’d never be able to see otherwise.

Roman is nearly ready to set its sights on so many celestial spectacles. Follow along with the mission’s build progress in this interactive virtual tour of the observatory, and check out these space-themed Valentine’s Day cards.

AU In which Ford’s Science Fair Project goes HORRIBLY WRONG-

(And it’s not Stan’s fault this time-)

Handwriting translation:

Stan: “Look Sixer, I’m SURE that whatever doohickey you make- Is gonna knock the SOCKS offa’ those West Coasters”…

*Ford looks sheepish, if not grateful for his twin’s support*

Time skip: Later

*Both Stan and Ford look on at the scene blankly, as 3 soot silhouettes paint the gym floor- Marks of an explosion causing the waxed wooden court to be burnt.*

*Stan and Ford gaze at each other with equal looks of shock and horror*

*A small pile of ash seems to stand for a moment before blowing away. Nobody speaks- Until Stanley breaks the silence. His voice is shaky and hushed- Panic ebbing into his words as we pan to the ashy scene.*

Stan: “The socks are still on, Ford. The SOCKS are STILL on…”

*True to his word, alongside the 3 victims shoes- 3 pairs of white gym socks lay dormant inside of the footwear- And practically unscathed.*

More Everything Forever

I'm on a 20+ city book tour for my new novel PICKS AND SHOVELS. Catch me at NEW ZEALAND'S UNITY BOOKS in AUCKLAND on May 2, and in WELLINGTON on May 3. More tour dates (Pittsburgh, PDX, London, Manchester) here.

Astrophysicist Adam Becker knows a few things about science and technology – enough to show, in a new book called More Everything Forever that the claims that tech bros make about near-future space colonies, brain uploading, and other skiffy subjects are all nonsense dressed up as prediction:

https://www.hachettebookgroup.com/titles/adam-becker/more-everything-forever/9781541619593/

Becker investigates the personalities, the ideologies, the coalitions, the histories, and crucially, the grifts behind such science fictional pursuits as infinite life-extension, space colonization, automation panic, AI doomerism, longtermism, effective altruism, rationalism, and conciousness uploading.

This is, loosely speaking, the bundle of ideologies that Timnit Gebru and Émile P. Torres dubbed TESCREAL (transhumanism, Extropianism, singularitarianism, (modern) cosmism, Rationalism, Effective Altruism, and longtermism):

https://en.wikipedia.org/wiki/TESCREAL

While these are largely associated with modern Silicon Valley esoteric techbros (and the odd Oxfordian like Nick Bostrom), they have very deep roots, which Becker excavates – like Nikolai Fyodorov's 18th century "cosmism," a project to "scientifically" resurrect everyone who ever lived inside of a simulation:

https://en.wikipedia.org/wiki/Nikolai_Fyodorov_(philosopher)

In their modern incarnation, these ideas largely originate in science fiction novels. That is to say, they were made up and popularized by people like me, the vast majority of whom made no pretense of being able to predict the future or even realistically describe a path from the present to the future they were presenting. Science fiction is something between a card trick and a consensual con game, where the writer shows you just enough detail to make you think that the rest of it must be lurking somewhere in the wings. No one in sf has ever explained how consciousness uploading could possibly work, and neither have any of the advocates for consciousness uploading – the difference is that (most of) the sf writers know they're just making stuff up.

Becker's central question is how many "smart" people (some of them very smart and accomplished, others merely very certain that they are smart despite all evidence to the contrary) can mistake futuristic allegories made up by pulp writers for prophesy?

In answering this question, he uncovers a corollary of Upton Sinclair's famous maxim that "it is difficult to get a man to understand something, when his salary depends on his not understanding it," namely, that "it is easy to get a person to believe something when doing so will make them feel good about themselves."

The beliefs that Becker explores in this book sometimes make the believers rich (like the AI grifters who run around shouting about AI taking over the world and turning us all into paperclips). Sometimes, they make their believers feel good about being selfish assholes (like longtermism, which holds that all the misery in the world today is worth it if you can make 24 heptillion hypothetical simulated people just a little happy in 10,000 years). Sometimes, they make their believers feel good about life after death, or eternal life – the same pitch that religions have been roping in followers with since the stone age.

What differentiates these beliefs from other faith-based claims is that their followers claim that they aren't operating on faith, but on science, reason and rationality. This is where the fact that Becker is a bona fide astrophysicist comes in. Not only is he personally qualified to debunk claims about space colonization, but he's also familiar with the rigorous process of scientific inquiry, and capable of consulting experts and listening to them. That's how he concludes, for example, that having your head cut off and frozen when you die is just a form of corpse mutilation, with a zero point zero zero zero zero percent chance of someone recovering your mind from your freezerburned brain.

Like his subjects, Becker has a complicated relationship with science fiction. He, too, enjoys the imaginative flights of the genre, its delightful thought-experiments, its gnarly moral conundra. I love these too. They make for a fascinating and often useful lens for understanding and challenging our own relationship with technology and our very humanity. Ultimately, Becker is exploring the difference between reading sf because it makes you think in new ways, and reading sf as a kind of prophetic text, and – crucially – he's asserting that it's perfectly possible to enjoy this stuff without organizing your moral life around hypothetical heptillions of virtual people living in the year 25,000; or, indeed, having your head cut off and frozen.
