Am I misreading this paper? It appears to propose that mining/drilling/fracking/extraction as a source of hydrocarbon will be less profitable than using solar power to harvest CO2 from the atmosphere and turn it into methane, within the next decade.

Not "we need to regulate extraction out of existence." Just "the market will make drilling unprofitable."

The reason I'm asking is because if this tech displaces extraction as a source of carbon fuels, that's a cap on the amount of CO2 introduced to the biosphere, which puts an upper limit on global warming. It feels like hope.

(there's lots of other reasons why this tech is neat. but that's the one I'm highlighting.)

Terraform Industries wants to solve climate change by making more hydrocarbons

Casey Handmer is not intimidated by very large quantities. Billions of acres. Thousands of gigawatts of solar power. A billion tons of carbon. His startup, Terraform Industries, aims to operate at these ambitious scales. The company wants to transform hydrogen and atmospheric carbon into synthetic natural gas on a large scale. That’s more than a little mind-boggling, considering the startup is…

Terraform Industries wants to solve climate change by making more hydrocarbons

Casey Handmer is not intimidated by very large quantities. Trillions of acres. Thousands of gigawatts of solar power. A billion metric tons of carbon. His startup, Terraform Industries, aims to operate at these ambitious scales. The company wants to turn hydrogen and atmospheric carbon into synthetic natural gas at scale. It’s more than a little mind-boggling, given that the startup is scarcely…

Hubble'ın 32 yıl boyunca yaptığı tüm çekimler birleşti, ortaya işte bu harika manzara çıktı

NASA geçtiğimiz günlerde Hubble müşahedelerinin 32’inci yılını kutladı. Uzay teleskobu 1990 yılında uzaya fırlatılmıştı. Fırlatılmasından bu yana 1,4 milyondan fazla müşahedesi tamamladı. Casey Handmer isimli bir fizikçi ise, kısa müddet evvel tüm bu müşahedeleri tek bir nefes kesici imgede birleştirdi.

Handmer, imgeyi Nisan ayında Twitter’da paylaştı. Başlangıçta dört kesim halinde paylaşılan bu imajlara daha sonra, Hubble müşahedelerinin tamamının birbirine bağlı olduğu öteki bir tweet eklendi.

Bu imgenin katiyen baş döndürücü olduğunu ve gökyüzünün muazzam boyutunu gösterdiğini söyleyebiliriz. Hatta Handmer, Hubble’ın gökyüzünü düşündüğünüz kadar gözlemlemeyi bile başaramadığını belirtiyor.

And here's one that's a bit easier to see on Twitter. pic.twitter.com/dlNS5jbod3

Handmer, Twitter’da “Hubble’ın görüş alanı 202 yay saniyesidir” dedi. Bu yüzden de gökyüzünü büsbütün kaplamanın yaklaşık 3,2 milyon müşahede gerektireceğini beliriyor. Manzaraları birleştirdiği sırada 1,4 milyondan fazla Hubble müşahedesi tamamlanmıştı.

Fakat Hubble 1,4 milyondan fazla müşahede yapmış olsa da, birçok vakit bir alanı birden çok sefer gözlemlediğinden ötürü gökyüzünün yarısını gözlemlemeyi başarmış değil. Hubble’ın gerçekte ne kadar gördüğünü merak eden Handmer, Astropy.org’dan dataları alarak bir imgede derlemeye başladı. Toplamda, Hubble’ın şu ana kadar gökyüzünün sırf yüzde 0,8’ini gördüğünü söylüyor.

Bunun en büyük sebeplerini açıklayan Handmer, kimi Hubble müşahedelerinin başkalarından daha uzun sürebildiğini belirtti. Bunun yanı sıra, kimi ilgi cazibeli alanlar üzerinden tekrarlanan müşahedeler de yapılıyor. Lakin tahminen de en değerli etken, NASA’nın Hubble’ı tüm gökyüzünü haritalayacak halde tasarlamamış olması. Hubble, makul yerlerin anlık imajlarını yakalamak için tasarlandı.

Lakin emeli gökyüzünü haritalamak olmasa da, Hubble’ın 32 yılda yaptığı çekimlerin bir ortaya getirilmesinin katiyen etkileyici bir manzara olduğunu rahatlıkla söyleyebiliriz.

Jaw-dropping image combines 32 years of Hubble telescope photos into one

Jaw-dropping image combines 32 years of Hubble telescope photos into one

NASA recently celebrated 32 years of Hubble observations. The space telescope was launched back in 1990. Since its launch, it has managed to complete over 1.4 million observations. Now, a physicist named Casey Handmer has combined all of those observations into one breathtaking image. This is what all 1.4 million Hubble observations look like together Handler shared the image on Twitter back in…

Casey Handmer makes perhaps the best argument for why the SLS program should be cancelled.

The difference between Casey Handmer and Elon Musk

After reading Casey Handmer's book about building a self-sufficient colony on Mars, and watching Everyday Astronaut's recent 3 part interview with Elon Musk at Starbase, I realize that both of them think similarly. They have a good foundation in physics, chemistry, and other subjects relevant to rocket science. Most of their calculations don't require a PhD in these areas to understand - most of it could be done on a napkin. But when Musk makes these calculations, he moves mountains; when Casey does, and takes the time to write them into a book, very few people take notice.

What I've come to realize is that the ability to make change through just the calculations you make in your head is a great privilege. Call it power, clout, leverage, whatever you like. But having this ability - to effect change in the physical world using only the words that you speak - is a massive superpower. It's the reason why Musk is so effective as a CEO. Because so few of the people who are capable of reasoning about things independently and from first principles are in the position to command others based on that knowledge.

This is not an argument that all decision makers should be scientists. That would be a disaster, because scientists tend to be severely lacking in practical skills such as communication, persuasion, EQ - all weaknesses that Elon *doesn't* have. Ironically, that Elon doesn't have these weaknesses, and is generally capable as an entrepreneur, may in fact be his greatest strength, which allows him to come to power, which in turn allows his technical expertise, formidable but not world-class, to produce actual change.

Knowledge is power, yes, but let us not forget that power is power (hat tip to Cersei). There is beauty is an austere pursuit of pure, academic knowledge, but pure knowledge is useless to those who want to create positive change.

The SpaceX Starship is a very big deal + Countering Misconceptions in Space Journalism

The SpaceX Starship is a very big deal, and Countering Misconceptions in Space Journalism, by Dr. Casey Handmer RSVP and Information: https://conta.cc/361vdvc (For posting only, not for ticket sale on this webpage. Please check RSVP and information link/button for RSVP/registration/tickets. Thank you very much !) The SpaceX Starship is a very big deal and Countering Misconceptions in Space Journalism September 11, 2021, 10 AM PDT (An AIAA Zoom Webinar) by Dr. Casey Handmer Physicist (PhD Caltech) and Software Engineer SpaceX has been working on some variant of the Big Falcon Rocket for almost a decade, with a publicly announced architecture for three years. The target performance figures are on the Starship website, endlessly dissected on Twitter, Reddit, and NASA spaceflight forums, and there’s even a livestream of construction. Yet none of the oft-published mainstream articles seem to capture the magnitude of the vision that Starship embodies. Starship prompts superlatives, but by the end of this presentation the attendees will understand not only how big Starship is, but also that it’s as small as it can possibly be. In addition, the speaker will address the persistence of a variety of common misconceptions in space journalism, and how he decided to write a series of blogs on each topic, the better to understand the issues myself and to function as a handy reference for others. Each blog represents the speaker's opinion only, but will be accessible to a general audience and rigorous enough to adequately support that particular viewpoint. --------------------------------------------------------- Dr. Casey Handmer is a physicist (PhD Caltech) and software engineer who disposes of his copious free time by writing about the industrialization of Mars.

This is a neat exploration of what the plot of Andy Weir's novel/film The Martian would look like if its mission was built on SpaceX's Starship architecture. It's a very different story, and the problems are much different.

It makes me want to write a version of KSR's Red Mars that is based around this model.

The future of electricity is local – Casey Handmer's blog

Don’t hold your breath for the moon

In the house in which I grew up, a single framed newspaper front page loomed over us. “MAN ON MOON“, it declared jubilantly, in an enormous, suitably momentous typeface. Subheadings included “‘It’s very pretty up here … a fine, soft surface’” and, of course, “A giant leap for mankind.”

One leap forward, three steps back. That newspaper was dated fifty years ago today, as I type this. Apollo 17 — “the most recent time humans have travelled beyond low Earth orbit” — took place in December 1972, a date at which a large majority of humanity today was not yet born.

Space travel is not the stuff of science fiction. It is the stuff of history books, of yesteryear, of scratchy black-and-white TV, of that yellowing newspaper cover of my youth.

What happened? I mean, lots, but ultimately the costs were too high, the tangible benefits too nonexistent, and the Space Shuttle was too much of an unmitigated disaster from start to finish in every way.

What happens next? Well, there we have a quick answer: we’re going back! America is going to land the first woman on the moon by 2024! Absolutely!

…you’re absolutely right to be very skeptical.

There are a numerous “lunar exploration architectures,” or ways to return to the Moon. My friend Casey Handmer, a physicist, space enthusiast, and former levitation engineer, itemizes them in this excellent blog post from a few months ago. One of them is NASA’s proposed Lunar Gateway, which will place a space station into high Moon orbit, from and to which lunar landings will descent and return.

Is this a good idea? …Well, it’s an idea. But it’s better to have a plan and to be making progress on it that not, right? Right? …Except the last few months have seen a bewildering flurry of chaos and confusion which makes NASA’s lunar program more closely resemble a headless chicken than a smoothly oiled machine.

First, an unsigned five-page document, riddled with spectacular grammar and spelling errors such as

There is no feasible means to redesign it or any other heavy left rocket to more transport the lunar landing elements

(!) was shared by “the Gateway program office at Johnson Space Center in Houston,” reported Ars Technica. (Casey wrote an exegesis of this dubious document, if you want to see it deconstructed in detail.) Then, earlier this month, NASA demoted and replaced its executives in charge of human space exploration.

Does this sound like the behavior of a lunar project accelerating to an on-target, on-time landing? Or more like a bureaucratic catastrophe thrashing frantically while failing to get anywhere at all? “As it stands, few experts believe NASA’s plan for returning to the moon in 2024 is feasible,” says Vox mordantly. You don’t say.

I’d be so delighted to see a woman walk on the moon in 2024. But I’m not exactly holding my breath. By 2032 we will have gone sixty years, three generations, between human lunar excursions. Some people think we shouldn’t go back at all, that there is too much of more importance to do here on Earth. I disagree, strongly, but I think even they might still agree that it would be sad beyond belief if, if and when we next land on the Moon, there’s no one around who remembers the last time.
