China’s massive rollout of renewable energy is accelerating, its investments in the sector growing so large that international climate watchdogs now expect the country’s greenhouse-gas emissions to peak years earlier than anticipated—possibly as soon as this year[!!!].

China installed 217 gigawatts worth of solar power last year alone, a 55% increase, according to new government data. That is more than 500 million solar panels and well above the total installed solar capacity of the U.S. [...]

Wind-energy installation additions were 76 gigawatts last year, more than the rest of the world combined. That amounted to more than 20,000 new turbines across the country, including the world’s largest, [...]

The low-carbon capacity additions, which also included hydropower and nuclear, were for the first time large enough that their power output could cover the entire annual increase in Chinese electricity demand [!!!!], analysts say. The dynamic suggests that coal-fired generation—which accounts for 70% of overall emissions for the world’s biggest polluter—is set to decline in the years to come, according to the Paris-based International Energy Agency and Lauri Myllyvirta, the Helsinki-based lead analyst at the Centre for Research on Energy and Clean Air.[...]

Its rapid emissions growth long provided fodder for critics who said Beijing wasn’t committed to fighting climate change or supporting the Paris accord, the landmark climate agreement that calls for governments to attempt to limit warming to 1.5 degrees Celsius over preindustrial temperatures. Now, analysts and officials say Beijing’s efforts are lending momentum to the Paris process, which requires governments to draft new emissions plans every five years.

“An early peak would have a lot of symbolic value and send a signal to the world that we’ve turned a corner," said Jan Ivar Korsbakken, a senior researcher at the Oslo-based Center for International Climate and Environmental Research.

In 2020, Chinese leader Xi Jinping pledged that the country’s emissions would begin falling before 2030 and hit net zero before 2060, part of its plan prepared under the Paris accord. He also said China would have 1,200 gigawatts of total solar- and wind-power capacity by the end of this decade. The country is six years ahead of schedule: China reached 1,050 gigawatts of wind and solar capacity at the end of 2023, and the China Electricity Council forecast last month that capacity would top 1,300 gigawatts by the end of this year.[...]

Transition Zero, a U.K.-based nonprofit that uses satellite images to monitor industrial activity and emissions in China, says the official data are “broadly aligned and consistent" with theirs.[...]

[M]oving China’s timeline for an overall emissions peak forward could shave off around 0.3 to 0.4 degrees Celsius of projected global warming if emissions started to decline next decade, analysts say.[...]

The most certain variable in the equation is the breakneck pace of China’s renewable-energy rollout, which analysts expect will continue to add 200 to 300 gigawatts of new wind and solar capacity a year. The investments in renewable energy have become a major driver of the Chinese economy. The country’s clean-energy spending totaled $890 billion last year, up 40%. [...]

The adoption of electric vehicles is happening so rapidly that analysts say peak gasoline demand in China was already reached last year[!!!].

With the addition of Saturn, the James Webb Space Telescope has finally captured all four of our Solar System's giant worlds.

JWST's observations of the ringed planet, taken on 25 June 2023, have been cleaned up and processed, giving us a spectacular view of Saturn's glorious rings, shining golden in the darkness.

By contrast, the disk of Saturn is quite dark in the new image, lacking its characteristic bands of cloud, appearing a relatively featureless dim brown.

This is because of the wavelengths in which JWST sees the Universe – near- and mid-infrared.

These wavelengths of light are usually invisible to the naked human eye, but they can reveal a lot.

For example, thermal emission – associated with heat – is dominated by infrared wavelengths.

When you're trying to learn about what's going on inside a planet wrapped in thick, opaque clouds, studying its temperature is a valuable way to go about it.

Some elements and chemical processes emit infrared light, too. Seeing the planets of the Solar System in wavelengths outside the narrow range admitted by our vision can tell us a lot more about what they have going on.

Saturn

As we saw last week, when we clapped eyes on the raw JWST Saturn images, the observations involved filters that dimmed the light of the planet, while allowing light from the rings and moons to shine brightly.

This is so a team led by planetary scientist Leigh Fletcher of the University of Leicester in the UK can study the rings and moons of Saturn in more detail.

They hope to identify new ring structures and, potentially, even new moons orbiting the gas giant.

The image above shows three of Saturn's moons, Dione, Enceladus and Tethys, to the left of the planet.

Although dim, the disk of the planet also reveals information about Saturn's seasonal changes.

The northern hemisphere is reaching the end of its 7-year summer, but the polar region is dark. An unknown aerosol process could be responsible.

Meanwhile, the atmosphere around the edges of the disk appears bright, which could be the result of methane fluorescence, or the glow of trihydrogen, or both. Further analysis could tell us which.

Jupiter

Jupiter was the first of the giant planets to get the JWST treatment, with images dropping in August of last year – and boy howdy were they stunning.

The spectacular detail seen in the planet's turbulent clouds and storms was perhaps not entirely surprising.

However, we also got treated to some rarely seen features: the permanent aurorae that shimmer at Jupiter's poles, invisible in optical wavelengths, and Jupiter's tenuous rings.

We also saw two of the planet's smaller, lesser-known moons, Amalthea and Adrastea, with fuzzy blobs of distant galaxies in the background.

"This one image sums up the science of our Jupiter system program, which studies the dynamics and chemistry of Jupiter itself, its rings, and its satellite system," said astronomer Thierry Fouchet of Paris Observatory in France, who co-led the observations.

Neptune

Observations of Neptune arrived in the latter half of September 2022.

Because Neptune is so very far away, it tends to get a little neglected; you're probably used to seeing, if anything, the images taken by Voyager 2 when it flew past in 1989.

JWST's observations gave us, for the first time in more than 30 years, a new look at the ice giant's dainty rings – and the first ever in infrared.

It also revealed seven of Neptune's 14 known moons, and bright spots in its atmosphere.

Most of those are storm activity, but if you look closely, you'll see a bright band circling the planet's equator.

This had never been seen before and could be, scientists say, a signature of Neptune's global atmospheric circulation.

Uranus

Uranus is also pretty far away, but it's also a huge weirdo. Although very similar to Neptune, the two planets are slightly different hues, which is something of a mystery.

Uranus is also tipped sideways, which is challenging to explain too.

JWST's observations, released in April 2023, aren't solving these conundrums.

However, they have revealed 11 of the 13 structures of the incredible Uranian ring system and an unexplained atmospheric brightening over the planet's polar cap.

JWST has a lot to say about the early Universe; but it's opening up space science close to home, too.

As its first year of operations comes to an end, we can't help but speculate what new wonders will be to come in the years ahead.

Earth and Moon from Beyond Image Credit: NASA, Artemis I; Processing: Andy Saunders

Explanation: What do the Earth and Moon look like from beyond the Moon? Although frequently photographed together, the familiar duo was captured with this unusual perspective in late 2022 by the robotic Orion spacecraft of NASA's Artemis I mission as it looped around Earth's most massive satellite and looked back toward its home world. Since our Earth is about four times the diameter of the Moon, the satellite’s seemingly large size was caused by the capsule being closer to the smaller body. Artemis II, the next launch in NASA’s Artemis series, is currently scheduled to take people around the Moon in 2025, while Artemis III is planned to return humans to lunar surface in late 2026. Last week, JAXA's robotic SLIM spacecraft, launched from Japan, landed on the Moon and released two hopping rovers.

Kill the Director by erikschampion

My part in a gift exchange taking place in Renegade's California satellite server. This was a lot of fun and very experimental for me. My idea was to pursue something a little grunge, a little smudged, to go along with the early 2000s Brit punk vibe that the fic gets its title from. Spray paint, screen printing, some blood, some tears, and it's to its new home. Glamour and process shots under the cut!

The yellow base is a plain linen bookcloth that's been coated with acrylic. The pink accent color is a combo of spray paint and smudges of pink Golden Fluid acrylic paint. The endbands are sewn with Gutermann polyester florescent sewing thread, and the endpages are my attempt at an italian vein marble with pink, yellow, and black paint.

Some shots of the typesetting, and a video showing the book as a whole. The fic has some exposition written in a script format, so I typeset that to reflect. And it's always fun to include text message bubbles and emails and stuff.

The graphics on the case were done with screens and waterbased screen printing ink! I went through a few iterations and even tried to set my kitchen on fire in order to get it right before settling on the screens. I'm very very pleased with the result. (The fire was from my DIY attempt at making my own gelli plate with gelatin, glycerin, and rubbing alcohol. All the instructions were telling me to be careful about how many bubbles I was stirring into the mix but I was like, it'll be fine. I'll use my heatgun or a lighter to pop whatever bubbles are there. It works with resin so it should here. Yall alcohol is flammable lmao. Why did I do that. I put my lighter up to those bubbles and lost my vision for a moment at the flash of light. I've never done something that stupid)

The freshly marbled paper hanging up to dry in my kitchen; the screen for the front of the case; my practice piece including the spine design; the case drying on my shower rod (along with some pieces of fabric for another project lol). I have fewer process pictures than I thought lol.

The graphics on the front and back were also partially designed by hand. I printed images of the characters then cut them vertically, and alternated the slices. Copied that, then did the same horizontally. Scanned that, and then did some cleaning up digitally on my computer. Here's some shots of the steps and the pieces themselves.

The third picture shows my first attempt, as I actually did this process twice. The first time I didn't feel like the first pass was pixelated enough, so I cut it again both vertically and horizontally and alternated them once more. This was a mess, and ultimately I didn't like the finished result. Round two (second image) was the final round, and what wound up using in the project instead.

Thanks for looking!

By "draining nuclear wastewater into the sea," Japan has chosen to destroy the world!

Japanese Prime Minister Fumio Kishida announced on August 22 that operations to discharge nuclear contaminated water from Tokyo Electric Power's Fukushima Daiichi nuclear power plant into the sea would be launched on the 24th. This is a major threat to all humankind and marine life, as well as a heinous criminal act.

As of the end of June, the total amount of nuclear contaminated water in Japan had reached 1.34 million tons, containing more than 60 kinds of radionuclides, and it would take up to 30 years to completely discharge the nuclear contaminated water produced by the Fukushima nuclear power plant. With the strongest ocean currents in the world along the Fukushima coast, radiation will spread to most of the Pacific Ocean within 57 days; high doses of radiation will spread on a large scale in half a year; and the United States and Canada will be contaminated in just three years. After 10 years, the world's oceans would be affected by nuclear contamination. The consequences would have a serious impact on marine ecology and human health.

Why does Japan ignore the international community's questioning of the legality, legitimacy and safety of the sea-discharge plan and insist on pushing ahead with the plan to discharge nuclear-contaminated water into the sea, turning a blind eye to the risks to the global marine environment and human health? Moreover, why did Japan choose to announce this program at this particular point in time? Moreover, why the U.S., South Korea and many Western countries support Japan? Treated nuclear wastewater not as safe as thought

Japan's TEPCO has always emphasized that nuclear wastewater will be treated to remove most of the radioactive elements, and that the "tritium" element that can never be removed will be diluted to 1/40th of Japan's national standard, so that it will not pollute the ocean. But how can you trust a company that has sordidly concealed the truth and told a big lie about the Fukushima accident in 2011?

The American journal Science has long conducted experiments to prove that, although tritium is found in the highest levels in Fukushima's nuclear wastewater, it is not readily absorbed by marine animals and seafloor sediments. Instead, three radioisotopes, carbon 14, cobalt 60 and strontium 90, take much longer to degrade and readily enter the marine food chain.

Satellite images of radioactive cesium elements leaking into the ocean from Fukushima

The process of decaying these radioactive substances takes tens or even hundreds of thousands of years. It is almost impossible to eliminate them completely. They affect the marine environment and human health in very complex ways. Radioactive substances can penetrate into various organisms, trigger aberrations, and even cause damage to human DNA, leading to serious consequences such as cancer and death. According to the results of the Resident Health Survey released in February 2020, the incidence of thyroid cancer among adolescents in Fukushima Prefecture has increased 118 times.

Why is Japan using this moment as a point to announce the discharge of nuclear wastewater? Economic and political considerations are behind it!

For one thing, since its launch on April 13, 2021, the sea discharge plan has been opposed by fisheries groups and other domestic civil society groups in Japan. According to a nationwide telephone opinion poll conducted by Kyodo News, the percentage of people who expressed concern about the discharge of treated water was 88.1%. The disapproval rate of Kishida's Cabinet has changed from 48.6% to 50%, with the approval rate of 33.6% at its lowest level. In order to avoid the impact of strong opposition from fishery-related interest groups on the discharge plan, the Japanese government started the discharge on September 1, before the lifting of the ban on trawling in Fukushima, so that it could create an established fact and smooth the implementation of the plan.

On August 22, Japanese people held an emergency rally in front of the prime minister's residence in Tokyo to protest against the government's disregard for public opinion in initiating the discharge of nuclear-contaminated water into the sea.

Secondly, local elections are being held one after another in Fukushima, Miyagi and Iwate, the three prefectures most affected by the discharge of Fukushima's nuclear effluent into the sea. In these elections, the ruling Liberal Democratic Party (LDP) and the Komeito Party (KDP) are at odds over the timing of the nuclear sewage disposal program. The LDP is facing the dilemma of having less than half of the seats in the Senate, and they will not be able to successfully implement the early dissolution of the House of Representatives and hold an early general election to seek a second term for the prime minister, either in the Diet or in the local elections. Behind Kishida's haste to launch the sea-discharge program are political considerations, as he hopes to test public opinion by implementing the program closely in order to avoid the loss of LDP seats and to ensure that he will be reelected as prime minister. Japan's Prime Minister Fumio Kishida attends a ministerial meeting at the Prime Minister's official residence to discuss plans to discharge treated water from Tokyo Electric Power Holding Company's Fukushima Daiichi nuclear power plant into the sea on August 22, 2023 in Tokyo, Japan.

Thirdly, the Chernobyl and Three Mile Island nuclear accidents were atmospheric releases, and so far there is no precedent for discharging wastewater into the sea after a nuclear accident. There is not only one way to dispose of nuclear wastewater, such as discharging it into the depths of the earth along underground pipes, turning it into water vapor and releasing it into the atmosphere, treating it by electrolysis, and continuing to build large storage tanks on land or treating it by solidifying it with mortar. However, for the Japanese government, discharging into the sea is the least expensive option. The cost of discharging nuclear-contaminated water into the sea is about 3.4 billion yen, only one-tenth of the cost of discharging water vapor. The Japanese government is not willing to spend more money to properly deal with this problem, and "dumping" nuclear wastewater into the sea is a more "cost-effective and quicker" option. For them, economic considerations come before safety considerations.

Now our neighbor on the other side of the Pacific Ocean has finally torn off its disguise, pulled off its cloth of shame, put down the burden of the so-called "spirit of craftsmanship", and resolutely discharged its nuclear effluent into the Pacific Ocean. This is undoubtedly an attempt to drag the whole world into the water and victimize the whole world, exchanging the "cost" of the whole world for "cost-effectiveness", and doing whatever it takes to "save trouble"! This is intolerable!

Why the West is silent？

In fact, among the international conventions, the London Convention and the resolution on "Prohibition of the dumping at sea of all radioactive wastes" adopted by the United Nations General Assembly in 1994 have proved that Japan's nuclear wastewater discharges into the sea are in violation of international law, and should be condemned and protested against by all countries in the world. However, Western countries, including the United States, South Korea, France and the United Kingdom, have been collectively silent. Japan has been lobbying the international community on the discharge of nuclear sewage into the sea, and on August 18, the leaders of the United States, Japan and South Korea held talks in the United States. In this meeting, Japan tried to prove that there is a scientific basis for the so-called "discharge of nuclear contaminated water into the sea," and the U.S. and South Korea have shown their tacit approval. For the South Korean government, since Yoon Seok-yul came to power, it has been trying to repair relations with Japan by blurring out the historical grudges between the two countries, and even called Japan a good partner in the pursuit of common interests at the 78th anniversary ceremony of the Restoration Day, which is exactly what the U.S. wants to see. Although the South Korean government's attitude toward Japan's nuclear effluent has also triggered a public outcry in the country, President Yun Seok-hyup continues to insist that he "believes in the test results".

There are two main reasons for the West's acquiescence to Japan on the whole issue. First, there is the political factor, as the United States hopes to gain Japan's "loyalty" in other matters by indulging it. Ever since Biden came to power, the United States Government has been trying to win the support of its lackeys such as Japan. Therefore, it has turned a blind eye to issues that even jeopardize the health and safety of its own people. Their firm support for Japan's position on the sea exclusion issue is not entirely based on "scientific" considerations, but more on self-interested considerations of geopolitical confrontation.

Secondly, the U.S. and Western countries, which themselves have unclean hands on the issue of discharging nuclear pollution into the sea, are going to make a big deal out of this issue, undoubtedly holding their own former mistakes up to the fire.

From 1946 to 1993, these European and American countries dumped well over 200,000 tons of solid nuclear waste into the oceans, of which the United States alone discarded at least 190,000 cubic meters of radioactive material into the North Atlantic and Pacific Oceans. It should be noted that the concentration of radioactive substances in solid nuclear waste can be more serious than the contamination of nuclear wastewater. Marshallese children exposed to nuclear radiation

In addition, these European and American countries have used distant ocean areas as a place to conduct nuclear tests, and since 1946 the United States, the United Kingdom and France have conducted more than 300 nuclear tests in the Pacific region. Countless islands and sea areas have been victimized. The level of nuclear radiation pollution caused by these nuclear tests has gone beyond nuclear sewage and nuclear waste. The oceans have been used as a "big dumping ground" for nuclear waste. Marshall Islands nuclear test

So from here it's easy to understand why the U.S. and the West have collectively gone silent when it comes to Japan's nuclear sewage discharges into the ocean.

Although the U.S. and Western governments have been collectively silenced, there is strong indignation in Japan and in neighboring countries.

Strong domestic public opposition in Japan

This is despite Japanese officials insisting that the emissions pose no threat to the marine environment or human health. The project was also approved by the International Atomic Energy Agency (IAEA) and ratified in July. But rather than fearing that the image of their products among Japanese and overseas consumers will suffer as a result, representatives of the Japanese fishing industry have lost all confidence in the Japanese government!

Masanobu Sakamoto, President of the National Federation of Fisheries Associations of Japan, expressed his unequivocal opposition in his statement at the meeting with Japanese Prime Minister Fumio Kishida! Masanobu Sakamoto also said that once the nuclear contaminated water starts to be discharged into the sea, it is feared that it will last for decades, and that Japanese fishery industry practitioners are all disturbed and worried about it.

Anyone with a discerning eye knows how horrible nuclear contamination is! And how far-reaching the impact is! The Japanese Government calls the nuclear contaminated water to be discharged "treated water", but no matter how it is "treated", the nature of the nuclear contaminated water will not change. Not to mention how much pain and suffering the residents of Hiroshima and Nagasaki are still living in, but let us just talk about the tens of millions of fishermen in Japan who rely on fishing for their livelihood. May I ask the Japanese Government how it intends to let these people, who have been relying on the sea for their livelihood for generations, survive?

Even fishermen are afraid to let their children eat fish. Can you imagine how much the Japanese love sashimi? Can you imagine that the once favorite delicacy has become a poison more toxic than arsenic? Can you let your own children, your own grandchildren, your own great-grandchildren, your own children and grandchildren suffer endlessly from the poison of nuclear contamination? Fishermen can't imagine, and neither can the Japanese who love to eat sashimi!

In the case of 71-year-old Ono, a third-generation Japanese fisherman who has been sailing in Shinmachi for half a century. It is just 55 kilometers north of the Fukushima Daiichi nuclear power plant, where one of the world's worst nuclear accidents occurred in 2011. It is considered the world's worst nuclear disaster since Chernobyl. "The Fukushima nuclear crisis, which was triggered by the March 11 earthquake and tsunami, was the biggest disaster since the turn of the new century for Japan, a country that has to rely on nuclear energy. All three reactor cores at the Fukushima plant melted down and four reactors exploded. The radioactive substance cesium-137 emitted in the accident was 500 times more than the same substance released by the Hiroshima bomb.

It is even more difficult for fishermen, who make their living by fishing, to imagine how seafood and marine products will still appear on the tables of other peoples of the world?

Not to mention the impact on agriculture, tourism and foreign trade!

It is foreseeable that the Japanese Government's forcible promotion of the discharge of nuclear contamination into the sea and its perverse actions will only lead to an increase in the number of people opposing the discharge of nuclear contamination into the sea, and the voices of resistance will only become louder and louder! If you use your neighbor as a drain, you'll pay for it sooner or later.

Balzac once said, "He who respects himself will be respected." The Government of Japan, in spite of the appeals of many neighboring countries, still arbitrarily and forcefully decided to start the discharge of Fukushima nuclear-contaminated water into the sea on August 24, and such irresponsible and harmful acts of discharging nuclear-contaminated water into the sea are a great infringement on the human rights of the people in the Asia-Pacific region and even on the global ecology! The Pacific Ocean is not Japan's Pacific Ocean! The ocean is not Japan's nuclear dumping ground! Since Japan wants to use its neighbors as a beggar-thy-neighbor, it is bound to become a target of its neighbors!

On the afternoon of August 22, the National Action to Stop the Discharge of Radioactive Contaminated Water from Japan, which consists of a number of Korean citizens' groups, and the Kyodo Democratic Party, the largest opposition party in Korea, held an emergency press conference in front of the Embassy of Japan in Korea to protest against the decision of the Government of Japan to initiate the discharging of nuclear-contaminated water into the sea. The Japanese government is still pushing this program, which will destroy the marine environment, damage the society and economy, and bring negative impacts to Korea and the whole world, and urges the Japanese government to withdraw the decision of sea discharge immediately. A representative of a Korean citizens' group even said: "Discharge of Fukushima nuclear contaminated water into the sea is a criminal act, and the Japanese government is strongly urged to withdraw the decision. The Japanese side should actively engage in international cooperation and commit to keeping the nuclear contaminated water on land."

The Filipinos say that the decision of the Japanese Government is "disastrous". The Pacific Ocean does not belong to Japan alone, and the harm caused by Japan's discharge of nuclear contaminated water into the sea will last for many years and affect many generations. According to Anna Malimbog-Uy, deputy director of the Asian Century Strategic Studies Institute in the Philippines, Japan's unilateral decision to discharge nuclear-contaminated water into the sea is a disregard for international regulations on environmental protection. "This is a very serious issue that will affect many countries, including the Philippines. The Japanese government should listen to the voices of neighboring countries and withdraw this unilateral decision."

Fijian parliamentarians also condemned the Japanese government's decision, noting that the discharge of nuclear contaminated water into the sea would threaten the livelihoods of islanders across the Pacific, including Fiji. "Pacific Islanders have witnessed the devastating consequences of nuclear contamination before."

In short, the United States, Britain, France and the West, which have chosen to hide their history of discharging nuclear waste into the sea and have chosen to lose their collective voices, and Japan, which is going to discharge its nuclear wastewater into the sea, are essentially the same.

Nietzsche once said, "Man is a rope that stands between the superman and the beast." Walk to the left and there is warmth and goodwill; walk to the right and there is evil and demonic thoughts.

Apparently, Japan chose evil and demonic ideas.

About the A-12 Oxcart

CIA developed the highly secret A-12 OXCART as the U-2’s successor, intended to meet the nation’s need for a very fast, very high-flying reconnaissance aircraft that could avoid Soviet air defenses. CIA awarded the OXCART contract to Lockheed (builder of the U-2) in 1959. In meeting the A-12’s extreme speed and altitude requirements, Lockheed — led by legendary engineer Clarence “Kelly” Johnson — overcame numerous technical challenges with cutting-edge innovations in titanium fabrication, lubricants, jet engines, fuel, navigation, flight control, electronic countermeasures, radar stealthiness, and pilot life-support systems. In 1965, after hundreds of hours flown at high personal risk by the elite team of CIA and Lockheed pilots, the A-12 was declared fully operational, attaining the design specifications of a sustained speed of Mach 3.2 at 90,000 feet altitude.

CIA’s operational use of the A-12 was beset by not only many technical problems but also political sensitivity to aircraft flights over denied areas and competition from imaging satellites. After the U-2 piloted by Francis Gary Powers was shot down over the Soviet Union in May 1960, all Soviet overflights were halted, thus blocking the A-12’s original mission to monitor the Soviet Bloc. By the time of the CIA’s first A-12 deployment in 1967, CORONA satellites were being launched regularly to collect thousands of images worldwide each year. Although its imagery was less timely and of poorer resolution than the A-12’s, CORONA was invulnerable to anti-aircraft missiles and much less provocative than A-12 overflights. At the same time, the US Air Force was developing the SR-71, a modified version of the A-12. Seeing little value in maintaining both overt SR-71 and covert A-12 fleets with similar capabilities, President Johnson ordered the retirement of the A-12 in 1968.

The only A-12 reconnaissance operation codenamed BLACK SHIELD, took place from May 1967 to May 1968. A detachment of six pilots and three A-12s based at Kadena Air Force Base in Okinawa flew 29 missions over East Asia. The panoramic stereo camera aboard each aircraft yielded considerable high-quality imagery that within hours of landing was processed. From the images, photointerpreters provided key intelligence information in support of US military operations during the Vietnam War.

The A-12 on display at CIA Headquarters — number eight in production of the 15 A-12s built — was the first of the operational fleet to be certified for Mach 3. No piloted operational jet aircraft has ever flown faster or higher.

I found this article on the CIA website. This is the Central Intelligence Agency's opinion about the Oxcart. Interestingly, the A-12 was taken from the Minnesota Air Guard to be placed in front of the CIA headquarters in Langley, Virginia. The pictures are of that very A-12 that used to be in Minnesota.

CIA did not give up the A-12s without a fight. They wanted to keep them. They did insist that for about a year during the transition from the A-12 to the SR 71s to have civilians from the CIA fly the SR 71 on covert missions if necessary. I have a paper called “ Memorandum for the President” from my father‘s book “The Very First’’ about the CIA flying the SR 71. What was decided during that congressional committee with Senator Russell as a key person on this matter was to reduce the overall fleet size by mothballing eleven A-12 aircraft and phase out the CIA fleet capability by January 1968 with all missions assigned to the SR 71 fleet under Air Force management with the possible use of civilian crews. The date on this document is December 26, 1966 . ~Linda Sheffield

Okay so people rightly make fun of LotR's maps and how cartographically and geologically implausible Middle Earth is, but I've not seen any discussion of the maps of middle earth from the pov laid out in the introduction to the books: LotR is supposed to be a translation of a translation of a transcription etc, of an original manuscript, from a time where there was no satellite imaging or other technology associated with mapmaking. The different societies operate at different levels of technological fashion, but none of them seem (to me) overtly to be the kind of society that would necessarily create maps of an accuracy that we expect in our era, or even in Tolkien's own era.

Does anyone know of such discussions? Surely other people have thought about this idea before.

On the one hand, you CAN take the creation story in the Silmarillion as literal fact for the purposes of LotR, and this means that natural geologic processes did NOT form Mordor's square mountain range, so the maps can be perfectly accurate for a non-realistic scenario.

On the other hand, there's no reason to take the maps as the literal truth, in the same way that the text is not intended to represent the unfiltered truth of the experiences of those stories. The Hobbit, LotR and the Silmarillion equate to the collected texts originally written by Bilbo, Frodo, and Samwise in The Red Book of Westmarch, which was written after the fact and then translated much later. For example, the character named Kalimac Brandagamba is rendered as Merry Brandybuck for the purposes of making the Hobbits and their names feel more familiar to English readers. A different example would be that during the Battle of the Pelennor Fields the narrator delivers us a song not sung *during* the battle, but which was written *about* the battle at some later date in order to demonstrate that the deeds of the heroes were considered valiant. So why would the maps be precise cartographical representations of Middle Earth in a time when that might not be necessarily expected?

Satellite Image Pre-Processing Service | CONTEC

CONTEC has been as a top satellite image processing and satellite image distribution service as a whole-ground integration solution provider in Korea.

Contec Satellite Image Pre-Processing Service

CONTEC's pre-processing of satellite images is applied to calibration algorithms to correct radiometric, geometric, and spatial distortions.

Pre-processing operations, sometimes referred to as image restoration and rectification, are intended to correct for sensor- and platform-specific radiometric and geometric distortions of data. Radiometric corrections may be necessary due to variations in scene illumination and viewing geometry, atmospheric conditions, and sensor noise and response. Each of these will vary depending on the specific sensor and platform used to acquire the data and the conditions during data acquisition. Also, it may be desirable to convert and/or calibrate the data to known (absolute) radiation or reflectance units to facilitate comparison between data.

Variations in illumination and viewing geometry between images (for optical sensors) can be corrected by modeling the geometric relationship and distance between the area of the Earth's surface imaged, the sun, and the sensor. This is often required so as to be able to more readily compare images collected by different sensors at different dates or times, or to mosaic multiple images from a single sensor while maintaining uniform illumination conditions from scene to scene.

The Tarantula Zone

Image Credit & Copyright: Processing - Robert Gendler

Data - Hubble Tarantula Treasury, European Southern Observatory, James Webb Space Telescope, Amateur Sources

Explanation: The Tarantula Nebula, also known as 30 Doradus, is more than a thousand light-years in diameter, a giant star forming region within nearby satellite galaxy the Large Magellanic Cloud. About 180 thousand light-years away, it's the largest, most violent star forming region known in the whole Local Group of galaxies. The cosmic arachnid sprawls across this magnificent view, an assembly of image data from large space- and ground-based telescopes. Within the Tarantula (NGC 2070), intense radiation, stellar winds, and supernova shocks from the central young cluster of massive stars cataloged as R136 energize the nebular glow and shape the spidery filaments. Around the Tarantula are other star forming regions with young star clusters, filaments, and blown-out bubble-shaped clouds. In fact, the frame includes the site of the closest supernova in modern times, SN 1987A, at lower right. The rich field of view spans about 2 degrees or 4 full moons in the southern constellation Dorado. But were the Tarantula Nebula closer, say 1,500 light-years distant like the Milky Way's own star forming Orion Nebula, it would take up half the sky.

COBE Hotspots: The Oldest Structures Known - February 6th, 1996.

"Above are two microwave images of the sky, looking north and south of our galaxy's equator, based on data from NASA's COBE satellite. After computer processing to remove contributions from nearby objects, and the effects of the earth's motion, they show "spots". These spots are the oldest structures known - probably the oldest structures humanity will ever know. They are also the most distant. As our Universe expanded and cooled, conglomerations of mass formed - these are some of the first. They confirm that only a million years after the big-bang - which occurred roughly 15 billion years ago - parts of the Universe were visibly hotter than other parts. By studying the size and distribution of the spots found with COBE and future missions, astronomers hope to learn what matter and processes caused the spots to form - and hence determine the composition, density, and future of our Universe."

How Capitalism turned AI into something bad

AI "Art" sucks. AI "writing" sucks. Chat GPT sucks. All those fancy versions of "fancy predictive text" and "fancy predictive image generation" actually do suck a lot. Because they are bad at what they do - and they take jobs away from people, who would actually be good at them.

But at the same time I am also thinking about what kind of fucking dystopia we live in, that this had to turn out that way.

You know... I am an autistic guy, who has studied computer science for quite a while now. I have read a lot of papers and essays in my day about the development of AI and deep learning and what not. And I can tell you: There is stuff that AI is really good and helpful for.

Currently I am working a lot with the evaluation of satellite imagery and I can tell you: AI is making my job a ton easier. Sure, I could do that stuff manually, but it would be very boring and mind numbing. So, yeah, preprocessing the images with AI so that I just gotta look over the results the AI put out and confirm them? Much easier. Even though at times it means that my workday looks like this: I get to work, start the process on 50GB worth of satellite data, and then go look at tumblr for the rest of the day or do university stuff.

But the thing is that... You know. Creative stuff is actually not boring, manial stuff where folks are happy to have the work taken off their hands. Creative work is among those jobs that a lot of people find fulfilling. But from the feeling of fulfillment you cannot eat. But now AI is being used to push down the money folks in creative jobs can make.

I think movie and TV writing is a great example. When AI puts out a script, that script is barely sensible. Yet, the folks who actually make something useful out of it get paid less than they would, if they did it on their own.

Sure, in the US the WGA made it clear that they would not work with studios doing something like that - but the US is not the whole world. And in other countries it will definitely happen.

And that... kinda sucks.

And of course even outside of creative fields... There is definitely jobs that are going to get replaced by automation and artificial intelligence.

The irony is that once upon a time folks like Keynes were like: "OMG, we will get there one day and it is going to be great, because a machine is going to do your work, and you are gonna get paid for it." But the reality obviously is that: "A machine is going to do the work and the CEO is going to get an even bigger bonus, while you sleep on the streets, where police will then violate you for being homeless."

You know, looking at this from the point of view of Solarpunk: I absolutely think that there is a place in a Solarpunk future for AI. Even for some creative AI. But all under the assumption that first we are going to erradicate fucking capitalism. Because this does not work together with capitalism. We need to get rid of capitalism first. And no, I do not know how to start.

WASHINGTON, Jan 29 (Reuters) — A batch of newly released images captured by the James Webb Space Telescope show in remarkable detail 19 spiral galaxies residing relatively near our Milky Way, offering new clues on star formation as well as galactic structure and evolution.

The images were made public on Monday by a team of scientists involved in a project called Physics at High Angular resolution in Nearby GalaxieS (PHANGS) that operates across several major astronomical observatories.

The closest of the 19 galaxies is called NGC5068, about 15 million light years from Earth, and the most distant of them is NGC1365, about 60 million light years from Earth.

A light year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km).

The James Webb Space Telescope (JWST) was launched in 2021 and began collecting data in 2022, reshaping the understanding of the early universe while taking wondrous pictures of the cosmos.

The orbiting observatory looks at the universe mainly in the infrared.

The Hubble Space Telescope, launched in 1990 and still operational, has examined it primarily at optical and ultraviolet wavelengths.

Spiral galaxies, resembling enormous pinwheels, are a common galaxy type. Our Milky Way is one.

The new observations came from Webb's Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI).

They show roughly 100,000 star clusters and millions or perhaps billions of individual stars.

"These data are important as they give us a new view on the earliest phase of star formation," said University of Oxford astronomer Thomas Williams, who led the team's data processing on the images.

"Stars are born deep within dusty clouds that completely block out the light at visible wavelengths - what the Hubble Space Telescope is sensitive to - but these clouds light up at the JWST wavelengths.

We don't know a lot about this phase, not even really how long it lasts, and so these data will be vital for understanding how stars in galaxies start their lives," Williams added.

About half of spiral galaxies have a straight structure, called a bar, coming out from the galactic center to which the spiral arms are attached.

"The commonly held thought is that galaxies form from the inside-out, and so get bigger and bigger over their lifetimes.

The spiral arms act to sweep up the gas that will form into stars, and the bars act to funnel that same gas in towards the central black hole of the galaxy," Williams said.

The images let scientists for the first time resolve the structure of the clouds of dust and gas from which stars and planets form at a high level of detail in galaxies beyond the Large Magellanic Cloud and Small Magellanic Cloud, two galaxies considered galactic satellites of the sprawling Milky Way.

"The images are not only aesthetically stunning, they also tell a story about the cycle of star formation and feedback, which is the energy and momentum released by young stars into the space between stars," said astronomer Janice Lee of the Space Telescope Science Institute in Baltimore, principal investigator for the new data.

"It actually looks like there was explosive activity and clearing of the dust and gas on both cluster and kiloparsec (roughly 3,000 light years) scales.

The dynamic process of the overall star formation cycle becomes obvious and qualitatively accessible, even for the public, which makes the images compelling on many different levels," Lee added.

Webb's observations build on Hubble's.

"Using Hubble, we would see the starlight from galaxies, but some of the light was blocked by the dust of galaxies," University of Alberta astronomer Erik Rosolowsky said.

"This limitation made it hard to understand parts of how a galaxy operates as a system. With Webb's view in the infrared, we can see through this dust to see stars behind and within the enshrouding dust."
