No Strange New Respect For Mike Johnson - by Brian Beutler

1 Share

A weekend of important news has quickly overshadowed something striking that led up to it: In just the past few weeks, several House Republicans (none particularly “moderate”) have conceded that their conference is lousy with Russian influence. 

On Thursday, Rep. Dan Crenshaw (R-TX) admitted that Donald Trump’s enforcers in Congress “want Russia to win so badly that they want to oust the speaker over it.”

Reps. Mike Turner (R-OH) and Michael McCaul (R-TX), who chair the House intelligence and foreign affairs committees respectively, have each accused those same Republicans of mainlining Russian propaganda and echoing it on the floor of the House.

So the secret is out.

It’s on one level a penetrating glimpse into the obvious—Republican affinity for Russia and Vladimir Putin has been undisguised and growing since Trump took over the party years ago. On another level it’s satisfying: A pincer movement of MAGA loyalists and left-wing critics of the Democratic Party has spent years mocking liberals over their supposed obsession with Russia, only for a group of somewhat-less-deranged Republicans to admit the truth quite openly.

Hostilities between the two GOP factions boiled over Saturday when the House finally passed legislation that will provide $61 billion in military aid to Ukraine, after MAGA—and its handpicked speaker, Mike Johnson—starved Kyiv for more than half a year on Trump’s orders. In the wake of that development, liberals and Democrats have praised Johnson (some more reluctantly than others) for having an open mind and ultimately doing the right thing, though his speakership was at risk. President Volodymyr Zelensky of Ukraine even singled out Johnson publicly for a note of personal thanks.

I understand the collective sense of relief. But I’m also left feeling like we’ve agreed to conceal the elephant in the room with little more than a knowing nod. Why’d Johnson ultimately abandon the Russia-loyalists in his conference, and does he agree with Crenshaw, McCaul, Turner et al that his old faction is compromised? If so, what does he, as a leader of his party, plan to do about it? Or does he intend to let this big breach in the U.S. government fester for whatever strategic advantage it may provide the Republican Party.

By way of analogy: If you drain your retirement savings to pay off the mob, but win it all back gambling, on one level it’s no harm no foul. On another level it raises some important questions about who you are! 

Obviously getting aid to Ukraine is the most urgent imperative. But at some point soon we should have a conversation about who was doing what since our last tranche of Ukraine aid lapsed months ago, and why they were doing it.

NASA officially greenlights $3.35 billion mission to Saturn’s moon Titan | Ars Technica

1 Share

NASA has formally approved the robotic Dragonfly mission for full development, committing to a revolutionary project to explore Saturn's largest moon with a quadcopter drone.

Agency officials announced the outcome of Dragonfly's confirmation review last week. This review is a checkpoint in the lifetime of most NASA projects and marks the moment when the agency formally commits to the final design, construction, and launch of a space mission. The outcome of each mission's confirmation review typically establishes a budgetary and schedule commitment.

“Dragonfly is a spectacular science mission with broad community interest, and we are excited to take the next steps on this mission," said Nicky Fox, associate administrator of NASA's science mission directorate. "Exploring Titan will push the boundaries of what we can do with rotorcraft outside of Earth.”

In the case of Dragonfly, NASA confirmed the mission with a total lifecycle cost of $3.35 billion and a launch date of July 2028. That is roughly twice the mission's original proposed cost and a delay of more than two years from when the mission was originally selected in 2019, according to NASA.

Busting the cost cap

Rising costs are not necessarily a surprise on a mission as innovative as Dragonfly. After reaching Titan, the eight-bladed rotorcraft lander will soar from place to place on Saturn's hazy moon, exploring environments rich in organic molecules, the building blocks of life.

Dragonfly will be the first mobile robot explorer to land on any other planetary body besides the Moon and Mars, and only the second flying drone to explore another planet. NASA's Ingenuity helicopter on Mars was the first. Dragonfly will be more than 200 times as massive as Ingenuity and will operate six times farther from Earth.

Despite its distant position in the cold outer Solar System, Titan appears to be reminiscent of the ancient Earth. A shroud of orange haze envelops Saturn's largest moon, and Titan's surface is covered with sand dunes and methane lakes.

Titan's frigid temperatures—hovering near minus 290° Fahrenheit (minus 179° Celsius)—mean water ice behaves like bedrock. NASA's Cassini spacecraft, which flew past Titan numerous times before its mission ended in 2017, discovered weather systems on the hazy moon. Observations from Cassini found evidence for hydrocarbon rains and winds that appear to generate waves in Titan's methane lakes.

Clearly, Titan is an exotic world. Most of what scientists know about Titan comes from measurements collected by Cassini and the European Space Agency's Huygens probe, which Cassini released to land on Titan in 2005. Huygens returned the first pictures from Titan's surface, but it only transmitted data for 72 minutes.

Dragonfly will explore Titan for around three years, flying tens of kilometers about once per month to measure the prebiotic chemistry of Titan's surface, study its soupy atmosphere, and search for biosignatures that could be indications of life. The mission will visit more than 30 locations within Titan's equatorial region, according to a presentation by Elizabeth Turtle, Dragonfly's principal investigator at the Johns Hopkins University Applied Physics Laboratory.

"The Dragonfly mission is an incredible opportunity to explore an ocean world in a way that we have never done before,” Turtle said in a statement. “The team is dedicated and enthusiastic about accomplishing this unprecedented investigation of the complex carbon chemistry that exists on the surface of Titan and the innovative technology bringing this first-of-its-kind space mission to life."

However, this high level of ambition comes at a high cost. NASA selected Dragonfly to proceed into initial development in 2019. Turtle's science team proposed Dragonfly to NASA through the agency's New Frontiers program, which has developed a series of medium-class Solar System exploration missions. The New Frontiers program has an impressive pedigree, beginning with the New Horizons mission that flew by Pluto in 2015, the Juno mission to Jupiter, and the OSIRIS-REx asteroid sample return mission.

Dragonfly's lifecycle cost of $3.35 billion will make it significantly more expensive than any of those missions.

When NASA chose Dragonfly in 2019, the mission had a cost cap of $850 million ($1 billion when adjusted for inflation) to get it to the launch pad. The budget limit didn't include the launch or costs to operate the Dragonfly spacecraft after launch. The costs originally under the budget cap have increased the $1 billion post-inflation figure to $2.1 billion, according to NASA.

Since 2019, NASA had to replan the Dragonfly mission multiple times due to funding constraints that limited how much the agency could spend on the project each fiscal year. Managers navigated the challenges imposed by the pandemic and supply chain issues. There was also an "in-depth design iteration," the agency said in a statement.

During this time, NASA directed managers in charge of Dragonfly to delay its launch from 2026 to 2027, which required the mission to change from a medium-lift to a heavy-lift launcher. As a result of this, NASA upped the funding for Dragonfly to pay for a bigger rocket. Dragonfly's updated launch window in July 2028 will still require a high-energy launch, likely on a SpaceX Falcon Heavy or a United Launch Alliance Vulcan rocket. NASA will likely select a launch provider for Dragonfly later this year.

Collectively, these pressures caused Dragonfly's lifecycle cost to grow to $3.35 billion, more in line with a flagship-class interplanetary mission than a cost-capped project. The two most recent New Frontiers missions came in between $1 billion and $1.5 billion, while Europa Clipper, NASA's next flagship planetary science probe, will cost around $5 billion.

NASA's commitment to Dragonfly also comes as the agency faces budget cuts. These reductions have hit the agency's planetary science division particularly hard. NASA is revamping plans for its big planetary flagship mission, Mars Sample Return, to try to rein in growing costs. The agency has postponed a call for scientists to propose concepts for the next New Frontiers mission that will follow Dragonfly.

Despite the higher costs, Dragonfly escaped cancellation. A major reason for this appears to be that NASA's budgetary limitations, and not any mismanagement from within the Dragonfly project, were responsible for a large share of the cost growth.

Assuming a launch in July 2028, Dragonfly will arrive at Titan in December 2034. Cocooned inside a heat shield and aeroshell, Dragonfly will enter Titan's atmosphere and deploy a parachute to slowly descend to the surface over the course of nearly two hours. Then, the quadcopter will settle onto the ground with its fixed landing skids.

At the surface, Titan's atmosphere is four times thicker than Earth's. This makes the process of getting to the ground a lot longer than a lander entering the atmosphere of Earth or Mars, but the higher air density should provide excellent flying conditions.

Not wrong: every cool thing we hear about outcomes is going to be sacrificed on the altar of shareholder value.

“Nurses know that AI technology and algorithms are owned by corporations that are driven by profit — not a desire to improve patient care conditions or advance the nursing profession. The hospital industry, in cooperation with Silicon Valley and Wall Street, will use AI to further its dangerous effort to displace RNs from the physical care of their patients prioritizing low-cost or free labor over patient needs.”

‘You can’t love something that isn’t there’: readers on how the sounds of nature have changed around them | Environment | The Guardian

1 Share

The sounds of our natural world are changing dramatically. Earth’s wildlife populations have plunged by 69% in fewer than 50 years. Fading along with them are many of the distinctive soundscapes of nature: the night-time calls of mammals, morning chorus of birds and buzz of insects.

This global story is stitched together by many local stories of loss. We spoke to readers about how natural sounds are changing where they live.

When I was a teenager in the 90s, I used to sneak out a lot to go to raves. I used to get back home at like six in the morning and always hated the noise the birds made outside my window. Even after 12 hours of blaring techno, the birds were so loud I never was able to sleep.

I’ve just temporarily moved back to that same childhood bedroom in the commuter belt of Munich having spent 15 years working as a photographer in the US. Now, there is literally no noise when I have my window open. No birds at all.

It’s a dire reminder of what we lost in such a short time. When I was 16 and you drove from one town to the next one you would need to clean the windscreen. Now you can drive for seven hours on the highway, and there is nothing. We only have blackbirds and sparrows in the garden, all the other birds are pretty rare – my parents freak out when they see them.

Now I feel nostalgic for those early morning bird noises, but I don’t think they’ll come back.
Oliver Fiegel, Munich, Germany

My husband and I built our house in the woods in New Brunswick in 1985. We were able to buy 50 acres of woodlot and build a modest home. When the sun came up in the early morning in spring and summer the cacophony of birdsong was so loud we’d have to shut our bedroom window in order to grab another hour or two of sleep. I am not a birder but my family has noted various warblers, thrushes, sparrows and thrashers over the years.

That ended long ago. I think I began really noticing the difference in the early 2000s, around the time our daughter was going to university. It seems as if it’s the migratory songbirds in particular that are disappearing. Yes, my hearing probably isn’t what it was 40 years ago, but honestly, the difference in volume and diversity of song is devastating to experience. The world we are leaving our children and grandchildren is going to be a very different place, I fear.

There is a beautiful cherry tree in my parents’ garden which used to be buzzing with bees. It looks like a bride when it’s in bloom with this amazing white blossom. It was like standing under a beehive. When I was a kid I was afraid of insects, but now I’m 42, I know there isn’t anything to be afraid of.

Whenever I was feeling gloomy about the future, looking at this tree would allow me to pretend for a while that things were normal. But for a couple of years in a row now, the tree has been blooming a month earlier than it used to, when the bees are not yet around. Occasionally, there is a solitary bee on the tree, but that is rare. Every day I walk under that cherry tree in full bloom and hope to hear that humming but get disappointed.

This tree was planted by my grandfather 55 years ago. He loved nature. If he were here today I think he would be walking around shaking his head. I will take over this garden at some point, and I wonder what types of plants I will be able to have when I am old. In times when the world seems to be going in the wrong direction it would be nice to have certain things remain unchanged – especially those that really matter.

I miss the fruity song of a blackbird that used to sing from a nearby tree in the evening. The chattering of tits. The hum of insect life. With the total disappearance of swifts and swallows, goldfinches and other garden birds (despite feeders), I feel very alarmed and very saddened.

I am 89 and this is so different from my memories of childhood, when the cuckoo always heralded the onset of summer warmth and swifts and swallows were a regular part of the summer scene. I recall the title of a book (which I’ve never read): Silent Spring, by Rachel Carson. Was this present time what she was writing about so prophetically?
Reader from Essex, UK

I miss the sound of the bullfinches. We usually heard their sweet single whistle before we saw them in our garden – I always knew they were about to arrive. They would usually appear in pairs – I found there was something reassuring and old-fashioned about that.

We’ve lived here for 30 years, and they’ve been here since the beginning. They can stick together for life – it’s comforting to think of them raising a brood together, just like we have in this house. My wife remembers watching them feeding on the sunflower seeds in the garden when she was feeding our daughter Emily. She and our son Ben loved watching them.

Looking back through my Garden Birdwatch for the British Trust for Ornithology I see that from 2003 to 2020 they were regularly observed for more than 15 weeks a year. Slowly they started to tail off and in the past four years it’s really noticeable – they didn’t visit us at all in 2023. Something must have changed in our area, like a hedgerow has gone or a field is being used differently. I’m not sure, but I’m missing them and wondering where they’ve gone.
Peter Gray, Chesterfield, UK

I was born in 1982 and lived in Norwich, in the east of England, until I was 25. I used to spend a lot of time outdoors in the countryside and at the coast, and developed a close connection with the natural world. While not a birder by any means, I was familiar with the songs and calls of many species, and loved listening to the blackbird and robin in our garden. Yet it was not until very recently that I realised my childhood experiences of bird song had been drastically impoverished, compared with if I had grown up in the 1950s. Since the postwar period, populations of nightingales and turtle doves have plummeted by more than 90%.

This decline has been so drastic that most people, including myself, have never encountered the beguiling songs of these summer visitors. But what’s more terrifying is that most people, again including myself, don’t realise these species are missing. Their eradication has been so swift and so complete that we’ve forgotten they used to exist at all.
Alex Smalley, Cornwall, UK

Curlews. My favourite sound in all the world and the sound of Cumbria. This time of year they should be calling over the fields here as they come inland to breed. Only 15 years ago you’d hear dozens. This year I’ve heard only one heartbreakingly lonely call in the night. There is no wild sound quite like the curlew – with each loss like this we lose the singularity of place which inspires us to care for it. You can’t love something that isn’t there.
Heidi Bewley, Cumbria, UK

I have lived here in Skåne for 35 years. When we first moved in there were several swallow pairs with nests under the farmhouse eaves and in various outhouses. Last year there was just a single pair. I miss their twittering when they first arrive and when they are hunting insects high and low.
