Video: 00:04:20

Relive the Vega-C launch, flight VV25, from various angles.

The third Copernicus Sentinel-1 satellite, Sentinel-1C, has launched aboard a Vega-C rocket, flight VV25, from Europe’s Spaceport in French Guiana. The rocket lifted off on 5 December 2024 at 22:20 CET (18:20 local time).

Sentinel-1C extends the legacy of its predecessors, delivering high-resolution radar imagery to monitor Earth’s changing environment, supporting a diverse range of applications and advance scientific research. Additionally, Sentinel-1C introduces new capabilities for detecting and monitoring maritime traffic.

The launch also marks Vega-C’s ‘return to flight’, a key step in restoring Europe’s independent access to space. Vega-C is the evolution of the Vega family of rockets and delivers increased performance, greater payload volume and improved competitiveness.

Swarm vs. space radiation – the first 10 years

image

Swarm constellation

Satellites in orbit can become absentminded. Space radiation randomly flips onboard memory bits, potentially corrupting mission data and functionality. To better understand how this invisible onslaught works in practice, a team systematically analysed how radiation affected the memories of ESA’s three Swarm spacecraft during a decade of mapping Earth’s magnetic field.

XMM-Newton celebrates 25 years of breakthroughs

image

Today, ESA’s powerful X-ray observatory, XMM-Newton, celebrates 25 years in space. From planets to black holes, the space telescope has delivered many ground-breaking observations of a variety of celestial objects. And the mission is still going strong as recent results testify. We take a look at five fascinating discoveries from the last five years.

Description:

Deep dive into Salvatore Pais' patents and the #science of #zero #point #energy.
Asking Salvatore Pais about the #MH370 videos.
Discussing Cold #Plasma and EVOs

Navy Engineer Salvatore Pais knew the orbs were about to create wormhole in the MH370 drone video the very first time he saw it.

He says that the orbs are conditioning the vacuum around the aircraft with non-ionizing radiation. They establish a resonance effect to build up the electromagnetic field strength in order to break the Schwinger Limit.

I asked him if he's seen other videos like this and he says that even if he had he wouldn't be allowed to say since it would reveal surveillance methods.

There's no such thing as 'fake' military videos filmed in #infrared and IR depicting real science based on zero point energy. Let alone ones of a real missing civilian airliner that hasn't been found in 10 years.

Our technology should not advance faster than our humanity. 🤔


Is that another damn AI picture? How can you post it? You always warn about the dangers yourself, don't you?

Yes it is #AI generated and yes I warn of the dangers. Unfortunately, my posts without pictures are mostly ignored. I also have the feeling that most people don't really understand the extent of the threat. Pandora's box can no longer be closed. We can only try to deal with it #responsibly. I do think there's a difference between posting AI images and developing #Skynet.

I am working on a #FAQ on the subject of AI and hope to have enough time over Christmas to present the first parts of it to you. So please stay tuned and continue to be critical.

Dog domestication happened many times, but most didn’t pan out - Ars Technica https://arstechnica.com/science/2024/12/dog-domestication-happened-many-times-but-most-didnt-pan-out/

All modern dogs trace their roots to a single group of wolves (now extinct) that lived in Siberia around 23,000 years ago. But sometime between 11,300 and 12,800 years ago, the canines from Hollembaek Hill and another Alaskan site called Swan Point had dog DNA that doesn’t seem related to modern dogs at all. That may suggest that dog domestication was a process that happened several times in different places, creating several branches of a dog family tree, but only one stuck around in the long run.

Personally I'm happy just to be outside and enjoy the nice view.

Collecting data from the most extreme places on Earth can require the skills of the most extreme outdoor enthusiasts. Surrounded by glaciers and roughly 6,400m (21,000ft) above sea level, Willie Benegas spotted a pop of green moss wedged in granite. "Wow, this is an odd place for moss to be," he observed. In 2011, Benegas, an extreme mountaineering guide, was 500ft (152m) above the steep, exposed terrain of Mount Everest's Camp 2 and – despite having summited Mount Everest over a dozen times – he still found himself "impressed". Using a sterilised cloth Benegas scooped the moss into an envelope to be transported to a lab on another continent.

Benegas collected the moss samples for the non-profit Adventure Scientists, which acts as a matchmaking service between outdoor enthusiasts and scientists. "Scientists like to have samples taken in locations where it's difficult – sometimes damn near impossible – to get funding [to go]," McDermott says. "I was flabbergasted [Adventure Scientists] were even willing to try."

"Climbing is selfish," says Hari Mix, a mountain climber who collected data for Adventure Scientists during his Himalayan expeditions in 2012 and 2013. "There's no real point to it. I was looking for ways to add meaning or some kind of contribution to my trips."

In Washington State, John Soltys, a long-time volunteer for Adventure Scientists, says data collection bestows a sense of "purpose" on his family's alfresco activities. Soltys stumbled upon Adventure Scientists in 2013 while on a camping trip to Berkeley Park in Mount Rainier National Park, Washington State. Soltys's young children became "absolutely mesmerised" by the scurrying pikas – mountain-dwelling, mouse-like mammals. Soltys scoured iNaturalist, a social network for sharing biodiversity finds. There, he found Adventure Scientists, which was also utilising the platform to collect data on pikas. His family now volunteers with the nonprofit 100 times a year, he says. "Yeah, we're doing that crazy stuff," he says.

Well, good for them, I suppose. Sounds a bit too much like work to me. The "point" of being outside is to be outside and not at a screen thinking about stuff. Having a checklist of activities to do would be a big Nope, but hey, anyone who wants to climb 6,000 metres to collect some moss... more power to 'em, I say.

Just half a pound of the stuff may remove as much carbon dioxide as a tree can, according to early tests. Once the carbon is absorbed by the powder, it can be released into safe storage or be used in industrial processes, like carbonizing drinks.

"Half a pound ?" "As much as a tree ?" These are strange units indeed, Guardian...

In the lab, Yaghi’s team tested the new powder and found that it could successfully absorb and release carbon more than 100 times. It fills up with carbon in about two hours, and then must be heated to release the gas before starting the process over again. It only requires a temperature of about 120F to release the carbon; that makes it an improvement over other methods, which require a much higher temperature.

That feature means places that already produce extra heat – such as factories or power plants – could use it to release the gas and start the cycle again. The material could be incorporated into existing carbon capture systems or future technology.

Yaghi says he could imagine a future in which people build large plants using the material in every city of 1 million people or more around the world. He has plans to scale the use of this type of carbon capture with his Irvine, California-based company, Atoco, and believes the powder can be manufactured in multi-ton quantities in less than a year.

Dear Christoph,

I love snowflakes and I have an antique snowflake brooch that I wear in the Winter. Ding one Christmas season you explained that a snowflake is a fractal. I didn’t know what a fractal was, so you explained, and also sent a green, digital fractal Christmas tree. I knew of the many examples of fractals, but I didn’t know the proper name for them. I also especially love spirals.

FRACTAL - A fractal is a never-ending pattern. Fractals are infinitely complex patterns that are self-similar across different scales. They are created by repeating a simple process over and over in an ongoing feedback loop. Driven by recursion, fractals are images of dynamic systems – the pictures of Chaos. Geometrically, they exist in between our familiar dimensions. Fractal patterns are extremely familiar, since nature is full of fractals. For instance: trees, rivers, coastlines, mountains, clouds, seashells, hurricanes, etc. Abstract fractals – such as the Mandelbrot Set – can be generated by a computer calculating a simple equation over and over.
