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.

December 7, 2024
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.

Relive Sentinel-1C on Vega-C launch

image

Video: 02:31:24

The third Copernicus Sentinel-1 satellite, Sentinel-1C, launched aboard a Vega-C rocket, flight VV25, from Europe’s Spaceport in French Guiana 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.

Proba-3 launch campaign replay

image

Video: 00:01:21

Proba-3 lifted off on its PSLV-XL rocket from Satish Dhawan Space Centre in Sriharikota, India, on Thursday, 5 December, at 11:34 CET (10:34 GMT, 16:04 local time). The mission was launched using this Indian launcher because it needed to be placed in a highly elliptical orbit extending more than 60 500 km from the ground.

After integration and testing was completed at Redwire Space in Belgium, Proba-3 was transported to India to be prepared for launch.

The latest member of ESA’s family of in-orbit demonstration missions, Proba-3 is in fact two spacecraft being launched together, which will separate in orbit to begin performing precise formation flying, precise to a single millimetre, about the thickness of an average fingernail. To prove their performance, Proba-3 has been devoted to an ambitious scientific goal. The pair will line up precisely with the Sun 150 m apart so that one casts a precisely controlled shadow onto the other.

By blocking out the fiery disc of the Sun, Proba-3’s ‘Occulter’ spacecraft will mimic a terrestrial total solar eclipse, to open up views of the Sun’s faint surrounding atmosphere, or ‘corona’, which is a million times fainter than its parent star. Proba-3’s second ‘Coronagraph’ spacecraft hosts the optical instrument that will observe the solar corona.

If Proba-3’s initial commissioning phase goes to plan then the spacecraft pair will be separated early in the new year to begin their individual check-outs. The operational phase of the mission, including the first observations of the corona through active formation flying, should begin in about four months.

Proba-3 was led for ESA by Sener in Spain, overseeing a consortium of 14 ESA Member States and Canada including Airbus Defence and Space in Spain manufacturing the spacecraft and Redwire Space in Belgium responsible for the spacecraft avionics, assembly and operations. CSL in Belgium produced Proba-3’s ASPIICS coronagraph Spacebel in Belgium developed the onboard and ground segment software with GMV responsible for the formation flying system and flight dynamics.

The power of two: Proba-3

Video: 00:02:32

ESA’s eclipse-making Proba-3 double satellite mission has made it to space! Learn more about Proba-3 from the mission team as they bid farewell to their spacecraft, while ESA's Director General Josef Aschbacher wishes the team the best of luck.

The latest member of ESA’s family of in-orbit demonstration missions, Proba-3 is in fact two spacecraft being launched together, which will perform precise formation flying, accurate to a single millimetre, about the thickness of an average fingernail.

Proba-3's PSLV-XL liftoff

A pair of spacecraft were launched together today from India with the potential to change the nature of future space missions. ESA’s twin Proba-3 platforms will perform precise formation flying down to a single millimetre, as if they were one single giant spacecraft. To demonstrate their degree of control, the pair will produce artificial solar eclipses in orbit, giving prolonged views of the Sun’s ghostly surrounding atmosphere, the corona.
