Permaculture
I watched a brief video yesterday explaining permaculture (permanent agriculture). It was interesting but quite limited as it was fundamentally an ad for the presenter's book on permaculture.
I'll not be buying the book but I may well investigate permaculture a little further.
Just by the by, I shan't buy it because my age related enfeeblement means an hour in the garden leaves me worn out and it would take many hours to achieve the results that appear in the small garden in the video.
That's my exculpation taken care of :)

How marine heatwaves impact phytoplankton and ocean health
Marine heatwaves – periods of prolonged, unusually warm seawater – are increasingly threatening marine ecosystems around the world. A recent study, led by the Institute of Marine Sciences of the National Research Council of Italy (CNR-ISMAR) as part of ESA’s CAREHeat project, specifically examined these effects in the North-Western Mediterranean Sea.
By combining satellite data from ESA’s Climate Change Initiative (ESA CCI), in situ robotic platforms called BioGeoChemical-Argo floats and Copernicus Marine’s biogeochemical models, the research highlights how these heatwaves significantly disrupt the spring phytoplankton bloom – a vital process for marine life.

Crowdsourced voting fraud claims could become grist for Republican lawsuits
One hub for rumors and conspiracies about voting is X, the social media site once known as Twitter. There, users are floating unverified and false claims about voting that can quickly go viral.

in reply to FishLake • • •Maybe they can just tether two ships together and have them rotate around a common CoG like a bucket swinging around on a string. Wouldn't be that expensive. The radiation I'm not sure, maybe they can create a "safe room" on the ship surrounded by their water reserves.
The tether thing is so simple I'm surprised it wasn't in use decades ago. I think I remember them confirming it being a viable option on Gemini when they tested it being tethered to the test vehicle.

in reply to TimeSquirrel • • •Unless someone nasa/or musk, starts looking at the effects of centrifugal gravity on long term health.
Its just not going to happen. Atm anyone travelling to Mars is unlikely to be fit to explore by landing. Given the trip length.
But we have understood centrifugal artificial gravity since before space flight, and planned to experiment on iss.
But cheep politics has not bothered.

in reply to brlemworld • • •Yep. That is more about getting weight into space. As we know water can provide protection.
But the issue of moving water from earth to space then building a 2 layered craft strong enough to surrou d passengers with a foot or more of water. While doable theoretically. Is just a huge huge task.
If mankind is seriose about such. Robotic collection of ice from space is more practice. Moving it towards earth using it to create hydrogen and oxygen slowly via solar. Then using that to move the water itself into earth near orbit. From there building a vessel able to rotate and protect occupants from radiation etc would be possible.
But seriosly the amount of work involved. Mars really is not the best place to go. Once humanity has developed the ability to generate graverty. Confirmed mankind can live is centrifugal generated enviroments. And developed to robotics to move ice and asteroids into orbit.
Honestly building O'Neil station like structures would be healthier then trying to live in 1/3 g of Mars anyway. Mars is worth learning about. But musks population pl
