In a Major New Report, Scientists Build Rationale For Sending Astronauts To Mars
A major scientific report published Tuesday argues that sending astronauts to Mars is justified by the quest to find life and conduct research that robots alone can't achieve. "We're searching for life on Mars," said Dava Newman, a professor in the Department of Aeronautics and Astronautics at Massachusetts Institute of Technology and co-chair of the committee that wrote the report. "The answer to the question 'are we alone' is always going to be 'maybe,' unless it becomes yes." Ars Technica reports: The report, two years in the making and encompassing more than 200 pages, was published by the National Academies of Sciences, Engineering, and Medicine. Essentially, the committee co-chaired by Newman and Linda T. Elkins-Tanton, director of the University of California, Berkeley Space Sciences Laboratory, was asked to identify the highest-priority science objectives for the first human missions to Mars. [...] "There's no turning back," Newman said. "Everyone is inspired by this because it's becoming real. We can get there. Decades ago, we didn't have the technologies. This would have been a study report." The goal of the report is to help build a case for meaningful science to be done on Mars alongside human exploration. The report outlines 11 top-priority science objectives. [...] The committee also looked at different types of campaigns to determine which would be most effective for completing the science objectives noted above. The campaign most likely to be successful, they found, was an initial human landing that lasts 30 days, followed by an uncrewed cargo delivery to facilitate a longer 300-day crewed mission on the surface of Mars. All of these missions would take place in a single exploration zone, about 100 km in diameter, that featured ancient lava flows and dust storms. Notably, the report also addresses the issue of planetary protection, a principle that aims to protect both celestial bodies (i.e., the surface of Mars) and visitors (i.e., astronauts) from biological contamination. [...] In recent years, NASA has been working with the International Committee on Space Research to design a plan in which human landings might occur in some areas of the planet, while other parts of Mars are left in "pristine" condition. The committee said this work should be prioritized to reach a resolution that will further the design of human missions to Mars. "NASA should continue to collaborate on the evolution of planetary protection guidelines, with the goal of enabling human explorers to perform research in regions that could possibly support, or even harbor, life," the report states.

'Food and Fossil Fuel Production Causing $5 Billion of Environmental Damage an Hour'
An anonymous reader quotes a report from the Guardian: The unsustainable production of food and fossil fuels causes $5 billion of environmental damage per hour, according to a major UN report. Ending this harm was a key part of the global transformation of governance, economics and finance required "before collapse becomes inevitable," the experts said. The Global Environment Outlook (GEO) report, which is produced by 200 researchers for the UN Environment Program, said the climate crisis, destruction of nature and pollution could no longer be seen as simply environmental crises. "They are all undermining our economy, food security, water security, human health and they are also [national] security issues, leading to conflict in many parts of the world," said Prof Robert Watson, the co-chair of the assessment. [...] The GEO report is comprehensive -- 1,100 pages this year -- and is usually accompanied by a summary for policymakers, which is agreed by all the world's countries. However, strong objections by countries including Saudi Arabia, Iran, Russia, Turkey and Argentina to references to fossil fuels, plastics, reduced meat in diets and other issues meant no agreement was reached this time. [...] The GEO report emphasized that the costs of action were much less than the costs of inaction in the long term, and estimated the benefits from climate action alone would be worth $20 trillion a year by 2070 and $100 trillion by 2100. "We need visionary countries and private sector [companies] to recognize they will make more profit by addressing these issues rather than ignoring them," Watson said. [...] One of the biggest issues was the $45 trillion a year in environmental damage caused by the burning of coal, oil and gas, and the pollution and destruction of nature caused by industrial agriculture, the report said. The food system carried the largest costs, at $20 trillion, with transport at $13 trillion and fossil-fuel powered electricity at $12 trillion. These costs -- called externalities by economists -- must be priced into energy and food to reflect their real price and shift consumers towards greener choices, Watson said: "So we need social safety nets. We need to make sure that the poorest in society are not harmed by an increase in costs." The report suggests measures such as a universal basic income, taxes on meat and subsidies for healthy, plant-based foods. There were also about $1.5 trillion in environmentally harmful subsidies to fossil fuels, food and mining, the report said. These needed to be removed or repurposed, it added. Watson noted that wind and solar energy was cheaper in many places but held back by vested interests in fossil fuel. The climate crisis may be even worse than thought, he said: "We are likely to be underestimating the magnitude of climate change," with global heating probably at the high end of the projections made by the Intergovernmental Panel on Climate Change. Removing fossil fuel subsidies could cut emissions by a third, the report said.

OpenAI Joins the Linux Foundation's New Agentic AI Foundation
OpenAI, alongside Anthropic and Block, have launched the Agentic AI Foundation under the Linux Foundation, describing it as a neutral home for standards as agentic systems move into real production. It may sound well-meaning, but Slashdot reader and NERDS.xyz founder BrianFagioli isn't buying the narrative. In a report for NERDS.xyz, Fagioli writes: Instead of opening models, training data, or anything that would meaningfully shift power toward the community, the companies involved are donating lightweight artifacts like AGENTS.md, MCP, and goose. They're useful, but they're also the safest, least threatening pieces of their ecosystem to "open." From where I sit, it looks like a strategic attempt to lock in influence over emerging standards before truly open projects get a chance to define the space. I see the entire move as smoke and mirrors. With regulators paying closer attention and developer trust slipping, creating a Linux Foundation directed fund gives these companies convenient cover to say they're being transparent and collaborative. But nothing about this structure forces them to share anything substantial, and nothing about it changes the closed nature of their core technology. To me, it looks like Big Tech trying to set the rules of the game early, using the language of openness without actually embracing it. Slashdot readers have seen this pattern before, and this one feels no different.
