NASA has selected Relativity Space to build and launch Aeolus, a 2028 Mars orbiter that would provide daily global measurements of dust, winds, and atmospheric temperatures to support future robotic and human missions. TechCrunch reports: The structure of the contract is akin to the deals that NASA made with SpaceX to fly cargo to the International Space Station, or Firefly Aerospace to put a lander on the Moon. The government agency handles the science, while the private company provides low-cost infrastructure. Aeolus, as the mission is dubbed, will contain four instruments to measure and image Mars from orbit, providing what NASA expects to be the first daily, global view of dust, winds, and temperature in its atmosphere. The agency said that data will make it safer for landers and, someday, astronauts, to visit the surface of the Red Planet. By pairing NASA's world-class instruments with commercial innovation and investment, we can deliver more science, more often, and reduce the time it takes to get essential data into the hands of researchers preparing for future human missions to Mars," NASA administrator Jared Isaacman said in statement. The mission is set to launch in 2028 -- a rapid pace that will require Relativity to design and build the spacecraft to carry the Aeolus instruments, and finish building the rocket that will carry it to space, all on a tight timeline. NASA did not disclose how much it is paying Relativity for the mission, and Relativity did not respond to questions from TechCrunch. Relativity was founded in 2015 by two former SpaceX and Blue Origin engineers, with the idea of using 3D printing to its maximum potential as a path to building a cheaper rocket. The company's first design, Terran-1, launched in March 2023 and failed mid-flight. Relativity doubled down by moving on to a larger design, dubbed the Terran R. Before Relativity could get it to the launch pad, the company ran into fundraising challenges, and Schmidt took a majority stake in the company in it last year, installing himself as CEO. He's been tight-lipped about the investment but has expressed interest in orbital data centers, and is thought to be using Relativity to launch a space telescope, Lazuili, financed by his family philanthropy, Schmidt Sciences.

Rolls-Royce Secures Deal To Build Small Nuclear Reactors For Sweden

Rolls-Royce SMR has secured a multibillion-pound agreement to build three small modular reactors on Sweden's west coast, "marking a major step in the British engineering group's ambition to become a leading supplier of the technology in Europe," reports Euronews. From the report: Following a rigorous selection process that started in 2022, UK engineering giant Rolls-Royce's nuclear division, Rolls-Royce SMR, won the contract to build nuclear reactors for Sweden. As part of the deal, the group, selected by Videberg Kraft as its partner, will deliver three Small Modular Reactors (SMRs) to Sweden's west coast, at the Varo Peninsula. "The Videberg Project will build Sweden's first new nuclear power plant in more than forty years, supporting industries and households in southern Sweden," a press statement from Rolls-Royce said. The partnership with utility Vattenfall and developer Karnfull Next is seen as one of the most advanced opportunities for deployment outside of the UK. [...] The European Commission considers small modular reactors (SMRs) to be a promising low-carbon technology that could help support the bloc's clean energy and energy security goals. In order to remove regulatory barriers, the EU's SMR strategy was adopted in March 2026 to accelerate the development and deployment of the technology across Europe. SMRs are smaller than conventional nuclear power plants, typically generating between 20 and 300 megawatts of electricity. At the upper end of that range, a reactor could produce around 7.2 million kilowatt-hours of electricity per day -- enough to power hundreds of thousands of homes. The International Energy Agency (IEA) estimates that more than 1,000 small modular reactors could be deployed worldwide by 2050 under a supportive policy scenario, requiring cumulative investment of around $670 billion.

Trump Admin Backs Off Plans To Kill Ocean Monitoring

An anonymous reader quotes a report from The Guardian: In May, the federal government announced without warning that it would take apart a network of ocean monitoring systems that it had spent over $350 million to build. No reason was given for the decision to shut down the Ocean Observatories Initiative (OOI), but suspicion immediately focused on the network's role in tracking climate change. But the OOI also provides data that's useful for weather forecasting and fisheries management, leading to widespread opposition. Today, it appears that the opposition has won, as the government will announce that it's reversing the decision. The big remaining question is how much damage the OOI took during the intervening month. [...] The OOI is a federally supported resource that provides ocean data for use by academic researchers, government planners, and private companies. It consists of arrays of monitoring systems in several locations in both the Atlantic and Pacific Oceans that can track things like currents, salinity, chemical levels, temperatures, and tectonic activity. (There are over 100 individual entries on the page that display the data gathered by the system.) Obviously, there are many potential uses of that data. The fact that it has been gathered continuously for a decade means it can help track changes in how carbon dioxide and heat enter the oceans. This is probably what made it a target for the climate change denialists who helped set the Trump administration's policy. Those policymakers are perfectly happy to annoy people with environmental concerns, but they apparently neglected to consider how upset everyone else would be about losing access to the other data. The ensuing public backlash led the Senate on Wednesday to unanimously agree with a measure that would block the government from taking down the OOI. Today's decision may indicate that the administration recognized it had gotten itself into a fight it knew it was losing. The National Science Foundation formally announced the decision, stating: "effective immediately, [it] will not proceed with further removal or descoping of equipment from the remaining arrays and will continue operations including planned maintenance." The agency added that it "appreciates the concerns raised by the range of stakeholders that have informed us they rely on data" from the OOI. The NSF also said it would "issue a Dear Colleague Letter to collect input from stakeholders and convene an expert panel to assess observational needs, evaluate available data sources, consider responses ... and help the agency identify a sustainable path for NSF's ocean observing systems."
