A |     A dark money group called the Resources Legacy Fund (RLF) that was awarded grant money by the Leonardo DiCaprio Foundation provided funds to a law firm linked to “climate nuisance lawsuits” across the United States, Fox News reports, citing findings made by the watchdog group Government Accountability & Oversight (GAO).,According to the media outlet, GAO managed to obtain emails that were exchanged between major philanthropist Dan Emmett and Ann Carlson, a climate professor at UCLA, in 2017 when they were working with a law firm called Sher Edling to raise money for the firm’s efforts to sue oil companies on behalf of state and local governments.,In their correspondence, Emmett and Carlson mention how Sher Edling’s director of strategic client relationships Chuck Savitt received help from Terry Tamminen in the latter’s capacity (at the time) as CEO of the Leonardo DiCaprio Foundation.,"Chuck Savitt who is heading this new organization behind the lawsuits has been seeking our support," Emmett wrote in one of the emails to Carlson. "Terry Tamminen in his new role with the DiCaprio Foundation has been a key supporter.”,He also forwarded a message to Carlson that Savitt had sent him a few days prior.,"Wanted to let you know that we filed the first three lawsuits supported by the Collective Action Fund on Monday," Savitt wrote in the missive. "These precedent setting cases call on 37 of the world's leading fossil fuel companies to take responsibility for the devastating damage sea level rise - caused by their greenhouse gas emissions - is having on coastal communities.",Con Artists Swindle Woman Out of Over $800,000 via 'Leonardo DiCaprio & Scientology' Scheme12 May, 18:57 GMT,As the media outlet points out, the Collective Action Fund for Accountability, Resilience and Adaptation was managed at the time by the RLF, and two months before the aforementioned correspondence was exchanged, the Leonardo DiCaprio Foundation announced that they would contribute some $20 million in grants to various climate and conservation causes, with one of the recipients of those grants being the RLF.,The said grant was awarded to the dark money group "to support precedent-setting legal actions to hold major corporations in the fossil fuel industry liable," Fox notes, adding that the announcement has since been deleted (although it remains archived).,Between 2017 and 2020, the RLF reportedly provided more than $5.2 million to Sher Edling, with the dark money group’s spokesman Mark Kleinman telling Fox that they had provided grants to the firm so the latter would “pursue charitable activities to hold fossil fuel companies accountable for the accuracy of information they had disseminated to consumers and the public about the role their products played in causing climate change.",Since 2017, Sher Edling has sued major oil companies on behalf of both state and local governments in the United States, alleging that the said companies have "deceived the public about climate change," with most of these lawsuits currently being ongoing, the media outlet adds.。

China's commercial reusable launch vehicle sector continues to make steady progress, as a company announced on Friday that it had completed a long-duration test firing of an engine for a large recoverable carrier rocket.
Deep Blue Aerospace, a commercial space startup based in Wuxi, east China's Jiangsu Province, said it recently completed a 100-second static-fire test of its Thunder-RS engine, a 130-tonne-class liquid-oxygen kerosene engine designed for the company's large reusable rocket, Nebula-2.
The test reached 1,297.5 kilonewtons of thrust, or about 132.3 tonnes. The company said multiple short-duration test firings had been conducted previously to evaluate engine performance, with no anomalies recorded.
The recent 100‑second run was the engine's first crossing of that steady‑state duration threshold, serving as a comprehensive verification of its performance, the company said.

Rocket reusability can greatly cut launch costs and boosts launch frequency, making it key to achieving large-scale, routine access to space.
China launched the reusable rocket Zhuque-3 on Wednesday morning, achieving its first recovery of a rocket's first stage on land, marking the country's first successful land-based recovery. This mission followed the successful sea-based net recovery of the Long March-10B's first stage on July 10.
More models of Chinese reusable rockets are scheduled to conduct tests this year.
