NASA 宣布，因种种原因多次推迟的 ESA Rosalind Franklin 火星漫游车将使用 SpaceX 的重型火箭 Falcon Heavy 发射到火星，最早发射时间是 2028 年。Rosalind Franklin 漫游车的历史可上溯到 1997 年，最初是 NASA 和 ESA 合作的项目，原计划 2018 年发射，但因为 NASA 在奥巴马政府任期内削减预算，美国退出了该项目。ESA 因此改与俄罗斯进行合作，计划 2020 年发射，但由于新冠疫情以及降落伞测试失败等问题，发射时间推迟到 2022 年。2022 年的俄乌战争促使 ESA 终止了与俄罗斯的合作。这一次美国再次伸出了援助之手，双方于 2024 年签署了合作协议。
I am trying to build a platform for complex discussions, given the inadequacy of existing social media for this purpose. The core idea is to enforce the structure that characterizes the development of an argument right at the level of the platform and discard everything else. The result is a place that is troll-proof by design and optimized for having complex discussions. You can read more about it at https://www.thesaner.com/faq and try out its behavior at https://www.thesaner.com/simulator . The website is functional, so you can also choose to sign up for it. The website remains very much a work in progress and I welcome all feedback. If you have any doubts, please ask about it. PS: The website only supports discussions on science, policy, and technology at the moment. I am working on making it general-purpose as soon as possible.
