使命召唤NASA“好奇号”火星车终于抵达期待已久的含硫酸盐区域_我的网站
一 | NASA在周三的声明中把含硫酸盐的区域描述为“长期寻找的区域 ”和 “特殊的”。
二 | "There cannot be shortcuts or fast tracks to the membership itself. The EU covers so many areas, and at the very heart of the EU is the single market. And the single market cannot function if, in one part of it, not all rules, regulations, standards are being followed. So, a very thorough work needs to be done by the Ukrainians," Maasikas told Euronews.,The ambassador also denied that the massive accession questionnaire, which Ukrainian President Volodymyr Zelensky handed over to Maasikas after submitting Ukraine's membership application, was mostly filled out by EU officials rather than the Ukrainian government itself.,Zelensky Touts Ukraine's EU Candidate Status as 'Biggest Step Toward Stronger Europe'23 June, 23:02 GMT,Zelensky signed the application for Ukraine's accession to the EU on February 28, a few days after the start of the Russian special operation. During the EU delegation's visit to Kiev on April 8, Zelensky received a questionnaire to begin Ukraine's accession process and returned it to Maasikas on April 18.,On June 23, the EU approved granting Ukraine the status of a candidate for joining the bloc. Gaining the candidate status is the first step in a long process of accession. Turkey has been a candidate since 1999, North Macedonia since 2005, Montenegro since 2010, and Serbia since 2012. Croatia was the latest country to join the EU in 2013 after a ten-year accession process.。该航天局的火星勘测轨道飞行器(MRO)在“好奇号”于2012年抵达盖尔陨石坑之前就已经勘察了该地区,因此研究人员期待近距离观察已经有一段时间了。
三 | “好奇号”没有浪费任何时间来熟悉这个地区。NASA表示:“到达后不久,该漫游车就发现了各种各样的岩石类型和过去水的迹象,其中有爆米花纹理的结核和含盐矿物,如硫酸镁(泻盐是一种)、硫酸钙(包括石膏)和氯化钠(普通食盐)。”该漫游车最近钻进了一块名为“Canaima”的岩石,以仔细观察其化学和组成。“好奇号”就像一个轮子上的科学实验室,所以它正在使用车载设备来分析它从岩石中提取的样本。在其他方面,“好奇号”将寻找可能存在的任何有机分子的迹象。自从“好奇号”的“同胞”漫游者在杰泽罗陨石坑发现一些有机物以来,火星上的有机物最近一直是一个热门话题。请记住,有机分子的发现并不一定证明火星上曾经存在过微生物生命。“好奇号”正在帮助科学家们解决一些关于含盐矿物的起源问题,这些矿物可能是在这个星球的过去几十亿年前干涸的溪流和池塘留下的。NASA表示:“假设这个假设是正确的,这些矿物提供了诱人的线索,说明红色星球的气候是如何--以及为什么--从更像地球变成今天的冰冻沙漠的。”“好奇号”已经穿越了岩石(随着时间的推移,它的车轮受到了相当大的冲击)和沙子,以达到它现在的位置。除了很酷的科学成果外,回报是令人惊叹的景观。8月14日的全景图显示了圆润的火星山丘和布满岩石的沙丘的华丽景色。“好奇号”科学操作协调员 Elena Amador-French 谈到了对这些景色的敬畏感。“沙脊是华丽的。你可以在上面看到完美的小漫游车足迹。”Amador-French 谈到全景图中看到的山口时说:“悬崖峭壁很美--我们真的很接近山壁了。”“好奇号”只是刚刚开始研究含有硫酸盐的地区的秘密。它也让漫游者团队忙于研究如何在保证“好奇号”安全和功能的同时,在岩石和沙地上航行。Amador-French说:“科学成果越多、越有趣,火星上的障碍似乎就越多。 Current article:http://ia7jn1z.yindabobiehonggaonumiao.bond/news/20260826_1855407.html Published on:12:53:49 |
