这篇讲什么
美国航天局“毅力”号火星车在耶泽罗陨石坑附近的切亚瓦瀑布岩石中钻取了名为“蓝宝石峡谷”的样本,其矿物纹理可能保存着远古微生物活动的痕迹。2025年9月《自然》杂志发表同行评审研究称,该岩石含有潜在生物特征,但尚未证实火星曾有生命。由于成本问题,火星样本返回计划已进入收尾阶段,这批珍贵样本能否回到地球实验室接受深入分析仍不确定。
原文开头
Inside a sealed tube on Mars, a small rock sample holds one of the most intriguing clues collected in the search for life beyond Earth. NASA’s Perseverance rover drilled it from a rock marked with unusual mineral patterns that scientists believe could preserve traces of ancient microbial activity. The sample, named Sapphire Canyon, has not established that Mars once hosted life. Its importance lies in a combination of chemistry and structure that deserves closer investigation, including tests that would be far more comprehensive in laboratories on Earth. That next step is now uncertain. The Mars Sample Return program intended to retrieve Perseverance’s collection has entered closeout, leaving the promising material without a confirmed journey home. …
