NASA毅力号火星车将研磨这张照片中心的岩石，让科学家和工程师们评估它是否能承受火星车强大的钻头。 影像来源：NASA/JPL-Caltech 本周，毅力号火星车将研磨一块岩石，让科学家和工程师决定该目标是否能承受其强大的钻头。 在寻找火星上古代微生物生命迹象的过程中，NASA的毅力号火星车再次准备收集第一批岩芯样本，这些样品最终可能被带到地球上作进一步研究。 本周，火星车7英尺长（2米长）的机械臂上的一个工具将研磨一块绰号为“Rochette”的岩石的表面，让科学家可以观察内部，并决定他们是否要用火星车的取芯钻头采集样本。比铅笔略粗的样本将被密封在火星车上剩余的42根钛管中的一根。 如果团队决定从这块岩石中获取岩心，采样过程将在下周开始。 该任务试图在8月6日从一块岩石上获取他们关于陨石坑底部的第一个记录，但...
