在这张9月1日导航相机拍摄的两张图片的合成图中，可以看到毅力号第二次样品采集尝试的钻孔。 图片来源：NASA/JPL-Caltech 毅力号在可能完成收集其第一个科学选择的火星样本的过程之前，将获得样本管的额外图像。 9月1日晚间从NASA的毅力号火星车上收到的数据表明，该团队已经实现了对火星岩石成功岩芯采样的目标。这一历史性事件发生后下传的最初图像显示，岩芯采样后样品管内存在一个完整的样本。然而，由于阳光条件不佳，机械臂完成样品采集后拍摄的其他图像并不确定。在继续进行样品处理之前，将拍摄另一轮光线较好的图像。 在进行火星岩石样本的密封和储存之前，获得额外的图像是该团队根据8月5日火星车取样尝
70米（330英尺）的14号深空站（DSS-14）是加利福尼亚州巴斯托附近戈德斯通深空通信中心最大的深空网络天线。 影像来源：NASA/JPL-Caltech DSN（Deep Space Network, 深空网络）正在进行升级，以便与比以往更多的航天器进行通信，并适应不断变化的任务需求。 当火星2020毅力号火星车在红色星球上着陆时，NASA的深空网络（DSN）就在那里，使该任务能够发送和接收数据，帮助实现这一事件。去年，当OSIRIS-REx采集小行星贝努的样本时，DSN发挥了关键作用，不仅向探测器发送指令序列，而且还将其令人惊叹的照片传回地球。 自1963年以来，DSN一直是NASA深
