在离开马里兰州劳雷尔的约翰霍普金斯应用物理实验室（APL）仅两天后，NASA的双小行星重定向测试（DART）航天器就抵达了加利福尼亚——它在地球上的最后一站。 在约翰霍普金斯APL的一间洁净室里，DART航天器被转移到一个专门的运输集装箱中，穿运往加州隆波克附近的范登堡空军基地，DART计划在下个月底从那里发射。 影像来源：NASA/Johns Hopkins APL/Ed Whitman DART被放在专门的集装箱中，被小心翼翼地捆绑在一辆半拖车的甲板上，在约翰霍普金斯应用物理实验室的一小群团队成员的跟随下，从马里兰州穿越美国来到加州的范登堡太空部队基地。他们于本月初抵达。 影像来源：NAS

这幅NASA毅力号火星车的插图显示了其两个麦克风的位置。 影像来源：NASA/JPL-Caltech 六轮航天器上的两个麦克风为科学家和工程师探索这颗红色星球的方式增添了新的维度。 多亏了NASA毅力号火星车上的两个麦克风，这项任务记录了近5个小时的火星阵风，火星车车轮碾过沙砾的嘎吱声，以及探测器移动手臂时马达发出的嗡嗡声。这些声音让科学家和工程师能够以新的方式体验这颗红色星球——并且邀请每个人都来聆听。 “就好像你真的站在那里一样，”在法国法国天体物理学和行星学研究所研究麦克风数据的行星科学家巴普蒂斯特·奇德说。 “火星的声音具有强烈的低音振动，所以当你戴上耳机时，你能真正感受到它。 我认为
