洞察号的最后一张自拍
NASA’s InSight Mars lander took this final selfie on April 24, 2022, the 1,211th Martian day, or sol, of the mission. The lander is covered with far more dust than it was in its first selfie, taken in December 2018, not long after landing – or in its second selfie, composed of images taken in March and April 2019.
The arm now needs to move several times in order to capture a full selfie. Because InSight’s dusty solar panels are producing less power, the team will soon put the lander’s robotic arm in its resting position (called the “retirement pose”) for the last time in May 2022.

NASA的洞察号火星车在2022年4月24日拍摄了这张最后的自拍，这一天是该任务的第1211个火星日。与2018年12月着陆后不久拍摄的第一张自拍相比，火星车上的灰尘要多得多，也比2019年3月和4月拍摄的第二张自拍中的灰尘要多。
机械臂现在需要移动几次才能拍摄完整的自拍照。由于洞察号布满灰尘的太阳能电池板产生的电力较少，该团队很快将在2022年5月最后一次将火星车的机械臂置于静止位置（称为“退休姿势”）。
