NASA’s Perseverance Mars rover landed on the Red Planet on Feb. 18, 2021, and took this selfie over a rock nicknamed “Rochette,” on Sept. 10, 2021, the 198th Martian day, or sol of the mission. Two holes can be seen where the rover used its robotic arm to drill rock core samples.

See the other selfies Perseverance took on that day!

Perseverance uses a camera called WATSON (Wide Angle Topographic Sensor for Operations and eNgineering) on the end of its seven-foot-long (two-meter-long) robotic arm to take its selfies.

Here’s a detailed explanation of how the rover takes selfies.

2021年2月18日,NASA的毅力号火星车在火星上着陆,并在2021年9月10日,即任务的第198个火星日,在一块昵称为罗切特的岩石上拍下了这张自拍。照片中可以看到岩石上有两个洞,这是火星车用它的机械臂钻取岩芯样本留下的痕迹。

请看毅力号在那一天拍摄的其他自拍照片!

毅力号在它7英尺(2米)长的机械臂末端安装了一台名为WATSON(用于操作和工程的广角地形传感器)的相机来拍摄自拍。

下面是探测器如何自拍的详细说明
