The Perseverance robot, which arrived on Mars on February 18, has already sent it to us more than 20 thousand images of the planet, captured with the 23 cameras (mostly color) that you have on board. And after shooting rocks, swirls e até helicopters, he got some time to follow a NASA tradition: a selfie.
The image was posted on Tuesday (6) on the rover's official Twitter account, with the caption “Portrait of the artist as a young robot”.
This Wednesday afternoon, Perseverance posted another selfie, this time accompanied by a friend: the Ingenuity helicopter, which is due to perform its first test flight in the next few days.
The photos were taken with an instrument called Watson (Wide Angle Topographic Sensor for Operations and eNgineering), a high-resolution camera designed to photograph rocks and mounted on the tip of the rover's robotic “arm”
The large circular lens in the upper right corner of the robot’s head is the SuperCam, a laser spectrometer used to analyze the composition of rocks. The two “silver rectangles” around the neck are the Mastcam-Z lenses, the “eyes” of the robot. They were created to take 3D photos and record high-resolution videos.

The name is a combination of “Mast”, the “mast” on which it is mounted, “cam”, camera and zoom “Z”, an unprecedented feature in a Martian rover. According to NASA, the magnification is powerful enough to see a fly at a distance equivalent to the length of a football field.
The two circular openings on the sides of the Mastcam-Z are another camera, the Navcam, used for navigation and also for making 360-degree panoramic photos of the terrain. In addition, Perseverance has front and rear obstacle detection cameras, Hazcams (Hazard Hazard).
NASA's other rover operating on Mars, Curiosity, also “has a custom” of making selfies. It is not a matter of vanity, but a way that NASA engineers have found to visually inspect the state of their robots.
Unfortunately they will not meet. The distance between the Jezero crater, where Perseverance is, and the Mount Sharp, home of Curiosity, is more than 3.700 km
