A Dust ****** Photobombs Perseverance!

To celebrate her 1,500th Martian day (“Sol”) exploring the red planet, the Perseverance rover used its robotic arm to take a selfie of the rover and the surrounding landscape. But when team members reviewed the photo, they were surprised to find that Perseverance had been photobombed!  

As the rover sat at the “Pine Pond” workspace, located on the outer rim of Jezero crater, which it has been exploring for the past several months, the Wide Angle Topographic Sensor for Operations and eNgineering (WATSON) camera on the end of its arm was used to acquire a 59-image mosaic of the rover. This is the fifth “selfie” that Perseverance has acquired since landing on Mars in 2021. The rover’s robotic arm is not visible in the self portrait because — just like a selfie you would take with your own cellphone camera — rover operators make sure not to have the arm get “in the way” of the body of the rover. This is even easier to do on Mars because Perseverance needs to take 59 different images at slightly different arm positions to build up the selfie, and the elbow of the robotic arm is kept out of the way while the images are acquired.

These are relatively common phenomena both on Mars and in Earth’s desert regions, and form from rising and rotating columns of warm air, which gives the appearance of a dust tornado. Just like many other weather patterns, there is a peak “season” for dust-****** activity, and Jezero crater is in the peak of that season now (late northern spring).  The one seen in the selfie is fairly large, about 100 meters, or 328 feet, across. While Perseverance regularly monitors the horizon for dust-****** activity with Navcam movies, this is the first time the WATSON camera on the end of the robotic arm has ever captured an image of a dust ******!

, thought to have formed by volcanic eruptions or impacts early in Martian history. Later, this ancient rock was uplifted during the impact that formed Jezero crater. Now that the rover has successfully acquired the spherule sample the science team was searching for, Perseverance is leaving the area to explore new rock exposures. Last week, the rover arrived at an exposure of light-toned bedrock called “Copper Cove,” and the science team was interested to determine if this unit underlies or overlies the rock sequence explored earlier. After performing an abrasion to get a closer look at the chemistry and textures, the rover drove south to scout out more sites along the outer edge of the Jezero crater rim.
