NASA’s Perseverance rover captured a distinctive selfie on March 11, 2026, its 1,797th Martian day, or sol, during the rover’s deepest push westward beyond Jezero Crater. The selfie is composed of 61 individual images taken by the WATSON (Wide Angle Topographic Sensor for Operations and eNgineering) camera mounted on the rover’s robotic arm.
This image shows Perseverance focusing on the “Arethusa” rocky outcrop after creating a circular abrasion patch on the rock’s surface. In the background, the western rim of Jezero Crater is visible, marking the rover’s farthest westward position since landing.
The selfie was assembled after the images were transmitted back to Earth and stitched together. An alternate version of the selfie, known as Figure A, depicts the rover appearing to look directly at the camera. A GIF animation combines both images to simulate the rover looking up and down.
WATSON is part of the SHERLOC instrument (Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals), designed to study the mineralogy and organic compounds on Mars. The camera itself was developed by Malin Space Science Systems (MSSS) in San Diego and is operated jointly by MSSS and NASA’s Jet Propulsion Laboratory (JPL).
The Perseverance rover, managed by JPL at Caltech in Pasadena, California, continues to explore and analyze the Martian surface to advance scientific understanding of Mars’ geology and past habitability.
Why it matters
This selfie highlights Perseverance’s ongoing exploration beyond its initial landing site, providing scientists with detailed visual context of Martian geology as it investigates key rock formations for clues about Mars’ ancient environment. These observations may help answer questions about the planet’s potential to support life in the past.
Background
Launched in July 2020 and landing on Mars in February 2021, Perseverance is part of NASA’s Mars 2020 mission. Its suite of scientific instruments, including SHERLOC and WATSON, is aimed at seeking signs of past microbial life and collecting samples to eventually return to Earth. The rover’s selfies serve both as documentation of its activities and as tools for mission engineers to monitor its condition remotely.
