ALT Engineers in cleanroom suits work on installing NASA's MOXIE instrument onto the Perseverance rover. The gold-colored, boxy device is suspended above the rover by a crane, with one technician guiding its placement. A black label on the image identifies the instrument with the text: "MOXIE – My oxygen-extracting experiment!" The scene takes place in a cleanroom facility, with additional personnel visible behind glass windows in the background.

ALT A side-by-side comparison of NASA’s Mars rovers: Curiosity (left) and Perseverance (right) are shown. Both six-wheeled rovers have a similar design, with robotic arms, cameras mounted on masts, and instrument-laden decks. Curiosity appears slightly more weathered and has simpler wheel treads, while Perseverance features more advanced instruments, sleeker design details, and redesigned wheels with thicker, zigzag treads for better durability on Martian terrain.

In the foreground, the back end of the Perseverance rover fills the lower right side of the frame. A gray, cylindrical antenna sits atop the left side of the rover. At the center of the rover is a white, metallic cylinder with flat cooling fins radiating from the center. On the right side is a flat, hexagonal antenna pointed at the sky.
