Ever wonder why NASA’s Mars rover keeps snapping pics of a tiny maze? Turns out, it’s not just for fun—this little labyrinth helps the rover’s Sherlock-inspired tool (yep, SHERLOC) stay sharp when hunting for signs of ancient life. The maze acts like a focus test for your phone camera, making sure the rover’s laser is spot-on. Bonus: NASA’s also testing spacesuit fabrics up there, so future astronauts can stay safe and stylish on Mars! #MarsRover #SpaceScience #NASA #Business
