Desert-lizard inspired rover wheels enable sand-swimming on Mars

German VaMEx researchers are developing a Mars-exploration rover system with curved, desert-lizard-inspired wheels that can 'swim' through sandy terrain, testing stability on dunes and open ground. The effort, led by the University of Würzburg with the German Space Agency (DLR) Bremen and the University of Bremen, aims to create autonomous, heterogeneous robot swarms to explore Valles Marineris on Mars. While tests show stable sand mobility and the generation of sinusoidal tracks, researchers note the need for software-driven control refinements to manage slippage and sinking, advancing mobility for future robotic (and crewed) Mars missions.

NASA's Mars Imaging Breakthroughs Transform Global Perspective

NASA's imaging technology has significantly advanced over the past 60 years, starting with Mariner 4's first images of Mars, leading to high-resolution cameras on orbiters and rovers like Viking, Pathfinder, Spirit, Opportunity, Curiosity, and Perseverance, as well as aerial views from the Ingenuity helicopter, transforming our understanding of the Red Planet.

"Developing a Solar Panel Cleaning Device for Mars Rovers"

NASA could design a mechanism to clean the solar panels on Mars rovers, but it would require sacrificing space or weight meant for scientific instruments due to constraints on deep-space missions. Engineers must work within a "resource box" defined by factors like mass, dimensions, power, schedule, data volume, and cost, making trade-offs between adding cleaning mechanisms and scientific capabilities. Despite the challenges, the focus remains on maximizing scientific output while staying within these constraints.

"20 Years of Mars Exploration: The Enduring Legacy of Spirit and Opportunity"

NASA's Spirit and Opportunity rovers, which landed on Mars 20 years ago, far outlived their warranties and made significant discoveries, including evidence of past water on Mars and potential habitats for microbial life. Opportunity set a record by covering more than a marathon distance on Mars. Their scientific accomplishments and robust engineering paved the way for larger rovers like Curiosity and Perseverance, and their experiences improved techniques for exploring Martian terrain. Today, their legacy continues through ongoing Mars exploration missions and the inspiration they provide to those in the field.

"NASA's Twin Rovers: 20 Years of Revolutionizing Mars Science"

NASA's twin rovers, Spirit and Opportunity, celebrated their 20th anniversary since landing on Mars, revolutionizing our understanding of the Red Planet. Their discoveries of ancient hot springs and evidence of water on Mars paved the way for future missions like Curiosity and Perseverance. The rovers' enduring legacy includes inspiring a new generation of scientists and engineers, and their remarkable durability surpassed all expectations, with Opportunity covering nearly 30 miles on the Martian surface.
