Planetary scientist Michael A’Hearn passed away on Monday, May 29, leaving a remarkable legacy in cometary science—but even more importantly in the careers of many younger scientists who flourished with his encouragement and mentorship.
In another dynamic demonstration of what can be achieved when a team works together, Opportunity cruised to the top of Perseverance Valley, shot the moon, and drove into her 160th month of surface operations in May.
