Major Shira Diamond, a decorated test pilot and aerospace systems expert, serves as the Exo-Vehicle Operations Specialist, overseeing all Martian surface transport and EVA mobility systems. With over 3,000 flight hours across atmospheric and space-rated vehicles, Shira brings a rare blend of precision piloting and mechanical intuition. She is also the primary operator of the Gringolet Rover, the crew’s heavy-lift, long-range exploration vehicle designed for deep-field science and logistics. Prior to the mission, she led prototype field trials for next-gen pressurized rovers in extreme Earth analogs, including Antarctica and the Atacama Desert. Her role is critical for ensuring safe navigation, maintenance, and tactical deployment of mobile assets across the Martian terrain. Shira’s fearless spirit and mission-first mindset inspire confidence both in and out of the rover.
