About

A. Kusack is a key figure in planetary robotics, best known for their instrumental role in the Mars 2007 Phoenix Lander mission. Their primary research focuses on the design and operation of robotic sampling systems for extraterrestrial environments, particularly for acquiring and handling icy soil. Kusack’s major contribution is the development of the Phoenix Robotic Arm and its Icy Soil Acquisition Device (ISAD), a groundbreaking system capable of digging, scraping, and rasping Martian permafrost to deliver pristine samples to onboard analytical instruments. This work, detailed in their most-cited paper (64 citations), directly enabled the first-ever in-situ analysis of water ice on Mars, confirming its presence and providing critical data on the planet’s hydrologic history. Kusack’s engineering achievements overcame extreme challenges—operating at cryogenic temperatures and through a thin, rocky regolith—demonstrating a robust design that has influenced subsequent sample-return concepts. Their contributions remain foundational for future missions targeting volatile-rich terrains, such as the Mars Ice Mapper or lunar polar landers, cementing Kusack’s legacy in the advancement of planetary in-situ resource utilization.
