ISAM in Defense Strategy, with Patsy Klein (Falcon Research) and Dennis Wille (Astroscale U.S.)

This week on Pathfinder, we’re excited to bring you a special one-off episode, made possible by Astroscale U.S., the Denver-based subsidiary of Astroscale, a global provider of on-orbit servicing solutions. This episode dives into the DoD’s push to integrate commercial in-space servicing, assembly, and manufacturing (ISAM) capabilities to enhance flexibility, resilience, and sustainability in military space operations.

Joining the discussion are retired Colonel Dennis Wille, Senior Director of Business Development for National Security at Astroscale US, and John “Patsy” Klein, Senior Fellow in Strategy at Falcon Research and a leading expert in space policy and strategy. Together, we unpack how ISAM technologies are transforming space operations and advancing U.S. leadership in the domain.

This episode covers:

• The DoD’s commercial space integration strategy and ISAM’s role in enhancing operational resilience
• The challenges and opportunities of managing space debris and enabling active debris removal
• How ISAM capabilities like refueling, repair, and inspection are reshaping spacecraft lifecycles
• The critical role of commercial partnerships in supporting national security objectives
• The future of space operations and the technologies poised to drive innovation

And much, much more…
