The Artemis II mission's $4.5 billion budget has sparked scrutiny over opportunity costs, with critics urging NASA to redirect funds toward Earth observation satellites or clean energy initiatives. Patel noted that SpaceX's Starship program, which aims to cut launch costs by 50%, could reshape the economics of human spaceflight. Meanwhile, Dr. Grinspoon pointed to astrobiology as a unifying goal, suggesting that Artemis II's focus on lunar resource extraction might pave the way for in-situ resource utilization on Mars.

The debate also touched on regulatory challenges, such as space traffic management and international treaties, which could stall progress. Ultimately, the panelists urged a collaborative approach to balance innovation with practicality.
