Planetary Radio: Space Exploration, Astronomy and... ·

2023/11/03

NASA’s Mars Sample Return mission was supposed to be lean, fast, and focused — no extra science instruments, no dedicated communications systems, and launching in 2026. But the effort has foundered under its own complexity and mismanagement. MSR’s total cost is likely to double to $10 billion or more and not launch until 2030 at the earliest. This month’s guest, Orlando Figueroa, chaired an independent review board which recently evaluated this project and identified management failures, unexpected
