Shifting NASA's Mars Strategy

NASA rethinks approach to Mars exploration, Nature

"This broadening context prompted Watzin to propose the new way of operating Mars missions. "I'm not trying to fix something that's broken," he said. "I'm trying to open the door to a larger level of collaboration and participation than we have today, looking to the fact that we're going to have a larger pool of stakeholders involved in our missions." Under the new, facility-based approach, scientists would propose investigations using one or more instruments on a future spacecraft. NASA would award observing time to specific proposals, much as telescope allocation committees parcel out time on their mountaintops. This would be different than the current approach where instruments are proposed, built and operated by individual teams of scientists."
