NASA is proposing a cheaper and quicker method to retrieve rocks and soil from Mars after the original plan's cost ballooned to $11 billion. Administrator Bill Nelson announced a revised scenario, aiming to bring back samples from Mars in the 2030s. The agency is considering options in the $7 billion range, including potential collaboration with commercial partners. The decision on the new plan is expected next year, with the goal of analyzing samples for signs of ancient Martian life. Incoming administration will determine the best approach to retrieve the Mars samples, with funding being a crucial factor in the mission's success.
