NASA's interim administrator, Sean Duffy, addressed reporters regarding new evidence of potential past microbial life on Mars discovered by the Perseverance rover. The discussion was largely dominated by questions about the future of the $8-11 billion Mars Sample Return mission, currently on hold. Duffy stated the mission's review is ongoing, considering budget, timing, and technological advancements. He acknowledged President Trump's previous call for cancellation but emphasized continued Mars exploration. Potential paths forward include commercial partnerships, incentivized prizes, or integrating sample return into a future human mission. A final decision remains pending.
