On Wednesday, the Senate Committee on Commerce, Science and Transportation heard testimony from Jared Isaacman, President Trump’s nominee to lead NASA. During the confirmation hearing, Isaacman indicated a priority of sending humans to Mars—while maintaining the agency’s plans to return people to the lunar surface.

In response to a question from Senator Ted Cruz, Isaacman said “I don’t think we have to make any tough trades here, Senator. I think if we can concentrate our resources at the world’s greatest space agency, we don’t have to make a binary decision of moon versus Mars, or moon has to come first versus Mars.” Senators questioned how a strategy involving both options would be possible under current funding levels, and stressed that a bipartisan law had codified the current approach of targeting the moon first, then Mars.

The fate of the Artemis lunar exploration program has faced questions in the new administration. In his inaugural address, President Trump expressed a desire to send astronauts to Mars, but didn’t mention the moon. Elon Musk, head of SpaceX and a favored advisor to the president, is in favor of prioritizing crewed Mars missions ahead of lunar programs. Under questioning, Isaacman repeatedly refused to say directly whether Musk had been present for his job interview with the President.

Isaacman, a billionaire entrepreneur and businessman, is a nontraditional choice to lead the space agency. While he is an avid pilot and has been to space twice on commercial space missions, including the first private spacewalk, he does not come from a NASA, science, or government background. His nomination comes at a time when government agencies are facing steep cuts and restructuring. Early in March, NASA announced that it was eliminating the Office of the Chief Scientist, along with offices advising the agency on technology, strategy, and coordinating its diversity, equity, inclusion, and accessibility work. In late March, a DOGE post said that $420 million in NASA grants had been terminated. A vote on Isaacman’ nomination would not happen until later in this month.

Host Flora Lichtman talks with Senior Producer Charles Bergquist about the nomination and the path ahead for NASA. They also talk about other stories from the week in science, including the controversy over claims of a “de-extincted” dire wolf, advances in rapid bird flu sensors, how tropical trees can monitor mercury pollution from illegal gold mining, the detailed physics of a cup of pour-over coffee, and how your wandering mind might actually help you learn.
