    Why is Mars red? A new clue to the history of habitability in Martian dust

    Play Episode Listen Later Apr 9, 2025 54:56


    For decades, scientists hypothesized that Mars’ reddish color came from hematite, an iron oxide thought to have formed through dry oxidation after Mars lost its water. But new research suggests the story is more complex—and more watery—than we once imagined. In this episode, planetary scientist Adomas (Adam) Valantinas from Brown University joins host Sarah Al-Ahmed to discuss his team’s discovery that Mars’ iconic red dust is likely dominated not by hematite but by a hydrated mineral called ferrihydrite. This subtle but significant shift in understanding could reshape what we know about Mars’ climate history and its potential for past habitability. Then, Sarah and Bruce Betts, Planetary Society chief scientist, revisit one of the most famous Martian discoveries: Opportunity’s hematite-rich “blueberries,” which also told a compelling story about water on the Red Planet.

    For over half a century, space advocates and presidents alike have tried to recreate the JFK moment of calling on the country to send a man to Moon — but is this a mistake? The classic book Spaceflight and the Myth of Presidential Leadership argued that it is, and by focusing on presidential power alone advocates set up these initiatives to fail. However, in the decades since its publication, presidential authority has dramatically expanded. In this episode, we examine this tension: Did the success of Apollo create a false expectation about the role of presidential leadership in spaceflight?

    Norm Augustine, the distinguished aerospace industry veteran behind numerous influential studies, joins the show to discuss “NASA at a Crossroads,” the new report that raises alarm bells for NASA's workforce, infrastructure, and technology capabilities. Augustine, who chaired an expert committee of the National Academies of Sciences, Engineering, and Medicine, came to the conclusion that NASA is on an unsustainable path, and has underinvested in its enabling workforce and physical infrastructure for decades.  The solutions put forth by this report committee will require years of effort from NASA, Congress, and subsequent presidential administrations. Which path NASA decides to take, however, may not be known for years to come.
