Swapna Kumbar , Bengaluru - NASA Administrator Jared Isaacman made headlines during a US Senate Appropriations Committee hearing by passionately calling for Pluto's reinstatement as a planet, declaring himself very much in the camp of 'make Pluto a planet again. Responding to Kansas Senator Jerry Moran whose state claims Pluto discoverer Clyde Tombaugh Isaacman revealed NASA researchers are preparing scientific papers to reopen the 2006 International Astronomical Union (IAU) debate that downgraded Pluto to dwarf planet status.

The billionaire SpaceX astronaut and Trump appointee argued Pluto's unique characteristics heart shaped nitrogen ice plains, dynamic geology revealed by New Horizons, and Clyde Tombaugh's farmboy to astronomer legacy warrant planetary recognition. Isaacman highlighted post-2006 discoveries showing Pluto's complexity rivals inner planets, challenging IAU criteria that it hasn't cleared its orbital neighborhood amid Kuiper Belt objects. NASA studies aim to escalate through scientific channels, potentially influencing IAU's next planetary definition review. This revives a 20 year controversy: Pluto's 1930 discovery as the solar system's ninth planet lasted until IAU's Prague meeting redefined planets, sparking protests from planetary scientists and public campaigns like My Very Educated Mother Just Served Us Noodles mnemonic rewrites. Isaacman's position aligns with figures like Elon Musk and former NASA chief Jim Bridenstine, while IAU defenders maintain dwarf planet status reflects Pluto's transitional role between rocky worlds and Kuiper Belt populations.

Isaacman's Senate plea transforms Pluto's demotion from astronomy footnote to political cause célèbre, leveraging NASA's platform to challenge scientific orthodoxy. Success could rewrite textbooks and boost public astronomy engagement, but faces entrenched IAU resistance unless mounting evidence forces planetary redefinition, making Pluto the solar system's ninth world once more.
