"The mission to Pluto was meant to complete the exploration of the planets in the Solar System. But scientists reclassified Pluto from a planet to a "dwarf planet" shortly after New Horizons launched in 2006. That reclassification split the space science community. But Stern has a clear opinion about Pluto's demotion: "It's bullsh*t," he told Tech Insider (and said we could quote him on that)."
Keith's note: (Sigh) once again this NASA principal investigator sets a new low standard for public discourse. At a time when NASA is focusing on education and inspiring the next generation of space explorers I find it rather odd that a NASA PI, speaking in an official capacity, would be putting forth such a crude example of how NASA scientists conduct themselves in the public's eye - and that he does so over such a tired and worn-out issue. Pluto is Pluto. Get over it.
