Spectrum Aborts at T-3 | Canada Loses Its Moon Rover | Triton Tilted Neptune

Episode Summary Today's episode opens with a brief update on the Isar Aerospace Spectrum rocket, which aborted at T-3 seconds on March 25 — just before engine ignition — with no new launch date yet announced. The main stories cover Canada's cancellation of its first lunar rover mission; the century-old mystery of Gamma Cassiopeiae's anomalous X-ray emissions finally solved by the XRISM space telescope; new research suggesting Neptune's axial tilt may have been caused by its captured moon Triton; NASA's Dragonfly rotorcraft entering full integration and testing ahead of a 2028 launch to Saturn's moon Titan; Russia returning to orbit from Baikonur Cosmodrome following last November's structural collapse; and the new SPHEREx telescope detecting a bipolar hydrogen shell around the remnant of Nova Persei 1901.
