Astronomy Daily — S05E141 | Wednesday 15 July 2026 Anna and Avery bring you the biggest space and astronomy news of the day: Starship Flight 13 is cleared for Thursday after the FAA closes its Flight 12 investigation and SpaceX reveals exactly what went wrong; NASA astronaut Anil Menon rides a Soyuz to the ISS on his first flight; astronomers finally find the first of Omega Centauri’s 10,000 "missing" black holes; the first-ever medical X-rays taken in space are published; four white dwarfs are found hiding within 65 light-years of Earth; and a new-moon dark-sky window opens with Comet 10P/Tempel 2 on the rise. In this episode • Starship Flight 13 — FAA closes the Flight 12 mishap investigation (July 13); root causes revealed: hot-staging ignition sequence caused a 90° booster orientation error, five Raptors failed to relight, alarm settings shut engines down early. Launch window opens Thursday July 16, 6:45pm EDT (Friday 8:45am AEST) with the first 20 functional Starlink V3 satellites and an in-space Raptor relight. • Soyuz MS-29 — NASA’s Anil Menon with cosmonauts Pyotr Dubrov and Anna Kikina launched from Baikonur July 14, docking three hours later for an eight-month stay. Menon and wife Anna Menon (Polaris Dawn) become a two-astronaut household; NASA Administrator Jared Isaacman attended in person. • Omega Centauri’s first stellar-mass black hole — oMEGACat BH-2, found via astrometry in 20+ years of Hubble data plus Webb observations (ApJL, July 13). Lower-than-expected mass; its companion star’s 94-year orbit makes it the longest-period black hole binary known. The cluster is naked-eye visible in southern winter skies right now. • First medical X-rays in space — RSNA publishes results from the Fram2 Crew Dragon mission: crew with 4 hours’ training produced diagnostic-quality X-rays in orbit, opening the door to space radiology and non-destructive hardware testing on Moon and Mars missions. • Four hidden white dwarfs — Warwick/Colorado Boulder team unmasks four white dwarfs within 65 light-years using Hubble near-UV spectroscopy (MNRAS). G 203-47, ~25 light-years away, is now the ninth-closest known white dwarf and closes a 27-year-old wobble mystery. • Skywatch — New Moon (July 14) dark skies, Milky Way core season for the Southern Hemisphere, Comet 10P/Tempel 2 at magnitude 7–8 brightening toward early-August perihelion, and Mars near Aldebaran pre-dawn.
