## Resource

Today's episode — S05E179 , Friday August 28, 2026: Feature story: US startup Reflect Orbital has FCC approval for Eärendil-1, a demonstration satellite carrying a 60-foot mirror, the first step toward a planned constellation of 50,000-plus orbital mirrors beaming reflected sunlight to Earth on demand. A new peer-reviewed study (Kocifaj, Bakos and Kundracik, accepted at The Astrophysical Journal Letters) finds a full-scale, 174-foot operational mirror would appear about 40 times brighter than the full Moon to anyone standing in its roughly 3.4-mile beam, with measurable sky-glow extending 20-34 km further — astronomer Gáspár Bakos says it would be "worse than big cities like London," warning "you would not see any stars if you were in the beam." The rest of the news: Starship update: Ship 40 — the Flight 13 upper stage that survived an intact splashdown on July 24 — has been loaded onto a heavy-lift transport vessel off Christmas Island and is now heading home to Starbase, Texas, a journey expected to take several months. Meanwhile Flight 14 has quietly slipped to no-earlier-than September 15, per internal SpaceX/FAA planning documents, with Booster 21's static fire testing now the pacing item. A hot, watery world on borrowed time: astronomers led by Sylvain Breton (INAF) have characterised HD 176071 b, an exoplanet 335 light-years away that's roughly 50% water by mass, orbiting so close to its star (a 14-hour year) that it's expected to eventually be consumed by tidal forces. Found via a reflected-light technique applied to archival Kepler data. Roman Space Telescope: two days from its Sunday, August 30 launch (7:26am ET, Falcon Heavy), with today's Launch Readiness Review still underway as we record. We trace the mission's near-cancellation in leaked 2025 budget docu…
