Astronomy Daily · S05E164 “Eclipse Eve” · Tuesday 11 August 2026. Sources are primary/agency where possible; aggregator dates were checked against originals. In this episode • LEAD — The 12 August total solar eclipse: the only total eclipse of 2026 and the first over mainland Europe since 1999. Totality arcs from Siberia over the North Pole to eastern Greenland, western Iceland, northern Spain and a sliver of Portugal; maximum totality ~2 min 18 s. Partial for much of North America near sunset; not visible from Australia. ESA livestreams from the Javalambre Observatory, Spain. • MIDDLE 1 — A state CASC Long March 7A exploded ~85 seconds after lifting off from Wenchang on 10 August, a total loss (payload reported as the Zhongxing-4B communications satellite). Separately, Landspace’s private Zhuque-3 was on the same-night manifest from Jiuquan for its second propulsive landing-legs recovery attempt — outcome unconfirmed at recording. China’s first orbital-booster landing (net-capture, Long March 10B) already succeeded on 10 July. • MIDDLE 2 — The Perseids peak overnight 12–13 August under a New Moon — the darkest conditions in roughly two decades. Parent comet 109P/Swift-Tuttle. Realistic ~30–50 meteors/hr from dark sites (nominal ~100), with a slim chance of a dust-trail boost; the next confidently forecast outburst is 2028. • MIDDLE 3 — Japan’s H3 launched Michibiki No. 7 (QZS-7) from Tanegashima, bringing the Quasi-Zenith Satellite System up to the strength Japan needs to run it as a standalone service — a regional navigation layer that keeps a satellite near the zenith over Japan/Asia-Pacific, reinforcing GPS and building navigation resilience. The satellite also hosts a US Space Force space-surveillance sensor (SACHI). • CLOSER — Both-hemispheres skywatch: eclipse viewing times (totality window ~
