Starship “lost at sea” (Flight 13) • Flight 13 launched 24 July 2026 from Starbase, South Texas; the upper stage (“Ship,” Ship 40, ~52 m) made the softest Starship water landing yet in the Indian Ocean off Western Australia — and, in a program first, survived intact and afloat. • SpaceX had not planned to recover it. Musk confirmed the salvage attempt on 28 July (“We’re sending a ship out to recover Starship”); recovery ship Go Australis was joined by Norwegian tugs Normand Ranger and Skimmer Tide, with a tow line to the nose. • On 7 August, Musk said recovery is “not looking good right now” in rough seas — but the team had already obtained close-up photos of critical heat-shield and engine regions for future upgrades. A saltwater-soaked Ship was never going to be reflown. • Heat shield: on SpaceX’s first quarterly earnings call (4 August) Musk said he’d “consider the heat-shield problem solved,” long the biggest hurdle to full reuse. • The flight also deployed 20 next-gen Starlink V3 satellites; the Super Heavy booster had engine trouble and was lost in the Gulf of Mexico. Stacked, Starship stands ~124 m. Flight 14 is targeted for late August — its first attempt at operational orbit with production Starlink. • Sources: SpaceX / @elonmusk on X (7 Aug); Space.com (Mike Wall, 7 Aug); CNN (3 Aug). Landspace Zhuque-3, second landing attempt • Landspace (private, Beijing, founded 2015) targets liftoff ~7:45 p.m. EDT Mon 10 Aug (23:45 UTC / ≈9:45 a.m. AEST Tue 11 Aug) from Jiuquan, aiming for a propulsive first-stage recovery on legs (Falcon 9-style), landing downrange in Gansu. • The methalox, stainless-steel Zhuque-3 (~66 m) is broadly a Falcon 9 rival. Its Dec 2025 maiden flight reached orbit but the first stage failed its landing burn and crashed. • Accuracy note: this is China’s fourth orbital-class recovery attempt. A Long March 10B already landed via net-capture on 10 July (China became the 2nd nation to land an orbital booster) — so tonight would make Landspace the first Chinese company to attempt a propulsive/landing-legs recovery, not “China’s first.” • Sources: Space.com (7 Aug); Yahoo/Space (7 Aug); launch trackers (NOTAM-based). Uranus’s “breathing” bow shock • New multifluid-MHD modelling shows Uranus’s bow shock expands and contracts over a single ~17-hour Uranian day — driven by the planet’s own extreme rotation and tilted, offset magnetic field, not by changes in the solar wind. • The model is constrained by Voyager 2’s 1986 flyby — still the only direct measurements ever taken inside the Uranian system (a nice callback to E159’s Voyager 2 “Big Bang” lead). • Implications for future ice-giant missions and for the many ice-giant exoplanets now being found.

Total solar eclipse — 12 August 2026 • The only total solar eclipse of 2026. Unusual over-the-pole path: Arctic Siberia → eastern Greenland → western Iceland → northern Spain (clipping NE Portugal) → the Balearics at sunset. • Greatest eclipse ≈17:46 UTC; max totality 2 min 18 s just off Iceland’s west coast, with the Sun only ~26° high. Iceland’s first total eclipse since 1954 (Reykjavik’s first in 593 years); Spain’s first since 1905. • North America sees a partial across the northern tier (Alaska to North Carolina) and most of Canada — deepest in the far north, a shallow bite (<10%) from the US Northeast, late morning to early afternoon local. NASA livestream from 1:15 p.m. EDT at nasa.gov/live. • Not visible from the Southern Hemisphere. Sources: NASA eclipse pages; national eclipse guides. Skywatch — both hemispheres • Perseids peak the night of 12–13 August...
