Astronomy Daily · S05E163 · “The Long Way Home” · Monday 10 August 2026. Sources verified against primary / institutional outlets. 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. Cao et al., AGU Advances; surfaced via an Eos research spotlight this week. (Framed as newly-spotlighted rather than newly-published.) • Sources: AGU Advances (Cao et al.); Eos research spotlight; phys.org (7 Aug). 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 under a new Moon — excellent for the Northern Hemisp

Astronomy Daily · S05E161 · “The Colour of Empty Space” · Friday 7 August 2026. Hosts: Anna & Avery. astronomydaily.io · @AstroDailyPod ① Vacuum birefringence: reading a magnetar ● NASA’s IXPE, with NICER and the Parkes/Murriyang radio telescope (NSW), measured the polarised X-rays of magnetar 1E 1547.0−5408. ● Result: soft X-ray polarisation ~65% at 2 keV, rising to nearly 80% at some rotation phases — the strongest signal yet of vacuum birefringence, a QED effect predicted by Heisenberg in 1936. ● The team calls it the “most definitive signal to date,” not a confirmed detection; an April 2026 analysis disputes it under different geometry. Co-leads: Rachael Stewart; Hoa Dinh Thi (Rice); with Marcus Lower (Swinburne). ● Source: Stewart et al., Nature, 5 Aug 2026 (DOI 10.1038/s41586-026-10859-z); NASA IXPE release. ② Gateway HALO hardware → Lunar Infrastructure Demos ● NASA and Northrop Grumman are repurposing the HALO module’s power, data and avionics into three surface missions — LID-1, LID-2, LID-3. ● Goal: “survive-the-night” power and thermal tech for the lunar South Pole, where night lasts ~14 Earth days and temperatures plunge below −200 °C. ● Part of a wider Moon-base update in which four commercial landers reached final qualification testing at once. ● Source: NASA & Northrop Grumman releases, 4 Aug 2026; Spaceflight Now. ③ New Glenn: the cause is a valve ● Blue Origin traced the 28 May New Glenn booster explosion (during a pad hot-fire at Cape Canaveral) to the main oxygen valve on one of the seven BE-4 engines. ● Fix: small, retrofittable valve modifications; return to flight still targeted by year’s end. The BE-4 also powers ULA’s Vulcan. ● Source: Blue Origin CEO Dave Limp, 5 Aug 2026; SpaceNews. ④ LINK’s de-spin: the fight to save Swift ● Katalyst Space’s LINK robot — tasked with boosting NASA’s ageing Swift observatory before re-entry — hit a multi-axis tumble when two of three reaction wheels failed. ● Using gimballed electric-propulsion thrusters, the team cut the spin from ~9°/s to ~1.47°/s on under 100 g of propellant. A flight-software update is next; rendezvous slips to ~end of August. ● Source: NASA Swift blog, 6 Aug 2026; Katalyst mission updates. ⑤ Skywatch: eclipse + Perseids ● 12 Aug total solar eclipse — totality across Greenland, Iceland, northern Spain; afternoon partial for eastern Canada and the NE United States (10% only NE of the NYC–Rochester line; ~50% in Atlantic Canada). NASA live from 1:15 pm EDT. ● Perseid peak the night of 12–13 Aug under a New Moon — up to ~100/hr from dark rural sites. ● Southern Hemisphere: eclipse not visible; Perseids barely clear the horizon. Sydney: pre-dawn planet line-up + Venus + winter Milky Way. ● EYE SAFETY: use only ISO 12312-2 eclipse glasses for every partial phase; never combine them with a camera, telescope or binoculars.

In this episode: a Falcon 9 upper stage confirmed to have struck the Moon; a live ISS spacewalk; supernova SN 2026gzf caught at first light; SpaceX Crew-13 previewed; and a both-hemispheres guide to the 12 August eclipse and Perseids. FALCON 9 LUNAR IMPACT (LEAD) ● Spent upper stage 2025-010D struck near Einstein Crater (~19.4°N, 93.3°W) at ~06:35 UTC, 5 Aug 2026 — matching Bill Gray / Project Pluto predictions. ● ESO’s Very Large Telescope (Paranal) detected sodium and lithium in the impact plume for ~5–10 minutes — sodium from lunar soil, lithium likely from the rocket. ● NASA’s Lunar Reconnaissance Orbiter holds a pre-impact baseline and will image the fresh crater, giving a rare before-and-after dataset to validate hollow-body impact models for future landers. ● Origin: Falcon 9 launched 15 Jan 2025 with Firefly Blue Ghost 1 and ispace Resilience; the stage was left adrift and returned unplanned via solar activity and gravity. ● Sources: NASA; ESO / VLT; CNN; Project Pluto (projectpluto.com); Fernando et al., arXiv:2607.14625. ISS SPACEWALK — U.S. EVA 96 ● NASA’s Jessica Meir (Expedition 75 commander) and Anil Menon; ~6.5 h EVA beginning ~08:35 EDT, 6 Aug; live on NASA+. ● Task: reconfigure the 3B power channel to accept a seventh roll-out solar array later in 2026 — part of station upkeep ahead of the planned 2030 deorbit. ● Menon’s first spacewalk; two further EVAs scheduled 13 and 25 Aug. ● Sources: NASA / NASA+ ; NASA ISS blog. SUPERNOVA SN 2026GZF ● X-ray “shock breakout” (EP260321a) detected by China’s Einstein Probe on 21 Mar 2026 from a galaxy ~500 million light-years away; follow-up revealed a broad-lined Type Ic supernova. ● Unusually, no gamma-ray burst and no lasting relativistic jet — and the faintest shock breakout yet linked to this class; a possible missing link between ordinary and GRB-producing supernovae. ● Follow-up used NSF NOIRLab facilities including DECam and the Vera C. Rubin Observatory. Two teams: O’Connor et al. (CMU) and Rastinejad et al. (UMD), in ApJL. ● Sources: NSF NOIRLab; Carnegie Mellon University; The Astrophysical Journal Letters. SPACEX CREW-13 ● Targeting NET 12 Sep 2026 aboard Crew Dragon Grace from SLC-40, Cape Canaveral. ● Crew: Jessica Watkins (NASA, cmdr — first NASA astronaut to fly Dragon twice), Luke Delaney (NASA, pilot), Joshua Kutryk (CSA), Sergey Teteryatnikov (Roscosmos). 180-day stay; moved up from November. ● Sources: NASA; SpaceX; Houston Public Media. SKYWATCH — 12 AUGUST & BEYOND ● Total solar eclipse 12 Aug: totality across E Greenland, W Iceland, N Spain and NE Portugal (max 2m18s). Partial across northern US (Alaska–N Carolina), most of Canada, much of Europe and NW Africa. NASA livestream from 1:15 pm EDT. ● US partial highlights: Presque Isle ME ~29% (contiguous-US max); NYC ~9% from ~1:07 pm EDT; Boston ~16%; Toronto ~8%; Montreal ~18%; St John’s ~53%. ● Perseids peak 12–13 Aug under a new Moon (northern-favoured, up to ~100/hr from dark northern sites). ● Southern Hemisphere: pre-dawn planet parade (Saturn best, near opposition; Mars, Mercury, Uranus, Neptune), brilliant Venus in the evening west, and the winter Milky Way high overhead. ● Look-ahead: deep partial lunar eclipse 28 Aug (96% umbral), favouring the Americas. ● SAFETY: use only ISO 12312-2 certified eclipse glasses / solar filters during any partial phase. ● Sources: NASA; ESA; Sky & Telescope; BBC Sky at Night; EarthSky; timeanddate.com; The Planetary Society.

Astronomy Daily S05E159 — Wednesday, 5 August 2026. In this episode: a power-saving “Big Bang” keeps Voyager 2 doing science, direct-to-phone satellites reach orbit, Curiosity finds a vast honeycomb field on its 14th Martian anniversary, and NASA’s Aspera prepares to hunt the universe’s missing gas. ① Voyager 2’s “Big Bang” power save • JPL engineers freed up power by simultaneously switching off certain devices and substituting lower-power alternatives, while keeping the spacecraft warm enough to operate. • The Voyagers run on radioisotope thermoelectric generators (RTGs) and lose ~4 watts per year as their plutonium decays; after nearly 50 years, power margins are razor-thin. • The move keeps three instruments — magnetometer, plasma wave subsystem and cosmic ray subsystem — running at least a year longer; the same swap is planned for Voyager 1. • Voyager 2 crossed the heliopause in Nov 2018 and is now 13 billion miles (21 billion km) from Earth; its southerly path means it is commanded via the Canberra Deep Space Network dish. Source: NASA/JPL Voyager blog, 4 Aug 2026 · science.nasa.gov/blogs/voyager ② AST SpaceMobile BlueBird 11–13 • Three next-generation direct-to-smartphone satellites launched on a Falcon 9 from Cape Canaveral (liftoff targeted 3:42 a.m. EDT, 5 Aug; backup 5:10 a.m.). • Their phased-array antennas span ~2,400 sq ft — the largest commercial arrays ever deployed in low Earth orbit — and connect to standard, unmodified phones. • They deliver nearly double the peak download speed of the first-generation BlueBirds (which hit ~98.9 Mbps to a phone); the company targets beta service later in 2026. Source: AST SpaceMobile / Space.com, Aug 2026 · confirm deployment before publish ③ Curiosity’s “sea of polygons” + 14 years • Curiosity found its largest-ever field of honeycomb-like polygonal fractures (each ~4–8 cm across) in a valley nicknamed “Valle Grande” on Mount Sharp. • The 360° panorama was captured on 19–20 June from 340 images; the polygons wrap around a ~6 m butte nicknamed “Miraflores.” • Such patterns point to ancient water — drying mud, wet–dry cycles, or compaction — consistent with lakes and streams once present on Mount Sharp’s foothills. • Today, 5 August, is Curiosity’s 14th landing anniversary (landed 5 Aug 2012). Source: NASA/JPL, announced ~29 Jul 2026 · jpl.nasa.gov ④ NASA’s Aspera (mission preview) • Aspera is a shoebox-sized NASA Pioneers smallsat launching NET 15 Aug on a Rocket Lab Electron from Mahia, New Zealand. • It is the first NASA astrophysics mission to map the circumgalactic medium — hot gas around galaxies — in ultraviolet light, tracing the “missing baryons.” • Led by Carlos Vargas at the University of Arizona, one of the youngest principal investigators in NASA history. Source: NASA Pioneers / Rocket Lab, 2026 · rocketlabcorp.com ⑤ Skywatch • Tonight (5 Aug): Last Quarter Moon; Mars forms a triangle with Elnath and cluster M35 (binoculars help). • 12 Aug: total solar eclipse (Arctic–Greenland–Iceland–northern Spain; partial for parts of the US) — not visible from Australia; use ISO 12312-2 eclipse glasses. • 12–13 Aug: Perseid peak under a New Moon (NH-favoured); plus a six-planet pre-dawn alignment. • SH targets: eta-Eridanids peak 7 Aug; Sagittarius star fields; deep partial lunar eclipse 27–28 Aug (Americas + parts of Europe/Africa).

S05E158 — “The Crater Makers” · Tuesday 4 August 2026. Four stories on cosmic impacts — and a new map of the X-ray sky — plus a both-hemispheres skywatch. ① A dead Falcon 9 is about to crater the Moon ● A spent SpaceX Falcon 9 upper stage (catalogued 2025-010D) is predicted to strike the Moon near Einstein Crater on 5 Aug 2026 at ~06:35 UTC — the second documented uncontrolled rocket impact on the Moon. ● The stage launched Firefly’s Blue Ghost and ispace’s Resilience landers in Jan 2025, then was stranded in a chaotic Earth orbit for ~18 months. Impact speed ~2.4 km/s (~5,400 mph); expected crater ~17–27 m across. ● Prediction by Bill Gray (Project Pluto). NASA’s LRO can image the site before and after; a ~two-dozen-author campaign is coordinating observers to chase the ejecta plume. ● Governance angle: no international framework governs cislunar debris — a growing hazard as lunar traffic increases (callback to E154’s distant-retrograde-orbit debris study). Sources: Space.com / Forbes / Reuters (Cris Tolomia) — impact preview, 31 Jul–3 Aug 2026 · Project Pluto (Bill Gray) — 2025-010D impact page · ZME Science — impact timing, 3 Aug 2026 ② Neptune’s inner moons: shrapnel of a shattered world ● JWST NIRSpec spectroscopy of Neptune’s inner moons Larissa, Galatea and Proteus (Caltech; lead author Ryleigh Davis, Mike Brown’s group) detected magnesium-rich phyllosilicates — clay minerals that require liquid water and had never been seen beyond Jupiter. ● The clays imply the material came from much larger, water-bearing worlds — evidence that Neptune’s original regular moon system was destroyed when Triton (a captured Kuiper Belt object) arrived. ● Proteus, the largest of the three, lacks the clays — possibly re-heated and reprocessed after re-forming, hiding its history. Sources: Davis et al., Science Advances, 29 July 2026 · Caltech / phys.org press coverage, 29 Jul–3 Aug 2026 · Space.com (Charles Q. Choi), 3 Aug 2026 ③ “Charbroiled within hours”: impact dust and the dinosaurs ● New modelling (Brandon Johnson et al., Purdue) argues ultrafine impact dust from Chicxulub acted as an insulating blanket, raising surface heating ~3.5× above the spherule-only estimate — enough to ignite global wildfires and kill exposed animals within hours. ● The same dust then blocked sunlight for years — so the model adds a ferocious opening act to the established “impact winter,” rather than replacing it. Sheltering underground or underwater aided survival. ● Caveat: the strongest physical wildfire evidence is so far confined to North America (per UCL’s Alfio Chiarenza, not involved in the study); a truly global fire record remains unconfirmed. Sources: Johnson, Johnson, Wakita & Robertson, JGR: Biogeosciences, 2026 · Popular Science / Space.com / ZME Science, 28 Jul–2 Aug 2026 ④ eROSITA DR2 — the X-ray sky doubles ● The eROSITA telescope (SRG mission) released its second data set (DR2) on 31 July 2026: ~1.9 million pointlike and ~64,000 extended X-ray sources from the first three all-sky scans — nearly doubling the previously released eROSITA catalogue. ● For scale: ROSAT catalogued ~130,000 sources in the 1990s and was the benchmark for 30 years.
