Astronomy Daily S05E148 — "Far Side" Thursday 23 July 2026 Starship gets a second shot at Flight 13 — with a schedule caveat worth knowing about. The first far-side lunar samples reveal that Earth has been quietly shielding the side of the Moon that faces us. Astronomers debate whether the lunar far side should be closed to industry. The Milky Way's only helium nova finally steps out from behind twenty-five years of dust. And the case that our entire galaxy once turned over. Plus a skywatch closer with a straightforward piece of advice about the Delta Aquariids: do not wait for the peak.





In this episode Starship Flight 13 ● Window opens 6:45pm EDT / 2245 GMT Thursday 23 July — 8:45am AEST and 10:45am NZST Friday 24 July. ● Schedule is not locked: Starbase road and beach closure notices point to further Pad 2 testing. ● The 16 July attempt aborted at T-0 when four of 33 Raptors missed start parameters; the limit is three. ● Two Raptors were removed and replaced before this attempt. ● First-ever Starship deployment of V3 Starlink satellites — 20 of them. ● Super Heavy splashes down in the Gulf at ~7 minutes; Ship targets the Indian Ocean off Western Australia at ~65 minutes. No catch attempts. Chang'e-6 and the solar wind ● Published in Nature Geoscience by a team at the Chinese Academy of Sciences' Institute of Geology and Geophysics. ● Based on 1,935 grams of regolith returned from the South Pole–Aitken basin on the lunar far side. ● First direct laboratory comparison of solar wind implantation between the near and far sides. ● Far-side soil records faster, deeper-penetrating particles; the neon isotope ratio sits below every near-side sample measured. ● About a quarter of the solar wind exposure at the Chang'e-5 near-side site involved wind decelerated by Earth's magnetosphere. The far-side site shows none. ● Opens the possibility of using lunar noble gases as a fossil record of Earth's magnetic field over deep time. The far side debate — NAM 2026 ● Held Tuesday 21 July at the RAS National Astronomy Meeting, University of Birmingham. Convened by Prof Martin Ward. ● For the motion: Prof Joe Silk (Johns Hopkins) and Dr Jonathan McDowell (Durham Space Research Centre). ● Against: Dr Nikita Chiu (Durham) and Dr Manuel Salvoldi (aerospace engineer and educator). ● For: the far side is the only radio-quiet site near Earth — critical for detecting the cosmic dark ages, and an exceptional platform for gravitational wave detection. ● Against: commercial investment is what makes lunar exploration sustainable, and governance can let science and industry coexist. ● Audience support for the motion rose from 68% to 76% across the debate. V445 Puppis ● Presented at NAM 2026 by John Mills, University of Warwick. ● The only confirmed helium nova in the Milky Way. Erupted in late 2000, then vanished behind its own dust for over twenty years. ● Now confirmed as a white dwarf accreting from a rare stripped helium star — only a few thousand such stars are thought to exist in the entire galaxy. ● Orbital period of 3.7 days, roughly double previous estimates. Mass transfer has resumed. ● Unexplained high-speed "bullets" of possibly oxygen-rich gas travelling up to 20 million mph (~9,000 km/s) — never seen in any other nova. ● Data from ESO's Very Large Telescope, Hubble, the Southern African Large Telescope and TESS. ● Helium novae may be one pathway to Type Ia supernovae, the standard candles used to measure cosmic expansion. The Milky Way disc flip ● Presented at NAM 2026 by Kirill Batrakov, Durham University. ● Based on 25 Milky Way-like galaxies in the Auriga simulation suite, followed across roughly 11 billion years. ● Galaxies with the most slowly rotating stellar haloes shared a major head-on merger and a disc reorientation greater than 90 degrees. ● Our stellar halo rotates at only 10–20 km/s; the disc moves at around 220 km/s. ● The Gaia-Sausage-Enceladus collision roughly 10 billion years ago is the candidate trigger. ● Batrakov describes a disc flip as likely rather than confirmed, and is looking for independent signatures. ● Separate 2026 work led by Ling Zhu, using 600,000+ giant stars from Gaia and LAMOST, found the outer dark matter halo oriented almost vertically to the stellar disc — consistent with the disc having tilted. Skywatch ● Southern Delta Aquariids are active now, running into late August, with maximum around 30 July. ● Full Moon on 29 July means peak night is close to 98% illuminated — the worst conditions of the run. ● Best window: the pre-dawn mornings from now until roughly 27 July, after moonset. ● Radiant near Skat in Aquarius. Use Fomalhaut and the Great Square of Pegasus to locate it. ● Australia and New Zealand: radiant climbs near overhead. Best from around 2am to first light. ● North America: radiant sits low in the south — fewer meteors, but a better chance of long-trailed earthgrazers. Same 2am-to-dawn window, local time. ● Sunspot region AR4493 has grown rapidly to beta-gamma-delta...

Astronomy Daily — S05E147: "Space Mechanic" Wednesday 22 July 2026 A spacecraft with robotic arms is on its way to geostationary orbit to keep other satellites alive. A discarded rocket stage is two weeks out from hitting the Moon, and twenty-three astronomers have just asked the world to watch. Plus the first binary star system where both stars exploded, the first complete magnetic map of a galaxy cluster, and the asteroid breakup that may have bombarded three worlds while Earth froze. In This Episode ● The Space Mechanic Launches — Northrop Grumman's Mission Robotic Vehicle lifted off from Cape Canaveral on 21 July carrying three Mission Extension Pods. With two 3-metre robotic arms built by the US Naval Research Laboratory, it is designed to inspect, relocate, repair and refuel satellites in geostationary orbit. Each pod can give a 2,000 kg satellite up to eight more years of life. ● UPDATE — The Rocket Aimed at the Moon — A new arXiv preprint signed by 23 astronomers calls for a coordinated observing campaign when Falcon 9 upper stage 2025-010D strikes the Moon near Einstein crater on 5 August. North America has the best seat: 2:34am EDT, with the paper naming observers in the Americas as the ideal group. Refined impact time, predicted crater size, and why the ejecta plume may be visible even if the flash is not. ● Sibling Supernovae — Sixteen years of Fermi data reveal a faint supernova remnant hiding in the glare of the Jellyfish Nebula. The two may be the first known pair of remnants traced back to a single binary star system. ● Mapping a Cluster's Magnetic Field — Using the deepest radio observations ever made with LOFAR, astronomers have reconstructed the magnetic field of galaxy cluster Abell 2255 from nucleus to outer edge for the first time. ● The Eulalia Bombardment — A new Planetary Science Journal paper links the breakup of a main-belt asteroid to an impact shower that battered the Moon, Earth and Mars 800 million years ago — and may connect to a global freeze. ● Skywatch, Both Hemispheres — Why this week beats peak night for the Delta Aquariids wherever you are, how to catch them from the southern US and Mediterranean, and what's coming on 12 August: a total solar eclipse across Iceland and Spain, a North American partial, and the best Perseid peak in years on a new Moon.

Astronomy Daily · S05E146 · “Postcards from Mars” · Tuesday 21 July 2026 NASA’s Psyche probe phones home from its Mars flyby — data and a spellbinding month-long time-lapse — as Europe’s Plato planet-hunter clears its final test. From the Royal Astronomical Society’s National Astronomy Meeting: a CubeSat that could give us hours of solar-storm warning, and a new way to forecast the Sun’s next active spell. Plus the first pieces of the giant ngVLA radio array, and a Southern Hemisphere meteor shower to catch this week.





Story notes & sources 1 · Psyche phones home NASA’s Psyche spacecraft (launched 2023; arriving metal asteroid 16 Psyche in 2029) used a 15 May Mars gravity assist to test its instruments. The neutron spectrometer detected the anticipated count-rate enhancement near closest approach; the gamma-ray/neutron spectrometer, magnetometer and imager all performed well. Data and a month-long Mars time-lapse were released this week. ● NASA/JPL — “Psyche Mission Delivers Mars Flyby Data, Time-lapse Video” (17 Jul 2026) ● Lawrence Livermore National Laboratory — LLNL-built gamma-ray sensor’s first planetary measurements (17 Jul 2026) 2 · Plato clears its final exam ESA’s Plato — 26 cameras hunting Earth-like planets in the habitable zones of Sun-like stars — passed electromagnetic compatibility testing in the Maxwell chamber at ESTEC, its last major qualification hurdle. It’s bound for Sun-Earth L2 aboard an Ariane 6 (current target 2027). ● ESA — “Plato’s electronics ready for space” (20 Jul 2026) 3 · HENON space-weather CubeSat Presented at NAM 2026: HENON, a deep-space CubeSat that would sit ~15 million km upstream of Earth (10× farther than L1), potentially extending severe geomagnetic-storm warning from ~15 minutes to 2–3 hours. It carries the UK-built MAGIC magnetometer (Imperial College London) plus instruments from the Czech Republic and Finland, paving the way for a future European early-warning mission. ● Royal Astronomical Society / NAM 2026 — “From 15 minutes to 3 hours” (20 Jul 2026) 4 · The Sun’s “sleep” precursor Also at NAM 2026: a newly identified precursor in the solar cycle’s declining phase that could help predict the next maximum’s sunspot number. After the Sun’s active phase “switches off,” storms weaken and track a 27-day (solar-rotation) rhythm — pointing to co-rotating fast-wind streams rather than coronal mass ejections. ● Royal Astronomical Society / NAM 2026 — “How the Sun goes to ‘sleep’…” (20 Jul 2026) 5 · Building the ngVLA The US National Science Foundation, NSF NRAO and the US Naval Observatory are partnering on a pathfinder for the next-generation Very Large Array (ngVLA) — the ~266-antenna successor to the iconic VLA. The focus is very long baseline interferometry for ultra-sharp imaging and for maintaining the International Celestial Reference Frame. Construction/early operations are expected before the end of the decade. ● NSF NRAO / US Naval Observatory — ngVLA pathfinder partnership (17 Jul 2026) 6 · Skywatch: Southern Delta Aquariids Active mid-July to late August, peaking 29–30 July, with a radiant near Skat (δ Aquarii) — high overhead for Southern Hemisphere observers. ~15–20 faint, graceful meteors/hour under dark skies; suspected parent comet 96P/Machholz. A near-full Buck Moon spoils the peak, so the moon-free pre-dawn hours this week are the best window. Bright, slow Alpha Capricornid fireballs join in toward month’s end. ● Scientific American / EarthSky / American Meteor Society — Delta Aquariids 2026
