Perseverance drove to the edge of an ancient Martian lake expecting a beach and found the inside of a volcano — rock that water has been through at least three separate times. Europe's Jupiter probe comes home on Monday night and crosses Australia in a fully dark sky. Two teams, using two completely different techniques, both find something hiding inside the most famous planetary system we have ever photographed — and an Australian instrument is in the middle of one of them. Plus: heavy water in an interstellar comet, and what it says about the star that made it. In this episode · LEAD — Three floods at the crater's edge. Candice Bedford (Purdue) and colleagues publish in Communications Earth & Environment: the Margin Unit at Jezero is igneous, not sedimentary, and records at least three distinct episodes of water — CO₂-rich groundwater making carbonate ridges, then silica associated with the lake, then a later hot-water event leaving fluorite veins. Habitability context, not a biosignature. · Juice returns. ESA confirms the third Earth gravity assist for 28 September — closest approach 11:45 UTC over the Indian Ocean, bending the trajectory ~20° and adding ~3.5 km/s. The spacecraft crosses Australia north-east to north-west 15–30 minutes earlier, in full darkness. · HR 8799. Two preprints in two weeks point at a fifth, inner planet — one from archival JWST aperture-masking data (~7 au, a few Jupiter masses), one from Gaia astrometry (2–3 au, 10–14 Jupiter masses). They do not obviously describe the same object. Neither is peer-reviewed. · 3I/ATLAS. A modelling paper explains the high deuterium-to-hydrogen ratio measured in March as consistent with formation around a low-metallicity — meaning old — star. · Quick hit: Starship Flight 14 still targeting 28 September; Crew-13 still 'no earlier than early October' on NASA's own page; Albania signs the Artemis Accords as the 73rd country. · Skywatch: the equinox as an instant rather than a date, the Juice pass over Australia, Venus and Mercury for the south, Mars and Jupiter before dawn for the north, and Saturn heading into opposition.

Andrew Dunkley and Professor Fred Watson also field listener questions on orbital mechanics, neutrinos, alien communication, and time dilation.The discussion is broad, but the main thread is clear: how real-world physics shapes everything from Venus’s history to the future of spaceflight and even the look of space-age uniforms.Key topicsVenus is Earth-like in size, mass, and gravity, but unlike Earth it has no moon, and the episode explores whether it may once have had one.Fred explains a modeling study led by Stephen Kane suggesting a Venus moon could have spiraled inward, crossed the Roche limit, and been torn apart by tidal forces.The team discusses what evidence might remain if Venus once consumed a moon, including possible chemical fingerprints in the atmosphere or surface.Satellite pollution is examined through the lens of reentering spacecraft, especially the growing number of Starlink reentries and their impact on the upper atmosphere.The European Space Agency’s jet-based chase of two reentering Cluster spacecraft, Tango and Samba, is described as an effort to measure reentry byproducts directly.The conversation raises concerns about aluminium oxides, atmospheric chemistry, and whether repeated reentries could have broader consequences such as ozone depletion.The final main story looks at proposed United States Space Force uniforms and why the design drew immediate comparisons to World War II-era fascist aesthetics and Starship Troopers.Andrew and Fred note how uniform design can shape perception, and why the new concept feels divisive rather than inspiring.Timestamps00:00 - Intro and setup for the episode00:41 - Venus, satellite pollution, and Space Force uniforms preview04:40 - Venus as Earth’s twin and why it has no moon08:21 - Modeling a missing Venusian moon09:20 - Gravitational tug-of-war and moon migration toward Venus11:44 - Conditions for a moon to survive around Venus12:43 - Possible traces of an ancient moon impact16:06 - Satellite pollution from reentering spacecraft17:16 - Starlink reentries and atmospheric contamination18:14 - ESA’s jet chase of reentering Cluster spacecraft20:06 - Observing Tango and Samba during controlled reentry21:45 - Why the atmospheric consequences could become controversial23:12 - Wood as a potentially more benign spacecraft material24:16 - Space Force uniforms and the first visual reaction25:34 - Starship Troopers and deliberate fascist design cues27:29 - Why the proposed uniforms feel unsettlingBecome a supporter of this podcast: https://www.spreaker.com/podcast/space-nuts-astronomy-insights-cosmic-discoveries--2631155/support.
