Space Nuts: NASA's Starliner, Retrograde Exoplanets, and the Square Kilometre Array In this thought-provoking episode of Space Nuts , hosts Andrew Dunkley and Professor Fred Watson delve into some of the latest developments in space exploration. They kick off with NASA's recent decision to stick with Boeing's Starliner for additional crewed missions, despite its rocky history. The conversation then shifts to the intriguing discovery of the exoplanet GJ 3090B, which is orbiting its star in the opposite direction, raising questions about planet formation and dynamics. Finally, they explore the innovative designs behind the Square Kilometre Array, examining how nature-inspired layouts may enhance its functionality while addressing technical challenges. Join Andrew and Fred Watson as they unravel these cosmic stories with their signature blend of wit and insight. Key topics - NASA's ongoing collaboration with Boeing for the Starliner missions and its implications for future space travel. - The unusual retrograde orbit of exoplanet GJ 3090B and what it reveals about planetary systems. - The design and challenges of the Square Kilometre Array and its nature-inspired antenna layout.

Show notes The Moon Is Still Shrinking Watters, Banks, Nypaver and Robinson (Planetary Science Journal, 14 Oct 2026) map more than 10,000 young thrust faults — ~8,900 lobate scarps and 2,000+ small mare ridges — with LRO's camera. Together they record about 42–46 m of radial contraction over the last ~400–800 million years, at most ~11 cm per million years. That's less than thermal models predict, pointing to a thick, porous, insulating megaregolith (or a strong elastic lithosphere) that delayed faulting. The ~4 MPa stress matches Apollo shallow-moonquake stress drops, so faults may still be growing today — relevant to siting lunar bases. A Soil Map for Mars University of Sydney PhD student Daniel Irving and Prof. Alex McBratney (Catena 275) classify almost 800 million Martian locations into 10 realms, 100 assemblages and 2,000 forms of 'areths', mapping 92% of the planet. Top candidate for plant growth, Nohibareth (score 0.93; ~72% clay, pH 6.8), covers 0.14% of the surface around Tharsis, Arabia Terra and Elysium. Candidates for study, not greenhouse sites; perchlorate and nitrogen not yet included. Euclid Finds Its First Comet ESA's Euclid discovered C/2026 S1 (Euclid) in Deep Field North images from 16–24 September, flagged by Mikko Pöntinen's moving-object software and confirmed by the Minor Planet Center on 8 October. ~1.3 billion km away on a steep, thousands-of-years orbit. Uranus and Neptune: Cousins, Not Twins Briand, Hue, Mousis, Cavalié et al. (A&A 714, A364) use upper-tropospheric carbon monoxide, including ALMA data, to infer deep oxygen: Uranus ~47–177× protosolar, Neptune ~182–342×. Contrasting C/O ratios suggest Neptune's building blocks formed closer to the Sun. Accepted version online since late August. Quick hits MMX launched 04:41:03 JST 20 Oct on H3 F10; separation ~71 min 13 s; JAXA confirms the spacecraft is operating normally. Roman's Wide Field Instrument focused to 63 nm RMS against ~90 nm required. Artemis II heat shield: 9 char-loss spots vs 103 on Artemis I. Hera's BRM-2 burn Thursday 22 October. Skywatch Orionids peak 21–22 Oct — watch between moonset and dawn (moonset Thu morning: 03:38 Sydney, 03:22 LA, 03:12 NY, 02:49 London). Mercury 16.5° up at civil dusk from Sydney.

MMX: A Round Trip to Phobos JAXA's Martian Moons eXploration mission launched on schedule on H3 Flight No. 10 at 04:41:03 JST on 20 October 2026 (19:41 UTC 19 Oct; 06:41 AEDT Tue; 15:41 EDT / 12:41 PDT / 20:41 BST Mon). Mars orbit August 2027, Phobos quasi-satellite orbit from September 2027, Idefix rover (CNES/DLR) release early 2029, landing and sampling 2030, and at least 10 g of Phobos returned in 2031 to South Australia. Eleven science instruments including NASA's MEGANE. The aim: settle whether Phobos and Deimos are captured asteroids or debris from a giant impact on Mars. Half a Giant Mirror ESO reports that nearly 500 of the ELT's primary-mirror segments are now at Paranal — more than half of the 931 being made (798 plus 133 spares for continual recoating). Safran Reosc is finishing a segment a day and the last one is in production. The ELT is more than 75% complete, with first observations with scientific instruments planned for late 2030. The Window That Closes Carr, Cen and colleagues (Nature Astronomy, 15 Oct 2026) used Hubble/COS spectra of six matched local starbursts to show ionising light escapes most in the first few million years, before supernova-driven winds load the outflow with neutral gas and shut it down. Escape fractions fall from ~21% (mean age ~2.7 Myr) to under 0.4% (~5.4 Myr). Preprint first posted October 2025. The Treble Clef Rises Again Botteon et al. (A&A; NASA/Chandra release 14 Oct) show VLSS J0318.9+5755, behind the Milky Way's plane, is a radio phoenix in a merging cluster at z ≈ 0.117: an old black-hole outburst re-lit by a cluster collision a few hundred million years ago. Spectral index above 4 between 400 and 650 MHz; electrons ~190–200 Myr old. Preprint from July. Quick hits Hera's 93-minute BRM-1 confirmed within parameters; BRM-2 on Thursday 22 October. Sentinel-3C's first images and altimetry. Swift: no NASA re-entry date yet. Skywatch Full Moon 26 Oct 04:11 UTC. Orionids peak 21–22 Oct: go after moonset (03:38 Sydney, 03:22 LA, 03:12 NY, 02:49 London on the 22nd). Mercury 17° up at civil dusk from Sydney (21 Oct). Venus inferior conjunction ~24 Oct. Moon ~6° from Saturn ~24 Oct. Mars–Jupiter 10.8° → 8.0° pre-dawn. Always use ISO 12312-2 certified filters for any solar viewing.
