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.

Show notes Time Lets Go of the Sky On 15 October 2026 the 28th General Conference on Weights and Measures in Versailles adopted Resolution 5: UTC becomes continuous on 20 May 2027, ending leap seconds, with the UTC–UT1 gap allowed to reach one hour. The driver: a growing chance (about 30% by 2035) of a first-ever negative leap second. Resolution 6 starts work on an international lunar reference time scale traceable to UTC; Resolution 4 prepares an optical-clock redefinition of the second for 2030.
