SPACE PULSE

Friday, 3 October 2026 — Daily Space & Astronomy Briefing

⚡ TL;DR

NASA's SpaceX Crew-13 lifted off October 1 carrying four astronauts to the ISS, headlining a week packed with planetary discoveries, deep-space milestones, and a busy arXiv. [1]

From Webb planet-collision data to ESA's Juice gravity assist and BepiColombo's Mercury approach, the solar system science cadence is high. [2] [3] [4]

  • Falcon 9 | SpaceX Crew-13 launched October 1 at 11:10 a.m. EDT (15:10 UTC) from Space Launch Complex 40, Cape Canaveral, carrying NASA astronauts Jessica Watkins and Luke Delaney, CSA astronaut Joshua Kutryk, and a Roscosmos cosmonaut. [1]

UPCOMING

  • Soyuz 2.1b | Progress MS-36 (97P) — Roscosmos cargo resupply to the ISS, targeted no earlier than November 24, 2026 at 05:03 UTC; status To Be Confirmed. [6]
  • Ariane 62 | Metop-SG B1 — Arianespace launch of EUMETSAT's second-generation Metop weather satellite, second of the B series; targeted November 30, 2026; status To Be Determined. [7]

🔭 DISCOVERIES

  • NASA's James Webb Space Telescope has provided new data on planet-shattering collisions in young stellar systems, offering observational insights into the class of giant impacts thought to have formed Earth's Moon via a Mars-sized impactor called Theia. [2]
  • ESO's Very Large Telescope confirmed a third planet, Beta Pictoris d, orbiting the star Beta Pictoris — it is 100 times fainter than Beta Pictoris b and among the lightest exoplanets ever directly imaged from the ground, found after more than 10 years of searching. [8]
  • ESO's VLT detected an anomalous moon-like object in the CD-35 2722 system that orbits a brown dwarf rather than a planet, challenging existing classification labels for moons and sub-stellar companions. [9]
  • ESO's VLT and Gemini North measured wind speeds on seven hot Jupiter exoplanets and found the strongest hints yet of magnetic activity outside our Solar System, with asymmetric wind patterns hinting at planetary magnetic fields. [10]
  • ESO's ALMA produced the largest image of its kind of the Milky Way's central region, revealing a complex network of gas filaments in unprecedented detail and opening a new window on galactic center chemistry.
  • ESO confirmed two planets forming simultaneously in the protoplanetary disc around the young star WISPIT 2, a rare direct observation of a solar system in the making.
  • NASA's APOD for October 2 features a complete mosaic of all 313 objects in the Sharpless Catalog of H II regions — the full set in a single explorable image.

🛰️ MISSIONS

  • ESA's Jupiter Icy Moons Explorer (Juice) completed a successful Earth gravity assist flyby on September 28, 2026, gaining 3.5 km/s of velocity and deflecting its trajectory by 20 degrees toward Jupiter. [3]
  • BepiColombo separated from its Mercury Transfer Module in September 2026, marking a key milestone in its approach toward Mercury orbit insertion. [4]
  • ESA astronaut Sophie Adenot completed three spacewalks in under 15 days aboard the ISS, logging a total of 19 hours and 42 minutes of EVA time; she served as EV-1 lead on her final excursion.
  • ESA's Copernicus Sentinel-1 captured radar imagery of Typhoon Surigae's sea-surface conditions using false-colour polarised imaging, showing the intense wind field beneath cloud cover.
  • ESA's FLEX Earth-observation satellite launched aboard Vega-C alongside Sentinel-3C in September 2026, a dual-payload milestone noted in ESA's monthly roundup. [4]
  • JAXA's H3 rocket Flight No. 9 is scheduled to carry the MICHIBIKI No. 7 Quasi-Zenith Satellite (QZS-7) into orbit; launch window details were confirmed in August 2026 with a reserved period extension issued in July.
  • JAXA's Hayabusa2 set a new record for closest approach during a solar system body flyby mission on July 5, 2026, and achieved a world-first laser ranging measurement during the asteroid encounter.
  • NASA opened applications for its next class of Mission Control flight directors at Johnson Space Center, citing the role's importance for sustained human lunar exploration under Artemis.
  • NASA's INSPYRE campaign investigated a pyrocumulonimbus (pyroCb) cloud triggered by the Wildhorse grass fire in eastern Idaho, capturing rare data on smoke injection into the upper atmosphere.
  • ESA's Paranal solar ESPRESSO Telescope (PoET) achieved first light in April 2026, pairing with the ESPRESSO instrument to study the Sun as an analog for exoplanet host stars.
  • The 77th International Astronautical Congress (IAC) opens October 5 in Antalya, Turkiye, running through October 9; ESA will participate with more than 6,000 attendees expected under the theme "The World Needs Space."
  • October skywatching highlights from NASA include Saturn at opposition, the Orionid meteor shower, and the Moon passing close to the Pleiades.

☀️ SPACE WEATHER

  • NOAA SWPC issued a continued high-energy electron alert (ALTEF3) in early September, with the 2 MeV integral flux exceeding 1,000 pfu beginning August 31; daily maximum flux peaked at 830 pfu on September 4.
  • A separate ALTEF3 event began September 10; flux peaked at 7,008 pfu on September 11 — an exceptionally elevated reading — and remained above 1,000 pfu through at least September 14.
  • NOAA issued a Type II Solar Radio Emission alert on September 3, indicating a fast coronal mass ejection with an estimated shock velocity of 1,359 km/s.
  • A G1 (Minor) geomagnetic storm watch was issued September 14 for September 15 and 16, with a K-index of 4 observed and a formal K4 warning valid through September 14 23:49 UTC.
  • Note: All space weather alerts in the feed are from September 2026; no new SWPC alerts have been issued in the ~24-hour window ending October 2, 2026 at 22:00 UTC.

📄 RESEARCH

  • XRISM/Resolve dark matter search: Researchers propose using low-count-rate serendipitous XRISM Resolve observations to hunt for a keV dark matter decay line, searching the 3.48-3.56 keV band toward the Milky Way halo; initial bounds already exceed prior limits despite shorter exposure.
  • DESI DR1 bispectrum cosmology: A joint full-shape power spectrum plus bispectrum analysis of DESI DR1 luminous red galaxies and quasars breaks parameter degeneracies left by power-spectrum-only methods, tightening constraints on large-scale structure growth.
  • DESI dark energy vs. modified gravity: A new paper asks whether DESI BAO combined with CMB data is pointing toward dynamical dark energy or a one-parameter "cosmic glitch in gravity" model where the gravitational coupling differs slightly between early and late universe — the glitch model fits with only one free parameter.
  • ULX hard lags discovered: Astronomers report kilosecond hard X-ray time lags in the new pulsating ultraluminous X-ray source candidate NGC 7456 ULX-1 — hard lags are rare in ULXs and may constrain the super-Eddington accretion geometry around compact objects.
  • JWST Lyman-alpha reionization bubbles: Analysis of JWST-measured Lyman-alpha emission fractions at redshifts 6 to 14 is being used to map the size and timing of ionized bubbles during cosmic reionization, connecting individual galaxy detections to the global neutral hydrogen fraction.
  • SolarProp 2.0 cosmic ray tool: An updated open-source framework solves charge-sign-dependent solar modulation of cosmic rays using stochastic differential equations, making state-of-the-art heliospheric transport modeling accessible to the broader community.
  • Titan cryolava flows: A new fluid-dynamics study models how cryolava or impact melt flows across Titan's surface, connecting the moon's young geology and isotopic anomalies to possible interior-surface material exchange — relevant context for the upcoming Dragonfly mission.
