SPACE PULSE

Wednesday, 8 July 2026 | 22:00 UTC Edition

⚡ TL;DR

NASA's New Horizons has awoken from its longest hibernation ever and is ready to send back Kuiper Belt science data, while a fast CME-linked radio shock at 1441 km/s rattled the sun overnight and a geomagnetic K4 warning hit Earth this morning.

A busy mix of mission milestones, sharp solar activity, and a strong week of arXiv science rounds out today's edition.

🚀 LAUNCHES

RECENT

  • SpaceX Falcon 9 Block 5 flew Transporter 17, a dedicated sun-synchronous rideshare carrying dozens of microsatellites and nanosatellites, successfully on 7 July at 07:12 UTC. [1]

UPCOMING

  • SpaceX Starship Flight 13, the second flight of Starship V3, is scheduled to lift off on 14 July 2026 at 22:45 UTC from Boca Chica; status is To Be Confirmed. [2]
  • SpaceX Falcon 9 Block 5 will launch Starlink Group 15-14, a batch of 24 broadband satellites, on 13 July 2026 at 22:38 UTC; status is Go for Launch. [3]
  • SpaceX Falcon 9 Block 5 is slated to carry SDA Tranche 1 Transport Layer E, one of six USSF Space Development Agency PWSA Tranche 1 military-communications missions, on 16 July 2026 at 20:22 UTC; status is To Be Confirmed. [4]

🔭 DISCOVERIES

  • NASA's Hubble Space Telescope released a new image of Messier 3, one of the Milky Way's most massive globular clusters, showcasing hundreds of thousands of ancient, gravitationally bound stars. [5] [6]
  • ESO's VLT has confirmed a second forming planet in the protoplanetary disc around the young star WISPIT 2, giving astronomers a rare simultaneous view of two worlds coalescing from the same disc. [7]
  • ESO's VLT and Gemini North measured winds on seven hot Jupiter exoplanets and found the strongest evidence yet that magnetic fields on some exoplanets are shaping their atmospheric circulation. [8]
  • A 28-occultation dataset spanning 2018 to 2025 has pinned down the size, oblate shape, and density of Trans-Neptunian Object (50000) Quaoar, and placed tight limits on any thin atmosphere it might have. [9]
  • NASA's COFFIES DRIVE Science Center reports a breakthrough on the solar tachocline mystery, moving researchers closer to understanding why the layer that drives space weather is so unexpectedly thin. [10]
  • An arXiv study using 26 years of Chandra data on SN 1987A tracks how the supernova remnant's equatorial ring has evolved from 1999 through 2025 in both soft and hard X-ray bands.

🛰️ MISSIONS

  • NASA's New Horizons emerged healthy from its longest hibernation ever, nearly one year; on 23 June, Johns Hopkins APL flight controllers confirmed the spacecraft is now transmitting Kuiper Belt science data collected during its dormant period.
  • ESA's Hera mission team successfully uploaded a deep-space software upgrade to the spacecraft, currently operating 140 million km away, readying it for its autumn encounter with asteroids Dimorphos and Didymos.
  • JAXA updated the launch schedule for MICHIBIKI No. 7 (QZS-7) aboard H3 Flight No. 9 (H3 F9), adding a reserved launch period as part of a rescheduling announcement issued 8 July 2026.
  • ESA astronaut Sophie Adenot began the first rope-pulling workout with the new European Enhanced Exploration Exercise Device (E4D), now installed inside the Columbus laboratory on the ISS and set for a two-year evaluation.
  • ISS Expedition 74 crew continued cartilage engineering and blood pressure studies on 7 July and began preparations for an upcoming crew swap and return to Earth.
  • JAXA's AMSR3 instrument began releasing standard water-cycle monitoring data products as of 30 June 2026, opening a new operational Earth-observation stream.
  • JAXA and ESA have formally signed a Memorandum of Cooperation on planetary defence and a cooperation agreement specifically covering ESA's RAMSES mission to asteroid Apophis.

☀️ SPACE WEATHER

  • NOAA SWPC issued a Geomagnetic K-index of 4 warning for 8 July 2026, valid from 05:28 to 12:00 UTC, flagging active but sub-storm geomagnetic conditions this morning.
  • A Type II solar radio burst detected at 22:56 UTC on 7 July carried an exceptionally high estimated shock velocity of 1441 km/s, indicating a fast-moving CME-driven blast wave leaving the Sun.
  • The most significant recent flare was an M5.8 optical class 3b event on 30 June at location S07W55, rated R2 Moderate by NOAA; it was accompanied by a brief S1 Minor solar energetic particle warning that was subsequently cancelled.
  • An earlier M6.8 flare on 21 June (S07E55, R2 Moderate) also produced a Type II radio emission at 380 km/s, underscoring ongoing active-region productivity over the past two weeks.
  • Elevated 2 MeV electron flux above 1000 pfu was recorded by GOES-19 on 13 June and had previously persisted from 7 June, a sign of sustained energetic particle enhancement in the outer radiation belt.

📄 RESEARCH

  • EXOMOON CANDIDATE DETECTED: An arXiv paper reports the detection of a planetary-mass object orbiting a substellar companion around a star, the strongest exosatellite signal yet and potentially the first exomoon-class body in a confirmed system; the authors note no prior exomoon has ever been confidently confirmed among more than 6000 known exoplanets.
  • MICROQUASAR GRS 1915+105 GOES DARK: NuSTAR observations from November 2025 failed to detect the canonical microquasar GRS 1915+105 at flux levels orders of magnitude below its historical X-ray brightness, suggesting an intrinsic and possibly permanent collapse of its accretion activity since 2018.
  • QUAOAR FULLY CHARACTERIZED: A joint analysis of 37 stellar occultations over 14 years fits an oblate ellipsoid to Trans-Neptunian Object Quaoar and constrains its density and any atmospheric shell, providing the most complete physical portrait yet of this large Kuiper Belt body. [9]
  • SKA PULSAR SCIENCE PREVIEW: A new paper argues that the Square Kilometre Array Observatory will dramatically expand the known population of pulsars in globular clusters beyond the current 345 detections, exploiting the fact that globular clusters produce roughly 1000 times more pulsars per unit stellar mass than the Galactic field.
  • XRISM MAPS CLUSTER GAS MOTIONS: XRISM/Resolve has compiled 45 direct line-of-sight velocity measurements across 19 nearby galaxy clusters, revealing diverse dynamical states and providing the first statistically meaningful sample of intracluster medium gas motions measured spectroscopically rather than inferred.
  • JUPITER JET STREAMS REVISITED: Two complementary arXiv papers examine how stable layers within Jupiter's atmosphere could fundamentally alter the vertical extent and driving of its 20-plus jet streams, challenging the standard adiabatic models and pointing to Juno and future probe data as the key arbiter.
