This week saw several space weather signals, including a geomagnetic storm (GST) on July 4, with 12 new connections. Multiple coronal mass ejection (CME) signals were detected on June 30 and July 1. Hubble articles detailed merging galaxy clusters, a swarm of galaxies, and a starry chandelier. Webb observations included an exoplanet getting roasted, clues to Comet 3I/ATLAS's origin, and millions of stars within the Cigar Galaxy. Ariane 6 had its first liftoff with powerful boosters on June 17, carrying Amazon Leo flight payloads. Preparations continued for a Swift reboost mission, with a LINK Spacecraft set for the task. Mars exploration news covered NASA Langley's role in Red Planet landings and the groundwork for human missions.
