  • The surface of active asteroid (3200) Phaethon, parent body of the Geminid meteor shower, reaches temperatures sufficient to destabilize hydrated materials. Here, the authors show that the northern hemisphere and the equatorial region of this asteroid reveal no evidence of hydration in the near-infrared spectra.

  • Double Asteroid Redirection Test (DART) mission impacted Dimorphos to test asteroid deflection. Here, the authors show that post-impact spectra largely match pre-impact properties, with only subtle variations probably linked to mutual events and to the evolution of the ejecta dust.

  • 2023 CX1 is the only L-chondrite-like asteroid analysed from space to ground. It catastrophically fragmented in the atmosphere, depositing 98% of its energy in one burst—an unusual, high-risk fragmentation mode with implications for planetary defence.

  • Combining the infrared capabilities of JWST and synthetic tracking techniques, the detection of some of the smallest asteroids ever observed in the main belt is reported; their large abundance reveals a population driven by collisional cascade.
