There are 178 days until Hera Arrives at Dimorphos, which is 25 weeks and 3 days, or approximately 4272 hours. That's 178 sleeps until Monday, November 30, 2026.

ESAs Hera spacecraft is scheduled to arrive at the Didymos-Dimorphos binary asteroid system in late 2026 to inspect the aftermath of NASAs 2022 DART kinetic impactor. Hera will deploy two CubeSats (Juventas and Milani) for close-range study, the first detailed characterization of an asteroid after a deflection attempt — a cornerstone of planetary defense research.
