- ● Hera launched on October 7, 2024, and will arrive at Didymos in fall 2026.
- ● The cameras have a 5.5 x 5.5 degree field of view.
- ● Angular resolution is 93.7 micro-radians per pixel.
- ● Spatial scales of 2-3 m/pixel are expected during the Early Characterisation Phase.
Optimistic Outlook
The high-resolution imaging from Hera's cameras could reveal unprecedented details about the surface morphology and composition of Dimorphos. Dedicated flybys will achieve resolutions below 10 cm/pixel.
Pessimistic Outlook
The success of the mission depends on the proper calibration and operation of the cameras in the harsh space environment. Data processing and analysis will be critical to extract meaningful scientific insights.
