Hera Mission and the Target Asteroid System
Europe's Hera spacecraft is visiting the binary asteroid system consisting of Didymos and its small moonlet Dimorphos. Hera's primary objective is to closely examine the structure of this system and inspect the immediate outcome of humanity's first full-scale planetary defense test.
Measuring the Aftermath of the DART Impact
In 2022, NASA intentionally impacted Dimorphos as part of the Double Asteroid Redirection Test (DART) mission. The Hera spacecraft is now observing the crater formation, structural changes, and orbital shifts caused by the collision to gather precise measurements.
Scientific Contribution to Planetary Defense
The data collected by Hera offers unique insight into asteroid compositions and the effectiveness of kinetic impactors. These observations will play a vital role in refining orbital deflection strategies to protect Earth from potential asteroid hazards in the future.
