What are the key findings from recent asteroid missions?
Recent missions, particularly NASA's DART and the newly launched Hera mission, have provided significant insights into asteroids. DART successfully altered the trajectory of the Dimorphos asteroid, demonstrating a viable method for planetary defense. Hera will analyze the impact crater created by DART, focusing on its size and depth, which will enhance our understanding of asteroid properties and improve future interception strategies.
