What are the potential threats of asteroids to Earth?
Asteroids pose a significant threat to Earth, as their impacts can cause widespread destruction. Understanding these threats is essential for developing effective defense strategies. Missions like Hera and DART are part of a global effort to assess and mitigate the risks associated with hazardous space rocks.
-
What instruments will Hera use to study Dimorphos?
Hera is equipped with advanced instruments designed to record the precise size, shape, mass, and orbit of Dimorphos. This comprehensive data collection will help scientists analyze the impact's effects and gain a deeper understanding of the asteroid's physical properties.
-
How does Hera fit into the global effort for asteroid defense?
Hera is part of a broader international initiative to develop strategies for defending Earth from asteroid threats. By collaborating with missions like NASA's DART, the European Space Agency aims to create a robust framework for planetary defense, ensuring that we are prepared for potential asteroid impacts in the future.
