While the odds are in our favor, the universe loves a wildcard. Apophis may be tamed for now, but the sky is full of unknowns.
Deflection Strategies and Spacecraft Missions
When it comes to protecting Earth from potential asteroid threats, deflection is key. The recent success of NASA’s DART mission has proven that kinetic impact can effectively alter an asteroid’s trajectory. This technique involves sending a spacecraft to collide with an asteroid, changing its course just enough to avoid Earth. But before we can push asteroids away, we need to know them up close.
A reconnaissance mission is often necessary to understand an asteroid’s characteristics before attempting deflection.
Future missions, like ESA’s Hera, are set to refine our deflection strategies further. Hera will visit the asteroid Dimorphos to gather crucial data, validating the models used in the DART mission. This information will guide the design of new planetary defense initiatives, ensuring that if an asteroid like Apophis ever poses a real threat, we’ll be ready.
Here’s a quick look at the steps involved in a deflection mission:
- Detect and track the asteroid.
- Send a reconnaissance mission to assess its properties.
