🌍 NASA’s DART Mission & The Future of Planetary Defense 🚀 NASA’s DART mission (Double Asteroid Redirection Test) was the world’s first real test of planetary defense.

And it worked — proving that humanity can, in fact, push an asteroid off its collision course with Earth. This is only the beginning of planetary defense. Future systems could include: Stronger impactors to deal wit
