Experts Alert: New Strategy Required for Incoming Asteroid

NASA's monitoring of planetary defense has detected several near-Earth asteroids that now need revised risk evaluations due to enhanced tracking information. Experts caution that the existing planetary defense systems are not adequate to tackle all possible dangers within the available response timeframe. The DART mission has shown that altering an asteroid's path is achievable, yet scientists assert that the US must establish a permanent, well-funded planetary defense initiative that can address multiple threats at once.
