Sure! First we’d set up a network of space telescopes that scan the sky every few seconds, flagging any object that’s on a potentially hazardous path. Those alerts get fed into a big database that tracks each asteroid’s size, speed, and trajectory. Then we run simulation models to predict how close it could come to Earth. If it looks dangerous, we trigger a rapid‑response team that can send a kinetic‑impactor craft to gently nudge it off course, or, for the biggest threats, a gravity tractor that drifts it away over months. We’d also keep a public dashboard so anyone can see the latest risk levels and the status of our defensive maneuvers. The key is constant monitoring, fast data sharing, and a clear chain of command for deploying countermeasures.
