It’s a huge milestone for the field of planetary defense; it establishes that it may be possible for humans to significantly change the path of a potentially hazardous asteroid — especially if we have warning that one is on the way.Is Dimorphos wobbling?Once they have that information, the modeling will get even more intense; they’ll take the information from the observatories and run it through physics simulations again and again until they have a pretty good idea of what happened.“The single most important factor that we need to know is which ones out there are potentially dangerous, and when might they be potentially dangerous,” said Lori Glaze, director of NASA’s Planetary Science Division.NASA is working on the Near-Earth Object Surveyor Mission, which would specifically look for these kinds of hazards."
