John Batchelor and I welcomed DR. NANCY CHABOT of the DART team at the APL to discuss the initial success of the DART impactor in moving the Dimorphos orbit. It appears that Dimorphos was moved closer to Didymos to shorten the orbit time around the larger asteroid by a half-hour which means it would have a change in its path toward Earth were this asteroid on a collision path with Earth. Our guest talked about calculating the orbit before and after the impact, the material Dimorphos was made of and how that might impact a future deflection mission. Also discussed was the importance of the advanced warning time needed to move an asteroid from hitting into Earth. The longer the warning the time the better. She said even decades might be needed for a larger asteroid. The general subject of planetary defense was talked about along with other possible methods of protecting Earth from a possible asteroid or large meteor impact.
