Pretty cool they were able to measure the change in velocity of an object 6 million miles away with millmeter/second resolution. Not cool that it only slowed down a few mm/second though
Actually, a few mm/sec is quite a lot. That could easily be more than enough to deflect an asteroid from hitting earth. That few mm/sec will accumulate over the time it takes the asteroid to travel six million miles.
