Hopefully they redirect it the way they want to.
In this case, it is actually a small asteroid that is a moon of a larger one so they are only going to nudge it enough to change its orbit around the "parent". So no risk.

When we ship bulk products from one part of the world to another, does that distort our gravitational fileld a little bit?

Probably not enough to be detectable save on very sensitive measurements. And usually there are multiple bulk shipments going in multiple directions so probably all evens out in the end. Now, I do wonder how much the displacement of water by all those massive ships affects the water levels, esp. in confined waterways like the St. Lawrence Seaway. In the ocean it is probably negligible but in more confined spaces, it could be significant.

A good piece on DART (the asteroid deflection mission) from Scott Manley. He explains rather well why they are using this two-asteroid system rather than a standalone asteroid. Also makes the point that is the first real interplanetary mission launched by a SpaceX Falcon rocket. Launch is set for tonight from Vandenberg AFB in California.

FYI, Dart lifted off successfully the other day and is now off on its mission. The actual impact is due to happen in September 2022, with a cubesat provided by ESA watching the fun.
