So, how fast (relative to earth's center of mass, I guess) was the telescope traveling when it entered the halo orbit? It turns out that it was about 200 meters per second, about the speed of a commercial airliner at economy cruise. The delta-v for the course correction was on the order of a meter per second or two.
