For the past few weeks, Mars has appeared to slow in its eastward trajectory, almost seeming to waver, as if it had become uncertain.
On Wednesday, July 30, that steady eastward course will come to a stop. Then, for the next two months, the planet will move backward against the star background - toward the west. On Sept. 29 it will pause again before resuming its normal eastward direction.
All the planets exhibit retrograde motion at one time or another.
