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. Ancient

astronomers were unable to come up with a satisfactory explanation for it.

The motion is tricky. For one thing, while behaving in this strange manner,

Mars will also appear to deviate somewhat from its normal course; the

retrograde motion will appear to bring it a little below its regular orbital

track. [/ALIGN]
