Mars becomes stationary on June 30. It has fallen back, as far as it will go, to the end of that Scorpius-Saturn-Mars array in which it has been a performer for the last several months.
(Don’t forget “right click – view image” to see these illustrations better.)
It ceases moving retrograde (westward, rightward) against the background of the stars; slowly resumes eastward movement. This is as good a way as any of marking the end of the planet’s time of glory, which began at the other moment when it hesitated (became stationary), nearly 40 degrees to the left. That was on April 17, so the prominent time for Mars has been 74 days.
What is really happening is that it has seemed, from April 17 till now, to be moving backward because we on our inside track were overtaking it–
Its behavior in the sky is shown in this detail from Astronomical Calendar 2016.
But look back at the first illustration – what’s that block on the horizon?
Well, it’s a house, or maybe a large first brick. Back when I had to draw these horizon scenes by hand, I used to add some scenery along the horizon; programming hasn’t allowed that, but I thought of a way to start doing it and may build it up.
