Looking at the moon from earth, it takes up around 1/2deg of field. The picture is around moons, or 1.5 deg of sky.
The earth will rotate 360 degrees in 24 hours. 1.5/360*24=0.1 hours (6 minutes). It takes 6 minutes for a stationary object to appear to move 1.5 degrees.
On April 20, the moon will be at it's first quarter. (same phase as picture)
Go outside and look at it.
Wait 6 minutes and look at it again. Does it look any different?
The moon moved roughly the same angular amount that the space station did in that picture.
